Yup..Id agree....this is chevy high performance...not chevy v8 high performance.

Although I am quite partial to the torque curves of my v8's..I still like the revability with reliability and economics of my 4 cylinders and as far as I am concerned...the imports are wining the 4 cylinder war...so lets bring it back home and crank out a few hundred ponies from one of those eco-tec deals....hehe

Somthing like...new drive ratios on the blower and a sheet metal intake...sweet..perhaps even a few thousand rpms more than were used to...like 9k...yeah.

The S2000 Honda sports car makes all of it's 240 hp above 7000 rpm and it really Kicks.
 
My roomate used to have a Toyota Matrix SRX that redlined at 8200 rpm. It was definatly a motion sickness mobile. It made 180 hp and 130 ft/lbs somewhere in there. The torque curve did not hit untill 6000 rpm. Saying that the S2000 really kicks above 7000 rpm is all fine and dandy, but the car is dog below that point. The matrix was fun above 6000 and it pulled really hard, but there was really only a span in 1st and 2nd gear of 20-30 mph each where he could actually use the power, then it dropped back down to like 4000 and was completly ball-less. Now if CHP could do an eco-tech build that applied power low in the rpm range and still revved high then i'd be all for it. But if it would be a power band from 6000-9000 rpm's I say no thank you.

True, but the VTEC Honda engine was designed to help with the lack of low-end torque. The S2000's torque curve is definately in the upper RPM range, but the vehicle is very light. However, as I've heard it called, it's "still more of a science project than a car." I'd agree. The engine is advanced but it still has to climb through several thousand RPM to get anywhere. Thank god for manual transmissions.

I'm doubting very highly it could do 200 mph. A Corvette (LS7) has a drag coefficient of .28 and weighs 3179 pounds, and has a power to weight ratio of 6.2. An S2000 weighs 2835 lbs, has a power-to-weight ratio of 11.8, and a non-listed drag coefficient. So you're trying to say an S2000 with 11.8 pounds per horsepower is going to hit 2000 MPH with "different gearing," when a Corvette with 6.2 pounds per horsepower tops out at 198?
