Damn that sucks, but that would be really cool to see.

 

Like CAT3 said, hurting a motor is just a good reason to get a better one. That's exactly what happend to me, even though I wasn't planning on it.

My story goes like this, I had just gotten my 95 T/A and installed a simple single nozzle system on it with the 150hp jets in it. Only modification to the car was a 4" Mufflex exhaust (installed before I bought the car). There was a local guy with a big ego that was talking about how quick his LS1 was (supposedly he had just dumped $10,000 into it). We decided to try a race one night with me on street tires, him on worn out drag radials, both of us spraying. I know it sounds like a bad race, but I actually won 1 out of the 3 races, lol (his car was a 6-speed at the time, and he missed gears quite often).

This race was followed a couple of weeks later by a trip to the 1/8 mile track in Denton so that we could both hook, and we would both be on ET Streets. Things were quite a bit different this time. I think we lined 'em up 3 or 4 times and I drug him everytime. The problem was that the car was picking up several tenths every pass and I couldn't figure out why. The plugs that I would pull after each pass looked good so I didn't think it was leaning out..........oh but did it ever, lol. On the fifth pass I brought the rpms up as high as the stock converter would allow and then I burried my foot in it when the tree came down. The car left like a scalded ape, and right as I was about to shift to second...........BOOM! As the car coasted to a stop I remember wondering how I was going to get to school and to work since this car was my daily driver, lol.

The result was the #4 piston disintegrated into metal shavings in the oil pan, the wrist pin was welded to the connecting rod and it punched a fist sized hole compeletly through the block. All caused by the little piston in the fuel solenoid swelling up and slowing cutting off the fuel supply when the system activated. ALWAYS CHECK YOUR SOLENOIDS.

The funny thing was that I already had another complete LT4 engine lined up to buy and put in the car as soon as I got back to town........but somehow that motor never made it into the car, and 1 1/2 yrs. later with over $15,000 spent (not including the hook-ups, lol) I ended up with a new rear end, new wheels and tires (slicks and skinnies), new drive shaft, sub frame connectors, converted to a TH400 w/ trans brake, light weight seats, gutted interior, and a very nasty little forged 383 LT4 that was begging to be sprayed, lol.

Then I sold the car for $5500......go figure, haha.

How's that for a story Charlie? lol.

 

i witnessed a 01 Cobra blow up on a dyno like 2 feet from me. He leaned out a lot. Bottle PSI was up way too much and he had a bad tune, Im pretty sure the timing was ADVANCED. Major engine damage. Bent valves, intke manifold blew into like 3 pieces, wiring and tubes melted, entire intake tract was blown up. Cost him well over 3K.

As long as you have it set up right and understand the operating parameters (RPM Window, bottle PSI, jetting, good fuel PSI) nitrous is completely safe. It is the people that ignore crucial setup steps that wind up with engine damage.

 

Here is a video of Nitrous Gone Bad!!!

Nitrous Gone Bad

 

yikes... now that is a horror story... that is what makes me scared... your leaving your motor in the hands of a lil solenoidand a couple electronics.

And to make it worse.. on the street you would never know that is going on wiht your fuel solenoid... yikes...


*runs and*(puts nitrous kit back into closet)**

 

the worst i've seen/heard of is the video of the yellow c5 zo6 spraying out of the hole (rumored to have left the tcs on) and having a nitrous backfire- then burning to the ground.

you play you pay

 

I blew the welds on my intake manifold... j/k
the only thing bad would have been the tranny starting to slip after about 20 bottles on the V6 spraying through the shifts on a A4... dumbass me

 

how did you spray threw then? didnt turn off the toggle switch while it was shifting?

 

Lots of people spray through shifts. The system is activated by the WOT switch so as long as the foot is on the floor and you are in the RPM window it will spray, even through shifts,

 

Myself, I have never hurt any motor, drivetrain yes. But, we will see if I can get a new ls7, as I try to push the limit of my stock ls6 250/300.

Here is a pic of a fellow Z06 owner who just posted on another site. A 200hp shot for two years (wet) and then boom (#2 piston). I think he also leaned out. With this new crappy gas with new crap being added, wet guys should be checking fuel noids more often.

Jeremy...thats awesome man. Thats the kind of **** that helps define our character in years to come.

 

Quoted because it is so true.....

 

Yea, until
a fuel noid fails,
a fuel pump fails,
a n2o noid sticks open,
and on, and on.
Even if a set-up is done properly there will always be the chance of mechanical failure.

Here's a horror story not an LS1 though

My cousin has a 2002 mustang gt. Me and another friend talked him into nitrous. I hooked it up for him since i've had nitrous on my 5.0 for years it wasn't to bad to hook it up. Now before he took it outta my driveway i warned him, i dunno how strong your motor is i dunno how it will react to the spray it's not a 5.0 so i can't tell you for sure. We should rejet it for a 75shot instead of the 100shot the kit was setup with. He declined i was like ok man whatever and i went through some of the safety precautions with him like spraying under 2500rpm so on and so on and don't spray in 5th with stock gearing and the crappy weak 4.6 interals.

Well not more then a week an a half later we're out having alittle fun with some friends with the cars. Well he lined up against an SRT-4 stage 2 w/toys that ran a 12.7-12.8. They start off at the bottom of 2nd what about 35-40mph and run all the way through 5th! Not just alittle into 5th, my cousin said his speedo we buried so he was well into 5th gear so what that's about 20-30 sec's of nitrous. Well as soon as he let off the motor gave out, knocking real loud. Amazingly enough it still ran how i dunno and after i tell ya the damage you'll wonder how it ran too. He bent all 4 rods on the drivers side of the motor, completely shattered the piston off the rod on the #8 piston, bent all 4 valves on the #6 piston. The 4 plugs on the drivers side looked like someone melted the ends of them off. But it would fire back up idle around 300rpm and sounded like hell lol.

A year and many many thousands of dollars later he has a new motor modular 5.0 with all this other happy crap. And he's deathly afraid of ever using nitrous again infact that nitrous kit now sits in his storage shed collecting dust never to be used again. Needless to say i think's he's going to be safer going with a S/C i tried to explain to him why he's old motor blew and he new one will too just as easily with a S/C if it's missused.

 

I had a huge backfire with my car. It destroyed an LS6 intake, bent the throttle shaft in the throttle body, and broke the #6 piston ringland off, which in turn scored the cylinder wall sleeve beyond repair. Also bent some of the valves in the heads.

This was all due to my own negligence in not getting all of the nitrous out of the intake before trying to re-start my motor after a nitrous solenoid stuck open. (Which was caused by a small pebble from the carpet of my car getting into the line and making its way to the solenoid, never again will I have an open line laying in my car without a filter between the open end of the line and the solenoid inlet.

$10k later, the car is back on the road.

 

That sucks.... my lines are just chilling right now.. but before i hook them up to the noids im going to open the bottle to purge the line of any debris. Hopefully we wil be good to go.

 

I've torn up **** but then again I have been using the gas since 1986. I went through allot of trial and error experimenting and such, and not always with good results. The one thing that I can say is that it was not the fault of N2O but more-so my own stupidity and or equipment failure. On the same note I have also torn up stuff with blowers and turbos as well. Anyone who states that they have not torn anything up despite having run their car hard for many years is either full of **** or someone I need to learn from. The fact of the matter is this - You will be fine so long as you pay attention to the issues related to maintenance and tune as well as keeping the N2O moderately sized to the motor in question. Don't be afraid of N2O, be afraid of the other fugger using it in the lane next to you.
