how much power are you guys running on the stock s550 block ?

[schmeky]

The stock motors can't take prolonged intervals of boost since the ring gap is not set accordingly. Short runs are fine as long as the fueling and ignition parameters are optimized.

This is not Gen2 or 3 specific.

Is this from Whipple’s claim (if you have a S2 Whipple)? What did you get at the wheel?

I dyno’d at 650whp@7500 in 4th gear (3.31 rear end so can’t do 5th on the MT82). But 533wtq which equates to a probably higher hp if I could dyno in 5th. ~92-93 octane, SAE, Whipple cal. I’m guessing an 11% loss on the manual but too many variables, I have no idea what my crank hp actually is.

BTW zero problems so far but I’m hardly pushing it.

Yes and I even looked at his most recent posts and other than being a little aggravating, I didn’t see anything agregious.

Maybe it was the flood of cliche young guy, new car/want power/gas mileage/perfect reliability questions all over the forum?

If that's the case that's not a reason to ban him.. just ignore him. I'm guessing he pissed off a moderator.

Well, in addition to the longevity concerns, you're going to have to upgrade many other aspects, particularly cooling. Lots more HP's = way more heat.
