Cooler Fuel Temps

[beingblueeyes]

there was a member on here who made a fuel cooler out of a block of alm. and tec's and if memory serves he was trying to market it but that was a long time ago and nothing new has been posted about it so i think it didnt work out. cant recall the guys screen name

It worked! marketing stuff is slow though. I recently went to work for a R&D company, so things are moving forward again. I still need to get another unit ready to send to Nelson Performance for some testing.

With fuel at 80dg F, you'll see 13-15dg temp drops with version 1 but it takes a few minutes to reach peak efficiency.
Unit 2 was showing a 34dg drop after 2 minutes run time. The unfortunate thing is that with a fuel system with a return line at the fuel rails, you end up trying to cool all the fuel in the tank as is circulates. a returnless system would be ideal with the cooler hooked into the pressured supply to the rails. That way your not constantly recirculating fuel.

With a returnless system what is the average fuel consumption? The reason I ask is if the fuel went out of the cooler how long till it makes it to the injector, and how much of the temp drop has been lost due to the time it takes to use the fuel?

Im not trying to say it wont work, I just wonder how well.

I'd like more details

Wrapping the fuel lines in insulation of some kind would solve all of that. I have some 1/4" thick Kaowool insulation that is used for doors on forges and other really really really hot things to insulate them. Something like that would work well with a mylar shield around it.
