I've searched and sent PM's out to those who have tried Propane as a fuel additive/extra shot with the NOS. No replies. So here I am.
So far what I've learned is the ratio is 10:1 for Nitrous to propane. Now to inject this into the motor directly or with the wet shot on the propane (or gas) Should I add a Y fitting (at the nitrous line going into my plate, so both Nitrous and propane are on at same time and injected at same location?) then use the according size jet for the propane?
Maybe use a seconday plate. Or inject the propane after the MAF and spray it in with the incoming air charge?
HELP, I'm tired of chasing faster cars.

 

put bigger nitrous jets in! you will get the added boost you are looking for

 

the red rooster booster, that was used in the 50's for farm tractors to give them some more power. it was propane. i dont know any gas stuff that people use propane, just diesels.

 

There was a guy on here (andy m..... not sure of last name) who was running a stock to the exhaust manifolds lt1 on a nitrous/propane mix in the high 10s. Hopefully he'll chime in.

 

sent him a pm same time as i made this post never have..I've gotten the info i need
one day i'll get it on the darn car..LOL

 

Propane/nitrous is a popular kit for the Viper. I've seen one installed and dyno tested. Same company that makes that kit also makes it for the Corvette.

injuneer...........................thank you

 

The links injuneer provided should give you all you need.

And, let me take this opportunity to thank Injuneer for providing the technical infomation he does on his website. Thank you (well written and easy to understand). I reference it often.

 

Thanks for the positive feedback.

 

you're always helpful

 

If your going to do it you have to use a wet nozzle or plate. On the gas side you hook up the propane instead of your fuel line. The fuel soleniods are not realy designed for the 160-180 PSi the propane will be at. I have some notes here on some jetting which you could start from. It seems like a few people started with the same size nitrous and fuel jet then leaned it out till the plugs looked good.

Are you limited by the fuel pump or do you have the misunderstading that you will make that much more power with the propane? The main advantage is propane is a little higher octane but you could do a 1 gal stand alone fuel sytem for the nitrous and run 110 in it.

 

reason for propane was more for higher octane, better distribution and no fuel soak.. Any info you can pass on is great

 

Technically, propane should make less power as it displaces incoming air. I never had any problems making power and every power level produced what I expected it should.

I do think there is some merit in improved fuel distribution, especially with the LT1's dry intake design.
