Nitrous

[Torquemonster]

Russ M's reply is a very good one.

On carby engines the old Jacobs Nitrous Mastermind or something similar provided a basic EMS for nitrous. It regulated the flow according to engine demands and rpm, adjusting timing & mixture according to the presence and flow rate of the nitrous.... this makes high nitrous shots much safer and engine life considerably longer... Guys who ran just the NOS kits usually ended in tears at some point.

but for EFI - I would assume that nitrous kits fitted to Vipers come with a way of controlling flows at low rpm and increasing NOS as rpm and load increases, I'd also assume that some kind of EMS enhancement would compensate for nitrous via a retard timing map and fuel enrichening mixture map for when Nitrous is on... with knock sensor providing back up protection via additional retard as required... am I correct? If not, I'd leave bolt on NOS for the brave, and spend more money for a profesionally built setup that can be controlled precisely.

Supra(Guily),

Hey, yep that was Joels Benz the **** thing would take all the nitrous we could through at it. When we ran into the limitation of the single line/bottle setup he installed a second NX kit and ran a 200 primary and a 225 second stage. The most amazing part of it was that the engine was out of a car that had 120k miles on it, and it started racing at that point.

Tabratton,

A good NX kit/BTR kit installed and jetted by the right person is all you would need. Both of these are capable of running exceptionally safe. I am not sure on the BTR kit, but an NX kit installed and tuned should not cost more than $2000.00 with all the bells and whistles.

Russ M thanks for everything that sounds like what I will be getting the 01' yellow with black stripe and 225 shot of Nx, what is btr. There is a shop hear in Nashville that has a viper mechanic and has done nitrous installs for other members of the forum. Thanks again

tabratton,
Didn't you know those yellow Vipers are faster from the factory

. You won't even need the nitrous

Hello,

Please check our website for a complete line of safe, reliable and extremely powerful nitrous kits for any year Viper. The new hyperutectic piston Vipers are doing very, very well with our kits and 200+ rwhp is commonplace. Check recent posts of dyno results from several cutomers on these forums and also see dyno and dragstrip results of our proven effective systems by clicking on the link below.

Thanks,

Tom

As long as the fuel mixture is right and timing is good there is no reason why you cant run a small amount of nitrous through a cast piston motor. After all a 225 shot is only 22.5 hp per cylinder, and should be considered the small shot.

I have seen a totally stock Benz motor take a 425 shot for 2 years of pure drag racing. And unless I am mistaken this motor had cast pistons in it(6.9 v8). And the motor still runs perfect to this day, with over 150k miles on it.

The only thing that will determine how your motor deals with the additional power is tuning. It is by far the most important factor in longevity of an engine.

Hey Russ was that Joel's Benz? If it is I didn't know he was running that much NOS!
