I don't think the body lends itself to highspeed past 145 or so. Mario Andretti didn't like it at high speed. I think if you wanted to push it farther cheaply you would want to start with the sr3 tubular chassis with later model steering. With todays technology you would be better off buying a z06 right off the show room floor for list price. You would spend way less and go alot faster in better comfort. Personally I would not push mine past 100 mph as it is an old car which has never been totally apart to rebuild. I have gotten conservative in my old age and don't heal up as fast as I used to and I realize now that I'm not invincible.

Mine too, but it is not a fair comparison. Norval has done a ton of great work on his C-3, but he was stuck with the C-3 platform when he started. The Z06 platform is a far superior car in every aspect over the C-3. I am not sure if a team of race car engineers could get a C-3 on par with a Z06.....that being said I'll bet Norval would run away from the Z in a 50-150 mph charge; no doubt all that Z06 would see is Norval's tail lights getting smaller.

The better bet would be let Norval start from the ground up on a car with about 250,000 grand to throw at it, sorta like Merlin, who I agree with his "I am rich, so I am smarter than you" attitude cost him a lot of money and ultimately doomed his project.

Now, there is the car Twin Turbo is building. That car was built from the ground up to be an auto X type car. He may have something for a Z06.

I don't expect to end up with the performance of the hyper-priced vehicles mentioned above, but I intend to at least make them work for their bragging rights. I'm making progress on my C4 suspension transplant, with Wilwoods all around, and front coilovers. I estimate I've taken an easy hundred pounds of suspension weight off the car, along with getting some improved geometry versus the original C3 stuff. This summer's project is to also take the guts out of my current aluminum head 427 (the original engine is stored away) and stuff it into a ZL1 block. It won't be the most hi tech vehicle on the street or track(I don't have the time or money for that), but I've been able to post more interesting pictures on the forum than just a cancelled check to the dealer.
Just my two cents.

Then again there are bux down enthusiastic hotrodders like me....who do their own work within limitations and call it a day....which fills the description for what?? 95% of the guys on this forum??

some are more jaded, other noobs....

but there is not one section or parameter of my car that is stock, not one, not anymore....and getting worse every damn day....frustrating, for sure, FUN, nuttin like it!!!!.....agravating?? you betcha.....

blast to drive?? hell yes....everyone from a little kid on a bike to grandpa behind his own vert, smiles and shouts around here, anyway....

in Wash DC I was considered an oddball.....hell with them boring *** wholes....

i find it perplexing that updated suspension is cheating but you are considering an LSx engine
now, let me drag out my soapbox...
you're pizzin' in the wind until you stiffen up the frame. period. exclamation point!

Took mine up to 110 last night. Backed off when I realized how fast I was going.

mrvette

It don't matter how fast you going IF you got speed rated tires, the car has lost more ***** than I do.....with the top and windows down....

in a coupe with tops and windows up....that's an unfair comparison....

turtlevette

tires are the #1 most important thing.

unless you can get modern wide tires on the C3, all the suspension upgrades in the world won't do it.

TT is going to run 425 wide tires which is the right idea to get a lot more rubber down than the newer cars. A C3 on really wide race rubber might have a chance of outhandling a C6 Zo6 on stock street tires.

I don't worry about nice to have things like zero bumpsteer. The driver can compensate for the handling quirks that the C3 exhibits. It takes lots of practice and the right touch. An instructor drove me around in my car and it scared the shiit out of him.

I think TT is trying to build a Ferrari in Corvette clothing...

Wonder if I can take the shaft out of this and fit it into a C3ball joint.

I was wanting to put a modern suspension under my 79 and for the money I was going to spend for suspension parts, I got a 92 LT1 instead. It has satisfied my cravings for a while!

The only thing I have not seen discussed which you can't update is the aerodynamics. C3s have very poor aerodynamics compared to C6s.

Thats what threw me about the Bugatti Verion...it needs only 253 horsepower to reach 150 mph! That is awesome when you think about it. An average C3 might need 380-400hp to make that speed, and a prepared one 300 or so. The Bug needs the next 760 hp to go 100 mph faster, or 250 mph at 1000 hp. A comparable C-3??? The greenwood cars went very fast, but were racing machines. If you want an F50, just buy one.

Regarding the 911 and its improvment in racing as the 934/935 F. Porsche once said "You cannot make a racehorse out of a pig....but you can make a very fast pig..."

Pigs....

You can tweak the C3 aerodynamics a bit, but is that really that big a deal? Most of the tracks I've had the opportunity to run on are more geared towards handling, rather than pure top end. I rarely got over 140 on those tracks (and the car felt fine), and 120 is more common. I'm more concerned about trying to keep up with the modern cars in 40 to 80 mph corners than the rare 180 mph straights.

If your just compairing to a front engine design like a modern
C/6 they are light for all the accesories they have and the frame
is torsionally stiff and great suspension compaired to a C/3.
If you have a silly putty frame to work the suspension off its like
having a million dollar house with no foundation under it. only way I
can see to make a C/3 handel with modern vette is to
get the weight down way under the 3050 of a modern vette
use a stiff tubular frame with a full roll cage for more strength
use at least a C/4 suspension in the back use an all aluminum small block maybe take some weight out of the fiberglass use some
carbon fiber to reinforce your thined out glass. Weight is death
for handling,acelleration,braking, if you could get a C/3 down to
2500 pounds giving it a big weight advantage use a strong frame
big brakes, better suspension, bigger brakes and of course better
tires with a 500 pound weight advantage you could put the hurt
on a modern vette. Trying to make one handel with a modern
mid engine performace car that would be tough.

Savitske sells Howe modular extended ball joints, they're expensive though. You can order them in 2 sizes. I told you know who w/ the black 69 and the viper where to get them and i think he has them

turtlevette

Using these ball joint will prevent going to a 5" or greater backspace. I don't think its worth it.

Just dial in a ton of negative camber when you get to the track.

Twin_Turbo

why would you need more than 4.5"backspace? are you trying to increase the scrub radius and increse the bearing load during cornering (since we're talking about the track) ???
