Default how much NA power can 255 pump handle with e85

Best thing I've found so far is a page that compared a few fuel pumps. It says a walbro 255 can handle 704 NA hp, but thats at 43.5 psi. I'm running 60psi so any idea how much it can handle at 60psi NA

I was told by someone from walbro not to run a 255 on ethanol because they are not designed for it. They make a specific 400 and some odd liter per hour pump that is made out of a different material internally. Yes you can run a 255 and it could last a month or two years but to me its not worth the gamble of ruining a motor because of pressure loss.

test N/A BSFC is overly optimistic, turbo BSFC is suspect too, they also don't disclose any info on boost levels for their hp estimates. I would take that data with a grain of salt
