What I'm talking about is getting the right chip, fuel/air mixures, timing and stuff like that.
Too much horsepower?

Hey, I just talked to the seller. He's going to send out the build sheet and dyno specs and pics and stuff. I'll share it with you guys when I get it because nobody knows like you guys know.
It has a Greenwood body kit installed which from what I've seen maybe a little overdone (yes it has a wing). I would be temped to make it look like the Blue/White C4 on the latest Ecklers cover. It's the coolest C4 I've ever seen.

But he says is it's running rich when he turned the supercharger down (I don't know how he does that), is that an issue with the chip? The fuel pump? The injectors? Do they make an adjustable devise that will regulate the fuel.
I'm really trying to understand all this.

I would agree if it were a more balanced car like a Chevelle or something, but the C4's are so lite in the back and it would be easy to loose control I would think.

My supercharged 383 is running 12psi of boost, and alcohol injection, and it gets 500 RWHP (about 600 crank horspower). I would love to see the build and dyno sheets for the car you are checking out - I am looking for an upgrade...

This is just a follow up. I went to see this insane 93 Vette and it was crazy what this guy did. A 388 with a blower and 16 injectors, 3 control/ignition modules, huge radiator etc, etc, all packed in under a stock hood.
There is a problem though...
That car is insainly LOUD!!!!! Just with the engine at idle, we had to yell at each other to talk. Even at idle, that thing is SCREAMING!! He said to forget about listening to the radio or anything like that inside the car. I asked him if it was the exhaust noise (It has a Corsa system that was pretty loud). He said you can't hear the exhaust, it's all under the hood and primarilly the blower.
That car would be sooooo much fun but it's not worth going deaf over.
If you guys know how to quiet the thing down let me know, otherwise the search continues.

Perhaps I am wrong as I haven't seen everything, now after posting that I will call complete and total bull**** on this one. The blower will make some noise sure but it's probably the longtube headers and hi-flow cats or lack of cats all together that are making it LOUD.

I agree but I have never heard a Vortech or Paxton or GMC blower for that matter make a ridiculous amount of noise. It's probably a combination of things making it stupid loud which could easily be corrected. Now that's I've posted that I will undoubtedly be proven wrong

Why, why...Dude, I would seriously consider just getting something stock. The fastest stock vette of any generation that you can afford. If it aint fast enough, take it to someone you trust and put some NOS on it.
Though it is admirable that you look to this forum before purchasing a modded Vette, it is very difficult for forum members to know whats in this machine. No dyno sheets, no engine specs. And even if the guy give you the specs, can you trust whats on the paper. Even the dyno sheet may be from a different car.
Save yourself from this nightmare. it's tough enough for folk with a lot of engine saavy to figure out what someone else did.

This thread brings to mind the member who bought a C4 about and was convinced by the seller it had a 383 in it. Soon as the numbers were posted it was obvious he got ripped off; after further investigation it was confirmed.
Think he tried to sell it fairly quick...Sad, he was so thrilled to have gotten it.
I have no problem buying a modded car but it would have to be from someone I know, know of at least, not a stranger for sure.
Just know that most people selling a modded car (not referring to here) either;
1- Are completely full of chit
2- Have no idea what they are talking about
Or a little bit of both.
Buyer beware

I purchased forum member "Bruce" 93 vette. See second car in signature. Anyways, with a supercharger and 15lbs boost he made 592rwhp on the 383. He latter converted it to a 85mm rear mount turbo, but never quite finished the project. He was shooting for 1,000 rwhp at 25lbs boost.
I have never got it running yet, due to other obligations going on now, but I dont plan to try to push it that hard. I dont believe a factory motor would last long doing that.
If he is running the stock computer, plan on changing it to a DFI, or something else. The 92-93 are hard to tune with boost and espically the kind of power you are talking.
Good luck, and could you share more details about the car, such as what blower, 6sp or auto, etc?
