I had them in my '06 42X. They were some of the first ones. I put just under 100 hrs on them and they NEVER missed a beat. I'm not sure if the upgrade was really worth it due to cost, premium fuel req'd, fuel consumption, etc., but they sounded AWESOME.

Well, the advantage for the 525 with Whipple is power, it's a monster, nearly 800hp. Disadvantage, reliability. Not that it's not reliable, but theres no question that a 7.5:1 motor, with 4psi of boost is extremely robust and durable. But, with the 525, we've made 1030hp on a 100% stock engine and its lived, so I can tell you that motor can sure take a beating.
