I think the group consensus is that Leif Johnson (Autoworks NW in Woodinville) is the area 928 wrench of choice.

That's where I dropped mine yesterday to get the damage assessed.

Ok, Is it possible to loose your power steering with no other problems
and
still have plenty of fluid? Last week I pulled the shark out and found
that
the battery had died after not being driven for 5 weeks. So, I had to
jump
it. But I took it out for a couple of hours and everything seemed normal.
This weekend I took it out and I could swear that the power steering is
gone.

Re: Power Steering

 

You can put a gauge in the line and see if you have pressure... there are
check valves in the pump that might be bad too, they are probably intergrated
in the pump though. But I now from my last car that the lines run all over,
I had a leak and could not find it in the line

Hey, Tom.

It was nice to run into you at the track! A lot of nice cars and a good
sunburn. I was disappointed I didn't get to see the new drop links on
Adam's car, though I figured he wouldn't show.

As for Adam's request, I don't know whether Tom took any pics. I have one
that proves handily that digital cameras don't handle back-lighting nearly
as well as the human eye (read: mediocre pic). Photographic evidence that
my car *is* occasionally clean:



I'm sure I'll manage a better picture sometime soon. I'm having trouble
believing that it's 13+ years old.

Curt


Re: Power Steering

 

Ray: If the pump failed it would have fluid but the no pressure. Power
steering is a closed loop hydraulic unit. so if the pump is bad or failing
the fluid would pass through with no pressure.

Hey Calvin,

I think I can answer your query regarding drag racing.

The reason we're racing is because we are a bunch of mindless idiots that
are fanatical about our cars, believe them to be one of the finest and
most
desirable automobiles on the road, like to test the limits of our sharks
and ourselves, and above all else, we like to hang out together and watch
each other do silly things. (Can I get an AMEN BROTHER?)

With regard to the half shaft issue, I've inserted an (edited) email
exchange between myself and DR which all of you might find of interest:



Hi Adam,

Darn you guys are going to have some fun, this looks so tempting to me
it
might be worth flying out just to watch !!!!
....and I'd send you the airfare if I didn't think you'd get flamed on the
list for the next two months straight for taking a weekend off just to
have
a life :).

Wally was nice enough to impart some comforting words of wisdom on a
slight
mishap I had on my Nology wire install. Just to show my thanks for that
and for 928SP's ongoing support of my 928 habit, I'm going to be sending
y'all (trying my best southern accent here) a Pac NW Shark Drags T-shirt.
Since you folks won't be here for the event, I thought I'd send a piece of
the event out to you. They should be ready in the next couple weeks. I
figure with you getting the event shirts coupled with all of the orders to
replace broken half shafts after the event, it'll be just like you're
here.

In truth I'm hoping for no mechanical failures, and will probably be
giving
an "it's all about consistency, not quick e.t." speech prior to everyone
running. I'd feel really terrible of someone damaged their shark as a
result of the event.

So, can we get a bulk discount on those half shafts?

Discount heck, if anyone breaks theirs at your event I will sell them
the
parts they need at my COST !!!
Now, now,..... I don't want to tell them that. Knowing these guys they'll
probably interpret that as an incentive to be breaking parts. :)

I kid you not when I talk about the competitiveness of these guys, they're
insane!

{End email}

........so, there you have it Calvin. The half shafts are covered :).

There are several different reasons for owning a shark, and I don't think
that one is more valid than the other. You can buy a low mileage show
piece and save it for sunny weekends, you can buy a high mileage mule and
run it through the paces (yours truly). Or you can do both with the same
car (Redinger, you kill me!)

I don't discount pride in ownership at all, for many having a shark in the
garage is the most satisfying part of ownership. (I'm not saying that this
is you, it's just an example).

For many of us locally here, pride in ownership is just a piece of the
pie, our intrigue goes into other areas like performance driving and
upgrades.

One of the reasons that I enjoy putting together these gatherings is that
there are so many local owners that share my philosophy of pushing these
cars deep into their performance envelope and trying different means to
extend that envelope.
Its kind of self serving, but I organize these Pac NW Gatherings because
it
an opportunity for me to share ideas and stories with like minded
individuals.

