Old manifold and 38mm waste gate compared to the new manifold & 44mm waste gate. Notice the inlet & outlet size differences on the manifold.

yummy. To bad I don't have a SBC to bolt those too. Y'all need to make one for the Titan, so we can blow up the tranny even faster.

We've made 650 BHP with dual 60-1's on 91 pump gas, NO intercooler/water injection, and 9 psi with a 366 SBC.


The same engine made 1120BHP with an intercooler and 100 octane unleaded with 20 psi.

holy crap. i was reccomending dual 50 trims, for quicker spool. or do those manifolds have a T4 footprint?

Yes, T4 flanges. You will have to use an on-center housing as well or the passenger side turbo won't clear the valve cover.

We were using P-trim wheels and .96 A/R housings and it sill made 10 psi by 3000 rpm with 8.0:1 compression. He's got more cubes and probably more compression so he could run Q-trim wheels and a smaller A/R and make a bunch more power than we did.
