Nate1647545505 Posted April 29, 2009 Report Share Posted April 29, 2009 While we are somewhat on the subject, what is a good octane booster that i can get locally? Toluene, but, the shit is nasty. Be carefull using it and take proper precautions if you decide to go that route. Honda used Toluene in early F1, mixed with a bit of heptane (RON of 0) to stay 102 RON legal.
