Right now im running a maxrev style log mani. what would i gain in terms of hp/tq and spool up by switching to an equal length manifold? Setup is a b16a: 9:4:1 comp. t3/t04e 60 trim .63 ar, @ 13-14psi...need to know if its worth it or will the log mani suit me fine for now?

 

That's the question of the year. The bad thing is, I don't think anyone has done a true back to back comparison yet. All you can do is speculate. If you look though, cars with equal length manifolds are making more power in general, it's just hard to put a number on exactly how much.

 

from most threads it seems they are making more power with less psi. correct me if im wrong.

 

you will benefit greatly with an equal length manifold.

This has been beaten to DEATH. Will someone just host some damn dyno time so we can set some **** straight? A 3-400 whp car would be perfect, because its the "medium" of the people out there today that are looking for that last EDGE.
So till this happens, "Its all speculation."

On a side note, the butt-ometer, and the Spool-omometer works great on all my cars I usually notice a 1000rpm gain between log and tubular on the same turbo, same car, just the different mani and DP(3" Dp previously as well).

 

sorry this is off topic, but of all the many tubular manifolds out there for B-sereis, which ones actually work? and which ones are crap? and does Price always matter? i've seen $1400 manifolds and i've seen $300 manifolds, does price really play a role in hp gains? thanks
