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?
