Does anyone on here have or ever thought of doing a nitrous setup on their hhr? I have been thinking about this for a while now and and Im curious to see how its setup and if they even make a kit for the hhr, if you have any pics of the setup please post em...

 

you can do it man. LIke a 75 wetshot would be perfect

 

Give this thread a read, maybe you'll get some good info from it.

man Mike, reading that thread makes me want to get a 75 shot wet kit.

 

Fastest way to kill an engine is nitrous. I wouldn't, but it's your car!

Actually pouring drain-o would kill it faster (saw that on Mythbusters)

 

Here is RUDEINC's setup (type nitrous in the search function and you will find many threads):

 

If you're talking a "dry" system I'll agree with that statement. However, a well thought out "wet" system with appropriate ignition/fuel tuning and obviously within the mechanical limits of the driveline is perfectly doable. I'd throw a 75 wet kit on my SS with correct igntion timing and never blink an eye. Of course my clutch/tranny would be an immediate weak link but the engine wouldn't concern me. I've spent alot of time both building engines and working with tuners for nitrous (many in street cars) and never had a nitrous failure (wet kit). Only failure I've seen from a customer was a fella that had a late-model Mustang GT literally blow the intake manifold off the engine but that's a common thing with the plastic intake (if igntion isn't spot on). I have personally known someone running a 100 wet shot on a Mitsubishi G54b (Starion/Conquest turbo block) that is fairly easy to pop unless you're careful and he's been spraying for at least 3 years on a stock bottom-end. And I mean spraying pretty much daily

 

Just looked at your profile and noticed you have an SS. Here is a thread with some talk about it: https://www.chevyhhr.net/forums/show...hlight=nitrous

 

Nothing wrong with NOS as long as you do it right. Also the second part is to make sure if something does go wrong you can afford the results.

Many people use NOS with no ill effects and make good power. The key is to make sure to keep the system tuned and in proper working condition. Too often people either set it up poorly or fail to maintain the system properly and end up running lean.

Some also try to put a system on a beyond the ability of the enginer.

The long and short of it is done right NOS works with no ill effects.

I really don't see the need in a daily driver but it is fine in a play car. Also if something did happen it is best it is not the primary car.

Here is some trivia. GM had considered adding a NOS system to the Monte Carlo SS back in the 80's. It got nicked because of the risk of liability of a pressure tank in the trunk. GM lawyers did not want to deal with the possible cases and killed the idea.

I am more for doing power on engine but if you want NOS there is nothing wrong if you do it right and are willing to accept any issues if the remote chance one happens.

 

That's what I meant. So many people do it wrong. If you do it right, no problem. But like hyper said, I wouldn't want to risk it in a DD.
