I have a stock LS3 with a K&N intake, 5000 miles on it, I want to get a tune and have Nitrous installed but want to get some feed back, can i expect some good gains? What should i expect to pay? Is a 150 shot ok? Any feed back would be great. Thanks, Travis

 

What you expect to pay will be determined on what kit you get. For a full kit with basic safety features expect to pay around 800-1200 bucks (of course it can be more than this depending on what all you want to add onto it).

Nothing beats the gains that nitrous offers....nothing.

As long as your tune is correct a 150 shot will be ok.

 

I'd suggest taking a look at these pictures before deciding anything:

That's all there is left of my friend's 2008 LS3 after a shop didn't set up his nitrous correctly and what's even more scary is that it was a very small shot, either 50 or 75.

I do know that when it's set up properly it can be a great mod but as with anything else, there are definitely downsides to doing it.

 

Tuning is everything when it comes to running NOS

 

With a wet kit (and window swith so that nitrous flows only on WOT), don't the nozzles act as the tuning. In other words, you add the nitrous (more oxygen) and gas via nozzle size. So what else needs to be addressed in a tune? I know little about tuning so this is a serious question. I am guessing timing may need to be retarded a bit to be safe. Anything else?

BTW - I have no plans to use nitrous, but am curious.

 

I added a single nozzle to my LS7, 75 shot jets. I got 95whp and 150 torque. Nothing else changed, No tuning adjustment. Just put it on a dyno to check air/fuel ratio. No issues to date.

 

That looks more like a valve,keepers,or a spring broke than a NOS problem?

 

do it! but you'll have more $ than just the kit into safety items. get a good dyno tune

 

I was thinking about doing a 75 shot what kit are you running? Great numbers out of a 75 shot..I've heard they produce more...

 

Was thinking the same.....it looks like he fragged an entire PISTON in one of those shots. That doesn't look like the result of a 75 shot.

Unless he did something like sit on the rev limiter on the hit until something in the valvetrain just gave up and all hell broke loose, I don't think that was tuning. That looks like a mechanical failure or failure or absence of a safety feature that caused a mechanical failure.

Typical safety features (WOT switch, window switch, fuel pressure safety switch etc) are pretty good at preventing that kind of carnage on shots way bigger than 75.

 

If you'd like to contact me here at the shop i'd be more than happy to go over any concerns or questions so when you are ready you have a good handle on what is needed. 866-648-7637

 

I am using a single fogger nozzle. It is one from an old TNT LS1 kit. Very simple and effective power adder.

 

I'm running a Nitrous Outlet Plate Kit. 125shot with a little tweaking and some timing pulled and no issues as of yet. Just bought time on a stock clutch haha..

 

I have ran a 150 shot for about 9 months now on my car, no issues. The car HAULS on the spray. It made 650/700trq and then blew through the clutch on the next dyno. I pulled 8 degrees of timing out of the tune on pump gas and 6 degrees out on a 93/110 mix. BR7ES plugs gapped at .025. I had spark blowout with TR6's.

I have a NX wet kit with a 15lbs bottle, MSD window switch, shark nozzle, purge, bottle heater, and the Billet NX bottle brackets.

I am now putting a blower on the car and pulled the nitrous kit off.

Actually it's for sale if anyone is interested. I just haven't gotten around to posting it up yet.

 

Big turkey quick question did you upgrade the fuel system for them numbers?

 

I'm sure he has a Kenne Bell Boost a pump or something. Stock fuel system would not like that I don't think.

 

Hey man. PM me your price and everything that's included.

OP, I know many many people that run nitrous with no issues. It's all in the tune. They say 75-100 is normally fine with a stock computer, but when you start going bigger then you have to tune it. Hope it all works out for you.

Is that a bone stock LS3 with a 150shot or is that cams, bolt ons etc.

 

Having developed a perfectly safe dry shot, there is zero chance of a nitrous backfire using that format and my tuning method is 100%. Nitrous backfires (which accounts for All the pictures you see of blown up cars) were caused by:

Wet shot users who didnt tune properly
Wet shots fired too early in the RPM band such as out of the hole
Wet shots used without a window switch.
Wet shots that had a leaking fuel solenoid
Wet shots that were not tuned w/wideband flowing way too much fuel.
Wet shots.

Your intake manifold was not designed to flow a liquid. Its for air only. A backfire is from fuel puddling in the bottom of the intake that ignites. If you dont use a wet shot there is no fuel solenoid to leak or to fail to fire. You wont get a backfire.

If you want the truth about a proper set-up, read this thread:

Dry shots have all ups and no downs. The reason tuners dont want to set them up is that they dont know how to tune one and wet shots are easier for them. Dry shots power professional drag classes to victory.

What ever you choose be aware that a 100 shot is 225 rwtq unlike a supercharger that gets you 100HP with only 60RWtq. So when sizing what you think your tires will hold, look at TQ specs and not HP specs. a great protection is to use a nitrous control unit like the NOS one here:
http://www.jegs.com/InstallationInst.../741-15834.pdf
It ramps up power in a linear progression so you dont break traction (or flow too much fuel at a low RPM if you use a wet shot)

NEVER TAKE ADVICE ON A MOD FROM SOMEONE WHO DOESNT HAVE IT.

Having installed dry shots to perfection, I would never tell anyone a wet shot betters it in any way. Dry shot haters all speak about the difficulty of setting it up.....not its use.

I can post pictures of H/C installs that blew up and then say H/C packages are unstable and dangerous.....or maybe I can recognize that some installs are butchered and done wrong (installer error or using the wrong parts). A nitrous kit that blows up was installed wrong and used inherently dangerous parts like a fuel solenoid. ALL nitrous installs require a full tune and I dont care how many thousands say they didnt without fail. You count failures to get a failure rate not how many cars didnt blow up.

 

You can use a window switch to engage a parallel pump or BAP. Stand alone fuel systems are available for those who insist on a wet shot.
