propane is a must for all turbo rotarys and N/A's. it cools down the intake temp by a grip and increases the octane level. and it is only $1.50 to refill.

ok i checked the other threads and i must ask. how does this stuff work on NA's? i mean there was some guy spouting off his own theories..but does anyone have experience using this with an NA car?

yes it works great with N/A's although they don't need the octiane it will let you get more HP without having to upgrade fuel system and propane come out at roughly -60degF that is 60 below. That will put the smake down on any cold air intake youv'e ever seen eh. we are going to organize a group buy soon. stay tuned. ;)

what kind off horsepower gains could there be on a Tii and N/A?

just dont get in a wreck with a bottle of propane. i have seen this used on big trucks but i thought it mainly added a LOT of torque.?.?

anyone have any links to non diesel info about propane injection?

there is your posts and read the hole thing of each. that way we don't have to keep answering the same questions.

I spoke with Chance (Call911) last night about this and it seems to be a quite legit way of making more power and keeping your apex seals in good condition. :) I am seriously considering going this route once my TII is running again, I'm just concerned about the amount of propane in a tank and how long it'll last.

Could just use a N2O bottle ;)

get a dry nitrous system but refill w/ propane :biggrin:

GIVE ME TWO TANKS! I NEED NOS!

hmmm...
 

I was talking to some engineers from Korea, and they mentioned something similar...Hydrogen Cell Injection System. Improves insane HP #'s and improves gas mileage. I just don't like the idea of a bottle of Hydrogen in my car, it can't be any safer than NOS.

But each cell is supposed to last like 1800 kilometers. (1100 miles?). Man the conversion from Kilometers to miles is as bad as the conversion (loss) from Canadian dollars to US dollars...YARG LoL

yeah but where do you refill your hydrogen at your nearest NASA biulding? J/K

you probly can get the hydrogen filled at paces the you buy aseteline(the gas you weld with) from. but the propane sounds alittle more safe. does anyone know the octine level of hydrogen??

I know I am bring this thread back from the dead, but did anyone ever put this propane kit on their RX? I just sent "WELSH TECHNOLOGIES" an e-mail about an RX-7 kit. Why did this thing blow over, is there something I don't know about this propane kit? It looks like a good idea.

By tonight? :rolleyes:

Alright guys I got some e-mails back for them, what do you guys think about this system? It don't look to expensive. Here are the e-mails I got:

Thank you for inquiry into Welsh Technologies products. Our Mizer-MFS Multi-Fuel System is a ideal application for your vehicle. The Mizer-MFS is a economic solution to increase the mileage and performance of your vehicle while reducing emissions to near-zero levels. The Mizer-MFS treats, controls, and injects a small measured equality of propane into the engine to maximize the combustion efficiency of the gasoline or diesel fuel. Instead of throwing the unburnt fuel away as harmful exhaust into the air or burning it up in the catalytic converter with out benefit of the energy; the Mizer-MFS allows maximize combustion of all the fuels in the engine with you getting benefit of the fuel's energy.

The Mizer-MFS is patented and patent pending alternate fuel system that has been engineered to be installed easy without any conversion or adjustment of the vehicle's engine; so there is not concerns with vehicle tampering or OEM warranties. The Mizer-MFS comes with a step by step installation manual and sells for $275.00 plus shipping. In addition to the Mizer-MFS an on-board storage for propane fuel is required. We offer our patented Propane 'Safety' Reservoirs starting at $330.00, that includes a remote mount 'Zero-Release Quick-Fill' and incorporates automatic overfill protection; or a conventional vehicle propane tank can be used; or even a barbecue cylinder if properly mounted and vented, although not recommended. For your vehicle I would recommend our 7 Gallon 'Safety' LPG Reservoir for $350.00. The only other items needed for installation would be copper refrigerant tubing, local available at plumbing or hardware stores, and miscellaneous items; all fittings are included.

The Mizer-MFS is classified by the US Department of Energy as a 'dual-fuel' alternate fuel system and if installed with a permanent reservoir or tank allows for a federal tax deduction and vehicles credits.

I would be happy to send you a brochure or address any of your questions or you can refer to our web site, www.welshtec.com, or call us with any questions. See what the Mizer-MFS can do for your vehicle!

Heres the second one:

A brochure will be in today's mail for you. One of the benefits of the Multi-Fuel system is that it increases the low end torque performance of the engine due to the enhanced combustion efficiency. It does not make your vehicle a rocket or increases RPM like a turbo, but gives a increase to the low end torque so it seems like your engine has more power at acceleration and if you have a automatic transmission you will notice it says in the gears more steadily even at going up hill. We find that most customers feel the increase in power and forget about it until they run out of the propane; where the vehicle returns to the pre-performance levels. So it doesn't occur again they keep filling up with propane. A common comment is that when the propane runs out it feels like a anchor went out. In fleets where the vehicle operators don't care about the emissions and saving benefits the performance increase keeps them refueling with the propane.

The system is nothing like a nitrous setup. The Mizer-MFS injects a constant flow of treated gaseous propane at all times of engine operation and injects more at load conditions, which is determined by a internal sensor that monitors the vacuum condition of the intake manifold in gasoline engines and a external throttle switch for diesel engine applications.

you don't weld with ACETYLENE, that's used for cutting torches along with oxygen. you weld with a mixture of %75 argon %25 CO2 for steel and for aluminum 100% argon.

No you DO weld with acetylene and oxygen. It's the old school crappy way of welding with just gas, not used much anymore.

I have been in a pickup truck that was converted over to running propane out of a backyard tank in the bed of the truck. The truck was a chevy 454 and it used to put the smack down on alot of people that my freind tried to race. He also got around 70 miles per gallon when we figured out how far you could go on a tank of propane vs the cost of a tank of gas. This also was in the summer heat of Pensacola FL so I don't think the warmer climates effect this. Its worth a shot in a rotary. I have a freind who has a na with no title so we might have to sacrafice it for the good of all rotory owners

This system does seem well suited to our cars. I guess my only concern is the holding tank and mounting as in car is both dangerous(no trunk) and cluttery (sp?).

If there were a way to mount an under vehicle tank I would be quite interested. I guess crash safety concerns would prohibit under car mounting (if even possible).

I have seen several sites where RX-7's have been converted but none as this easily applied (well from what I can gather from there non modern site).

Does anyone have any further input on this or has or is going to check it out?

is propane injection better than running a nice dual stage water injection?

Different application, this is discussing an alternative fuel/ Multi-Fuel System ,which is used to actually help power the vehicle. Water injection is basically cooling an intake charge.

I know that propane is used to make fuel more beneificial, but I know just slapping a water injection kit on a car at the same psi will give you at the least 15hp, not to mention the extra couple psi you can boost your stock turbo. What I was asking is which one will give you more hp for the money, water injection kits are $325 for a nice one, $235 for one that works good. or you can make your own for even cheaper.
