as much as you want ... all depends on how it was built... but .. i think quik will agree if your afriad to break it.. you never will drive it to its full potential..

with hyperutectic pistons I would say a max of 100 shot
with forged pistons, a 10,000 shot.
no, realistically, I wouldnt go over a 150 shot, unless you have a forged crank and forged I beam rods, then you could go till you split the block.

we need more info though, what heads, what other stuff are you running?

None, real men don't need any.
That stuff is VERY hard on motors, like the main/rod bearings......

Also is the rotating assembly stock? If so rebuild it w/ Eagle components if you want it to survive the juice.

Nitrous is hard on one thing.......the people that dont know how to tune it. I sprayed my car over 50 times. I just pulled out the motor to go through it. It looks like new. Back off your timing 4 degrees and make sure you have enough fuel going to it....I wouldnt go anymore than a 100shot. Make sure you get a WOT switch or a window switch. I am going with a supercharger because filling the bottle is costly and I want power all the time.

Off topic...What do you make on the 1/4 with all that?

tinman

That engine sounds fairly simalar to mine. Yep, you could spray it but I'd hold it down to 4# a minute if you must........
Just make sure there is fuel AND spark there for it........
