Over-Riding The Blow Off Valve On A L67
On the ALCAN, 98% of the time, Premo is not available; only 87 , so I want to manually leave the blow-off valve fully open for the trip to WCBF. I don't want to damage anything, just a temp setup that I can use on the way down theer and back.
Most over-the-counter octane boosters raise the octane by one point. POINT ONE. From 87 to 87.1, which is a ridiculous expense for next to nothing. It'* cheaper to buy the better gas or stay out of the boost.
BW...how much toulene does it take to raise 18 gallons of fuel from say 87 octane to 91-93 octane?
15 gallons of 87 octane pump gas and 2 gallons of Toluene will net 91 octane. So it'* going to be almost $30 for the Toluene alone, plus around $40 for the fuel? Wow. I think I'd rather just tell myself to limit boost to 5psi by foot-regulation.
