beebs Posted January 15, 2011 Report Posted January 15, 2011 (edited) I read alot about using 110 race gas, meaning it has 110 octane correct? I'm looking for a good 110 race gas and I can get VP-110 or VP-C12 in my area. I looked at the .vpracingfuels. web site and they rate the 110@ 107 "motor octane" and the C-12@ 108 "motor octane". I searched further and it looks like there are a couple different ways they rate fuels, motor octane and pump octane. So the 110 is 107 motor octane and 110 pump octane:(apparently the average of two diff ratings) and C-12 is 108 motor octane and 112 pump octane. My question is are these your typical 110 race fuels or equivilant, everyone talks about? Edited January 15, 2011 by beebs Quote

beebs Posted January 15, 2011 Author Report Posted January 15, 2011 So VP-110 and VP C-12 would be classed as 110 race fuels? Quote
KlotzBanshee Posted January 15, 2011 Report Posted January 15, 2011 The VP C12 is a great fuel to run in a banshee, question is do you really need to run it? For one its very expensive. And unless you are running high compression and advanced timming it will not worth the price you'll pay and will actually hurt performance. You don't need to even consider running race fuel untill you get over 160 ish psi per cylinder. *I have just over 165 psi per cyl (19cc domes @ 1000 ft asl) and +4 timming and run a 50/50 mix of VP C12 and premium 93 octane as recomended buy my engine builder (Jeff at FAST). Oh and yes, C12 would be 110.5 R+M/2 octane Quote
