i take it you are still waging your anti-turbo war
sure on a huge motor with a "screwed" blower (as you call it) there is going to be a lot of horsepower available
like i said b4, a turbo by nature will always develop more horsepower versus a supercharger on the same motor.
a supercharger's maximum efficiency is about 50% (and thats a "perfect" number)
while a turbo operates on average around 70%, (where as 100% would be its "perfect" number)
unfortunately for the supercharger, it uses some of its own energy to power itself, so therefore it is very inefficient compared to a turbo.
its retarded that you think a 9.08 @ 157MPH in a stock chassis car with interior, street tires and a 2.0 liter turbo is a shitty time compared to your "screwed blower".
how much more displacement are these friends of yours using?

I didn't say that I was "anti" turbo and I agree that they can produce more power.......but at high RPM's. There are pro's and con's with both systems. The thing that makes surpercharging popular is the fact that it compliments powerful NA enines by producing power instantly since it is connected to the drive system - although that does rob power. HOWEVER on large V8 motors that parasitic drag is tollerable. Turbo does have lag but can produce more power in the end. People say thay also produce more heat - but again big deal, I've never heard of that being a problem. The other thing is that if you have an engine failure and the motor shuts down while you're under heavy acceleration and the turbo is spinning, the unit can be damaged.
I don't know how familiar you are with superchargers. There are different types of superchargers, the old roots style (which are more inefficient) that run with twin rotors, and the newer centrifugal type superchargers which run with an impeller. The later are capable of running higher RPM's and are more efficient but the roots type can provide more low end rpm assistance. If you are into racing, the name of the game is "bite" off of the corner. The roots type blower will give that bite and allow you to get off the corner and onto the straightaway with good speed. The turbo unit would lag under acceleration but catch up at the end of the straightaway with it's top end potential. So at the end of the day you can spend more for a turbo while achieving the same result. That is really the reason I guess turbo has not made a huge impact on North American V8 cars - at least not yet.
My point with the NA engines is this: If you're going to produce race engines, you would take a base engine that is "basic" and has potential to soup up to sell to race customers and hot-rod customers. Take the WRX engine and 350Z........which one is likely to have more aftermarket potential? Correct me if I'm wrong but how much more can you do to the WRX engine besides beef up the pistons, rods and add a larger turbo unit? With the 350Z there is more room for work such as displacement and supercharging to compliment it's already great bottom end performance.
I don't think that 9.08 isn't respectable, especially for 2.0 litres. The fastest 4cyl I have seen was a Civic up this way that ran in the 10's which is impressive in itself..... but they are not all that common.

You can do just as much to the WRX as you can a 350z minus the two extra pistons and rods. It's got camshafts, valvetrain, intake manifold, etc... just like the 350z.

and also...the wrx has the same, if not more potential, than the 350z...it is, afterall, awd. now, at the track it might not make too much of a difference, but in just about any street situation, it would. the story that i like and keep telling is my friend with the 11 second lightening getting destroyed by an sti in a street race. the lightening just couldn't hook up, and spun through 2-1/2 gears. by that time, the race was almost over and the subaru was 3-4 cars ahead.
there is also tons of aftermarket support for subaru, including turbo upgrades, stroker kits, pistons/rods, ecu....you name it.
but, if we are having a pissing contest about aftermarket support...no car has more than civics from the 90's.
