The results shown here are listed chronologically and represent the power made before and after the Procharger was installed. Test 31 was without the blower and just running the ACCEL DFI. To baseline the motor's power. If you're not interested in a blower, but still want a great fuel injected street engine, this package ii one to look at. It made good torque, even though the cam was very big and the peak hp numbers are very respectable. Test 32 was actually one of the last tests we ran that day. It was after we'd tried many different pulley combinations and found the best one to be the pulley that ATI recommended we run. It made over 14 psi.
