What would be the difference in power and spool up between these two turbo's in a 408" twin setup? I currently have twin 6765's but one of my new precision 6765's is hurt (dragging bad). I will send it back to precision to fix but i try to never miss a good opportunity to upgrade!! Thanks for any info! tracy

How did the precisions spool? How big was the exhaust side of them? My twin tc 76's .96 a/r spooled by 3500 with an 8.7:1 402 and gave me plenty more than I needed. The tc76s are rated to 1000hp a piece.

I have two exh housings, .68 and another set of 1.0 divided. The 1.0's on my 370" would build two pounds of boost on my trans brake within a second or so at 3400rpms. I have not had the 1.0's on the 408 yet but the .68's spool like crazy. I have a 3400 rpm converter so boost comes in really quick.
the billets are supposed to be around 800hp a piece. Two should be able to put down 1200 - 1300 rwhp.

[QUOTE=TracyRR;15135520]How quick is your car and at what boost level? Bad *** car by the way!
My car went 9.13 @ 151 on 15psi with a 1.36 60'. Was hoping for 8's this year.Now the motor is done and I'm selling the twins in favor of a healthy single.
Thank you. Now the car is collecting dust in my garage until I can afford a new motor.

I would go with billet PT76s over TC76s. But, ultimately I think it just comes down to what your goals are hp wise.

I think what you have now will carry you well into the low 9's high 8's if you really pushed it.
Is there a reason you want to go bigger? More HP? Higher RPM range?
If not really you have a good set-up now, I know it gets boring after a while having the same set-up, but I can tell you not having your car for months is even more boring. Ask me how I know.....
