i've always heard that a 50 shot was about all that you wanted to run,

my tune is pretty safe i think, 11.5 a/f and 16 deg timing.

just curious if people have had success running more on a stock motor for long periods of time, or if that is pretty much it?

 

I would think a 75 we be fine if you had the tune, plugs, and fuel to support it.

Each motor is different for sure... Some could handle more some less....

50-75 hp isnt going to hurt much though unless its used wrong...

 

if you wanted more power, do you think go more aggressive with the tune or go 75 shot and keep low 11 a/f and low timing?