I realize that many out there don't share the same philosophy regarding
their sharks, and prefer to preserve them and drive them occasionally.
The
first local gathering, The 928 Owner's Showdown which was held last fall,
was tailored to allow all local owners to participate in an event (Kart
Race) regardless of everyone's personal philosophy about their own car,
and
just share in our pride of ownership.
I wanted an event designed around getting people together without putting
any of the sharks at risk. Much to my suprise, I discovered a lot of
owners were interested in pushing their cars and discovering and improving
performance benefits much like myself. We did a dyno day next. I couldn't
believe the amount of willing participants that attended. As almost a
joke, I threw out the idea of bracket drags for the next event. I really
was hit with a sense of pride when there was an almost unanimous "when's
the date?" for a reply.

Breakage is costly, there's no doubt about it, but a lot of us accepted
that long before we purchased our sharks.

A lot of the crazy things we do with our sharks provides R&D opportunities
to help the 928 community as well. Louie is actively developing and
designing modifications for our cars, some of which I can proudly say he
tested at our last event. Ultimately, these performance items may end up
on your car. If you have a set of steroid drop links, than you already
have benefitted from someone else's high performance testing.

I hope this kind of explains things Calvin. I wouldn't fault any shark
owner for not wanting to race his car, I can see how it may be seen as
abusing the vehicle. For some of us though, part of ownership means
finding shortfalls in our cars and improving them.

So, are you going to come out and watch the carnage on the 25th? Someone
may need to ask you for a ride home if their shark goes home on a flatbed.

Re: A day with ProFormance

ADAM BIRNBAUM
 

Hey Calvin,

Nah, I didn't think you were trying to pass judgment or anything, I just
wanted to explain how I feel about the use of my car.

Yeah, the 2.02 is definitely not made for a quick quarter. All the same, it
is very amazing that with 2.02 gears, the 928 can still break into the 14's
and top out at 165mph. I never tracked any of my high school hotrods, but I
know from street racing others who had, that a 14 second car was mighty
quick. I think Louie Ott's GT may be 13 second material, and I know that
none of my high school comrades, with their big block mopars or full tilt
rat motors could shift their way into the 13's with anything short of 4.11
gears.

Does it effect these cars much by running them hard?, well your timing
couldn't be better (sarcasm). One of our shark brothers came up with a
little rod knock last time he was on the track. My own shark just started
an interesting "whirring" sound which I'm going to get checked out hopefully
tomorrow. I think I may try disconnected all of the outboard gear
(compressor, alt., etc) first to make sure it's not something silly before
letting the local shop ding me for a diagnosis. I don't believe that my
noise is track related (it hasn't been on the track for about a month), and
has been, and actually still is, running great. (except for the noise of
course).

I haven't seen the black GTS. I know that there was a black GTS at Park
Place Motors at the same time that Chris Ford bought his '91 S4. Chris
actually test drove the car, got the OK to buy it from his S.O. (what a
woman!, he's a lucky guy), but opted to save the extra cash and bought his
very clean S4. I'm wondering if its the same car.

You oughta come out to the drags if you can. If nothing else, it would be
good just to meet you in person. The people that are going to participate
are probably some of the funnest people I've had the pleasure to hang out
with.

As far as the drags being hard on the cars, I think it depends on the
driver. I know that speaking for me, I won't be power braking, neutral
dropping, or doing anything nuts. I'm accepting that my car is going to
pass in the mid 15's, and am just going to try to run consistently. The
extra 4-5 tenths that abusing the car would get me isn't going to get me any
closer to a trophy, except for maybe the "shark chum" award. (more on that
at the event). Just like Tom had stated in an earlier post, I'm treating the
drags just like any on ramp on a friday afternoon. The only difference is
the "on ramp metering device" at the strip has a few more bulbs on it than
the ones on I-5. Launch on the last amber, put it to the floor, watch the
tach stroke redline a couple times, shut her down. No Problem.

Come on out if you can,

-Adam

Hey Tom,

Sorry I missed you and Curt today. I really didn't wan't to press my luck
with the exciting new sound that my shark making. I'm saving grenading the
engine for the shark drags :).

Actually, I'm going to take it to the dealer for diagnosis tomorrow, and see
what they think it is. I'm thinking water pump, which is still under
warranty, so we'll see.

It would be nice if someone would post pic's of Curt's new wheels, I'd
really like to check 'em out.

I'll post the result of the diagnosis from the dealer.

Hi Everyone,

After Adam mentioning about the PCA DE at SIR this morning, I decided
to grab the kids and head to SIR for a day of shark watching. Get
there early on a nice and sunny day and don't see any sharks around.
Park and walk a bit and see a couple off in the corner. One was a
pristine 88 5-sp in Granite Green Metallic (you have to see this
color in person) very nice car (about 100000KM if I remember right).
Owned by Peter (can't remember his last name) and his wife (Im
really
bad with names) from Vancouver Island. He just recently sold a race
ready 911 with trailer and all the goodies and picked up this 928. It
had a green interior but it fit well. The car was more of a
gray/green. His wife had it out on the track (the RMB sounded really
good during the passes).

