Project Spyrocket Options

[Patterson353]

As some of you know i bought the spyrocket off my brother (Iron Goat) a while back. I put a big 16g, 660 injectors, 255 high press fuel pump on it. It already had a fidanza flywheel, Act 2600# clutch put on by my brother. Nate has tuned it a few times and he had it screaming. Well i'm still seeing knock so i'm going to change a few things. First the lifters and then move my maf to see if i cant get the trims to be more consistent.

What I try and look at when building cars for multipurpose, is not necessarily the max power, but the best all around power curve. If you can sacrifice some top end horsepower and beef up bottom end torque/smooth the overall power band, you're going to get much better performance if you still want to do some autocrossing, street driving, etc. It's nice to be able to say kick up the boost for more HP when you need it, but to me a smooth power curve that's beefy over the whole rpm range is much better than a high peaking curve.

Again with this philosophy though, you want good drivetrain components. You just may not need as heavy duty of engine components, but if you're going to do it right and can afford it, get the best so it'll last longer. I'd think a well ported head would help you as well, even if it's just a well ported stock head.

There's a good program out there called Desktop Dyno, that lets you plug in displacement, cams, basic engine mods (turbo, induction, headers, etc), and gives you a rough HP/Torque curve. It'd be worth checking out if you're going to spend some serious money.
