7 psi gave 723 hp at 5400, and 860 lb/ft at 3400. Peak torque may have been at a lower rpm and HP was still climbing at 5400. We did not test below 3400 and Laz stopped at 5400 because we did not discuss what valve springs I had. I would have told him to go to at least 5800 if not more. we stopped testing because of several factors... it was over 100 degree in the dyno cell, IAT was about 200 degrees and we did not want to wait for a cool down to try more boost since it was about 9 pm and I had been up since 4:30am. The engine is in the truck, but no turbos yet. Before installation into the truck, i swapped from a hydraulic flat tappet Lunati cam 226 int./234 exh. ,0.494 int./0.513 exh. ,110 LSA to a Comp hydraulic roller. Intake Duration at .050 Inch Lift: 236 ,Exhaust Duration at .050 Inch Lift: 242, Intake Valve Lift: 0.544, Exhaust Valve Lift: 0.541
Lobe Separation: 110 . I'm currently collecting parts to upgrade the transmission from a simple B&M Transkit to a one with a billet steel front drum, 300M input shaft and the rest of the typical goodies.
