how common is it for a noid to stick? i want to run a 150 shot on my camaro but the whole nitrous just spraying in my motor when i dont have it on seems to be a problem with me.

run redundant solinoids. I run two at engine and one as the bottle opener, so when system is off I have three way protection and no chance of filling engine un wanted. When activated two n2o solinoids will eliminate the stuck open problem. I have had a dirty noid stick open before. Better safe than sorry.

but if one gets stuck it's going to leak into your motor while the other one holds it back if in a parallel setup unless you do it inline but then how will you know if it gets stuck?

Robert yours must be a dry set up right? This wouldn't really protect against a fuel noid sticking shut which seems to be the most common failure.

Ron, if you run a good filter and rebuilt your noids once a year you should be just fine. Seems more peole have problems with noids sticking shut than open(have heard about it acouple of times though). For extra protection you could also buy a Dyno Tune A/F ratio switch. These hook up to the O2 sensors and if the O2's take a major dive the nitrous system will be shut down.

Wet systems blow motors dry does not, think about it. So what if the fuel noid sticks shut computer will add the extra fuel, unless your running a real big shot (might run lean though). With back to back n20 noids you won't be adding n20 when you don't want to (had one stick open). If you have a n2o noid stick shut on a wet sys, good by motor and hood. there are exceptions to all the rules but this is the basics. Manifold was designed for dry only and fuel puddling has blown plenty of motors. You also need to check if a rebuild is in order once in awhile, even with filters.

First of all both wet and dry set ups will hurt motors. While smaller dry set ups have been proven to be safe, larger shots are notorious for running on the leaner side without a good nitrous tune and I have been through it myself when I got sick of a measley 100 shot. Secondly if a fuel noid sticks shut on a wet kit your fucked, the computer will not add any fuel since you are spraying beind the MAF. I've had one fail while running diagnostics and the O2s dropped to .050 (just alittle lean!). If the N2O noid did stick shut on a a wet kit (which is not very common) it is not a big deal, the car will bog and go rich but there will be no major puddling and no back fire as long as your above 3,000 rpm. LS1 and LS6 intakes flow fuel just fine, many TNT owners have sprayed 250+rwhp shot throught these intakes. Now if you tried spraying at a low rpm yes you can kiss your intake, MAF and lid good by. Both wet and dry setups are good if used and tuned correcly. However, in Rons case he wants to run a 150 shot and to do that with a dry set up he will probrably need to run to different tunes for the car, one N/A and one for the N20 or he'll have to settle with a super rich N/A tune. Now, if he went with a wet set up he could easily run a 150 shot on the factory tune.

GM Musle, You're right on the fuel noid sticks on wet your screwed, I stand corrected. But, on the n2o noid sticks you say no problem because your over 3000rpm, I not so sure there wouldn't be a problem. Ls1 an LS6 manifolds were designed by the engineers to be dry, that is why wet kits have puddling and hood removals. Check out the other sights as there is a thread going right now about guys running 200hp dry kits (more than a few) with no problems. If you have the injector size and proper tune 150hp dry is doable for sure. i am running a 125hp dry with stock tune and stock 28lb injectors, no lean problem and runs fine, this is were most guys get into trouble with dry kits: injector size VS hp shot. I'll see if I can find that thread. I wouldn't be afraid to run the 150 shot if I upsized my injectors and pulled a little timing.
edit: found thread on this sight from yesterday, check it out, good stuff.

Yea, one of our members is running a 2 stage 250 dry shot. I believe that he's running 10.8s with stock internals. I'm not sure how much tuning he had to so but maybe he'll see this thread.
