Anyone run nitrous on their Gen5

I am seeing knock with the stock tune and pump gas, so wondering how a 100 wet shot would do on a gen5?

Guess it would really need a good tune to be safe even with a 100.

The timing in the stock programming appears to be really aggressive. Fix that and you should be fine.

Check with CamaroGirl5, blackflag, she runs a 100 shot. The car runs mid 11s on the funny fumes.

You should pull at least 2 degrees of timing for every 50 hp of nitrous and go from there. I am planning on running the lingenfelter timing controller, but there are others out there. Its either that or reflash ecm every time you race.

I'm not a big fan of the MSD timing twister or the lingenfelter box. Had some issues on my 98 with one. I'd rather just pull timing in the tune.

Just saying that since the stock timing is so high and it gets KR and pulls some, that one would have to pull more than the standard 4 degrees on the stock tune-up. Probably 6-7 degrees to keep away from detonation and having the motor pull even more timing.

Race gas will help as well. There is a gas station here in BG that sells 104 octane at the pump if u need to gas up before heading to Beech Bend

True. The way my custom tune is now, with knock sensors at stock settings I am getting zero KR at WOT.

Nice! Sounds like a real good tune up. I made a couple hundred passes in my ls1 on the spray before I had any problems. Was grudge racing one night and reached back and turned the bottle on after my burnout but didnt check the pressure. Well it was 1300 Ran good for 30-40 feet before a gnarly backfire and got a rod.

Went through the entire car and building the motor this week. Taking the nitrous out for a while so I'm not tempted lol

Oh wow that is a bummer to hear!
That is the thing I fear about Nitrous, with my luck it is bound to happen lol

I had slightly adjusted the bottle heater in the pits and though it was on 950 (being a little greedy). Well one to many clicks so it got too much heat in it with a new bottle.

At least now I have a checklist that I would go through every time. Nitrous isn't bad as long as everything is right on it. (Jets/Tuneup, Timing retarded, good fuel, bottle pressure, good solenoids).

Lesson learned

Nitrous is as safe as any other power adder. The thing is you have to make to keep in mind that run it safely you have to add more than just a base system. Window switches or progressives are one of your biggest safety features. Making sure you have the correct spark plugs would be a necessary change.

As with any power adder you have to make sure you dial in your tune for nitrous. Overly rich can kill a motor as fast as an overly lean condition.

if you have any questions feel free to reach out to us. We can answer anything for you. We have done plenty of 5th gen camaro plates, nozzles, direct ports and whipple/maggy direct ports. We even have a maggy plates.

DandD, Its mid 11s before the cam, not it should be well low 11s

and I do have nitrous and my set up is awesome...I have 2 tunes basically, the everyday aggressive tune for my boltons/cam...then I have a switch, the switch changes the inlet air temp from ambient to about 180-200 degree to trick the computer into pulling timing (I have to check with my tuner about how much timing he pulled when the switch is on) but anyway, that activates the nitrous system, I then have an MSD device that controls the window RPM and progressively shoots the shot. I shoot out of the hole so I have it set to progressive for about 1.5 seconds to prevent out of the hole tire spin (it pulses sorta) and then the full amount is shot...also it only shoots when I am at WOT and between 3000-6400 RPMs. That way if I go to my limiter, its not shooting anymore...I Love this whole setup. Lidio and Alternative Auto did an awesome job setting it up. I am never scared to shoot either because the set up in my opinion is safe and badass. I also have a purge and bottle warmer for max awesomeness hehe. This is a good set up because when your not shooting and racing or just cruising etc, your not losing out on max NA horsepower and efficiency, nothing is compromised. If you only have "one tune" then you compromise either your NA or NOS. I have aeroforce gauges to monitor these tunes...I look at engine advance, short trim, inlet air (which i make sure changes when I activate it), etc etc.

also, no problems at all with this setup...and I must have atleast 100 passes (either at the track or on the street.

Nitrous pressure

Would a system that offers the option to disable the nitrous if the pressure is too high or too low be something that would have been useful in this situation? Our new nitrous controller has an AFR safety shut off and a fuel pressure safety shut off option but I didn't think to include a nitrous pressure disable feature.

If people think this would be useful we could look into adding it in a future software update.

BTW - our controller also offers closed loop control of the bottle heater based on nitrous pressure so that might have helped this situation too.

I've run nitrous twice in the last 14 years, and the last combo ran pretty good... H/C/I/TH400/9" 4th gen + 150 shot/ 3300rw = 10.008@134 1.38.

If I run about 12.3 on motor I wonder what I'd run with a 100 shot.

I ran a 12.1 on motor before the cam and 11.6 on nitrous (100 shot) before the cam (with a terrible 60 and no traction)...
