Nitrous Explosion

[Ivory]

Ok, I had to make you look. Trying to avoid a Nitrous Explosion on my Gen 1.

Gen 1 owner with 40k on strong stock motor, tubes/filters interested in installing a NX 150-300hp shot kit on car. Want to hear from other Gen 1 owners about installation.

How long to install?
Special tools to install?
Plug types/gap?

Optional items necessary above the base kit?
Undocumented tips/tricks
HP generated with jet used?
Additional safety features installed?

How many 1/4 mile runs on 10lb bottle?
Is a bottle warmer necessary?
Is a remote bottle opener required?
What to watch out for with A/F ratios?

Is this a do it yourself install and go without a dyno?

Any help would be appreciated.

With so many questions why not find a good mechanic that works on race cars to help you?
Nitrous has always scared me. I don't know if I'd be up for the challenge. Hope it works out for you

I have a Gen 1 (1993)with NX Express system. You could call Lee Dove, he was very helpful with my kit!


How long to install?

I took it slowly and wanted to do a A-1 job, so the Viper was on jackstands 2 weeks. Yes, it can be done in one day too... I wanted to find S/S nuts bolts, fittings, most of the time went into figuring out best way (aestitically and functionally)to do the "plumbing".


Special tools to install?
No. Good wrenches is a must, unless you want to damage anodized fitting.

Plug types/gap?
NGK ZFR6F-11 Stock #4291, Gap between 0.30-0.33
My understanding is that with 100HP shot you could use regular Champion plugs.

Optional items necessary above the base kit?
I chose billet aluminum bottleholder and dual tanks. I chose not to use the cheesy looking NX switches and bought better ones. Two NOS purge nozzles mounted in front.

Undocumented tips/tricks
No.

HP generated with jet used?
562HP/712TQ with pig-rich mixture. 52-33Jets (200-shot).
I cut my own jets for "in-between" sizes to further tuning, tomorrow is dynoday, so I'll let you know if I melted the pistons or gained power.

Additional safety features installed?
I chose not to use the fuel pressure sensors.

How many 1/4 mile runs on 10lb bottle?
None yet.

Is a bottle warmer necessary?
Absolutely, if you want to keep a constant optimum pressure in tank.

Is a remote bottle opener required?
Too much hazzle and possible issues with them functioning properly. I open valves when car goes out and close when it is parked.

What to watch out for with A/F ratios?
Lean mixture... It will melt catsize holes on top of the pistons.

Is this a do it yourself install and go without a dyno?
No. It is a do it yourself if you have some common sence and decent tools. A dyno is a must to verify your A/F ratio. Better safe than sorry.

Hope this helps!

Here are some numbers from a 1993 Gen 1 for you:

I dynoed the car today and it made: 597HP/ 768TQ

Not bad, eventhough I wish it would have made the lousy 3HP more....

Congrats! Wow sounds great. I can't wait to get a system. My car is mildly modded and now my fellow Gen 1 brothers are stepping up to Super Chargers, I need a little extra umph.

I'm planning on NX 300 shot system with 150-200 jets, bottle warmer, purge valve, and fuel safety valve.

Will order in the next few days and find an installer.

Glad to see that you are making good horsepower!

Your nitrous sure comes on early! It sure drops off fast too!
