Sounds really good. I didn't know it had that many tuning points. It increases the flow in proportion to boost? What causes the solinoid pulse width to stay open longer as rpms or boost go up?

You're right about the rpm thing. It would only be coming on at 90% + throttle position, but do you think a window switch would do anything positive?

I'm only running 6-7 lbs now, I just want to be able to run 11 lbs without knock retard, efficiently and safely. They have motors that run off propane exclusivly, as I'm sure you know. But they must have totally mappable fuel systems, prolly via laptop. Too expensive? How much? How would my truck run if it ran exclusivly on propane? Wouldn't it be much cheaper to operate just a pain in the azz to refil? The stuff is 110 octane right? I could shave my heads if I could run off propane all the time. Call me crazy. I dunno if that would work.

Hey Jay, I'm Chris from Clearwater/Tampa, remember me? I had the tta that you worked on. That thing ran 12s with no alky or fuel mods, so I'd say you tought me a few things Andre still has 2 ttas and lives in Gainesville. I work as an independent rep here in orlando. Life is good. Congrats on the baby

The delivery is constant when the system engages. There is no proportional delivery. Again, that would take specialized electronics and we're trying to keep the cost reasonable, plus, again, in our testing, its not necessary. It's very hard to deliver too much propane to an engine. You have to engage the system very early boost wise and dump a LOT in to get the engine to even notice it.

Kenny has brought his kit on as early as 10 PSI with a jet larger than we are shipping with the kit and had no adverse effects.

I did toy with the idea of using a boost referenced regulator but I changed my mind after all the testing. I just dont think it's necessary plus the quality of the regulator we are using is just too good to replace with something inferior.

Good to see your still around, Chris. The good old Florida days.

Is there a low propane feature on the command center? I could not tell from the pic. That would be great to have!

Thanks

All I want to be able to do is let the propane take over for the inadequate fuel system when boost rises over 5 psi and deliver enough fuel to allow an 11 or 13 psi pulley. The stock fuel system runs out of fuel pressure at high rpm/high gear/WOT, so it is only able to provide enough fuel for up to about 4500 rpms t WOT at 6-7 psi of boost. I want a setup that would accomidate nearly twice the boost I'm pushing now by itself. I also want longevity and effieiency. Can you reccomend a jet size for my setup? Can I expect that much out of the propane kit or do I need other mods like bigger injectors, fuel pump etc.? Thanks for the advise.

Could you plug the tank right into your grill at a tailgate

BBQ some chicken N tires!!!


PS: going digital with a pulse width controlled injection would get real expensive real kwik and it isn't absolutely necessary unless u want extreme boost!! Im doing this kinda deal (with alky) and it aint cheap - the sensor alone is $200!!!!

From what I understand from what I have read... you will have to lean your current fuel map out for the current boost once you add propane... or put another way... you can increase your boost by adding propane without having to increase your fuel!

Jay,
Im trying to figure out how your kit works (different then others).
does the propane come on at a preset boost like a hobbs switch? Are you able to adjust the pressure of the propane with a dial or do you have to swap out jets?
I have a 99 turbo transam (ls1) were i dont use a lot of boost (10psi now) i would like to be able to set it at less then 10psi to come on. that way when it hits say 14psi the propane would already be flowing to reduce knock.

The kit is adjustable 3 ways. First you can adjust pressure at the tank with the regulator. Secondly you can adjust the amount injected by changing the jets up front. Thirdly you can trim the amount injected by varying the solenoid pulse width from inside the car. You can also adjust the point (Boost level) the propane engages from inside the car, from 0 to 18 PSI.

Hope that helps.

Thanks that helps some, but i dont know what pulse width is, can you explain it to me.
thanks.

HEY JAY
WILL YOUR PRODUCT WORK ON A HOT AIR? I CAN ONLY HOPE THAT IT WILL . I KNOW A LOT OF HOT AIR GUYS ARE FOLLOWING THIS POST. AT THE BACK OF THE HOT AIR MANIFOLD, I WOULD GUESS, IS WHERE YOU COULD PLUMB THE PROPANE (THE ADAPTER FROM THE TURBO TO THE MANIFOLD). I DON'T THINK I WOULD PLUMB INTO THE TURBO LIKE SOME HOT AIR GUYS ARE DOING WITH ALKY. I WOULD THINK THAT BUY USING PROPANE TO COOL A HOT AIR CHARGE (300+ DEGREES), YOU COULD LOWER THE CHARGE. I HAVE SEEN WHAT PROPANE DOES ON A DIESEL, AND CAN ONLY IMAGINE WHAT IT WILL DO ON AHOT AIR. THE INTERCOOLER CROWD WILL SEE SOME GREAT GAINS AND I CAN ONLY DREAM OF WHAT IT WILL DO ON A HOT AIR. I HAVE A FRIEND WITH A TURBO PINTO , HE RUNS ALKY BECAUSE HE DOESNT HAVE THE ROOM TO PLUMB A INTERCOOLER (PLUS, THE CAR IS ON A DIET). HE WENT FROM 7.30 TO 6.80 IN THE EIGHTH, SPRAYING AKLY.... BTW THAT CAR ALSO RUNS ON ALKY I TOLD HIM, HE IS STRAPPED IN A FLAMING BOMB

KEEP UP THE GOOD WORK

my first look at the system and the components look very sturdy, however, my only recommendation is to revise the styling of that control center to 21st century spec.

It doesn't have to be digtal display anything, but more compact, or at least a matte-black color, with some less blatent font style on it.

It might be great for the typically gaudy and tacky applique etiquete of the majority of the young import crowd, but big, especially bright colored control boxes in a un-flashy interior car (like the GN), just really look out of place, and are hard hide to do a stealthy install.

If I had the money right now, I'd buy the kit as is and just make myself a new matte black abs enclosure, likely out of a BUD box from Allied, Mouser or a similar electronics distributor and try and remote the "brains" of the electronics to under the dash and just run some small gauge leads to a beeper sized control box from Radio Shack to house the control knobs and indicator lights.. or go so far as to install the indicator lights into the vacant Power Injection bulb location in the stock dash.

Irregaurdless, I'm just quibbling on asthetics, besides that I'm glad Jay of all people is backing this system... since I do plan on buying it...

 

[JayC]

Yea, Ive said before that revising the electronics is going to raise the price probably another $150-$200.00. If people want to preorder a $790.00 propane kit and put their money where their mouth is, I will start on the new electronics now.

Otherwise we have to use what keeps the price reasonable. I would also have rathered use a different controller configuration but it's not cost effective to do it.

anyone?

Essentially the duty cycle of the solenoid is what you are controlling. You can vary the on/off time of the solenoid inside the car.
