manifold is split pulse,turbo specs I dont know as it was built by gcg.graph will show the boost comes on without too much lag.

regards geoff

how do you get that power tp the ground?? masive power curve down low, looks great!

Altho not having done back to back testing on a ford twin cam yet, I have recently done some testing on a RB26/30 drift car I sponser, and previously we had a GT35 with a 1.06 rear fitted to the car. After switching to a split manifold to go with the TO4Z, with a .84 rear(similar to a GT35 1.06 in size) the turbo makes full boost at the exact same RPM as the GT35 and makes the same power on 4psi less boost with 6 degrees less timing. We are hoping for another 50rwkw on the same boost as previously and timing brought back up.

I'll keep you all posted in a few months, I'll be doing a TO4Z on my new tornado ute after I finish development of the factory turbo and manifold.

hey kyle, adam from up in townsville. have you started making merge collector manifolds for the xr6t's yet. I think there will be a good call for them very soon with all the people making over 350-400rwkw plus the benifits of faster response with a bigger turbo.

how much is to4z set up fitted
