Title: Head/cyl cooling Post by: kingsburgphil on August 07, 2019, 00:24:55 am [attachment=1]Regarding Reid vapor pressure and distillation temps. Which properties will cool heads/cyl’s best?
I have a choice of 10 Sunoco fuels and 4 Trick fuels, available locally by the gallon. The engine was jetted For VP C12, which ran perfect albeit hot. Some will recall I used E85, ran great till I moved to the PNW. I’m thinking a rvp of 5 would phase change in the upper cyl, rather than the manifold/head. Your thoughts?
