Tried removing exhaust to see if restriction was there, but same results, same goes with removing the suction filter.
Wanting to break 400whp, think 264/264 BC Cams & Ti Springs (of course), + Freddy Intake Mani will get me there? |
That is what I normally see from the gtx2867, @19-20psi boost and running more boost is an option. The 260 cams are better suited for the engine and turbo on a street setup. I wouldn't recommend bc anything. Shifting the power to the right, does help a lot, but you still have room with your current cams.
If you do turn the boost up you can hit 400hp but that will be at the end of the power band and the torque would have probably dropped off significantly. Most gtx2867r users don't mind that.
Because they make a butt load of torque before 5krpm
