Will the transmission hold up to a 20 hp shot? I don't plan on holding down the nos button very long, just a squirt here and there. Too afraid of melting piston. I was thinking I could use it under full throttle only and use a mild shot. Is 20 hp a mild shot? To me it doesn't sound like it... Do they make smaller jets for maybe 5 or 10 hp? Did you use this nos on a zilla?
