i totaly maxed out a turbonetics t76 and couldn't run in the 10's. had to add a little nitrous to get it done. i also had a tail wind. cold night, 1500' elevation, open down pipe. like i said, he is doing something right
whats the specs on that turbo? is there drastic weight reduction on the truck or just the normal stuff?

(at least before I ported the heads). Just need to keep the RR's below 6K. I have blowen up two turbo's allready up hear trying to make boost.

I wanna run 17 to 18 lbs.
Here are my build specs:
forged 370 9:1 CR using a VIC jr manifold with WCCH Edelbrock 72cc 215's
Custom reverse split spec from Rick @ Synergy
T-76 s trim .96 AR, basically a GTK 1000 without the black cover.
Alky contol meth kit
FLT level 4 80e
2 step, possible trans brake. haven't decided yet.
For now stock 80E TC with 3.90 gears
A 50 dry shot of NX
3" DMH E-cutout as far up as i can put it!
My truck is a 2wd and probably weighs about 4200lbs.
I want low 10's!!

Also note the higher the RPM the more loss you are going to get through your I/C. At sea level a 6.0L @ 20PSI will consume ~76 LB/min, a T76 can flow 93 LB/min maxed out. That's with no I/C loss factord in. Figure a 10 LB/ min loss on top of that. So at 5500RPM @20PSI you will need around 86 LB/min which is pushing the T76 to the max. Figure in my 3-4 PSI loss for altitude and you get 16PSI, and that is about what I have seen. Try to spin that 6.0L 6500RPM, and you need 100+LBS/min, and that is T88 territory. So why cam your engine to make Peek power at 6K + RPM? Your engine combo, and turbo need to be able to work together to get maximum efficincy.
