So the TC 76 has a 4" inlet and a 2 1/2" outlet?

"60 series cover is a 4" inlet and 2.50" outlut on the TC76"

"The TC uses a 4" inlet cover not the 3" inlet E-cover"

How would a TC76 (60 series) with the F1-68 wheel and 1.15 A/R housing spool on a 370ci motor for the street with target of 650HP at the crank? (I'm looking at a used unit)

Will the 1.15 lag too much vs the 0.96?

I like the small packaging of the TC vs T...

the F1-68 will be the choke point with 370 cubic inches but that housing will help, no bones though, spool time will be VERY little and boost will hit hard!

EDIT: the 0.96 will be bad for that motor, spool will be the same as the 1.15 but make less power and work the waste gate harder. Definitely go with the 1.15

That is why we have the new TC7876 coming. Will drop right in place and will have a much larger F1-76 turbine wheel.

I wish they had that when I was running a TC76. I think the majority of users max the turbine side out before coming close to the turbo compressors potential.

Its a larger turbine wheel version of this popular platform. Let us know if you need one or one of the regular TC76's. We will beat anyone's pricing on them.
