I'd be interested in seeing a dyno comparison as well.
You happen to have any dyno sheets of the t-66 with a Q-trim or P-trim?Sound Performance said:We tried dynoing a T66 Ptrim vs our SP63 Ptrim and the T66 made 2 more RWHP but made 80 Ft-Lbs LESS of torque due to the increase in lag. We switched the 66 to a Q trim exhaust wheel and had much better luck. It made more HP and TQ that way with LESS LAG.
I have never been a big fan of the 66 and P trim combo.
Our new SP70 - Q trim seems to spool better and make more HP than any 66 combo we have tried.

Steve Jarvis said:No they are not ball bearing turbos. Ball bearing turbos cost more, don't seem to make much difference to performance, and can't be rebuilt. A non ball bearing turbo will last at least 100,000 miles so I don't really see the point. For the additional price of a ball bearing turbo you could almost have your turbo rebuilt after 100,000 miles and be ready for another 100,000 miles.
Later, Steve
SP has a whole new line up and the biggest turbo they have is the SP88.I was wondering, whats the largest turbo SP makes? the SP74?
