Definitely a noticable SOTP difference, the car has slowed down. So, this being the same exact car with different body parts, I'd have to say Formulas are indeed quicker than Trans Ams. The T/A bumper and hatch were alot heavier than the Formula parts! And I still don't even have all the T/A parts on yet, I will continue to weight it down further. I know where you read that and that website is bogus, if the guy got a quicker time from the T/A it must be because the T/A's engine runs stronger than the Formula's engine in that particular case, every car is different. But, like Nine Ball said, it's simple physics... if you race two identical cars but one is lighter, the lighter car will be quicker. The only reason I'm doing the conversion is because I like the way Trans Ams look better than the Formulas, even though I'm putting extra weight on my car by doing this.

as far as the hole t/a package id say weighs maybe 100to 150 pounds more than the formula. yet its more areodynamic so i would not say one is faster than the other or because they are the same car and will perform the same look at camaros the look way diffrent yet they perform the same. cars bein faster are on a case by case scerario not a brass gerneralization

T/A is typically ~100 lbs heavier than a Formula. Even the rear hatch shocks are different part #'s since the T/A hatch is heavier. Don't forget the side skirts, lower hanging rear bumper, etc....
T/As are not more aerodynamic than Formulas either, it is purely cosmetics.
SS/WS6 aren't any quicker than the base model cars, the 17" wheels actually make you run a little slower than the stock 16s. The quickest factory LS1 f-bodies are the no-option base model Z28 hardtops.

Wow. I did not know that. So what the hell is the point of it? Fake marketing? HOw does the WS-6 supposedly get higher power ratings? And is there any advantage of the WS-6?
Also on a side note. I bought a WS-6 style "functional" ram air hood. Does that mean my hood is actually better than the real thing?

How strange, considering the only other major inlet of air is under the front bumper. The ram air dump is much more direct to the filter/intake. Granted it's not actual direct ram air, but it has to provide a better air source than disturbed underbody air. This has to keep the engine compartment slightly more pressurised (but maybe not enough to make a performance difference). Is this backed up by actual track data with both options installed on the same car, or is it a bunch of BS like this particular thread is full of? Doesn't matter the actual answer though...the hood looks kick ***!

Both Pontiac and Chevrolet both said the increase in power was more from allowing the engine bay to clear hot underhood temps.
In 01 the LS1 Formula was rated at 310, the WS6 was 325. They both dyno the same and the 15hp increase is barely noticeable when at speeds due to the weight difference.
The one area I do disagree is on the weight side. The TA came stock with T-tops, Leather, and the whole ground effects kit.
The guy I raced said his WS6 weighed in right at 3680 pounds, my Formula is right at 3440 pounds. If the hatch is 38 pounds more I can only think the t-tops weight more than the plastic roof, the leather and power seats weigh more than the cloth Formula interior, and then the rest of the ground effects kit.
Lets say 150 pounds though, that is almost .15 tenths in the 1/4. Plus I read somewhere that the Formula had a Cd of .31 and the WS6 TA had a Cd of .34. This was because of the larger frontal area on teh WS6 cars due to the higher hood height.
There are alot of variables that can affect the outcome of a race between these two cars.

Are you a former import owner or what? Stability at 75 mph is pretty silly, your car would be just as stable without a hatch at all, maybe even no hood either....at 75 mph.
Talk 175 mph and we'll pay more attention.
BTW, the faster f-body drag racers typically get rid of their T/A wing and go with more low profile Formula or sheetmetal wings for a reason. It isn't because the T/A wing works better.
