87 octane!! help
Hi,
I need help with some numbers about the octane rating that my WI should increase.. I have a 1/4 mile race this weekend and unfortunately there is no high octane Gas higher than 87, yeah no more than that... I was wondering how much does the WI would increase my octane ratings with a 80/20 Water Meth injection and a M5 Nozzle on a RB26DETT. Thanks |

87 octane is a difficult one to estimate because not many people use it. I take a guess, W80/M20 at 10% W/F ratio will probably raise a 1 to 2 points. If you can 50:50, at 20% W/F ratio, you can gain around 4 octane point.
To work out W/F ratio, divide M5 by the total flow of all your injectors I cannot work out the flow of the M5 until I know your fluid pressure.
