What size is the RCD IHI? I had a DTS billet 66 IHI and think I was about 650 with 45% over's and Exergy 10mm pump and I had plenty of fuel.

Here's a vid of my truck last summer. I actually broke a stock axle when I unlocked the converter at the end. Took 1st place out of 28 street trucks.

As much as I say I'm worried about this thing holding together, I'm not looking to be conservative with the tuning.

I can run dual pumps if this II 85% doesn't cut it.

Just put dual pumps on it from the beginning then, that way you can max the rail psi out. Lbz regs on both pumps? More rail psi you got the mo powa your gonna have.

No sense of tuning it conservatively, wouldn't you rather blow it up at its full potential, then blow it up at 75%?

I'm on a budget this year. I'm going to take a shot at just the single pump as there is one place I hook twice a year that won't allow the duals. If I find it lacking, Ill use my stock pump over the 85.

The River City charger ill be running is the big one with 2.5 cover.

A split ratio will suck some of your power, but its not foreign to pulling at all.

I know its not foreign to pulling. I realize its going to fight a little bit, but Am I on the right through process? Or pissing in the wind trying it at the HP range I'm shooting for?
