Intresting propane article

[TEST MY 6]

not really tech for us but good http://caranddriver.com/article.asp?section_id=26&article_id=2279

They aren't even CLOSE to using up the potential of that fuel. With boost it would SCREEEEEEEEEEEEEEEEEAM!

Yeah, I am propane crazy.

I think we need to harass Bi-Phase to make up a kit for our LC2 engines
If they are getting 10-15HP from converting a regular gas engine to propane, imagine what it would be with a boosted engine going from 91 octane to 104 or 110 octane fuel that also cools the intake charge. Crank up the boost and you would probably see somewhere around 50-75HP on a bone stock engine.

Count me in

There is NO clinical proof that propane offers any significant drop in intake charge temperatures. NONE.

No clintical proof? Hehe, you have been watching too many comercials on tv..

True the propane injection we use works well since it causes a more complete burn once mixed with the intake charge. Vapor injection doesn't really cool the intake..

But what about when using it in liquid form? It's like -50 degrees Far. comming out of the bottle....

I don't really know, I'm just wondering, and if it really makes that much difference.

Even alchy causes a 20 degree (or thereabouts) drop in intake temps, but using it results in a couple hundred degree drop in egt's.It's all about what happens at the top of the compression stroke.
