Gotti94 Posted January 26, 2020 Report Posted January 26, 2020 Build triple port exhaust 4mil stroker 35mm carbs cut domes 20cc domes vforce4 What gas should I run and does 110 have benefits over 93? Quote

trickedcarbine Posted January 28, 2020 Report Posted January 28, 2020 20cc domes put a 4mil stock cylinder motor in race gas territory. 93 will probably detonate. Keep the 20cc domes and give it 4 degrees of timing and feed it some 110. C12 or VP110 will keep it nice and happy. Race fuel typically benefits from being able to run higher compression and timing. Then you get in to oxygenated fuels and you see even greater potential. But just tossing race fuel in a motor built to run pump gas will actually make less power. Quote
ClaudeMachining Posted January 28, 2020 Report Posted January 28, 2020 Run the less octane that your setup can take. Too much octane is not benifical.Envoyé de mon SM-G965W en utilisant Tapatalk 1 Quote

What psi roughly would you say pump gas is at it’s max? Quote
Ayesully810 Posted January 29, 2020 Report Posted January 29, 2020 155 anymore you want closer to 100 oct Quote

Deets Posted January 31, 2020 Report Posted January 31, 2020 I’d think if I got smaller domes and cut the squish band down a bit to reduce squish velocity I could run higher psi on pump gas. But it most likely wouldn’t be worth the effort Quote
