Is race gas necessary for a 150 shot? Mods are in sig. I plan to run 22 degrees of timing and 93 octane. What do you think?

 

No, but it's a good idea if you're on a stock bottom end IMO. I run a 93/100 mix in my car on the 150 hit.

I'm not sure what you mean by "race gas" though... 100 octane? 110? C16?

 

i really dont consider 100 octane race gas since you can buy it at the pump but i guess some might..

 

no but its a good idea, get th stand alone fuel system and put 112 in the fuel cell.

 

I run 150 with 22-24 degrees...cant remember, and mines fun. But as the others said, it IS a good idea

 

+1 here. Get the stand alone and run 112 in it. That way you can keep 93 in the tank. You also won't waste the 112 being that it will only get used while you're shootin' the nitrous. It's alot safer, and you won't waste 112, which isn't exactly cheap anymore.

 

so the consensus here is YES!

 

cheap insurance man. you don't want a detonation because you got a bad fill up on pump gas. I say spend 50 bucks on 5 gallons of 105 unleaded and save yourself a potential 5000$ motor replacement. Make sure the fuel you run is unleaded. You run leaded you'll be replacing your O2's quit often.

 

depends, stock motor, built motor, compression, what type of kit, what rpm do you want to start spraying at?

Personally I do run race fuel, but I'm on a 13.5 to 1 motor, and would be running it anyway.

With a stock shortblock, as long as there's no cats on the car I would still put a gallon or 2 in the tank, unless you're on a standalone in that case put the highest octane in that you can, too much octane doesn't hurt stuff, only too low.
