Re: 75 shot of n20 on a 150 black max
IF, and notice that is in caps, IF you mange to add enough fuel with the NOS that you don't melt the pistons, you still may grenade the motor. Rods can only spin so fast before exiting the block, the prop is the RPM limiter, bumping up the power without making a prop change can over-rev the motor in a heart-beat. Running with a larger prop (for the NOS) excessively loads the motor, radically shortening its life, and the motor won't accelerate til you hit the switch. Dump in NOS at low RPM and grenade the motor.
Not recommended.