Anyway took a break for some early lunch (kids were acting up) and
when I came back there was this white 87 with Kinesis rims and SO2's
all around (what a fat setup and I mean fat not Phat) even though
both
apply. I of course recognized fellow Seattleite Curt Nichols car.
What an amazing difference. Made my stock rims look like bicycle
wheels. Very nice setup. Found Curt in the grandstands checking out
the DE too.

On the way out found the owner of the bright blue 79 Euro (he also
came down from Vancouver Island). Talked to him a bit (forgot his
name too>>>) but the car was basically stock except for headers and a
brand new borla setup (no cats here). He had stripped the entire
interior out, took out the headlights, replace one set of fogs with
ducts for brake cooling. Said he had it down to 2800lbs.

Also saw the older red 928 (I think it was a 83 or so) with a heavily
modded 4.7 but didn't get a chance to check it out. Got some more
pics of the cars and will post them once the film is developed.
Didn't see Adam or Lloyd (kind of expected not to see him) Did you
get the diagnosis on the engine yet?? I guess that goes for both
guys, Im seeing a trend here, take your car to the track, spend
lots of money on parts and then have your engine expire ????!!!!!??

Yikes better remain a spectator, Nope just kidding, Hope all is
well with your cars.


All in all a nice day in the sun, met some fellow shark owners and
saw
some really nice Porsches.


Take care

Hi Adam, or should I say good morning,


Im not sure about your sound, but my tranny make a whirring noise too ususally
only after start up and only if I pull the selector to 2...... Ive sat a light
and listened to it thinking what the heck and pushed the selector to 3 and it
disapeared?? Could be a pump in the tranny just pumping things up to
pressure ??? Seems to go away after things heat up.

Good luck at the track.

Hello everyone,

As I was backing out of my garage this morning, on my way to another

it out? Of course not. I needed to run by my office first, so I thought
I'd check it there in hopes that my prayers to the shark gods along the way

I know there are million things it could be, and without hearing it

The noise is a low toned whirring noise, that increases with engine RPM.
For the life of me, I cannot pinpoint the source of the sound. It seems to
emanate from whatever part of the engine I'm listening to. I am convinced
that there is some kind of audio warping field surrounding the engine that
was designed by Porsche, which requires a factory stethoscope to discern
the source of odd engine noises. No doubt installed to protect shark and
foolish but somewhat mechanically inclined owner from doing harm to one
another.

The sound is reminiscent of a small block Ford with a burnt out water pump
bearing, only much more quiet. (I never understood the need for the weep
hole in those things) I say Ford because I replaced many in my big
brother's armada of Mustangs, but never had to in any of my chevy's (yes,
that's a dig) My water pump was replaced about 4K miles ago, so it should
still be under warranty if that is the case.

So, for my eternal gratitude, and a free can of Spam or chipped beef (your
pick), anyone want to take guess? Also, any ideas on how to a make or
where to purchase a stethoscope so I can do a better job of pinpointing?

From: Wally Plumley <wplumley@...>

X-Message-Number: 7

John had some questions about suspension:
1. The Spec Book talks about coloured markings on the springs to
differentiate between spring lengths. Where abouts are they?

The colored markings really designate spring rates, rather than lengths.
They are hand-painted ?" wide paint stripes, usually located on about
the second or third coil from the bottom. Use a spray cleaner (409,
Fantastik, etc.) to find them. The codes are in the shop manual.
2. I do not know whether the shocks are Bilstein or Boge. How can I tell
without removing? (They are black in colour).

Surest way to tell is to clean the bottom of the shocks with your spray
cleaner and read the name. You can tell by appearance, but the
differences are subtle until you see both.
3. If I have the right combination of springs and shocks then one/both must
be worn out. The car has done 32,700ml. What should I try replacing first
or should I do both at the same time?

Shocks don't affect ride height, except for VERY minor change when gas
pressure shocks lose their internal pressure. At 32K miles, I doubt that
you need shocks - although a lot of people like the feel of firmer (i.
e. Koni) shocks.
Suspension springs DO NOT "wear out". (Valve springs on some cars can
and do wear out through fatigue. Apparently this is not a big problem on
928s.) The only change that normally happens to springs is a small
change in free length, which can change ride height. The only
detrimental factor in the change in free length is a slight loss in
suspension travel, which is not a problem in street driving.

