rpm 2 changed the design a little bit and i know it made more power but im not sure how much tho.
i think i read in a summit magazine that the rpm2 made like 17 more horsepower than the rpm 1
but thats in a magazine and i doubt it was that much more power

The RPM ranges are different. The RPM 1's RPM range is from idle to 5,000RPM.. The RPM II is made for higher revving engines, from 1500 - 6500 rpm. So if your engine only makes power to 5000rpm, then the RPM II is only going to hurt your performance. You must match parts correctly in order to have good performance. Mismatched parts are a waste of money.

like they say theres always someone out there that knows more than you.
