Dyno Results 98 Z28 stock bottom end and heads. TR Blower cam, LS6 intake, Pacesetter long tubes, no cats, Flowmaster cat back, 42# injectors, racetronix fuel pump, ATI Procharger P1SC with dual intercoolers, with 3.4" 6 rib pulley showing 5.25#.
458 hp/ 428 lb/ft. Thanks to Justin (VMP) for a great tune and helping when the damn ATI balancer bolt backed out (it was too long and bottomed). Got it all tuned before I backed all the way out. Shortened the bolt, chased the threads, red loctite, and 240 lb/ft and it is all fixed.
I don't mind full throttle runs. I just always hate full throttle runs on the dyno. Sounds like the car is about 10k rpms.

Here is the graph. The second run is where the pulley came loose. All fixed, and would probably pull a hp or 2 more, but close enough.
Thanks!!!!
Thanks!!!!

That's what was funny. I made 5.1# with 3.7" pulley, LS1 intake, stock cam, and magnaflow exhaust. Swapped to 3.4# pulley, LS6, TR cam, and flowmaster, and made like 5.25#. Lost boost numbers, but obviously was flowing well. This just reinforces why Bob recommended the D1SC upgrade, and why I should have listened to him. When I do a stroker some decade down the road, I will have to upgrade. I will probably go F1 or whatever the next bigger one is, but I could have just used the D1SC and been happy maxing that out.....
