how good are speed pro pistons? can they handle a 150 shot of n2o without a problem? should i look into a better piston like a srp?

Used them for 5 years in my 468. they liked their life and are now RIP. But still nothing wrong with them. 300 shot no problem with my 11 cr

guess thats what im getting then.

Cooool.....I just bought a set also. graemlins/thumbsup.gif