My suggestion is to adjust your ride height and align your suspension.
To measure Ride Height:
1) What and Where.
Front: There is a small flat machined area on the bottom of the cast
bracket that holds the rear of the Lower Control Arm, between the ribs.
This pad should be 180mm +/- 10mm from the floor. There should be a max
difference of 10mm from left to right.
Rear: There is a small flat machined area on the aft bottom of the large
u-shaped bracket that holds the lower transverse control link (the large
flat blade). This pad should be 173 +&#92;- 10mm from the floor. There
should be a max of 10mm difference from left to right.
2) How to Measure.
First, and most important: You CAN NOT measure, jack the car to change
the ride height, lower the car and remeasure! You MUST either measure,
jack and change, then drive the car for at least three or four miles
before you remeasure; OR measure, change ride height WITHOUT jacking the
car, then remeasure. The 928 takes several miles of driving, or using
special tool 10-222A to pull the front end down 60-70mm for one minute.
Yes, they are serious. Yes, if you don't do it one of these two ways,
you will screw up your ride height - and the same thing applies to front
end alignment.
You will need a tool that you can use to measure the ride height points
while manipulating it at arm's length under the car. One possibility
would be a pair of yardsticks, bolted together near the centers using a
wing nut, making a kind of three-foot scissors. Slip this under the car
to the machined pad, put one tip on the floor and one tip on the pad,
being sure to keep them plumb, tighten the wing nut, pull it out and
measure the height.
3) How to Change the Ride Height.
Most 928 springs are adjustable. These have a round, notched, threaded
nut around the shocks under the lower spring seats. Ed Ruiz found a tool
to adjust these nuts - a "Motion Pro Single Shank Nut Spanner, 08-029"
at a motorcycle shop for about $16. (Someone bought one of these tools
by mail order from a motorcycle dealer in Pittsburgh (tel.
800-860-0686). They refer to it as an "ATV Shock Tool" part no. P529.
It's made by Motion Pro whose own part number is 08-029. Cost was about
$14 plus shipping.) Turn the front wheels all the way left or right,
lube the nut area well with a penetrating spray lubricant, and turn the
nut right to raise, left to lower. You can get to the rear (also lubed)
with only a little stretching.
Adjust the height all the way around and remeasure. When you think that
you have it right, drive the car for three or four miles and remeasure.
If your Spring Struts are not adjustable, the only way to change ride
height is to change springs or to disassemble and add a maximum of two
spacers to the lower spring seats.
4) After you get the front ride height set, adjust the toe-in. Easiest way
is to "string" the car, ala NASCAR. Use any four convenient objects to
securely hold two strings that run beside the car, an inch or two from the
tires. Warning! The track is rarely the same front and rear, so don't use the
rear tires to set your string! Measure the distance between the strings in
front of and behind the car, and make these distances identical. Make the
distances between each rear tire and its string identical. Make the distance
between each front wheel center and its string identical. Straighten the
front wheels with the steering wheel. Measure the distance from the front of
each tire to the string and the distance from the back of the tire to the
string. Try to be very consistent on where you measure from on the tires. Do
the simple math to get the difference between the front and back measurements
on the front tires. Adjust the tie rods on the steering rack to get the
tires almost straight ahead, with the smallest amount of toe-in that you can
measure. This will be close enough until you can find an alignment shop that
will align your car WITHOUT JACKING IT UP. If your alignment shop can't or
won't do the alignment without jacking the car up, find another shop.
4) Personal Opinion
Set your car at the factory ride height. This is where the suspension
was designed to work. My car was lowered by the Previous Owner. Raising
it to standard height very noticeably improved both the ride and
handling. Low may look cool, but it doesn't work well!

