On the way home from school a friend of mine with a bolt-on '00 GT caught a light with another guy I know that has a supposedly cammed '98 Z28. The GT is an auto with 4.10's, 2800 stall converter, CAI, full exhaust with LT's and was tuned by a local shop. The Z28 is also an auto and has a lid, slighly looser converter, cut-out, stock 2.73's and a cam. I was behind them in the RS. They went on green, the Z28 spun and fishtailed all over the place, the GT spun too but kept it straight and pulled about car. They let off at about 90 mph with GT keeping the lead. Next was from a 40 mph roll. Both hit and stayed dead even till about 110 mph with Z28 pulling just slightly.

I don't know what cam the Z has but he says its pretty small. The car has no tuning at all. It idles really rough so it sounds cammed but I thought he would do a lot better than that. Either he's lying about the cam or that's the worst running LS1 in Houston! The GT is a low 13 sec car and traps around 104 mph. I've raced and beaten the GT so I think I'm going to see if I can get a piece of that Z28!

 

I think I'd blame it on the bad tune and bad driver in the Z28...no way he should've lost to that Mustang.

 

When my 2000 Z28 was STOCK I ran very consistant 13.2's at 106 mph. No way in hell he should have lost if the stang is only trapping 104 mph.

 

I have to agree with the Camaro running bad or maybe driver error (even though it was a roll the 2nd time). Could it have possibly been a 97 LT1 instead, cause a cammed LT1 would trap about 104 or so? Just thinking out loud!

 

Cammed LT1's do a little better than that. My stock 96 WS6 ran 104. After the bolt ons and HOT cam, it ran 111.

Anything can happen on the street. Slow cars can take fast cars pretty easily. Take it to the track and I'm sure would have been a different story.

 

Absolutely an LS1, give me a little credit there 25th! I talked to the guy and looked at the car up and down.

Like I said either the guy is lying about the cam or the car is just running that horrible. I get the feeling he's lying, just seems like that type of guy. He claimed he ran 12.7 at 111. If he was making that much power he should've walked away, especially from a roll.

 

I wasn't calling you a liar. I believe you. I don't believe the guy in the camaro though. A cammed LS1 can easily trap at over 115 mph with bolt ons and there have been several running 11's. If he has the mods he says he does he should have raped that stang unless he can't drive. So one of 3 things could be possible. 1, he can;t drive for ****, 2, he is lying and has no mods and is running like crap, or 3 he isnt lying, and his car is running like crap, and he can't drive, lol. If it's one thing ive learned from racing is never trust people. They simply lie, lol.

 

Woops, should've specified! I meant 25thmustang not 25THRSS.

There is another possibility, my buddy with the GT did something else to his car and didn't tell me. I don't think so though. I would've seen his tail lights by now!

 

oops, forgot that one too. Maybe a little shot of nitrous?

 

Maybe near you but near me a bone stock LT1 will pull 96-99, and with nothing but a cam shoud pull a 104 trap. My friend has a 94 LT1 with all the bolt-ons roller rockers, and a built auto. He only traps 98-99!

I wasnt figuring you messed up on the years, I just thought maybe for some weird chance you just saw the back of the car you thought it was an LS1 and it really was an LT1. Remember I doubt the auto GT could run with a cammed LS1 either!

 

That's pretty sad. I think mine was a good one I went 13.50@103.9 the only time out with 3.42 gears. I put 4.10 gears in and ran 13.18@104.9. Still on stock everything. Then the cam, headers, rockers, cat-back, Nittos, LT1 Edit, etc. it ran 12.44@111.27.

I have seen some dog LT1's though. So anything is possible.

 

Almost fell out of my chair!!... untill I read this...


modded LS1's from a roll = no chance unless your packin a big blower, a V-10 or greater.

 

Well the last race day there was an LT1 Formula (black, with yellow rims) running 14.5s at 96 all day. It was an auto with a decent launch! My friends 94 was in the 14s at 96 or so stock also! I am not doubting your times, and I believe elevation and other variables apply, but from my experience a cammed LT1 should see 104-105 with no other mods!

 

Where are you guys that LS1s run mid-low 13s stock?

I was at New York International Raceway Park the other Friday night on a hot and humid day and saw 5 LS1s there, all with exhausts but I'm not sure what other mods. I must have seen about 15 runs of them and the quickest was 13.9, most of the runs were in the 14.1-14.2 range. Lowest mph I saw was 99 and highest 102 or so, so maybe they were spinning. Makes my 14.3@96.5 look better!

You said it yourself, the Z28 spun bad...I've seen a heavily modded LS-1 that dialed in at 13.2 run a 14.5 cuase of spinning...traction will make or break you.

 

I see stock LS1's turning low 13's all the time back at RCR. I've also seen the LS1 that couldn't break out of the 14's too, sucks to be that guy but whaterver.

The excessive spinning only accounts for the run from a dead stop obviously. From a roll Z28 couldn't pull away until around 110 mph. Even then he only pulled like half a fender.

 

Come on down to Etown!! ill show you 6 cyls that run thoes times w/o nitrous!! Mid to low 13's to high 12's is about the range... anything higher then 13.8... you need to learn how to drive or get a different car... its just that simple. I can see on a humid day the cars sucked, but not that bad. Search LS1.com and LS1tech.com and you will find plenty of stock or near stock cars running the low 13's to upper 12's with very little work done.

 

I don't have to see anything or go by rumors either. I drove my STOCK 2000 Z28 to several very consistant 13.2's at 106 mph myself so yes they can and will do it. This was on a crappy 2.1 60 because I couldn't hook on snow tires.

 

I seriously want to meet up with you sometime to check that beast out

 

lol, yeah, me too. Only thing is the "beast" aint runnin right now. Kinda hard when you only have half of your top end on, lol. Hopefully when I get enough time I can finish this thing finally!
