This is a manifold we made for a customer of ours. Stainless Steel , tubular design, TopMount. Sr20 with STOCK BOTTOM END. T3/T4 Turbo, cams, springs, ret, 780ccinj.
Here it is, apolagize for the crappy pics:
Here is his PUMP gas Log manifold vs our manifold, same boost 19psi
Red is our manifold, blue is his old manifold.
thats a 50whp GAIN !
Race gas vs PUMP gas with TDF manifold
You can tell his turbo is maxed out. It flatlines on race gas cause the turbo just cant carry that much boost. We opted to stop at 440whp on a stock bottom end to keep it safe.
This is 10psi OLD manifold vs 10psi TDF manifold
As you can see he pretty much gained 50whp no matter what. he lost a little bit of bottom end power but gained a bunch of power an TQ up top. We did not touch timing at all, just a/f ratios.
NO NITROUS WAS USED , ALL TURBO
SR20 ftw
