Message: [QUOTE="KCTurbos, post: 1541644, member: 13852"] Don't want to muck up this thread... but thought this would be nice to add. We just recently had a truck on the dyno with the same turbo. sxe72/87/.90 Truck had 350/200s on it but still rocking a single hpop while waiting for his duals to get repaired so he had to run a 3.0ms tune. So the top end is WAY down. We had a 1999 with 238/80s and s364.5sxe the same day. So it was pretty interesting to see the differences. From the dyno graph you can see the s364.5 spools about 400rpms sooner, makes more peak tq, and actually more HP... but you can see where the s364.5 starts dying off around 2500rpms and HP is all downhill from there. The sxe472/87/.90 is much laggier on the bottom end. At 2200rpms we are talking about a loss of 400 ft/lbs of tq. But the really cool thing is that power just keeps climbing all the way to redline, which is exactly what you would want in a drag race application. But for daily driving it kinda sucks because of how late the power comes on. With more fuel it obviously would have made a lot more top end power. But this is great to show the spooling characteristics of each setup. [ATTACH=full]178236[/ATTACH] [/QUOTE]
