I know, it sounds like about as logical a mod as a flux capacitor, but hear me out: The guy at http://www.welshtec.com may make a website that looks designed by a 12 year old, but he says his kits are EPA approved, and make good increases on mpg and low-end torque. Coincidentally, my rx7 gets very poor gas mileage and low-end torque, and I've just gotten me a girlfriend in Sarasota.

Hope it doesn't blow the **** up or anything, but since propane is about 110 octane I think I oughta be good. Anyone wanna help put it in, to see what happens?

 

are you kidding me? You're going to install all of that shit to save a few mpg. How much is it costing you to save a few MPG?

 

Propane is cheap but not widely available. You can't exactly pull up to an LP station and fill your car up.

I was reading up about how to do this as well, it seems like it might be a good idea. Especially if you can leave the EGI system functional in case you need to run on gasoline.

 

I have only seen one gas station that supplies Propane.
hmph

 

I wasnt thinking of using it IN CONJUNCTION with gasoline. i meant more of a flip-of-a-switch and it runs entirely on LPG...

Why mix them to improve emissions?

 

I've considered all the variations--toggling from gas to lp would be ok, but require a lot of modifications--and some place to put an extra, large tank. With the simultaneous system, you only use a 2.5 to 7 gallon tank, and the kit doesn't look like a multiple day job.

Also, 'cause the guy also says it will improve mpg by around 25% while increasing low-end torque--again, two things sorely lacking in the rx7.
