85mm Throttle body upgarde

Post by SUBLIME51 »

I've added a BBK 85mm throttle body and was wondering if there is anywhere I can go to make the proper changers to the air/fuel intake, I have a K&N CAI and I'm using the 93cai tune.

No gains to be had from an 85mm TB on a 5.7. Even on my heads/cam 6.1 there was no gain on the dyno between a ported stocker, 85mm or 90mm. The stock Hemi TB flows more then enough for anything short of a stroker or forced induction.

I beg to differ, at least I got a bit more wheel spin and my 0-60 went down to 5.34s

The dyno doesn't lie. Between the a ported stocker, 85mm and 90mm, my heads, cam, header 6.1 showed a massive gain of -.2hp. Yes, it LOST power. We can chalk that up to dyno inconsistencies, but theres definitely no gains to be had.
