maybe consider one of these

Well, it really comes down to air velocity, if you aren't moving past .4 mach or so, there's no gains, the more hp the larger the tubing you need to keep velocity in check to avoid turbulence. I expect 600whp or so you'll start to see SOME gains with larger intake manifolds etc.

Then again, we should be talking charge pipes before that anyway, probably some people are undersized out there, and many are over-sized just creating lag needlessly.

I don't think the exhaust manifold matters either way other than that it'd be hard to make enough hp to be over that 600hp figure, if you mean it that way I'd agree. Though short runners can do it, logs probably can't. (log term is getting a bit too general, a short runner is NOT a log, thus the pfab really shouldn't be called a log manifold, it's not cast)

 

I would highly consider Trackforged they make quality stuff

+1.. car has seen 640+whp and 472tq on their manifold.. 640 only because I couldn't Rev past 7k because of an Injector problem.. I'm happy

 

Thanks guys!

No I'm still here, had my laptop stolen and Im tired of watching a bunch of people I was asking for help shit talk me. Sorry.
