Also ordered a Walbro 450 LPH in tank fuel pump (E85 compliant) and should be good for 700+ whp 😀

That is a bit optimistic... twin 450s would be cheap insurance.

Well the gasoline chart shows 1000+ hp @ 60 psi.

I guess a second one wouldn't hurt...🤔

Base fuel pressure is 58psi. Adding boost? Every pound of pressure in the intake moves you down the scale. Add E85 and the supportable rate drops again. And so the dance goes...

Decapped the truck fuel injectors:


These should now flow around 75 lbs/hr, compared to 25 lbs/hr.

I see some sloppy going on here! Going to be watching this one. Nice project.

Hmmm. I'm contemplating using the front of the oil pan for the turbo oil return. Looks like your location might interfere with the balancer?
BTW, Easy Off oven cleaner works great on aluminum and steel. There is a lot of hearsay on line about damaging aluminum........All BS. don't worry about it.

I had to clearance the fitting on the backside for the oil pump. The fitting doesn't stick too far out, I will add a 90* turn to avoid the balancer hitting the line.
