Octane boosters are a load of shiat. You might as well pour paint thinner in your tank. Same stuff, only cheaper and without the catchy bottle.
I mix race gas as stated above. I've been using 30% race/70% pump for four seasons and haven't had a problem yet. Plus it smells good when it burns !
You're spending considerable $$$ and lots of time building your engine, it's be a real bummer to see you cheap out on the fuel and burn it down!
EXACTLY. If you are going to run pump gas, run pump gas, you cannot cheat. If you are going to run racing fuel, run racing fuel...
