PT vette

[dusterbd13]

i figured that this is kind of pro-touring (well, in the extreme at least). started out as a stock 88 vette that we picked up from a guy in raleigh for 5000. fixed what was broke at first, and started tracking it with the stock brakes, stock motor, and that horrible 4+3 tranny. we rebuilt the suspeinsion with bilstein shocks and poly bushings, added C5 front brakes, and headers/exhaust/miniram intake. raced for another season until we spun a bearing. then built a STOUT 383, swapped in a ZF six speed, added a four point bar, and ran it some more. wound up cavitating the oil pump due to cornering loads and eating another couple of bearings. so the motor came out again. as well as the interior. and everything not needed for NASA time trials and DE.
the current version, after two motors, two dry sump setups, etc, is:
dry sump 383 stroker, TPI based mini-ram induction, full exhaust. made around 430 WHP at 100% duty cycle on the injectors. currently adding bigger injectors.
full aluminum interior, all ultralight gauges with standalone warning lights, kirkey seats, coolsuit, and data acquisition system.
Z51 springs, VB&P offset bushings, custom uppre control arm spacers, Z51 sway bars, revalved bilstein shocks, Kumho slicks
C5 front brakes with cooling ducts, wilwood H pads, stainless lines
Kawasaki green paint, ZR1 wheels. Chassis bracing, motor plate, custom wiring harness (retaining power mirrors and ABS!).

dont know how pro touring this is, but i thought id share what i'd built. and the cool thing is, my father is the one that drives it. hes turning 64 this year. and now he wants to buld a northstar powered Locost...

these are before/still street car pictures





and now, full on track car:

That sounds like a pretty mean Corvette... I often wonder if I should convert to a dry sump oil system considering how hard I take the turns... I haven't killed any of my other cars yet but knock on wood I suppose... I wouldn't know where to begin though... any pointers???

& I'd say that Corvette is probably beyond your typical pro-touring classification, more of a Street Fighter!

& You'll have to excuse my lack of posting on this site... I live on NastyZ and pretty much browse around on here...

sounds like you two are having a ton of fun with it!! keep it up!!

[dafabricata]

DAMN!!! That thing looks like a LOT of fun!!!

[4birdman]

I remember that thing from AutoFair. Very sweet ride! :D

[bbcc]

Wow. I've spent many hours in class thinking of building a road race c4. Very cool.

Oh, and what happened to the number one cylinder? Looks like it went ridiclously lean or some oil cought fire on the outside of the tube.

cheers bbcc

first question:
i would not recomend you go dry sump unless its absolutely necessary. tearing down the block to do the required modifications/machining is the cheapest/easiest part o the conversion. you dont even want to know how much we have in it.

as far as the #1 cyl, it didnt burn. we actually had to cut and rewelt that section of the header to clear the dry sump pump. we never recoated it, hence the reason its ugly.

hope this helps.
any other questions?

Looks good to me Michael but then again building Corvettes is what I do and I'm in the middle of building an 87 C4. It will be a street car though. 5.3 liter Gen 3 and TKO 600. Lots of other fun parts in there as well. C4 vettes are my favorite generation, especially the later design.

Why are the tires mounted in the wrong direction,never seen that before.

I love the front brake venting...

So the questions I have,
1) What is the remote for?
2) If you had to build it all over again, what would you do different?
3) If you had to build it all over again, what would you do the same?

Nice work btw...

[dusterbd13]

1) remote is for the camcorder. we tape events to evaluate driver performance
2) this one is hard. part of me says don't paint it, leave the interior and lights in it. very brutal street car. the other part of me says that we should have started from the beginning and made it a dedicated track car, doing a full cage, better formed dash, and more structural bracing. iknow either way i would do the wiring completely different, go with coil-overs if they werent so expensive, and find a way to get more weight out of it. also would not have used the fabricator we did on the first dry sump setup. he was an absolute mistake.
3) same motor, dry sump, and the chassis/brake upgrades. id also definately keep the analog gauges over the factory digital stuff, and the stand alone warning lights. i also love the roll bar that we used.

i'm sorry it took me so long to answer, but this one was tough. lot of thought on it.

I bet it's simply because those are the street tires for moving the car around. Don't want to risk damaging the race slicks away from the track.

[dusterbd13]

exactly. sorry, i forgot to answer that question. theyre just rollers, never driven on (unless its to break something in an the roads around the shop.
