Nissan 370Z Forum - View Single Post - Advice new style Stillen S.C. Intercooler pipe (MAFs at TB)

NissanTracker · 04-30-2018, 01:18 PM

Thanks for the info everyone. Unfortunately, I do not weld. I'm going for a tune this week since I just upgraded to a dual exhaust (Motordyne TDX). I'm going to have the shop weld the piping and I'll schedule another tune with the new pipe setup and report results.

Before posting, I was well aware of the flaws of the OE Stillen S.C. design. The goal was to just move the MAFs closer to the TB's.

In summary, it looks like I will be in better shape, but not ideal(as ByThaBay clearly stated due to UpRev). Since I'm staying below 11psi, as TopGunz pointed out, the bypass valve should suffice. No plans for a built motor so I will stay on the OE pulley.

I do want to get rid of that awful offset coupler used on the S.C -> intake pipe. I could possibly vent the valve 100% to atmosphere and add a filter in place. I am hoping to achieve 370-380wHP on a conservative tune. Currently, I am at 350wHP with mods; HFCs, Tanabe Y pipe, and OE 350z Nismo exhaust (single mid-pipe).

Any ideas if flow rate with that offset coupler will be a problem?
