Bosch 237 regulator and e85?

I'm also going with Racetronix 450lph pump, 120 injectors and 6an return. I have the 237, just wondering if its going to be a weak link.

Dump the Racetronix pump and get a DW400 if you have the cash to, because the Walbro-based pumps lose about 30gph in fuel flow from 40 to 80psi. DW pumps lose about half that.. Arizona GN is a Deatschwerks vendor and could get you a DW pump.

To answer your question though, the 237 most likely wont be an issue if you're only putting 400-450lph of fuel through those lines...

Thanks. The pump was a tradeoff. I used their graphs for my calcs, but if they're bogus...

I may have it confused with another, in all fairness.

How much was the dropoff in fuel flow from 40psi to 80psi?

~100. From 430 to 328. They rate everything at 13.5v.
