Guestimated RWHP???
Hello all:
My car is almost ready. All they have to do is work out the tune.
I currently have the TTi race kit (Turbonetics T76GTQ trim), built 370ci iron block with 8.5:1 compression, 60# motrons, factory ECU w/LS1Edit tuning, which is working out very well, and a TH400 w/3000 stall converter. I plan on running about 15PSI on pump and about 20+PSI on race gas.
Just wanted a guestimation from everyone. On a good tune, what do you think she'll do? This will be on a Mustang dyno.

What kind of heads/cam?
I am gonna guess 580-600rwhp @ 15psi and 700rwhp-720rwhp @20psi all on a mustang dyno...

Whoooo Quick I think you are way undershooting it... I make 560 with an STS and a 67 Trim turbo at 9Psi. I think 98 is pretty close... I dont know what it will do at 20PSI however... 850 maybe

A T76 with a Q-trim at 20+psi is going to be tough to make good power (if any more then 20 without side effects) without backpressure becoming a big issue. Also the IAT's will be screaming...make sure to pack plenty of ice in the IC.
~95 lbs/min, 2.36 PR, you will be way off the compressor map....~55% efficiency. Your compressor outlet temps will be floating ~410-420DegF.
Just something you may want to think about.

So, what PSI nets the best efficiency for my setup?
I noticed in INTMID8's post on a similar setup here (TTi race kit hot parts) he was able to make around 900RWHP (though it was an M6) but he is running a bigger A/R on the Innovative Turbo than my Turbonetics (1.15 vs my .96). Or, are there more differences between the Innovative and the Turbonetics as far as efficiency/power is concerned?
I don't know if it is possible to switch to the T76GTS with this TTi race kit. Would that help any? Guess I'll have to make a couple of phone calls. (or if mightymouse or anyone else have input, please chime in).

In order it would be...
O, P, Q, X, S, R , S4 and TM1....forgot about the last. The TM1 is new and is very hard to get right now.
BTW, the X is a touch smaller then the S. Its an R-trim wheel with a step cut into it.
