Hotwire, 450, BAP
2004 Silverado, running out of pump with Walbro 450, Racetronix hotwire, e85, and 13 psi. Anybody running a Kenne Bell 40a boost a pump with this pump and harness?

Depending on how much power you want to make, tt would be better to a return style conversion and dual pumps or maybe the new Walbro 525?

I did convert to a return style, -8, -6, regulator after the rails. With my trap speed and weight, I should be right at 600whp. I am thinking that's about max for this pump with e85. I saw a chart a while back that had the 267 pump with higher voltages and I can't find it now. Would like 750whp worth of pump.
