How spray can you put on a stock block of a mach 1 with out having any problems.

 

I would stick to a 125 shot at most with everything stock.

 

a rule of thumb to go by is your HP /2

 

125 is the number you hear a lot as being the max over on the registry. Some people can run 150 for a while with no problems, but you're pretty much on borrowed time with the stock bottom, even with a great tune. I plan on running a 100 shot once my rear is built. If need be, i'll bump it up to the 125.
