Has anyone ever use propane with N20 instead of gas? The reason is ask is for 2 reasons. 1 No need to do extra fuel pump and lines. 2 I see some pretty high end exoctics with this setup.
Any thoughs would be appreciated. I have alread checked and there is a 15 pound propane tank DOT rated anout the size and shape of a N20 tank. as I recall a few years ago there as an writeup in one of the mags. using n20 and propane on a viper.

ps
Hank Hill at Strickland Propane didnt know sh** about N20 and propane! :)

BTR Performance (http://www.btrviper.com/) sells nitrous/propane kits for the Viper and the Corvette. You don't need a 15# propane bottle. Their kits include a 5# propane tank. The Corvette kit is LS-1 specific, and seems to be limited to about 150HP. And not cheap, at $1,299.

Propane parts include:
-5 pound refillable DOT-ANSI approved propane bottle
-Adapter to AN style fittings
-propane pressure gauge
-solenoids
-jetting
-braided high pressure feed lines and much more.

I've seen the kit installed and dyno tested on a Viper. The car was already making almost 500rwHP with minor boltons, and the propane kit pushed it to over 650rwHP.

Here's the BTR FAQ for the Viper kit:
BTR-NOS Nitrous Oxide/Propane Injection System

1) Why propane?

Cleanest burning, safest, cheapest, highest octane fuel additive available. No need to starve your injectors or add another fuel system.

2) How is the system activated?

By voltage from the Throttle Positioning Sensor. System is activated by 3 volts of throttle pressure.

3) Can I install at home?

Yes, and with normal shop tools.

4) Can the System/Wires be seen in the engine compartment?

No, this system is virtually invisible.

5) How/Where are the bottles mounted?

Bottles are mounted in the spare tire well with the supplied brackets.

6) How long do the bottles last?

About 12 ¼ mile runs for the Nitrous, about 60 runs for the propane.

7) Why inject before the butterflies instead of into the intake runners like other systems?

Safety feature. In the event of a solenoid stuck open Nitrous/Propane will flow out of the airbox when TB butterflies are closed unlike other systems which use Intake Runner Direct Port Injection where a stuck solenoid will result in nitrous flowing directly into the engine until the bottle is turned off or runs out.

8) Can I adjust the horsepower level and or run without propane?

Yes, several jets size combinations from 75 to 225 horsepower are included.

9) Do I need different spark plugs, and race gas?

No.

10) Can my engine reliably handle the added power of nitrous?

Absolutely. Your engine has forged aluminum pistons, and a forged steel crankshaft. These are preferred components of any nitrous engine builder. The Viper engine also incorporates the same crankshaft bolt patterns as the legendary "Hemi" and today's 6000+ Horsepower top fuel engines.

11) Is nitrous safe for 2000 and on Vipers?

Yes, nitrous is safe for 2000 and on Vipers with their new cast pistons.

Has anyone here actually ever used a propane setup? If you did what was it like?

Out of curiousity why is it so expensive?

Isn't it just basically a 2nd N20 kit except uses propane and needs to be tuned properly?

How i want to do mine is convert a wet kit to propane. I keep hearing good things about propane and N20. I have a machine shop, lathe and mill, so making own jets is no big thing. I was thinking about basically moving the gas line to a propane. Finding a 5-10 pound propane bottle seems to be the trick.

My dad has a 98.5 dodge cummins that we took to a dyno and there was another guy there also with a cummins and he was running n20 and propane.Made like 750 horse.....it was pretty crazy. made 600 with the n20 and 750 with the propane

Are you sure they were even using nitrous on the diesel? Propane injection (only propane) is routinely used to boost diesel HP.

It took about 10 seconds with a Google search.... DOT rated, $66:

to further explain it.


whats the diff between that $66 DOT approved liquid propane bottle and the $110+ DOT approved liquid nitrous bottle?



the answer is, who sells it.

Ya he was using it. Why couldnt they use N20. I've seen a bunch of NX kits for Diesels. I guess some shoot it before the intercooler.

No it isn't.

A nitrous bottle is made out of heavy wall aluminum, has an 1,800psi "working pressure" and has to be rated at 3,000psi burst pressure. The vapor pressure of nitrous at 100degF is 1,100psi.

A propane bottle is stamped sheet steel, and only needs to meet a working pressure of 250-265psi, and a burst pressure of 500psi. The vapor pressure of propane at 100degF is only 172psi.

Like comparing apples and aardvarks.

Yea. try filling that propane bottle with Nitrous and heat it to 1000psi(working pressure). BTW that was a Joke. DO NOT try it please. I dont want to hear about it.
