So I’m trying to figure out what fuel to run for the Dorch combo set up and I’ve asked Dorch for a details on their claimed 800 hp flow potential. Here’s what they had to say. Does anyone have insight or expertise. Is it ok to run vp110 race fuel on our engines with a proper tune?
“Realistically rating a HPFP by a singular power number is very much an over simplification so results can vary quite a bit depending on tuning strategy and turbo choice, etc. Our ratings are to display average results with proper tuning based not only on our in-house shop car Dynojet results, but also 3rd party tuner Dynojet results. Since these ratings are to display your power potential based on the flow capacity of the HPFP, gasoline will show a higher flow potential. This is due to E85 requiring about 30% more fuel volume to make the equivalent power as gasoline. So in other words if you were to compare E85 with a gasoline based fuel with equivalent octane rating (race fuel), you’re going to need a 30% larger fuel system to make the same power on E85 as you would on high octane gasoline. So to answer your question, this is a race fuel result. This is extremely uncommon due to the price and availability of something like this so customers most commonly run E50 as a happy medium. E50 typically ends up at 650whp for those trying to keep the stock transmission alive or more like 700-725whp at the limits of the DS25 HPFP.
