There are guys running HUGE shots of N2O thru these engines 250 HP +... w/dual, staged units.... the general rule of thumb is 125 HP on Hyperutectic Pistons, detonation free. Anything after that and it is a roll of the dice.... but many are doing it.

actually, our pistons are eutectic, according to all the specs I have seen, which differ just a little in the alloy percentages..... and it is true that many have used higher shots with no harm.... many more than have had failures... and there are a couple of them..... the best bet if you want to go very large shots is to use multiple stages, but the best idea is to install forged pistons w/a good forged aftermarket rod.... oh and a forged crank is not a bad idea either!!! H... tis only money!!

I have not really been keeping up with the forged piston availablility.... I do know that Federal Mogul has a Hyperutectic replacement that will be a small step up but I would not use it for N2O, I am thinking I have seen Ross Pistons in forged and there were at least 2 more companies in the works with them.... a little research should bring them to light....

You can use a SMT6 to back out some timing.
I can get forged pistons starting at about $800 (depends on how crazy you want the pistons) They are all custom made by one of the best piston companies in the country.
I sprayed a bone stock (well it has a flowmaster) truck with a 150 shot (stage 1 50 stage 2 100) with no problems.
Get the Zex kit, it's cheap, easy to install, and has lots of safety features built into it.
My bottle is currently behind the seat, but will be moving to the bed soon.

I built my NOS kit for under $350. Just awaiting install.
I don't like putting additives in my fuel, doesnt feel right. And the SMT-6 seems a little much for just some timing. If you said your spraying 2 stage on a stock truck, then I don't see a problem with mine.
Any tips you guys might have for us starting out with N20.

Well with nitrous if you play safe then no problems. If you start to tinker with the jets looking for more power beyond what the company says will work and is safe then you are playing with fire. It's true with most things, and especially true with nitrous, you get what you pay for. The more you spend on accessories (bottle heater, gauges, fuel pressure safety switch) the safe you are and the better your system will work.
The octane boosters work, and if you want to spray big (say more than 100-125) then use them, or UNLEADED race gas mixed with 93 octane. NEVER spray a hemi truck running anything less than 93 octane. These motors run on the edge of detonation already and nitrous can make that worse if you run cheap gas. ALWAYS run your superchips on "stock" or 87 tune. (The 87 tune actually retards timing which is a good thing on spray).
You should always run the NGK 4306 plugs. Don't run the iridiums, the bosch +2+3+4+10's or splitfires or ANY other plug. Gap the plugs to .035 or .040
Always run a wideband A/F guage too. Try and keep you A/F no higher than 13.0 and 12.5-12.0 is good on the nitrous. Too lean and you have problems.
Nitrous is great stuff, buy a good quality kit from a good company and follow the directions. Don't listen when the internet guys tell you to "change your jets to XX and XX" without calling the company who made your kit to see if it's ok on their system. Different companies use different jets and they are NOT the same.
The only drawback is when you have a problem, the damage will usually be done before you can see. hear or feel it, and it's usually expensive to fix.

Yes I hit a bone stock truck with a 150 shot (and 200) 2 staged no problems, however I don't reccomend it. I happen to have a couple extra motors around the shop and a killer motor being built so if I hurt one then it's really no big deal. I did it more to prove it could be done, not that it should be done. My new motor I am going to spray untill the coil packs can't light it anymore then back it off a hair, but it also has the best in forged motor parts so it will put up with that.
