Weight empty is between 7200-7500 lbs depending on how much fuel I'm packing. At 1500' elevation I could pull 1450*F w/ box on 3x5 and it would climb to 1500*F. W/ box on 5x5 it went straight to 1450*F and then climbed to 1600+ fairly quickly. These runs were all made from 60 MPH w/ zero boost to full throttle... letting off around 90 MPH.
At 5000' elevation and box on 5x5 I can hit 1600*F in about 4 seconds... it hits 1400*F and then is a steady climb to +1600*F. Before I changed my housing to the standard one it would instantly go to +1600*F (I say +1600*F cause once the needle stops moving after it goes past 1600, I don't know how high it's actually going) on any Comp setting above 2x3. Now I can't go over 1400 if on 2x5, but can get to 1550*F on 3x5 and +1600 if I'm above that.
Spool up is still decent... I lost some by switching housings, but not much, maybe 200 RPM's if at full throttle. Used to hit 46-49 PSI boost on 5x5 though and now only hit 40-43 PSI, which is a good thing (headgasket). It also pulls much harder on the top end now than it did w/ the KS housing. May end up going to a KS housing and standard exhaust turbine... Ken said it'd be less back-pressure than what I'm running now, but roughly the same spool.
