    Anyone tried N2O?

    Just throwing this out there since this forums seems to be more active these days... I came across this Zex nitrous kit for the 3.6 DI camaro, which I'm assuming wouldn't be too hard to adapt to our cars.

    http://www.zex.com/zx/2010-v6-camaro...us-system.html

    The guys on the camaro5 forums seem to be going really fast on these so I was just wondering why no one seems to be giving it much thought on our forum. Personally if I was in the market for forced induction on my CTS I would consider a nitrous kit long before a turbo kit or supecharger... It's easy HP... And if done right can be very safe as well. Also dirt cheap as you can see.

    From skimming through the instructions it looks like a nice quality wet kit. Looks like you won't need many other extras besides the colder spark plugs and they recommend pulling timing depending on how big of a shot you go (2 deg. per 50 hp). You can either do this by an aftermarket ignition box, or having a custom nitrous tune in the ECM, but the ignition box is more practical imo since you can also wire it in as a RPM window switch for the nitrous (The instructions say not to use it below 2500 RPM) A bottle heater would probably be a good idea as well to maintain stable bottle pressure.

    What do you guys think?

    Re: Anyone tried N2O?

    You might be onto something here ... but frankly, I think the reason you haven't seen much talk of nitrous in the forums is due to the vast majority of us using these as predominantly "daily driver" cars. I know personally, I'd find a (properly designed) supercharger or even turbo kit to be a little more practical to boost my CTS's power for regular use. After all, how many cars have you seen sold from the factory as turbos or with superchargers, and how many have you seen with nitrous?

    Nitrous is a good, cheap way to gain HP -- but it's inconvenient because you have to worry about refilling the bottle and it taking up space in areas besides just the engine compartment. Secondarily, I'd always have at least a little concern that you're just one defective window switch away from blowing the engine when using it. It's safe as long as everything functions like it's supposed to ....

    Those are some good points... I agree with some but disagree on others.

    On maintaining daily drivability I see what you mean but nitrous is actually more ideal than turbo/sc imo in the sense that 99% of the time even though the car is equipped with n2o, it is not in use. Other forms of forced induction are on 100% of the time and although fine you won't see full boost very often, the parts are there and operating all the time and they need to be maintained and it's only a matter of time/mileage before turbos and s/c head units need to be rebuilt. But for a weekend warrior nitrous is a better choice again just my opinion. And in the case of the 3.6 it would be better since it is a high compression motor which is not ideal for boost but ideal for n2o.


    As for taking up space you are right the bottle does take up room although there are plenty of creative ways to hide the bottle and the other components, mainly the lines, solenoids and nozzles can be hidden such that the install can sometimes be almost completely stealth... especially with the CTS and all those plastic covers under the hood

    the disadvantages are of course that the bottle must be refilled which is a pain and costs money... And as you mentioned sometimes componenents do fail... One of the more common things (hapenned to 2 of my friends) is an intake backfire, which happens when nitrous/fuel mixture is introduced at too low RPM it will backfire through the intake, but even then you are only a intake and MAF sensor away from evertyhing being back to normal. What hapenned to my buddies is that in both cases they got a bad nitrous fill, debris got stuck in the nitrous solenoid which in turn remained stuck open.. as the throttle body blades closed, nitrous flow to the motor continued... When they got back on the throttle KABOOM!! LOL Scary but pretty harmless. I learned from their mistake and bought a nitrous filter for my nitrous kit on my camaro

    The other thing is its pretty much for running quarters or other forms of drag racing. Most cts owners aren't gonna be doing much of that. if I really wanted that much power, I would have bought a V.

    Re: Anyone tried N2O?

    I just can't wrap my head around the fact that people here are willing to spend 400-500$ on an intake that might give you 10 peak horsepower but no one wants 75 or 125 hp for a couple of hundred bucks more... Especially with all this talk about turbo/superchargers which people are ready and willing to shell out 6 grand for... On top of which the turbo and supercharger kits as of now have yet to produce proven results, whereas guys on the camaro forums have cracked 11's on the quarter mile with n2o already with the 3.6!!

    Like I said if I didn't already have another car for summer which already has nitrous installed on it I would probably be looking into getting a nitrous kit for my coupe. It's so tempting I may just eventually go ahead and do it anyways

    Re: Anyone tried N2O?

    Well, I for one am *not* willing to shell out $400-500 for an air intake. If you read the stories from all the people who upgraded theirs, they're having issues with whistling sounds they're making too. I'm not willing to put on aftermarket parts that ruin the quiet, elegant type of ride you get from a Cadillac.... especially for an unproven, debatable 10 peak HP (may only happen in combination with other specific modifications and when the weather conditions are just right). I'm keeping my stock intake in place for the time being.

    On the other hand? I was willing to spend $400 or so for the Trifecta custom tune, because that seemed to add a lot of value (simply changing the auto transmission's shift points was worth the cost, really -- and then it opens the door to other benefits, like retuning in the future to optimize the car for other changes you might make).

    If I was someone who was serious about bolting on a supercharger for $6,000, then yeah -- I'd also give nitrous some thought. If you go ahead and add it to your CTS, I'd definitely like to see pics and any details of the results it gave you. I think right now, nitrous is just as "untested" on a CTS as anything else though? If you're going by the Camaro guys' results, that's helpful info but not the same as saying, "I already put it on my CTS, and here are the exact parts you need (with part numbers and prices), and here is where you'd bolt all of them down so they fit nicely in the engine bay."

    I mean, even with something as simple as an oil catch can, Camaro guys were doing it for a long time on their 3.6DI engines before someone came over to these forums, pointed out the advantages, and explained exactly how and where you'd bolt it up, attach the hoses, etc. All of a sudden, they started selling a bunch of them to CTS owners.
