On some other forums i visit frequently, we have a dedicated thread where people post thier engine combo's and dyno's/timesheets to help other people build engines and prevent wasting time/money on useless "upgrades" like Airfoils, electric superchargers, etc. I have searched here and have not really found nothing of the like.

Personally, i dont think a performance engine is worth its weight if it doesnt have at least a 1:1 power to Cubic Inch ratio. I personally have an L98, so my goal is at least 350hp... which really shouldnt be an issue.

I am having a hard time deciding on what route to take, as there are so many. Should i do intake, exhaust, CAI, etc? Or would it be more worthwhile to just go straight to aftermarket heads and decent camshaft and headers?

If you want to participate, please post your engine build and some dynosheets and/or timeslips in this format:

Engine Size:
Rotating Assembly:
Heads:
Cam:
Intake:
Headers/Exhaust:
Computer/ECM:
Other Important Information:

Dyno/Timesheets:

Also, if you want, post the mods which you noticed made the most noticeable improvement, or if you had to do things over again, post what you would have done first through last.

If there is already a thread on here like this (which i have not seen) please dont flame and just disregard.

See signature. You should have no problem getting 350 crank horsepower. My suggestion is to buy the best heads you can afford and go from there.

Forgot to turn it on.
