Just curious from owners whether your happy with the power or wish you went with more/less?

Good luck finding anyone on this site wanting less power....

Are Those Intercooled

Yes

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.

Good engines

Not to try and throw this thread off topic but i was wondering what would be the advantage of buying a 600sc versus buying a 525 and putting a whipple on it?

something in the work's for more powre

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.

525 is a great engine. I've run the pizz out of them and they keep going