Subject: adj. ride height (long)
From: Joe Rausa <jgrausa@...>

X-Message-Number: 20

28ers:
Thought I'd pass on my experience adjusting the ride height on my '89S4.
Here are a few "tips".
1) The Pro Motion tool (avail. @ Bob Tracewy's World of Cycles - Moon
Township, PA 412-269-9999, $22.41 delivered) that Ed Ruiz suggested is a must.
2) Before you start, get a full load of fuel - this makes a difference
3) Make certain you are working on a completely level surface - this makes a
difference
4) The night before you are to begin, get out that new can of WD40 and be
generous. The part that sticks is the area on top of the adjusting nut where
it makes contact with the lower spring plate - this makes a
BIG difference
5) Take height measurements before you start. (I'm confident that you
engineering types know about baseline and all)

6)Get a decent measuring tool - I used an expandable pointer (remember
these, before laser pointers) and a tape measure. (Hey Ed, how 'bout a
metric tape measurer for my XMAS stocking?) To convert inches to mm,
multiply by 25.4 ie: 6 ?" = 6.25 x 25.4 = 158.75mm
7) Begin with the corner that is furthest out of spec (or relative to the
other corners). This will probably be one of the front springs.
8) If your front is low like mine and you're running out of adjustment
capability (seeing more than 5 threads below the nut), you may be able to
lower the rear to help you get the front up.

Side line: I made the mistake of beginning with the rears because they
looked the most accessible. I was going to bring them up to "new" ride
height 170mm. Well, once I got there, I had put so much additional
weight on the opposite front, I couldn't adjust to within spec on the
fronts. So after working for 2 hrs making 1/8th turns on that friggin'
nut on both rears, raising them 10mm, I had to bring them back down to
"unload" the front springs.
9) Take a look at what the factory manual says about the 180mm (front) and
170mm (rear) target settings. These are for NEW cars/springs. "downward
tolerance can vary by 10mm more" (read carefully as the manual is unclear,
the xtra 10mm less may only apply to the maximum setting)

10)Wear gloves - if my knuckles could talk they would be screaming at
me. Sometimes the Pro Motion tool slips off the nut while you are giving
it "full reverse thrust" (another language lesson for my kids). Also,
when pushing the tool, I put a nice blister in the palm of my hand (yes,
it was the Pro Motion tool that gave me the blister)- this makes the
BIGGEST difference
11)A reasonable objective would be to minimize the height variance on each
front corner, then on each rear corner. I was able to acheive this objective,
LF - 152.4mm RF - 152.4mm, LR - 154mm RR - 154mm, but I fear that no further
adjustment will get me closer to spec, much less "new" ride height. New
springs are in my shark's future. Gratefully, Dave Roberts has the antidote
for my LRS (low-rider syndrome).
12) Finally, once you think you've got it, take the car out for a little
spin; a couple semi hard stops, a couple quick corners, then back home.
Re-measure, guess what, bring out that Pro Motion tool and get back at it,
you ain't done.
Hey, who said it wasn't fun??
Merry Xmas,
Joe Rausa and "Ray" (sitting higher, but not quite right yet)


Re: Any ride height tips?

Curt Nichols
 

BTW, I made ground-to-fender height measurements before and after mounting
my new wheels to the car. Some tidbits I found interesting:

- After lifting but before settling, the front sat 2.5" (63mm) higher and
the rear sat 1.5" (38mm) higher.

- After 60 miles of driving the car sat about .25" (6mm) higher at the
fender (all around) than it did before the wheel change. This could be due
to the slightly larger tire diameter, full tread depth, or dumb luck.

- When I started, the fenders sat .25" higher on the left than on the
right. I park immediately next to a concrete pillar, around which I make a
tight left turn. I have limited space to work, so half way through I
backed the car out and parked it tail-first, repeating the parking maneuver
in reverse. After that the right side came up .25". I'm guessing one
should measure ride height w/o turning the car in tight circles.

Any ride height tips?

Curt Nichols
 

I got the monster truck tires* mounted on the mudshark and dang if they
don't fill out those wheel wells, maybe a bit too much. Upon returning
from my "settle the suspension and give 'em a good heat cycle" drive, I
noticed a grandprixweiss scuff on the outer edge of one of the rear tires
(fantastic potholes here!). I can still fit my fingers between the rear
tires and fender without pinching them badly, but I'm thinking I need to
make sure the ride height is adjusted well.

So, I've armed myself with the factory specs, a handy tip page
() and a little knowledge (DANGER!). What
I'm still lacking is a handy tool for turning the nut to adjust the height
and any sage advice from those who have gone before me. (I've searched the
Rennlist archives for "ride height" and came up completely empty. This is,
of course, impossible.) Any tips in the "make it easier" category are
appreciated.

*Okay, they're not quite mudders, they're S-02 Pole Positions on 9/10x17"
Kinesis Supercups. But they DO fill out to the fender nicely. Only 70
miles on 'em so far.

Hey Calvin,

I think I can answer your query regarding drag racing.

