I've been talking to a guy about nitrous and his truck. Turns out that he is using a big shot of nitrous.
Below is his latest message

.Now I don't know if anyone here is running propane on their lightning, but what are your thoughts

It makes sense since a lit of diesels are running propane injection. But instead of using it as cooling, it is used as a catalyst to burn in the a/f ratio.


THOUGHTS?


edit:
He has the stock (yes stock) gasoline engine in his truck, NOT DIESEL and is running pretty good 1/4 mile times. I'm impressed.

 

NE1? ttt

 

A diesel uses propane as you can't spray diesel fuel through an injector like a petrol 'wet kit'. To get additional fuel on a diesel using a standard dry kit, you need to up the pressure to the injectors and/or fit bigger injectors. This can get expensive.

There is no reason to use propane on a vehicle tha can utilize the factory petrol with much more ease and consistancy. Propane needs to have a certain pressure like the nitorus side to keep jetting consistant. Petrol is a stabilized pressure already through the factory lines. Nitrous is hard enough to tune with the nitrous side fluctuating, you don't need the fuel side pressure changing also.

Propane can only be injected to a certain power level on a diesel. The reason being is that the propane is being highly compressed and can self ignite under these pressures before the standard diesel is injected. This is also another reason that diesel fuel can't be injected via a wet kit prematurely.

Propane requires another bottle to be mounted, filled, lines to be run, etc.

 

race', thanks for the explaination. I've also been wondering why noone was running propane on Lightnings, now I know.

 

There will be some tuners that may try to sell you on propane being superior. Just walk away from these people. Why make things more complicated than they need to be. I haven't seen it in the L community but on other applications. The fact is you can make just as much power on petrol if tuned properly. YES propane has a higher octane rating, but 'most' applications don't need 98 octane for the street. For track use, you can use toulene to boost octane or run high octane fuel.

 

Okay.. i understand...

Thanks Nitrous Guru!

 

Ever thought about the fact that the octane of propane is MUCH higher than gasoline? On a wet kit, PROPANE is MUCH safer than GASOLINE, but the problem people have is the PIA of the 2nd bottle and filling it. Ive watched this type of setup in person, and it is proven with BIG nitrous shots to work. Say what you want, but I've seen it in person.

 

he's spraying a 150 shot.
is that big enough?

 

Sure. Makes a lot of sense to me. Why do people run race gas with lots of timing? Hmmm... Why is it recommended to splash race gas in when spraying? Hmmm.... Only makes sense to run fuel which is 100+ octane with Nitrous.... Propane makes that happen.

 

Turbo Buicks seem to luv the stuff http://turbobuick.com/forums/forumdi...?s=&forumid=14

PS....Well at least they used to be. Last year it was the rage, I guess times change.

 

Mecca,
I mentioned the higher octane rating. Why do you say propane is safer than petrol as this makes no sense? They are just different fuel supplies. I said the things I did as we are nitrous kit manufacturers and have first hand experience also. Your comments on nitrous and race fuel make no sense either. One engine may be able to spray 100 shot on pump gas and another only 25 hp before detonation occurs. It depends on the set-up. Nitrous and race fuel do not go hand and hand. Many applications are fine on pump fuel. Please don't add to the ignorance of nitrous oxide and how it works on a motor. There are enough myths out there.


Dale,
Your are right about the rage. Propane is just a higher octane fuel supply, but it doesn't make more power than petrol can at the same octane rating.

To recap and add a bit moe information.
1) Propane has an octane of 98 if I recall correctly.
2) Propane is a dry fuel and can be beneficial for some applications(very few that we know of).

For the majority of nitrous applications (I would say 90+%), especially street, propane would be more trouble than good because of the factors I mentioned earlier.
