11, 12, 13 psi... these conversations always get me because I come from the diesel world prior to my Raptor. Truck in sig would hit 40 psi just hitting it on the street. 7.3 after this one would hit 50 psi under load. Some Cummins guys see 60+ on street trucks and with pulling trucks, the sky is the limit...

those are not super charged gas motors they are turbo diesels built way different.

I knew something was different... Is that why i had to use the "special" green handle gas from the gas station?

Are you going to use a voltage boost to help the pump run more consistently?

Something like this?

https://www.lethalperformance.com/jm...-and-play.html

Also 3 gal/min is insane!

Are you going to throw meth on to help with the octane?

900 rwhp is something like 1,110 at the crank! I hope you post what you are working on... I'm sure we would all like to see

You don't want to run out a fuel...KABLOOY!
The short answer is that 11 lbs is probably OK for a while...AS LONG AS YOU HAVE A GOOD TUNE. (Better upgrade your tranny...it's a cheap investment).

I'm going with dual 450's AND a voltage booster....That should get me enough fuel. Looks like I'm going to just fab some rails out of my existing ones. May have to upgrade from my 95lb injectors...but we'll see. I'll have multiple tunes, some for normal gas and some for E85 (which means I need like 30% more fuel). I'm going into it with the idea of making it capable of 1,200 hp at the crank.
I'm not sure, but I think it will be one of a kind.

We have(had) a guy on the forum (Biggest) who built a larger displacement Whipple truck that was pushing ~ 800 at the rear. If you're still looking for input you could check with him on his fuel system.

I also know Livernois has done a few 6.6 Whipple and also 6.6 twin turbo trucks. They are pretty active on the forum.
Have. I’m still alive!
