Unleaded Race fuel? ex. torco, c16 etc?

[john3883]

I plan on doing a road trip next month and some of the stops may not have higher octane as in 97 / 98 octane. I can't use cheap octane booster and need proper stout/ stuff. It is a matter of detonating/blowing my motor not just running like crap( i can't take chances). I may look into getting a canister with few liters of this stuff to mix with the lower grade petrol.

Does anyone know where Torco or race fuel, C16 etc is availible? Hopefully near Silverstone where I live? cheers

keep out of boost?

VP stuff is on sale through Santa Pod Raceway or Motorshack at about £140 for a 5 US gallon drum.

Its gonna be hard to stay out of boost. I am doing Weekender with petrol heads nivarna? So i won't be able to wing it babying the throttle.

How much boost and what compression?
I'm putting 10 psi into a stock 350 chevy (albeit with ally heads) which has 9.25 compression - as long as the ignition is mapped correctly you shouldn't have a problem.
Modern chevy's (LS1/2/3) take boost and they run much higher compression ratios - again, you need to manage the timing.

One of the suppliers at the circuit will have some. Alternatively if you've got a container the petrol station there sells 102 octane.

I'm running 15 psi on 4.6 v8 4v. It is tuned for 97/98 octane and i can try to reduce the timing but i don't like to mess with tune much and risk hurting the motor. I have already had the engine pulled once and I can't afford it again.

Just remember that C16 is a leaded fuel - not suitable for road use.
However the barsts still charge road fuel duty on it.
