Place your bets, what will it run

My initial thought is......
“Too much gear”

What’s the boost right at the hit?
I agree.. I also have another 3.55 chunk with a spool I can use. I was gonna try the 4.30 first. Just to see how it goes.
It only makes about 2psi at say 3000rpm, reads about 4psi at 4500. Might be a little off as I'm trying to control it when it goes. But at wot 5500 to 7000 it shows 6-7.5psi.
