Add: - bosch injectors: +10 hp - no cats: +15 hp - no accessories but alternator: +20 hp - vacuum pump: +10 hp So the power getting into the gearbox is now 530+55=585hp Now remove a quite conservative 10% (I hope, time will tell...) and you get 527 hp. With a non optimized drivetrain, you would need 620 hp ... not far from my non effective 630 hp goal at the flywheel. Quote:

Superfinishing of parts is not very expensive. What is demanding is time, some coatings, hybrid ceramic bearings,... Thanks for your support Bob!

Cats: Assuming you already have headers from what I've heard you will only net about 5hp by removing high flow cats (aka Random tech 3in). The vacuum pump is an interesting idea, I think Kurt White played with this idea some time ago and netted a small gain. I have been wanting to try this myself. My thought is to rig a small electric pump to a micro switch on the throttle body for a full throttle only activation.
