Snipe ole buddy, you are just plain wrong! I can hook up my GT just fine... when I want to :-).

Once again you take to personal vitriol because you cannot specifically refute my posts.
This is not the first time you have been warned about taking off-topic assumptions and interjecting it into a proper argument of boosted 928s. Why?

You want to know how much potential resides with the turbo, just look at Porsche's racing history. 962, 935, 917, etc. Did any successful racing Porsche ever use a belt driven compressor?
Did you even read what I said, or did you just see "unrequited", "crap", and "john" in the same post and start typing?

Hmmm, turbo vs SC...
Where is the only place in motorsports that you see a supercharger more than turbo.. Drag racing- they put a 200lb penalty on turbo cars? why?, aren't they soooo laggy?
Reliability, turbo has it, sorry. The unreliable turbos are just poorly planned out.
Heat, where's all this heat being pumped into the motor? The heat is a biproduct of compressing air, very little mechanical heat is added to it. You'll have the added heat from any forced induction, that's what intercooling is for.
A supercharger is very responsive to crank speed, a turbo is very responsive to engine load. That said in real world situations, a turbo would preform better, also, under dyno conditions normally a SC will preform better(it only needs crank speed to pull boost). Alot of dynos cannot fully or properly load a car to show full potential of a load dependent system(turbo).
It's been said, and it's true, tuning is the most important part of building a successful setup and having it last.
Attention to detail is a must!
I've witnessed a 944 turbo that put 380hp to the ground through stock 2" intercooler lines on a stock longblock. While everyone keeps saying that the stock IC lines have to go, too small, too many bends, never make any power with them, etc. It was done with a turbo, tuning and a set of injectors. Funny thing was, they never pushed it past 4K, it was developing a misfire up in the revs(ended up being a bad plug wire). Still layed down the numbers!
It's hard to explain everything, there's alot to turbo and suprecharger systems. Turbo is best in my book.

Brendan, I'm not going to waste time responding to your once again immature comments. I will say your response was somewhat Lag-like though. Bring what you have to the surface next year, or better yet show it now on here.
This was a post about CS vs Turbo torque curves. Andy's comments are spot on, so read up.

m21sniper,
Just because you can do something, doesn't mean that you must. I would rather have an ability, and learn how to best harness that ability, than to not have an ability at all.
