Default turbo 4.8 on dyno again

little tuning on dyno today. poor little mp70 is out of breath. made several 600+hp runs thru a th400. still on a returnless fuel system running 93 and ton of meth. back to track Sunday for hopefully a 10.** run.

Wow. Nice graph and power. Looks about 16 psi right? Looks like the power is holding steady is that the sign of maxing the turbo? I'm guessing it should keep climbing and not be so flat lined?

I think the power holding steady is more cam than anything, the boost dropping off towards the end is more of a sign I think.


Im impressed that your spinning that thing over 7000!

Impressive numbers out of the baby china turbo. I bet the fender exhaust is helping a lot.

dual nozzles totaling 26gph. we kept adding timing and tq just climbed and hp stayed the same. turbo flat won't support any more power. tq # is up almost 100 ftlbs. just from 3 deg timing. timing at 19* now. from 4500rpm up power is basically flat. more turbo it easily would be over 700rwhp. boost hits 16.5# early then falls to around 14.5. that's the spike in a/f, 2 bar map can't read it.

who needs a damn rev limiter!
