Subscribed, I have always been fascinated by Nitrous but know nothing of how you set it up on a Viper.

I know approximately retarding timing by 2 degrees for every 50 HP is important for engine longevity , but not sure what most are doing for a Street/ Strip application……

up to shots of 200 you do not need to change the ignition time according to Nitrous-outlet

Must haves
1)Run a progressive controller like FJO. Many safeguards besides RPM window (you set the range) it sees throttle position and you can ramp your solenoid to pulsate low rpm then all in at a set rpm. For example I have 200 shot jets and I ramp it in at 2500 (pulsates 50% = 100 shot) then all in at 4500 (100% = 200 shot). Feels like a turbo coming on. easier on everything because it’s not a 200 shot / jolt all at once.
2)pressure gage – Always know your pressure before hitting the NOS / Optimal pressure nets best results
3)Bottle warmer or NANO it helps with #2
4)Correct plugs /colder than stock

Remember you got 10 cyl so 200 shot isn’t as big of shot as you might think. Your 488 Cubic inch will love it. I was always told NOS’s general safe rule of thumb is 20hp per cyl. 4cyl=80 / 8cyl=160 then 10cyl=200. If you’re going bigger than 200 then I suggest a tune / timing adjustment but at 200 you’re fine.
I’ve been spraying my car for over 10 years at no less than 50 bottles. My most recent compression test netted me a 7% range from lowest to highest.

Ha ok Thanks for your answer, and what do you think about a 18 jet for fuel and 41 jet for N2o ? It’s for a 150 shot, I have a 55psi pressure.

I need your help. I installed the nitrous outlet dual-plate kit on my ’97 dodge viper gts. I looked for information on the net and I have a lot of different information about the jet.

I would like to keep the maximum reliability of the engine and I chose the 150 shot.

What do you advise me?

the data nitrous outlet: 18 fuel and 41 n2o

on forum: 25 fuel and 46 n2o

on the program: 21 fuel and 41 n2o

​

It’s only to do 1-2 runs a year and I’d really like to keep my engine intact.

​

thank you very much for your answers
