As far as race gas goes VP C16 is a middle weight fuel with respect to specific gravity. What that means is that it can support a bit more HP than comparable pump gas especially pump gas that has 10% ethanol (most premium fuels). Also that 624 number I am sure is a max effort. That is just way high. I know that he modifies the walbro pumps to work better at higher pressures, but still that is a very high number. It is not the average, just so you know. Still 710\>624 and 690\>624 so something is NOT right with that J&S dyno. --- _[View the full topic](https://forums.speedlife.net/t/first-700whp-tune/205049)._
