direct port nitrous/propane
lots of the viper guys are using a propane system.
I'm interested if anyone has experience with a direct port propane system.
the propane burns really clean, is high octane, ez to get, cheap, and mixes well with nitrous.
I think a direct port propane system on my ZR1 would be really cool.
any thoughts???
tia for any info. I will check the viper forums and contact these guys. the system probably will need to be recalibrated quite a bit for a 350 instead of that truck motor 488. but I bet it will work cool. thinking of mounting the bottles down under the spare tire carrier, and using NX components for opening the bottles, and maybe fred to pulse the system to bring it on gradually to help with traction.
cya.

Re: direct port nitrous/propane (Rkreigh)
I know a guy that has the system on a stang. Its the same viper kit that he just adapted to work on his car. Its does great. Just a bit costly thats all. I suppose you just need to decide what you are trying to achieve. With all the different styles of nitrous kits out now, its more of a personal preference than anything. They will all work just fine.

Re: direct port nitrous/propane (LPDesRoche)
Ron, the Viper guys have the propane system worked out very well. The problem for me is that it adds another component that must be serviced regularly and it doubles all the plumbing. . A tank of nitrous, a tank of propane and a tank of gas is getting to be too much for my tastes. You would really have to stay on top of the propane refills to ensure that it did not go empty before the nitrous.

Re: direct port nitrous/propane (Rkreigh)
propane?
i have never heard if this in use with cars(only with grills)
how do you inject it?
how does it mix?
do you use it in shot like nos or do you run it in ur tank llike high octane?

Re: direct port nitrous/propane (RatRacer)
yes, it costs more, is more complicated, ect. but there are some big advantages. you can vary the bottle pressures independently to vary the mix (could also be VERY bad!!!) propane is dirt cheap. the pressure of the propane ensures you have plenty of fuel without adding another dedicated fuel system, and the propane is really high octane and expands just like the nitrous to add to the cooling. the other advantage is mixing. the two gasses mix easier than nitrous and fuel which can separate and cause some hot spots.
my goals are getting a cool nitrous system without the expense of race gas that I can run on the street. the other thing is taking advantage of some "viper tech" to kick some asp.
who makes the nitrous/propane kit for the viper guys??? I've looked through some viper mags but haven't found it yet.

http://btrviper.com/ does the Viper LPG nitrous systems. It would be a good way to get big HP for the track. The kind of power that would overpower the tires on the street.

Re: direct port nitrous/propane (OrangeC4)
I sent then an inquiry. stuff looks a bit pricey, and I want to see if the LS1 kit could work on a 95 ZR1. considering this vs a NX gemini.
I can get one of those for about HALF the propane setup. I'll keep you posted on results of my inquiry. :yesnod:

Re: direct port nitrous/propane (Rkreigh)
still no response to me email. I guess I will have to call them. I'm considering a direct port nitrous system with the fogger nozzles. I would like to get any thoughts you guys have. I have been following the "dry vs wet" debates with great interest. bottom line for me is that because the ZR1 has two injectors, dry kits probably work just great up to the point where the injectors "max out"
even though it may be overkill for my application, I think I may go either the "propane/NOS" direction or a direct port. I like the idea of mounting the bottles up under the spare tire mounting, but this also seems dangerous if I get "rear ended" I don't like the idea of having the bottles visible (cop magnet).
any tips guys??? great new forum. :jester

Re: direct port nitrous/propane (Rkreigh)
I would like the benefit of direct port foggers. The problem as I see it is all the plumbing that is involved. It gets in the way of sparkplug access. Not exactly what you want when you are checking plugs on a regular basis.

Re: direct port nitrous/propane (Rkreigh)
the only problem I see with it is putting that x-tra container inside the Vette. Propane is combustible, and if you ever have a gas leak inside the car, and just open a door... BOOM!!!
The fact it is high octane and you can run high HP shots while having pump gas in the tank is very attractive.
But the Big dogs in the Viper world running 9's on juice stay away from it.
As the propane perssure goes down the AF ratio changes....

Re: direct port nitrous/propane (RatRacer)
I was thinking of mounting the bottles under the spare tire carrier. but then again, a rear end collision could be BAD!!! the direct port and regular old dyno gas is looking better. how is that spray bar coming???
I'm REALLY interested in the new NOSzle. it would require some spacer plates, and I would not need all 16 of them (too expensive) so spacer would need to be machined to keep the fuel rail right (not too bad). not sure if this could be made to work with the ZR1, only kits are for a certain F*RD product.
ALL the plumbing would be under the plenum and very stealthy.
has anyone ever done a direct port setup into the injector housing under the plenum on the LT5???? now that Mr. Nitrous has passed, not sure who could help out with this. which tuners use nitrous the most on the LT5???
LPE I know helped out willie with an NX kit, but I don't want to drop 10K on a setup!!! thanks RatRacer!!! good advice.

Re: direct port nitrous/propane (Rkreigh)
We will begin development of the plates when Jeb gets his current customer engine build finished. If you want to install nitrous right now, I would suggest you purchase a NOS kit. There is a proprietary relay that comes with that kit that I think is crucial to using nitrous safely on the LT-5. You can't get it anywhere else because NOS and GM developed it. It acts as a window switch because it will not allow nitrous activation until the secondaries open(3000rpm). It also shuts the nitrous off automatically when the rev limiter is hit.
All of the kit will be usable with the spray bar plates so that way you will be ready when we are.

Re: direct port nitrous/propane (RatRacer)
I'm thinking of the new NOSzle stuff. 16 of these would be AWESOME. very expensive no doubt, as two complete kits would be needed, or machine some "spacers" and run just 8.
not sure if the ZR1 injectors will fit, but it sure looks exciting as the factory injectory targeting is maintained with a nice nitrous/fuel mix.
might just be the ticket!!!

Re: direct port nitrous/propane (HwyStar)
HwyStar, the kit is NOS #5172. This is a stand alone kit that does not require any add-ons. The backfire was caused by having a bottle pressure of over 1200psi. That was all my fault. I have since relocated the thermostat and everything is fine now.
E-mail me if you decide to buy this kit and I will fill you in on helpful hints that you will need to know for safe operation of nitrous on the ZR-1.
