kept up with LT1 Trans-Am

Was following a friend of mine in a 96 trans am and he wanted to do a run from 50. So, i put it in third and we went. to my amazement, i kept up. on top of that, i was feathering the throttle to keep my boost down. he has intake, exhaust cutout after the cat, and a tuned ECU, also 3.23 gears. my mods are in sig.

at interstate speeds, my boost can reach upwards of 20psi momentarily. i still have the stock injectors but 850's are on the way.

The times in your sig are umm...

So you got a street port and boost WAY too much and you only took off 2 tenths of a sec in the 1/4 mile?

Are you sure you won any races? I dont want to flame you.. but stock time is less than you are running.

Are you launching like a ricer at 7k or what?

I raced a 2001 SS (don't those have LS1's in them) with exhaust and intake and beat the crap out of him at 6 PSI...

Of course I also have a modded 90 FC.

OK, well, my 60' on the stock run was 2.3ish, and the modded launch was 2.6ish. also, my extra thottle plates weren't opening all the way which really sucked *** and killed power. i didn't have exhaust then either. only streetport and intake.

now...with the exhaust that is in my sig. i can spin tires in second rolling into boost, dry road.

also, ya, 20psi is scary i know, i bout **** my pants the first time i noticed it. motor still runs fine and i try to keep it below 18. i'll try to get a vid next time.

LS1's came in 98+ Z's and TA's and came with 305hp. The SS and WS6 packaged models had 320hp. LT1's came with 275(93-95)/285(96-97) depending on single or dual cat exhaust. This guy was probably pushing 310 with the intake, tuning and cutout. He was impressed to say the least. All I have to do is ask and he'll race me again. Only this time on tape. I currently suck at launching so we'll try to keep it from a roll.

Dude are you sure you are running 20psi? How are you acheiving this? I only see a gutted precat and intake. Does this mean you still have the stock cat?

Also the stock IC is no where close to efficiency levels at above 15psi and the turbo will start spinning itself to death and produces probably more heat than power.

LOL Are you sure about that? Not to flame you or anything... but if you can handle Z28s, stock SS cars shouldn't be a problem for you.

Just an FYI for people who probably don't know or care about the F-body lineup (now extinct):

The SS and the Z28 have the same engine, and basically the same power. The ONLY difference in the 2 is the SS gets a ram-air hood and a slightly different exhaust. On a dyno, the difference is usually less than 5-10 HP. I've seen many dynos from both cars, as I used to be a very active member in the local F-body club, and still own an 86 Z28 (very much not stock). It should be sold by the end of the week though (more money for my TII hehehe). At most of our dyno days, the guys who were stock were putting out around 310ish HP to the wheels, and slightly higher than that TQ to the wheels (for the manual tranny models).

The reason the Z28 was rated as being lower was basically so GM could sell more SS cars, which had about a 5,000 dollar markup for what ammounted to a hood, stickers, and a little different exhaust. If you visit and Camaro boards, there's usually some pretty big pissing contests between Z28 owners who wish they had an SS, and SS owners pissed that they paid an extra 5,000 for a car that basically performs the same as the Z28

those aren't the only differences. the ss and ws6 suspension packages are better than the z28/ta suspension.

sounds like someones boost guage is broken. 20psi. You could get 20psi on a stock turbo even if you ran nothing but a down pipe. Not to mention on stock fuel?

where is the video? I think 15 psi is already pushing it on stock injectors and turbo.

My mother has an LT1 Camaro and I beat her many times, although I am not sure what kind of boost I was hitting. All my car had at the time was a lower compression engine (about 80psi) Racing beat turbo back exhaust and FCD.... I also spanked a LT1 vette. They both got me off the line because of the torque, but once I got into 2nd and 3rd I walked right by them.

Once I get my car back together, I am going to go after my managers Viper, but I doubt I will beat him, I am sure i can give him a good run....

yeah but the SS I raced had exhaust and intake)not sure if that makes a big difference on domestics.....
No exhaust and intake add VERY LITTLE performance, it is more just for the sound. GM did a very good job at handling those to areas. Swap an intake manifold or a cam then we are talking some perforamce, besides the rated HP numbers low, they only state those because they do not want to **** off the vette owners who pay the extra $10K for 15-30 more hp....
