    I've used them. It's not usually the piston that is the problem it's the tune on the motor.

    How much boost you talking about. Most pump gas deals don't need a blower specific piston.
    A good 2618 forging like CP's Bullitt line with a pin upgrade is all you need, and they are cheaper. Same machining as CP's pro series pistons, same material, just a lot cheaper for a very nice piston,

    If its a race gas or alky deal, that's a different story. Still prefer CPs.

    Will be running about 6 to 8 lbs of boost and it will be on race gas.

    How big is the engine? I've ran CP Bullits at 10 with no problems with a pin up grade.

    We have them in our engine with tool steel rings. They are tough as nails. Been ran blow up lean and only killed the rings. Fuzzed one piston.

    You are right the max limit for pump gas with 8lbs and the compression the Diamond blower piston will make. But if you are in fact running 110 fuel, you might as well go ahead and run them. Chances are, you'll crank the boost up because the fuel will let you. You would kind have it both ways. You could slow the blower down for pump and crank it up for 110, and the pistons and pins are there to handle it.
