i am asking because i feel 150 maybe 200 should be fine have bigger injectors and a boostapump, the reason I'm asking is because my friend got his car back with number seven cracked and some pieces out of the piston and there is some bowl damage on the head, nicks. this was done on the dyno by the tuner, the shop who basically installed it, and tuned it

With the timing backed out of the car for the nitrous it was making about 480 on motor. It picked up 145 on a 150 shot with the Nitrous Outlet Plate.

OK that explains it, so please can anyone tell me why the piston cracked, detonation low octane, wrong heat range of plug, a lean condition, bad noid, bad tune, what

When things break it can be from something as simple as a weak part to wrong plug choice, running out of fuel, to much timing, and on and on....
I have a local that lost number 7 on his Trans Am and it was nothing more than a heads and cam naturally asperated engine.

Hard to say with out all the details.. There are so many different varables that come into play with out all the details it would be nothing more than speculation.

lol, I know it sounds funny but it is possible.. But facts always work better than speculation.
What plug was being used?
How much timing was being pulled?
What grade gas?
I see the airfuel graph and nothing there would have hurt it..
Also lets say tune up was dead on. Has anyone else ever tuned on the car before this? If so, is there a posibility the tune was off. Or was parts added and it needed tuned but it was driven with out a tune? Pre ignition and detonation over a period of time due to an overly aggressive tune or a poor tune up will eventally cause parts failure as well.
Again lots of varables. Need alot more information..

he didnt know better some bad tunes times and rears blowing, and wait time, he was happy with the last one till the cracked piston
If the nitrous tune was correct and not an issue in the failure that resulted there is a posibility that one of the prior tune ups caused an issue that raised it's ugly head once the added cylinder pressure was introduced from the nitrous. Goes with the saying adding more power allways finds the week points..
I once bought a car from a guy that had zaped all the plugs in the car. He had done a compression test and leak down and everything showed to be ok. I put the car on the dyno and fixed the tune up, took it to the track and made 3 great passes. Took it home and a month later it sent a rod out the block cruising at 15mph through a school zone. Only thing I can figure is that when he killed all those spark plugs the detonation bent a rod and created a weak point that eventually let go.
