Just got back from dynoing my truck today. Stock bottom end, Comp Cam with Dual Gold Springs, 60# inj., 6L80e swap, 2500 stall, Trick Stage 3 Intercooled Turbo Kit. At 6 psi it made 440 rwhp @ 5300 and 542 rwtq @ 4000 on a Mustang Dyno. Took awhile to get the right spring in the wastegate and get the boost under control. Had a couple of scary moments at 14psi making 660# of tq at 4200. Looking to upgrade the fuel pump so next time I go back, I can turn up the boost to 10-12psi. Does anyone know if a flexfuel pump assembly fits a non flex fuel nnbs with no mods? Plug and play?

 

Damn, 100ft/lb more torque then HP has got to feel awesome! Im guessing this is a 6.0/76mm combo?

 

You guessed right. It does feel real good but I'm hunting for the 525rwhp range. That should land me in the 600# TQ range. Then I will be very happy.

 

What cam are you running? Seems like it might be a low duration, low lift cam to get those kind of torque numbers.

 

228/238 .571 .586 117lsa

 

I'm guessing the turbo is a little undersized is why the torque is so high. Nice numbers

 

Its a 76mm with a .96 ar exh. housing. I think its perfect. Boost comes on almost instantly. WAY better then my old 6.2 P1SC Procharged kit.

 

Nice numbers. If you decide to go bigger on the turbo let me know, I think it'd be perfect on my truck.

 

The compressor is fine. I was talking about the turbine pretty much.

 

Yea seems like those 76/75 turbos are ideal for a 6.0-6.2L and the p-trim and q-trims are good for 4.8/5.3s.

In any case, those are great numbers for 6psi. Cant imagine what 10-14psi would be like.
