Good stuff Doug.

What compression would you guys do with 93 octane?

From what I’ve read, 93 is pretty safe into upper 12 to 13 over that can be done but is pushing it.

Safe is a moot point if you have to pull timing to make it safe. 12.5:1 with 93 and you'll be pulling timing. If the 93 is just to get you to a track where you switch to race gas that is a different story.

What a beauty, very nice numbers.

I'm using the 70mm Pro Series black TB:

So far its working great and likely helped me pick up some top end torque/power over the 68mm TB I was using before.

Awesome Build, love seeing people still building the B series.

I built a 84mm B18C1/ 10.5:1 with ITR cams, made 206WHP and 143WTQ (dynojet #'s) with a CAT'd 2.5" Hytech exhaust. The extra displacement is awesome

Have you considered using the RDX injectors?

This is the kind of b series build I want to do. Must be such an awesome engine to drive.

The most difficult aspect of RDX injectors is finding a fuel rail that properly aligns and seats the injectors. Many on the market are simply adapted for RDK, leading to improperly spray angle (less power) or leaks.
