By "stop making horsepower" they begin to bottleneck compared to other heads (aka honda's for example). I ment high rpm, not high horsepower. Latenight typo, I'd go edit it, but since I was quoted by 3 people it wasn't worth it. The 2.1 is a great idea for a motor. I love all the theorists in here.
Cher-
Brent=not a dsm transmission
Shep=Not a "dsm" transmission. We know his dsm based transmissions are hardcore, but now he is on a dogbox. I am sure he switched that up because he was bored.
I know they make power up top. The power isn't hard, but making it work as a CAR, not a motor, is the fun part. I think we all know how that works

Justin- I agree everything has bottlenecks, but if I were going to go through the trouble of a smaller displacement motor to make up for it in rev's, I would have to go to 9500rpm + and I would want a serious power band up there. The headwork/turbowork/transmission required is beyond the budget of 99.99% of the dsmer's. IMHO its just not worth it to do it "right". Unless you have some no holds bar setup, it isn't worth wasting the cash.
Jakey- See post for Justin.
Steve-Just hardblock it if you are really worried about it. Remember, it is a drag car
.
Craig- I understand about shep's trannies. They are great units and work awesome. The only problem with going the 2.1 vs the 2.4 is the costs involved. It is just not cost effective, in my honest opinion, to go the 2.1 route.
Shane-I totally agree. Laggy turbo's own for that problem.
