Well this stock engine has a very flat torque curve.
Blowtus: I agree with you on that you have to compromise, but peak power means nothing if you only have it there for a 1-2k RPM. To me it does not make sense to create the most power out of an engine if you can create a smooth power curve that has an even and/or smooth amount of power over many RPM's giving you much more flexability on how you drive and setup the car.
Maybe I am missing on how exactly VVT works. I have always assumed that it was for people that wanted a daily driver that got good gas milage that when you stepped on it gave you some more ponies to work with.
Maybe part of my problem is too that I grew up with American V8's and I never had to wait for the power to come in like you have to wait for in a VVT engine. I hate having to wait, no matter what RPM I am in I want some kind of power, be it either torque or HP.
I looked at some VTEC dyno's they are not as peaky as I thought. I just don't like having to revv the crap out of something to have anything to work with.
Vain: I know they do but I am still confused as to why someone would want to race an engine like that, but alot less confused now. I think it's more down to now that I just hate the idea of waiting. True in racing you would normally be in the higher RPMs, but nobody is perfect and especally with production classes you are not going to be able to change gear ratio's to make sure your in your power band for every corner. Maybe if I took a Civic Si out on a track it might be different but I just don't think the Civic engines are the best solution for a race engine.
Tristian: maybe thats why I thought they were peaky, the new dyno's look good, but you still have to wait until 5k to get any power. I mean jeez I am already close to my peak power by then =) Turbo kicks in at 1700RPM in the SRT-4.

I am still confused as to why someone would want VVT in a race engine? Can someone help me with this?
With VVT you get less power and less torque than you would if you had a cam that was perminent. With this you get a very peaky power and torque curve, I have never heard of any racers actually wanting peaky power.
It would make sense to be to have a level torque curve with a linear power curve just after the troque curve that is present through all RPM ranges.

That is a possability too, but with my Motherboard manual requiring at least a 550 for my processor so 600 might have been just too small. I don't know I will never know but thats what I am sticking too =P
