topmount log manifolds

[Nyteryder]

I had a question if this log style manifold is gonna keep me out of the 400whp range with this set up and does anyone have dynos of there set up with this type of manifold. Right now I want to work on other parts of the car and go back and get a peak boost mani late.rWhat numbers should be expected at 18psi with my set up. I am putting a new motor in my car this week with this new setup: Basic bolt ons w/ hks 264 step 1 cams, topspeed intake mani. 72lbs inj, enjuku t3 fab kit minus there turbo, t3/to4e 57trim .63 a/r stage 3 wheel and power fc. Those are the new mods that count.

340-355ish I'd guess. There's a guy on Fresh Alloy that was running that turbo w/ an enthalpy tune and a full race manifold making 438whp at 25psi The log mani is going to kill you. http://shop.hybridynamics.com just released a new manifold similar to the peakboost (in price too) with some improvements (FYI).

that is the same manifold i was looking at.. mainly because it came with the dump pipe and doesnt cost 700 dollors

I was hoping to around the 400whp mark on some c16 fuel, 340 seems alittle low for a setup with cams and intake
