Put my truck on the dyno today. Made 4 pulls, first three made around 630, final one I opened my cutout and made 650.9hp at 5400. Runs were about 14psi, this turbo is really choking out on the top end, falls off hard after peak hp. I am waiting for kyle to hook me up with the new tnetics 76mm with the 76mm exhaust wheel compared to my 68mm I have now. Unfortunately I think I roasted my torque converter clutch trying to lock it on the dyno.



Their means of reading boost shows it at 14-17psi, but my gauge shows a consistant 13.5-14 and correlates with my 2 bar map in my intake manifold.

Is it a multiple disc verter? Good numbers go bigger and shoot for more boost.

Yes, its a circleD billet multi disc. I know there are others that have pushed these converters much harder then me, I just have shitty luck I guess. I want to go to a turbo with a better flowing turbine side so I can run it up to 18psi and 6k rpm.

Are you sure you arent running out of fuel? Or maybe need a bigger cam.

Great #2! Those dyno dynamics dyno's read super low compared to most others. I've been mid 10's at 650RWHP observed on one.

Those dyno's read way way low. His cam isn't too small I ran mid 9's at 145mph with less.

Thanks guys, I'm sure it's the small 68mm exhaust wheel that's choking me up, cam should be good and it's a little rich on the top if anything. I'm satisfied with it for now!

circle d should stand behind it for sure. I have the same thing. 9.5" multi.
