My guess is that you'd need to add at least three gallons of VP100 to every 17 gallon tank of fuel to make 18psi safe (14 gallons of 93, with 3 gallons of VP100). To be sure, watch the voltage on your 2jz-gte's oem knock sensors. Ideally, data-log them against boost - first using straight 93, and then using various blends of 93 and VP100 to determine the ideal mix for the boost level you want to run. Note: Off-the-shelf octane boosters don't work. When they say "raise your octane by one point", they mean 93->93.1 ...NOT 93->94. Another option is a good methanol injection system. It's a bit more complex to install (vs. simply dumping some race fuel in your tank), it's but much more convenient in the long run.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners. Last edited by pwpanas; 02-16-2012 at 03:13 PM. |
