After reading a thread about propane injection (i forget where) it has sparked an intreast in me

i was wondering, if you ran a wet nitrous system, but instead of using gas you used propane, would you get net more power than from just running the wet system with your gasoline?

i know its extra equipment and weight to haul around, which could possibly negate any performance gains, but i still want to know

i know that combo does some outrageous stuff for diesel engines. But for the rotary your guess is as good as mine.

It might burn too hot... I'm not a chemist though.

yeah, from what i hear damn desile engines can take just bout anything

50lb's boost w/o a wastegate, mygod thats nuts

i guess ill browse the webmore trying to find a reason why NOT to do this

ok, turns out this sort of kits exsists for vipers, found a few sites that sell em, ill just post the one im at now

as for tempetures i havent read anything yeat, this might be a fun project..

mmm propane injection...

i work with propane and let me tell you use one or the other!!! propane is 125 octane !!! you can replace a gas/nitrous fueled engine for a propane engine but dont do combos!! its useless and creates way too much heat that will eat any engine.

Ive seen a turbo viper with nitrous with propane injection. I wouldnt say its 'useless'

Jimmy325i

Where do you get this 125 octane number from?


"Engine Life: Propane's 104 pump octane rating and low carbon and oil contamination characteristics can result in documented engine life of 529 to three times that of gasoline. This is one of the prime reasons for propane's popularity in delivery fleets, taxis, buses and industrial engines."

cited from this site

But when you start adding additional oxygen, just like with any fuel you raise the speed at which it burns, and also the heat it generates in the process.

Nitrousoxide is used for the simple fact that the nitrogen consumes the space between the oxygen molecules and prevents an extremely fast burn of the gasoline.

so running a shot of nitrous and propane would negate the effects gained from the slower buring propane, except for the cooling effect that im guessing that would occure?


when it comes to your typical wet n20 system, you run a pre-determined shot of n20 and your highoctane gas, but instead of using 93 octane gas (only crap i can get up here unless i drive south 40 min, then i get onehundred something) would it be better to shoot propane?

Jimmy325i

N2O makes power in a couple ways...

It adds additional oxygen (but not too much, preventing the higher combustion temps) to facilitate burning more fuel. (which is all forced induction does)

It also cools the intake charge allowing for even more additional fuel and oxyegen to be added without the mixture reaching its flash point from compression before the spark ignites the charge. (detonation or pre-ignition)

The nitrogen molecules add buffers for the combustion process which keeps the speed of the flame traveling down from where it would be with straight oxygen injection.

Welsh Technologies, http://www.welshtec.com/, makes dual fuel systems and currently has their setup running on many cars. check out their site for descriptions of stuffs.

the systems on that page seem to all be alternative fuels sytems, great info but not what im looking for

Diesel engines are great. They run about twice the compresson of a typical gasoline engine (like 24:1), last longer, get better gas milage, and diesel fuel is cheaper. The only problem, they are engines for torque.

There is gonna be a truck here in Lousiville around Valentine's Day that went to Bonneville and recorded a 225 mph speed...a truck!!! It is like 700 HP and 1300 ft-lbs of torque from about a 5.9 L engine, and it gets over 21 mpg! Bows me away.

Granted, think of what you can do with a 5.9 L Wankel

ive seen a few crazy Diesel engines on t.v.

one particular one stands to mind, about 2 weeks ago on speedvision they were showing a few of thoes supertrucks race on mazdas track (forgot the name, lacsua something like that) and they had a truck with a v8 putting down 1200hp and 3000tq, was freaking insane

ya, they're pretty slick...and they sound great
