I bought a T76 a few months back because i was getting it for extremely cheap.
What i need help with is that I am wondering whether or not this thing is going to spool.....
I am looking to tune my EMS for 8-25 psi. I realize that I wont be able to do that with pump gas, but I need to know how well these things are spooling for you. If you look at my sig you'll notice what i have done. Let me know what you think please.

By the way what kind of HP numbers are you guys laying down at what PSI?

 

Whats the a/r and what type of engine porting do you have?.

 

It's got a 1.15 A/R ratio. 4in inlet, 3.5in outlet. I am most likely doing a Street port, but am still considering a "small" Bridge port.

 

Street port won't be enough to spool it in a decent enough time , you'd need a partial bridge , like I have or a pp , semi pp etc. . That is a big turbo I am using a TA51 with a 1.22 a/r housing and a 71mm turbine wheel with a half bridge , and I think its awesome on the street !!.

 

its really that big of an increase in air flow with the BP? Wow, I knew there are huge gains w/ porting but really that much???
