Extra hp out of my 340.

How can a dyno operator come up with random correction numbers? You’d think there would be a correction factor table based on specific components the vehicle has that you would add up. Maybe that’s what they do, I dunno, I only operate turboprop test cells, not auto. A 3*F miscalculation in temp means a 1% power efficiency inaccuracy here - about 250 in. lbs. torque.

340 has 9-1 compression and the pistons are in the hole? Turbocharger sounds better and better.
