Since we are talking about my dyno, I though i jump in here. Dave posted his J607 corrected numbers, we were making pulls at 600 RPM per second with a 45lb flywheel. Now most of you should see the issue, all that weight takes Hp/TQ to accelerate. My dyno also has inertia correction which gives the same hp as a step test.
attached is Dave's STPIPw and STPiTr