The reason we're racing is because we are a bunch of mindless idiots that
are fanatical about our cars, believe them to be one of the finest and most
desirable automobiles on the road, like to test the limits of our sharks
and ourselves, and above all else, we like to hang out together and watch
each other do silly things. (Can I get an AMEN BROTHER?)

With regard to the half shaft issue, I've inserted an (edited) email
exchange between myself and DR which all of you might find of interest:



Hi Adam,

Darn you guys are going to have some fun, this looks so tempting to me it
might be worth flying out just to watch !!!!
....and I'd send you the airfare if I didn't think you'd get flamed on the
list for the next two months straight for taking a weekend off just to have
a life :).

Wally was nice enough to impart some comforting words of wisdom on a slight
mishap I had on my Nology wire install. Just to show my thanks for that
and for 928SP's ongoing support of my 928 habit, I'm going to be sending
y'all (trying my best southern accent here) a Pac NW Shark Drags T-shirt.
Since you folks won't be here for the event, I thought I'd send a piece of
the event out to you. They should be ready in the next couple weeks. I
figure with you getting the event shirts coupled with all of the orders to
replace broken half shafts after the event, it'll be just like you're here.

In truth I'm hoping for no mechanical failures, and will probably be giving
an "it's all about consistency, not quick e.t." speech prior to everyone
running. I'd feel really terrible of someone damaged their shark as a
result of the event.

So, can we get a bulk discount on those half shafts?

Discount heck, if anyone breaks theirs at your event I will sell them the
parts they need at my COST !!!
Now, now,..... I don't want to tell them that. Knowing these guys they'll
probably interpret that as an incentive to be breaking parts. :)

I kid you not when I talk about the competitiveness of these guys, they're
insane!

{End email}

........so, there you have it Calvin. The half shafts are covered :).

There are several different reasons for owning a shark, and I don't think
that one is more valid than the other. You can buy a low mileage show
piece and save it for sunny weekends, you can buy a high mileage mule and
run it through the paces (yours truly). Or you can do both with the same
car (Redinger, you kill me!)

I don't discount pride in ownership at all, for many having a shark in the
garage is the most satisfying part of ownership. (I'm not saying that this
is you, it's just an example).

For many of us locally here, pride in ownership is just a piece of the
pie, our intrigue goes into other areas like performance driving and
upgrades.

One of the reasons that I enjoy putting together these gatherings is that
there are so many local owners that share my philosophy of pushing these
cars deep into their performance envelope and trying different means to
extend that envelope.
Its kind of self serving, but I organize these Pac NW Gatherings because it
an opportunity for me to share ideas and stories with like minded
individuals.

I realize that many out there don't share the same philosophy regarding
their sharks, and prefer to preserve them and drive them occasionally. The
first local gathering, The 928 Owner's Showdown which was held last fall,
was tailored to allow all local owners to participate in an event (Kart
Race) regardless of everyone's personal philosophy about their own car, and
just share in our pride of ownership.
I wanted an event designed around getting people together without putting
any of the sharks at risk. Much to my suprise, I discovered a lot of
owners were interested in pushing their cars and discovering and improving
performance benefits much like myself. We did a dyno day next. I couldn't
believe the amount of willing participants that attended. As almost a
joke, I threw out the idea of bracket drags for the next event. I really
was hit with a sense of pride when there was an almost unanimous "when's
the date?" for a reply.

Breakage is costly, there's no doubt about it, but a lot of us accepted
that long before we purchased our sharks.

A lot of the crazy things we do with our sharks provides R&D opportunities
to help the 928 community as well. Louie is actively developing and
designing modifications for our cars, some of which I can proudly say he
tested at our last event. Ultimately, these performance items may end up
on your car. If you have a set of steroid drop links, than you already
have benefitted from someone else's high performance testing.

I hope this kind of explains things Calvin. I wouldn't fault any shark
owner for not wanting to race his car, I can see how it may be seen as
abusing the vehicle. For some of us though, part of ownership means
finding shortfalls in our cars and improving them.

So, are you going to come out and watch the carnage on the 25th? Someone
may need to ask you for a ride home if their shark goes home on a flatbed.

My 87 Auto has a 2.2 as does the 88. I think 89 and up got the

and the GT has a 2.75. Someone put in a 3.11 (Rennlist) but don't
know the cost or loss of top end. As with all things there are trade

in
the 1/4 mile events, just out there to have some fun. Personally I
think putting my 128000 miler on the dyno was a he## of a lot riskier
than running down the 1/4 mile. Shoot I do that every time I hit one
