Thanks, Brian. Its a lot of fun. Not sure on the injectors once this is on. Its a lot more (4x) air. I was running out of air beginning at around 5500 rpm, not fuel. So, we'll have to see.

Rx-heven... Love your build. Still thinking about following in your footsteps. Almost did it some years ago. As to the TB, its a modified and extrude-honed Rotary-Works 90mm 20b throttle body. (They also make a 90mm 13b version.) I am wondering if that is sufficient for my power curve goals, but won't know till its all back together. As Logan's work shows, there's a lot of experimenting and new stuff to be done in NA. We're only just getting into it and yet there are now a bunch (10-15) of street NA 20b's making 425-475 whp.
