Nitrous

Having a BP is good insurance, BUT i know of many running small shots on stock type converters with no issues, they have made several passes too, as long as its in good condition it should be fine, Now PTC installs BPs on all there converters now & the prices didn't go up much, this is what i was told when i had them build me one last year.

agreed you can get away with "small" shots, for "several" passes..but several isn't 20....and small isn't a 150 shot...i'm unfamiliar with PTC but if they are a top end converter like a ATI then i'm sure it'd be fine assuming they're billet and new components...but for sure..a cheap $200 B&M, after 10-20, 125 shots..will eventually go..now this also depends on where the shot comes, off the line is much harder on components than the guys that run a sneaky pete system to play the top end..it's the instand torque of nitrous off the line that baloons the internals and cause stress and failure, when under N/A acceleration the converter can "slowly" spin up with the motors smaller horsepower that it would have at say...2000 RPM's on launch...throw 200 instant ft lbs of torque into a torque curve at 1500 RMP and eventually...boom...trust me, words of wisdom here
