The car looks flawless. I commend your efforts! If your chart stands true, you are right there with the Euro horsepower wise. The only car I've driven with a cam gear "upgrade" was a Euro M635, and I was unimpressed. Had he gone to a larger air induction system, a custom chip, a beefier exhaust, and the like, I assume the difference would have been more pronounced. His car was far slower than mine in the low range. From 50-100 it pulled like it was supercharged, however.
