FAQ’s: WILL BE UPDATED AS THEY COME IN

Developed off of the 12V DIY kit. After years of trial runs and different styles, we did some testing on the MK3 test rig. After a long day of testing, we have data to show this manifold made 30whp more then a stock manifold. Same dyno, same car, same operators. The test was actually done to learn the difference between the Offset Runner (equal length to valve) Against the straight row of mouths inside the plenum. The two manifolds tested within 4whp of each other. Peak power now is made at 6800 RPM, and carried all the way to the 7300 Rev Limiter.

Disclosure: Not claiming you will make 230 whp….. every dyno is different, every car is different. Does this car make 230whp? Maybe it only makes 210 doing this test somewhere else. What we do know is that it the manifold makes significant gains with the same dyno and same operators.

MISSING data is the graph from the cam’d runs with stock manifold which we made 199whp. I will get back out to the dyno and pull that off the computer next time im there.

Test Car, has a sloppy built garage engine (questionable block, and old head off of another old engine). mk4 head gasket, TT 276 cams with heavy duty valve springs, TT chip that is paired to the cams, factory headers, 3” to 2.5” exhaust with 1 resonator, and 1 bola muffler.
