This morning I went to participate with the rest of our mustang club at a dyno day they held with the Mach 1. Was $50 for three pulls. I was curious to see how the new engine stacked up to my expectations.
I was 1st in line and glad. Done quick. The car did really well. Even the operator was very impressed as he almost never sees old vintage stuff make those sort of numbers in a street tune. I was hoping for 1hp/ci at the rear wheels and I exceeded my goal with 362hp/350ft-lbs. Over 416hp at the flywheel is nothing to sneeze at. The old engine was at 287/311 so a measured 75hp/39tq gain at the wheels. The same exact dyno that was used for both sets of numbers. Just eight years apart.
Right after my car was done he strapped on a 01-02 WS-6 TransAM with a LS motor, 6-speed car with bolt-ons. Annoyingly loud exhaust car. It only managed 342rwhp. Made me feel pretty good.
The difference on the two runs was the lower one was without the air cleaner, and the second darker run was without. Only a 3hp difference. That could simply be a run-run variance. So my air cleaner mods are not causing a restriction, which is what I was concerned with. A good day.
