Truth about nitrous effects on pistons.
Truth about nitrous effects on pistons. Hey, I have a pretty general question... I've browsed the stickies and searched but couldn't really find anything.
I know that under correct timing, CR, AFR, tune, etc a turbo car's pistons can last very long, won't slowly tear them apart. Is this true for nitrous? From my understanding, nitrous is basically just oxygen, basically a chemical turbo? But it's a violent reaction.. So can you set, for example, an ls2 goat up with a 150 shot and it not slowly develop holes in your pistons? or is there simply no way around it with nitrous.
Thanks,
Ricky

I also have read post after post on the same subject before I got a kit.. I've learned is really about risk vs reward. Smaller shots activated at proper RPMs with proper electronic safe guards=lower risk. The bigger the shot at lower RPMs=higher risk. Seems like multiple factors go into the actual risk of failure. Devices can fail, engine physicaly can't handle the shot, A/F problems(lean or rich), but most common is a bad tune with 2 big of a shot. I just keep reading and learn something new everyday.
And on that note, its not just nitrous that hurts pistons. You can blow an NA motor up with the wrong tune, a stock crate engine with the wrong tune. All piston related.
We have a dipshit at work that preeches dope destroys pistons and its stupid to run it on/in your car. There is no arguing with his old bastage *** either becuase he is ignorant to understand the real affects.

[QUOTE=Obsidiansixer;13371057]So running a 150shot can be done on an LS2 reliably. Very cool. I have alot to learn, but that's great to hear.
The best part is you can drive all day NA putting very little stress on equipment. Then with the flick of a switch and with the proper electronics you can spray the crap out of it safley!!

yes with the proper tune up and equipment you shouldnt have a problem. Ive been spraying my SS with a 150 wet kit since 58k and now it just rolled 136k. No problems with it at all except tires and a clutch now and then. LOL
I run a progressive on one of my cars, it makes almost 800 rwhp. So on the street, or a crappy track, it's nice to be able to launch the car at a lower percent & allow it to ramp to prevent tire spin.
prolly later down the road im a get a progressive when i go into bigger shot range

its best to run a smart system if you are new to the game, bottle pressure and the temp out side will efect everything, the longer ur in it the more you want to meet ur piston in person, i dont want this to turn into another brand fight but a zex kit it u dont plan on going over 150 is a great system. bottle heater is not the best but it is safe, a heater with a pressure switch is best, takes zex forever to get up to temp. but the system will adjust is you are ever lower on the pressure. I noticed somthing thow.... ur pic shows a turbo system???? i hope u know if that is the same car ur gana juice then,,,,, yea.... maybe a diferent car, but if it aint then you may want to rethink this. A major tune will have to be done to keep that together.
Lol, thats my turbo V6. Almost done btw!!!! 
Hoping for 550rwhp & 10's. :]
I DD a 320k mile 1998 firebird. Lol, it's falling apart, I need a new DD. It's gonna be LSX. bolt ons and 150shot is the setup I was gaining for.

I used to go through a 15lb bottle every week. That got expensive.
Some basic rules of thumb on Nitrous:
1. Retard ignition timing by 4-8 degrees (1 to 1-1/2 degrees timing retard per 50 HP gain)
2. Be safe and use better fuel on nitrous. Anything above say 125 shot use some 100octane to be safe. I used 125 on pump gas all the time with no issues
3. Don't user nitrous for more then say 15 seconds. Nitrous creates increased cylinder pressures which caused a lot of heat. With lots of heat you can cause pre-ignition or worse full detonation. The longer you keep the juice on the hotter the motor gets until things are glowing red hot and you jump into full detonation and KABOOM!
4. The hypereutectic pistons that come stock in a lot of cars are really hard and don't like detonation at all. They aren't forgiving at all will shatter if full detonation occurs.
5. Check your spark plugs often and consider a colder plug.
6. Nitrous should only be eneabled above a certain RPM (say 3000) make sure you have an RPM switch to enable it. Having nitrous backup into your intake can cause a nasty bang. A guys hood almost landed on my car once on a drag strip run due to that.
7. Nitrous tends to shock your drivetrain. Make sure you have the hardware to handle the power.
I went Turbo because I loved the power all the time and it seemed like I was running out of it way too often.
Make sure you have a Fire Extinguisher handy also.

I always thought it was the fuel that was puddling on the intake. If for example you didn't purge your nitrous and it had air in it. You're putting lots of fuel in there with no nitrous. Or if you bog the motor you could also cause fuel to puddle in there.

You should post your v6 buildup in the FI section if you havent and get some pictures too, now there is a good thread to start...
