I get that part, I also have a game plan going into a race and it can change due to ALL the track conditions as well. I can pit early or late. If I'm doing good in the first 1/2 of a race I will push it knowing in the back of my mind that eventually I will need fuel, I keep it real. I most certainly will NOT give credit to a piece of aluminum in-between rubber fuel tube to cool the meager amount of exhaust going into the tank for longer run time That's redonkulous

Simple solution to end the debate...

Someone invest the money in a wireless temp probe and stick it in the fuel line about 1/4'' just before the carb inlet needle to measure the temp going into the engine. Do it without a cooler, then cut the fuel line and stick a cooler on, same setup back-to-back.

It's gotta' be worth the $500 in testing to gain those 20 seconds.

I guess I was looking for someone to explain how it cools if the exhaust is static. I don't think I will pick one up because I don't think it is possible for something to be thermodynamically cooled if there is no flow. They do look pretty snazzy though.

to those who are racing for money it may be worth it, but until then i like to keep the racing fun and just a hobby. when the argueing starts is when the hobby begins to be............well....not a hobby

Has anyone felt if the cooler is actually warm to the touch after a tank?

Better yet, have it part of the TELM. sys, read it on your TQ.


Nah, give me the $500 and I'll run faster & leaner. $500 could get me 10 pinches and a couple of new sleeve's

I'm no pro. Pro's come off the track at 320-330, run so lean they get the extra min. What do they care I could act pro with a extra $500 in the hip...

Yes it is and is more than warm One of my mates thought that it can't cool anything so he tried to touch cooler himself after run.

Even simpler. Shoot the temp of the fuel in a near empty tank at the end of good run. Once with a cooler and once without. This is when the cooler would have presumably made the greatest difference. I have not done this but my experience tells me the fuel is cool to the touch either way.

Please let us know how the testing works out for you. I'll be one of the guys on the stand making 43,000 RPM noise out on the track

I'm not doing any testing. I wouldn't install one even if it did add 20 seconds. I hate leaks.

We already know it does not change rpms, that fuel does not condense like air due to such slight changes in temperature, that no other form of motor sports relies on chilled fuel to increase performance and that no car or truck being offered today makes claims of increased fuel economy resulting from a fuel cooling feature. I think of fuel line coolers as one of the ultimate rc bs products supported entirely by our addiction to try to build better.
