I was wondering if anybody has heard of using propane instead of Meth for fuel suppliment/octane boost? Propane is 104 octane, has about 90% of gasoline's BTU's and runs about $3.25 in my neighborhood.

Since Propane is under pressure, I wouldn't need a pump so I think it could be a lowcost setup. I was thinking of using a BBQ propane tank to supply to vaporized propane. Propane is at about 125psi at 70 degrees ambiant temp so I coule use a propane regulator to hold it to about 75psi to keep to deliverly at a stable psi regardless of outside temps. I could use a N2O solenoid w/hobbs switch to activate at a set boost level (like a Stage 1 Meth kit) and Meth injectors. Finding out the right size "jet" would take some experimenting. A Stage 2 kit could be put together using a N2O progressive hardware.

Sound do-able? I'm probably missing something but it's just the first draft of an idea.

Thanks, Rick

ive thought about this too. they use it in diesels all the time but they say it raises egt's quite a bit. +1 for this idea.

Does propane have the same cooling effect on the air charge?

I think it would work out great. You could have 104 octane and a bbq grill for tailgating.

One of the ways Meth/H2O lowers the IAT is that it asorbs heat while converting from liquid to a gas. The Propane would be injected in a gaseous state for I think it will provide little reduction in IAT's.

If you used a N2O bottle to hold the Propane, it would be fed in a liquid state. Sounds like a better idea. Traditonally, propane autos used a vaporizer warmed by the radiator water to make the propane become a gas. It you added the propane before the intercooler, it should guarentee vaporization. would the propane have any negative side effects on the MAF?

When I had propane on my diesel, I popped two head gaskets. It is a good way to burn all your fuel in a diesel but,it is a dirty gas. I liked propane but, wouldn't recommend using it to anyone. I have never had it on a gas motor it might do great. The Bullydog injector comes with a built in solenoid and all hoses you would need to hook up to radiator lines.

ive seen wet nitrous setups that use propane instead of gas. let me look for some pictures

search BTR propane on google
