Contour Enthusiasts Group Archives Forums Modifications Forced Induction Here is what Nitrous did for me.

I could of course be talking out my a$$ but it would appear to me that there is metal left in the head from the plugs?

Man, that is painful to look at. I hope your motor is okay.

Brian-

Some of the plugs might have been going and could have caused the car to go lean. This leading to all the plugs self destructing. Do you have a chip burnt for your Venom? You might want to get a chip that can lean and rich the car whenever needed throughout the rpm's. Send your dyno plot to wherever you get or purchased your chip and they can calibrate it to the dyno. You need to redyno though so you can do an a/f ratio test as well. This is just my $.02, but what do I know? In my opinion it's deffinitely a fuel problem. From the dyno I saw it dropped bad after 6,000 rpm's. You like run really strong up to that point then bam you get hit by the wall. I wouldn't know where to start though. Maybe upgrading all fuel related shiznit. Like fuel pump, change fuel filter if havn't yet, bigger injectors, possibly a regulator, etc.... Bro I hope this is some advice. I am still tuning my Vortech. I told you before you bought this kit you will end up like me. You are going to have your ups and downs, but you said to me this is ok cause you have a beater. So I hope you are cool with everything. You have to start somewher you know. Later bud.

That looks like a clear cut case of detonation. That's why I'm either going all or nothing with my nitrous buildup....fuel, timing, nitrous, it all has to be balanced to get big gains without going boom. Looks to me like your Venom system dumped a bunch of nitrous into the cylinders. You sure your solenoid box is working properly? Weigh your nitrous tank...is it lighter than it should be? What mode were you in? It deeply concerns me that you were only running the kit at 5% and had this kind of failure as soon as you got out of your driveway. If it were me, I'd:

1. Check the wiring to all the fuel injector harnesses
2. go with a spark plug that's at least 2 heat ranges cooler and set the gap really small (like 0.035)
3. Get some way to have your timing retarded by 2-4*, maybe more, up towards the top end.
4. DEFINITELY change your fuel filter...it could be clogged causing a rapid leanout when fuel demand rises. Try and get a good aftermarket one if possible.

I hope you didn't burn a valve or worse. Please let us know what you find out buddy....if that system does nothing but eat spark plugs and burn pistons, I'm just going to buy a zex kit, wheels, tires and suspension instead of the Venom kit and fughetaboudit.

What would your N20 tank being light have to do with it?

Na that chit disintigrated(sp) I chip a piston in by old buick once and that disitigrated. It probly banged around for a while then was gone. I think your biggest problem will be head gaskets, aside for mthe obvious.

Do a compression check on each piston. I'd personally pull the heads off just to look and be positive, but a compression test should be enough.

And change your oil probly burned the piss out of it.

Well, if he had a full tank, and was only using 5 percent flow, and he only drove down his driveway, then one would figure that there wouldn't be very much nitrous gone from the tank, hence it would weigh about the same as it did when it was full.

But, if his hardware or processor is malfunctioning and dumping a lot of nitrous in (say, 80%) then the bottle would drain quite quickly and would be measurably lighter. Just trying to help offer ideas to try and troubleshoot the cause of the malfunction/meltdown.

Those are NGK V-power plugs right?I have those for my civic.they are copper internals.go to NGK's site and check out the plugs they have for your car.I can't believe it fried the plugs like that,sorry man,that totally sucks.

Looks like a fuel delivery issue, or lack thereof. I also agree with weighing the bottle, that will tell you about the 5% deal. Personally, I think it's a combination of things, there's no way that 5% flow did that much damage, and even then you'd still have to have a fuel delivery issue as well. Do not spray it again until you're sure you've found the problem. Do not use "special" plugs with nitrous, use standard plugs 1 to 2 heat ranges colder. Start out rich, and work towards lean, NEVER the other way around. Good luck.

Where those the same plugs you ran on the dyno? Or did you regap those since then and or replace?

Those look ummm well used

I would see if you can't get a OBDII scanner on your car on the dyno. From there we can pull some information. Thus we can see what we need to drop or raise in Fuel Pressure, Timing, Spark Curve, ect... That would help out alot!!!
