Racetronix says it in their comments that at 43.5 static pressure, 30psi boost it can support 900FWHP at 13.5 volts. I have to assume this is a petrol/gasoline rating. If so, I assume close to 600 FWHP at 13.5 volts. Has anybody tested this pump to its limits on a e85 turbo car? How far did you get? stock voltage or booster? Thanks!
