Anyone running propane injection?

I know Jay Carter is working on a setup, and claims he has had great results with it. Perhaps Jay will chime in. ( I hope I didn't let the cat out of the bag Jay ;) )

Here's what I can tell you. Unfortunately I dont have a price yet since we are still experimenting with different components.

For several reasons, we ended up having to have solonoids custom made. I couldn't find anything that was available through any of the nitrous people or industrial supply places that would do what I wanted to do so for performance and safety, we had our own made.

This kit is much easier to tune than alcohol. Some of you probably noticed I said in the alcohol forum a while back that I was not going to be selling alcohol kits anymore. This is why.

Results are sort of on par with alcohol. It's a bit hard to explain but I'll just say that my most diligent tester, who I will get to chime in on this thread, is running 23-24 PSI on 93 octane with a 20 degree chip.

From a safety standpoint, we have taken about every precaution that can be taken. While Im sure there will be people who this idea scares the hell out of them, you have an 16 gallon bomb sitting underneath your trunk. I'd be more worried about that than this from a "getting in an accident standpoint." Without having pictures to show how we are doing things, that probably doesnt mean a whole lot.

None of the testers have had to refill their tanks yet. Testing has been going on for about 5 months now. Before someone rushes out and tries it, we aren't using your dad's BBQ tank.

Kits will be available from OGS Distrubuting and probably Downtown Motorsports (Kenny Brown) and possibly Charged Air Systems. Anyone interested in a kit, email Dan at OGS and bug him to speed things up, I'm waiting on him :D

Final words... I know there are going to be people who say to themselves "I can build this and save myself some money" and that's all cool.. but, Dan and I have spent a lot of time trying to cover every "What if XXXXXXXX goes wrong" scenarios out there and that is what's led to a lot of custom made pieces for this kit. We probably don't have everything covered but we have everything that we could come up with covered. Short of you getting hit by a semi or dump truck at just the right spot, I think this is a perfectly safe enhancement. If you do get hit by a semi or a dump truck in just the right spot, rest assured you will have much bigger problems than that propane system. Point I'm trying to make is don't rush out and hastily try to copy this kit without doing some serious research. You could end up regretting it later.
 
I have had one of Jay's kits (his second) on my car for about 4 months and am still getting more out of it. I have a mid 12 second car in street trim and I bettered my best pump gas time the second trip down the track with propane and a 2/10th's slower 60' time. I have seen a 2 MPH increase as well. This was versus a Variable Timing chip and 20 lbs of boost. I am running one of Jay's regular street (93 octane) chips with the propane injection. I can run 17 lbs of boost with this chip and no propane.

I have taken pretty small steps to see how far you can go, but have run 22-24 lbs of boost with no knock. And as Jay mentioned, no refills yet. Not much of the kit is the same as when it was installed, and I am about to get basically a whole new setup based on what we've learned so far. The over the counter parts were not doing the job. I know I have not reached the limits of the kit yet and am still playing with it.

The biggest seat of the pants difference is how fast the car spools from a roll now. It wasn't something I was looking for, but it was obvious enough to notice. I am certain the track results will improve further with the right hardware.
 
Good to see there is some research going into this. From what I have read here and there propane can be the ticket to unlocking horsepower that alky cant produce, or do consitantly. From what I understand alky while loose octane rather fast sitting in a injection system where propane never changes.

On another note...
Listen to Jay on this one. Not something you want to try and build from a Coleman camp stove and some n2o solenoids. With alky if it leaks its no biggie, n2o leaks so you get a little happy while driving, propane leak + spark = convertible gn. :eek:

If you need another test car...hint hint hint...something in the low 11 high 10 range let me know...hint hint hint... :D
 
My understanding is with alcohol, you are adding a knock suppressant by raising the octane of your fuel. With propane, you are adding a knock suppressant AND fuel. That's the approach I have taken in tuning Jay's kit.
 
What are we looking at as far as price for one of these kits?

Sounds very interesting, except for that convertible part. :D
 
wow sounds cool!

hey if you need a bone stock test car, ughh well HI! lol j/k

sounds like u guys are making some progress, any drawbacks of propane? from what i've read alchy can start to eat rubber and stuff, i assume propane doesn't do that..
 
So far the only drawbacks have been that Kenny can't seem to get the boost up high enough to make it knock with a street chip. Also, FWIW, propane doesn't suffer from the "tip in stutter" that alcohol can. At one point, Kenny was turning the kit on at 5 PSI.

