Tubular VS Redesigned Protech log
I have been thinking about this. But I was wondering what kind of power gains could be had by switching to a tubular manifold. If I am hitting 400whp on 20psi or so where would the tubular make the difference?
I was talking to a guy yesterday with a b16 in his honda. Stock motor. He had an eql length manifold and a t3/t4 57 trim turbo. He did 319whp on a mere 9 psi of boost. I prob would be 350whp on 16psi. Granted he is a lot higher compression than I am. But I hear from ppl here all the time that I should hit 400whp on 15psi yadayada. But the same people who claim these high numbers don't give a whole lot of insight on what could open up th motor to make more power. Here is what I can do to get more power so far.
a real Cold air intake,
smooth out intake plumbing,
play with ignition timing/tune.
The other day i set my timing back at stock and let my buddy drive the car. He took all of his friends in it and played with a greddy turbo 350z and pulled him pretty good. But when he came back he said the car felt slower than normal. I set the timing back at 19* and he took it out again. He came back and said that the car gained 50whp with 4* of timing. So now I know my tune really sucks. I shouldn't have to set my timing above stock in order to make good power.
Would a tubular manifold make a huge difference? I really wanna keep AC and I don't wanna have to deal with cracks in the manifold. Should I keep this protech shorty? I really like the quick spool it has and it keeps the engine bay somewhat clean and compact. What do you guys think?
