What's your gas mileage like?

Looks good man keep it up.

thanks i just found out that i need to sell my intercoller setup and get a side mount setup wtf

Vadim you didnt read that link correctly. They dynoed with the log untuned pretty much tuned it a lil bit. Then they swapped manifold and fine tuned it. Just swapping manifolds doesnt give you the results you see there.

No sir, I read it correctly. Here let me quote some...


Trying different AFR's and Timing values = Tuning = fine tuning.

Cost wise a log is probably best way to go, but just bear in mind that it will probably flow similar to the restrictive stock manifold.

i like log manifolds personally, i havent really seen the restrictivness of them on my current setup, tubular manifolds are superior over log, but there are some benifits to the log manifold.

umm why... i dont think i have even seen anyone running these on our cars

On our motors log manifolds spool 100rpm sooner then tubular. On others, it can be 300rpm or higher.

Found the dyno on the log vs tubular: http://www.full-race.com/articles/sr20_turbo_manifold_test_writeup.pdf

On a B Series motor: http://www.full-race.com/articles/Bseriestest_writeup.pdf



I've heard of it a few times. Not the most efficient setup but works.

ill get pics of why in the morning

You guys can justify your log manifolds all you want, but I can tell you it is way off. The main point of tubular manifolds and equal length is for spool characteristics. Faster spool and more power with a wider power band. They support bigger turbos and more horsepower where a log manifold will eventually hit a wall. I had three log setups before going tubular and will never go back.