As far as cost, I really don't know because I'm still testing a variety of solonoids plus I won't be selling the kit directly. Dan and the other guys will be so pricing will be up to him. I do know that there are going to be optional accessories you can purchase to upgrade the kit from the base kit. You will be able to add them after the fact relatively easy.

that's a drawback?????!?!?!?!?! **** sign me up! lol
 
This idea is borrowed from the turbo diesel world. They needed to increase power and save money yet not buy new fuel system components. So propane injection was born and looks to be way more promising in the long run than alky.

Check out the 3000gt/stealth sites, there are alot of guys running this already and having great results. There is a supra out there running 26 psi on pump gas doing high 10's. There will definitely be some buicks doing that with this.

It's great to see guys like Jay keep evolving the systems to not only keep up but surpass expectations. This stuff will last for months and its cheap. Could not get any better.
(Probably what they said about alky)

One benefit to propane is that smaller injectors are going to go way deeper into the e.t. Thats one reason why this was engineered in the first place. Looks like my 36 lbs are staying for awhile now.

Keep up the good work guys,
I need to spank some of these imports starting to catch up to us.
 
Actually the guy doing propane in the 3000GT world is Matt at Dynamic Racing. Matt and I have been working together on this whole deal for over 6 months. The Supra you refer to is John Gonzalez's car. He is a former Buick guy and owns the server the buick.fiendish.net chat server is run from.

My kit is going to be somewhat different than Matt's. Matt has a reasonably solid design for his kit but it's essentially a bare boned kit and I'm interested in making my system more robust than what he has as well as using more specialized components. When I have everything nailed down, I will be sharing my findings/sources with Matt so that he can revamp his kit also should he see fit.

There may be some other 3000 GT/Stealth guys doing propane but Matt was the guy who was leading the way with those guys. I don't really keep up with them so I can't say either way.
 
also is the kit going to be different for an fbody than a GN? i'd assume so but just asking :)
 
Hay Jay,
Do you need a stage 2 street car for testing. I have 485 miles on my stage 2 with M&As. Very similar to the setup that I sold you and Nelson back in the mid 90s. Ruggles didn't build this one.

It is getting time to apply some boost to it.

Let me know.

got any PICTURES or some more info on what ya'll have in store for us???

i put propane on my 86 t-type 2.5 years ago and had good luck with it-- the only problem was BOTTLE SIZE and not being able to get enough boost!!! at the time i was scared to take the car above 22 psi
the car would literally get richer on the top end--
i was nieve and took the system off the car cause i didnt have a big enough turbo for the car-

what is soo cool about propane, its 117 OCTANE,

ive got a few Questions for you JayC

1. are you going to be putting in a mixer ( converts liquid propane into vapor) and shooting vapor into the uppipe?
or just using HC5 propane as a liquid and letting it expand as it reaches the intake tract??
2. what size bottle ? 5-10 lb bottle?
3. when can i get some specs on it??

im hooked!!! ive been wanting to do something just like this on my racecar for extra fuel-

PS- when i did this years ago i used a 33lb forklift bottle- and at the bottle i was able to use a HYSTER FORKLIFT propane shutoff valve-
i have that valve sitting in front of me right now
ADVANDED FUEL COMPONENTS is the maker of it and it holds 312 PSI of line pressure, and is 12 volt activated
* if you would like, i can get you the part # off of it and see if you like it-
 
JC what i like to know is?

Is this kit gonna be on average as the same price for the SMC ALKy kit or more and when do you expect to start distributing this propane kit

Not yet

The system uses vapor, not liquid. I have tested liquid as well and dont really like it.

3. when can i get some specs on it??

At this time you can't since I haven't finalized all of the parts we're going to use yet. I have one more shipment of solenoids coming to test then I will make the decision as to which one to use.

I thought about doing this but basically here is the situation I don't want to be in. I don't want to be selling a $750.00 propane system. I could keep adding stuff and keep adding stuff and drive the price through the roof but no one is going to buy it. So instead, we are trying to devise a system that has great room to grow so if you want to start with the base kit and expand later, you can. After we finish testing the new solenoids, I am going to get with Dan and hammer out a price of the kit and whatever accessories we decide to offer. At present, I believe we have 3 additional components that can be added to the system at a later date or you can buy them all at once and have a super-duper system. The add on pieces mainly help in tuneability.

Is this kit gonna be on average as the same price for the SMC ALKy kit or more and when do you expect to start distributing this propane kit

The base kit will hopefully be right around that price. I'd like to see the kits available within the next 4-6 weeks but with having to have solenoids custom made, that may be asking a lot.
 
Jay, are u going to design one for the fbody as well or just the GN, or are they going to be interchangable?
