fuel

[zpwn06]

A lot of products are sold for cooling fuel lines, insulation of fuel lines, ect. Why are cooler fuel temperatures desirable? I was always under the impression you want cold air warm gas for optimum mixing.

Re: fuel

never heard of cooling fuel... can you point me at a product your speaking of? Thermodynamically it makes no sense whatsoever... the air is what you want cold so it's denser, but cooling the fuel is not going to make the air cooler because it will already be in the cylinder chamber by the time the two mix.

I'd say you've ventured too far into the electric supercharger isle...

Perhaps a fire prevention measure, or to keep them from vaporizing from the high heat of some seriously modified engines?

exactly, cooling prevents "vapor lock". You got to have a pretty stout setup to make it matter though so for a street car not real necessary.

You want your fuel cooler for the same reason you want your air cooler. It's denser. When fuel changes from liquid to gas as it mixes with air in the port, It has a cooling effect on the air as well.

I'd say you need to remove your foot from your mouth.

Re: fuel

Gee golly, I guess if it's on the internet, and somebody is selling it, it must create oodles and oodles of horsey power. Gee wiz, my mouf has sho got a foot in it now.

Re: fuel

These cool cans have been being made since the 60's. They are much nicer now then the older ones were.

I believe NASCAR has a rule that forbids teams from " artificially cooling fuel" As well. If you don't think they work, Go look at some NHRA Super Stock cars, They all use them.

Re: fuel

Still waiting on the proof... So far what I have is the premise that:

1) if it's on the internet and someone is willing to sell it it must increase HP and
2) if it's banned from professional motorsports it must increase HP
3) if it's been around since the 60's it must produce HP

Electric superchargers are sold on the internet and banned from Nascar, but I guarantee they will do piddly for you on the quarter mile. So what else you got? I'd settle for a dyno on a lightly modified 3800 or 3400 engine like what 99 percent of us have showing the before and after of a fuel cooler (without any other modifications).

And for the record, NASCAR engines have carburetors, allowing large amounts of fuel and air to mix well before the cylinder, thats just a wee tiny bit different than an electric fuel injection system that has its injectors pointed at the intake valves.


It sure is getting hard for me to talk with my foot up my mouth.

I suggest you do your own research and testing.

Re: fuel

I suggest you both quit your bickering and grow up a bit. Try things out and see how they work instead of going back in forth with the he-said she said BS. Any more crap and I will just delete all the useless posts in here. Do some homework and testing.

are you serious?

this has been around for almost 50 years, and most drag racers use them.

1. it has been around before the internet..

2. there are many things that are banned that increase horsepower.. think about drag racing, why do you think they dont use more nitro?

3. if it has been around since the 60's and a LOT of drag racers use them, i think it works

do you realize how hot intake manifolds get? by the time the air is getting into the engine it is already hotter than the air around it, and cooler fuel will help cool the air, yeah i realize this is happening at a very fast rate, and it might not make a huge difference, but EVERYTHING helps, drag racers arent willing to add a 5 pound fuel cooler to their car if it is NOT going to benefit them.

i dont know a ton about them, or the reasons behind them, and im not going to look it up, you are under the impression that they are useless, and it is some gimmick like the "tornado" so why dont you do some research like previously mentioned?

also guess what, when fuel is cooled down it compresses, which means you can fit more fuel into the engine, more fuel equals more air which equals more power.

im betting you will get false readings on a computer controlled car due to the fluctuations in the timing, etc

Bingo. That would probably explain right there. All the aforementioned BS being totally irrelevant, this might be worth a shot. Having taken a lot of chemistry, I came into this thinking, well if air is the limiting reactant, than how would denser fuel help? But that makes sense with the compression. I wonder if it would reduce det/pre ignition? Might be a smart move for nitro users.

I'm interested in this vapor lock deal. Fuel only burns as a vapor...its almost impossible to burn liquid gasoline. So why is vapor bad? Another gas volume/compression issue?

Re: fuel

nevermind. Apparently its a carb problem.

Re: fuel

Vapor lock is when the fuel turns to vapor in the fuel line, creating an air pocket. This in turn would starve the carb of liquid fuel and cause the motor to almost shut off. Moving the pump off the engine did allot to combat this. Fuel injection isn't very prone to this because of the lack of a heat source to the fuel.
