Nitrous 175 shot on stock engine?!?

They claim you can put upto a 175 jet into a stock engine, how?

sure you can do it.......once.

I would not put a 175 shot on a stock engine unless the engine was not mine.

I have thought about putting a small nitrous kit on my 66 stang. Maybe 50 - 75 shot. Assuming the fuel system was up to task and timing was limited, would this cause any problems with stock pistons?
Does anyone here have nitrous with cast or hyper pistons? If so how much?

I believe it..

1st off... contrary to popular belief, nitrous is no harder on the engine than any other modification that would increase horsepower. Of course, this is only if you ensure a proper tune.

So.. letse. A stock 289 makes what? 200FWHP? I think a stock 289 would be able to handle 375FWHP (approx 325RWHP) with little problems.

Also remember... we're using this stuff in 10 seconds spurts here.

I'm running the stock bottom end in my 351W (cast pistons and all). The engine was a recent stock rebuilt when I got it.. and when I bought my nitrous kit, I couldn't bring myself to rebuild a perfectly fine bottom end. I decided I'd hook up the N20 (Jetted at +150HP) and run it till it broke. That was 4 years and many bottles of N2O ago. The ole 351W is still running great and shows no sign of wear since the day I bought it.

Sweet!!! The bottom of my cleve is brand new too, I've got the speedpro cast? pistons with the teflon skirts!! I might have to add some juice

It may not hurt the pistons, but I've seen numerous pics of "hammered" rod bearings from it. And they will not show signs of anything out of the ordinary till you get a rod knock. By then, you've likely damaged the rods and crank.

Hammered bearings sound like too low of rpm. N2O flows the same at idle or 10,000rpm's. At low rpm's the cylinder gets much more per intake stroke. Killer torque, but not easy on rods or bearings.

Guess I should mention that I never activate the N2O until engine RPM is over 2500.

Seen guys run 250 shots on stock bottom ends. Total amount of HP is what will kill it. The more nitrous, the better the tune needs to be. One guy I met at the track was runnin 7.30's all day long with the 200 shot on a bone stock mustang.
