2.76 pulley.Made a huge difference! A big thanks to HPP racing and Manny for the tune! Those guys are first class acts! Fuel pump duty cycle maxed out at 4200 rpms...Kenne Belle boost a pump did the trick!
It hit 12#s...even with the larger heat exchager the eaton still gets heat soaked fast....the cylinder heads are really holding me back. They couldnt add any more timing otherwise it would start detonating. All i can say is that manny from HPP is the best of the best. The guys went above and beyond what they should have to help me out! Anyone with a similar setup should be aware that the fuel pump duty cycle is at 100% around 4200 rpm even with a Ford GT fuel pump.
