13.6@101 in a 2.73 geared auto Vert? That's unheard of. What was the DA?

No "chip" in '95 and 110 traps with those mods and no weight removed, stock gears, stock rockers/pulley/water pump doesn't sound right. Also, how did you get the LT4 intake to fit the stock heads? The runners don't line up and will actually hurt more than help.

DA was probably -400' on the 13.51 trip... I actually drove the car that night. Not sure on the other trips as my buddy often took the car on his own. I did see the slips though. They were all usually winter/early spring in Houston so DA was always pretty good. We did ice the intake down had the fuel at 1/4 tank. That night my buddy went a 13.60, then I drove it and went a .59 then a .51... all were at 103 mph. Letting the car shift itsself and launching from about 1500 rpms... Nothing to it..

Here was the car around the time we took it to the track, i think this was the weekend before, right after we put the axle back kit on..



All stock, other then the axle back and K&N filter. 49k miles


The converter/LTs/mid pipes/intake/TB/MTI tune all came in the next year or so after..

Yeah I wasnt sure if it was still a chip on those models or if they were flashing ECUs on those. I believe it was something from MTI though.. As for the LT4 intake, I am not sure, I believe he just bolted it on, wouldnt suprise me if he didnt notice the runner issue...LOL... I know it was a red intake with a billet TB though.

My buddy passed away back in 2011, I bought his silver Z06 from his wife and I helped her sell off his other cars...The 95' was actually his wife's. We had a great friendship and played with cars for 20 years together..

That's a nice looking vette. Looks VERY well maintained!

Sorry to hear that man. Sounds like he had a blast tho and kept great friends around.

Hmmm I might have to get one of those. I'm just going to concentrate on getting the headers setup perfect before I really consider a cam. It can wait until next winter.

Wow those are some impressive times.... I've never been to the track yet, but I'm going up to NE Dragway this spring. I'm not expecting much on street tires though.

I've always thought about leaving it alone haha, I'm definitely doing headers but I'm still on the fence with a lot of other things.... it is always funny to beat newer cars with an old stock Corvette

ajrothm

Yes it is!

I have another buddy with a 91' ZR1, its all stock other then a Corsa cat back... That car runs suprisingly strong... We tried to run it at the strip once on the original tires (car only has 19k miles) and it spun most of the way thru 1st so the ET sucked...it was like a 13.80@110. We only made 3 passes because it just wasnt safe to run it on those tires it spun so bad...

After he got some fresh Good Years on it, we have played around with quite a few cars on the street and it really held its own.. Hell I raced him in my cam only 99 Trans Am from a 20 mph roll and only beat him by about 2-3 car lengths (My car ran 12.60s@113 on DRs)....Those Zr1s from a 50 mph roll are pretty strong...right in their power band. Its cool beating C5s/C6s with it from a roll....they all think it has stuff dont to it but it doesnt...


I actually am kind of jonesing for a 90' ZR1 myself...

I wouldn't be so sure! I sent out my alcohol pump to be rebuilt. Not sure when it will be back. I will only be running like 18lbs of boost until that comes back in. This might be the factor that evens us out .

burning a chip isn't that bad, I had 3 different chips I carried around with me in my turbo T.

92Vette

Don't even get me started with ZR-1's.... you have no idea how badly I want one!! I've been all over the ZR-1 forum trying to gather info about the car, what an impressive machine they are. I hope to get one when out of college, good luck finding one yourself, they're rare!



Hmmmm now this is getting interesting..... if there is some nice weather on a weekend we might have to line something up. I'll at least see you on the Vermont cruise in the spring.

Thanks! It's not too bad for 115k miles Just ordered Exotic Muscle longtubes too!

Is it easy to just swap chips? I might end up doing the same thing haha

Bump for more views!

Must be the Opti.Good job.

Good runs. What was the roll speed vs the M3? Do you know what gear he started in?

92Vette

The roll was from around 50 I think, I started in second and really got the jump on him. Maybe that's a bad roll speed for M3's? Idk. He said he wasn't ready, even though I waited for him to go first before I punched it

I'm really surprised he didn't beat me with the 33 extra horsepower, plus I had a passenger and a full tank. We'll probably race again pretty soon.

Atta guy!

You'd love the gains on an LT1 in both sound and feel with some longtubes, off road midpipes, and catback.

Tracked350Z

50 is a perfect spot for the M3. Just past peak torque and the hp is climbing very quickly. He will be starting around 66-6700 rpm. Make sure he starts in 2nd. He should get the jump on you and he should pull. I wonder how many miles are on his M3.

92Vette

I think headers are good for a first mod, especially because I might get a cam sometime. Hopefully I'll get 10-15 rwhp too!

No idea on how many miles, but now that you mention it, I think he said he started in the wrong gear... I'll be sure that he starts in second next time. Trust me, I was baffled that I won too!

Nice on the headers. You have a way of passing inspection without cats? Maybe a method of tuning the cats off, or are you planning on running with high flow cats on?

Hopefully you can rock a CAI and maybe some goodies like that too. I'm not really familiar with intake options on C4s

92Vette

I don't have to pass emissions in Mass, my car is too old

There's really nothing you can do intake wise besides cut the lid (which I'm doing as soon as I get the chance). The air filter is HUGE on this car, the stock intake flows pretty well. I've been on the fence for a while about what I want to do next:

1. GM hotcam w/ 1.6 roller rockers and a bunch of new OEM parts
2. 1.7 roller rockers, with dual springs, guideplates, and hardened pushrods
3. Nothing.
4. Maybe try some weight reduction

But I need money first

Nice! I'd definitely do it when you have the exhaust setup and do the LT4 Hotcam and all of that fun jazz or LE 224/230 cam or AI's 220/230 cam (comparable to LT4 hotcam with potentially more power)
