Okay so set-up is a log-intake 2.2.
Mildly ported 782 w/ good valve job and back-cut valves.
Polished log and ported exhaust manifold.
Brand new T3 .48 A/R.
Big-mouth 46mm TB polished, T1 adapter has had the flange sawed off and welded to 2" OD cast elbow and polished.
Exhaust is 2.25" SV...
Okay so I'm convinced I need to get going on having a big mouth TB fabbed up
for my draw-through T1.
I need to know if I use a specific 46mm butterfly from a specific make and model
or if any one will do?
I'm going to have a machine shop here bore straight through 46mm against the stock 42mm...
