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?

 

Yes, I was running the 40 amp/17 volt BAP with a Racetronix harness. It took me to about 670 rwhp on E85. I think I could have stretched it to 700rwhp, but not much further than that.

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.

 

I think it would be best to go twin pumps, one pump with a BAP on E85 will be difficult.

 

Yep. I ordred an aem external pump, sump, filter, and all the other stuff. My under the truck spin on fuel filter housing is dual inlet, so should be easy!

 

 

I will try to find the part number for the spin on filter housing if that is what you are talking about? It is a napa stock part.
