Single walbro 450 with a boost a pump e85 what an it support
#22
I ran a 255 with BAP on E85 to 550rwhp. Factory feed and return, 58 psi base, and 8 psi. I think a 450 can go further, but the amp draw is much higher, which may burn up the BAP. I called KB and they didn't recommend anything more than the AEM320 pump with their BAP.
2 pumps would be better.

amp draw on the 2 450s at full tilt is huge, probably close to 40 amps. Took a couple highway runs for me to figure out the dimming going on when my front end lifted up was due to the pull from the 2nd 450 kicking on..

Sub'ing as this is the exact setup I'll be running. ID1000, F90000267, stock 05 bucket, -8AN feed / -6AN return, Holley rails, Racetronix hotwire kit, KB BAP. My tuner here in SoCal has said he has used the F90000267 + BAP combo many times with success, so we'll see.
