fuel cooler

[dracing70]

How effective is the fuel cooler and what does everyone think about just removing it??? Does it really serve a large purpose. I would imagine in race form the deletion of it would not matter much but when going back to street use is it needed if not subjected to extreme temps very often? What does everyone think or know????

I would ditch it for racing if toy have a good reason. Not just cause. DD it might be ok if it don't get to hot I wouldn't run the tank very low.

I can tell you I wish I had my fans hooked up on my setrab cooler when I was at the DPC. On the 4th pass fuel temp reached 350 degrees and I ended up running the 5th pass at 15k psi rail and the nitrous was still flowing

I would keep the cooler even though it does a half assed job.

I'm going to run both air dog returns to the stock cooler. I have a Fluidyne fluid cooler for the returns off the cp3's. My truck is for street use.

so you guys think a smaller fan assisted unit would work ok. Im trying to lose more weight and free up some more space.

The fuel cooler weighs what, 2 lbs?

Would a fan on the stock fuel cooler help when racing?

 

[juddski88]

The stock cooler is pretty restrictive anyhow. A Derale replacement and a fan won't break the bank. I will say I have yet to see anything as nice as the Setrab I bought from Mike L.

You have to weigh (get it lol) your options. Is it worth the lbs you'll save vs the hp you'll loose by removing it. For racing if you doing a lot of back to back runs with an almost empty tank it might be wise to up grade to something that would cool the fuel more efficiently. Think I read somewhere that diesel is its most efficient at like 150 F.

Pretty sure Cummins' study that is posted over on DP and maybe even here stated 70 *F was optimal

I think its a lot less then that, but there isn't much in the way of studies on it. I want to think I read it was in the 70*s back when Mike first started selling his coolers in a study done by Detroit.

If your looking for options look at spal google them they offer all sorts of fans that'll work on just about anything you can imagine if I remember correctly they offer 2in all the way up to 16 possibly even 20in or larger fans but I may have read that wrong on their site hope this helps

I can't remember where I read that, could be wrong for sure. It'd be hard to keep it below 70 deg. Just DD-ing temps get up to or over 100 deg.

Run your feed line through your ice box and forget about the cooler.

easiest way for a puller to do it right there:thumb:

I have thought about trying the cryo2 fuel cooler and tying it in to my existing system too

That is the dumbest thing I ever heard. Do some testing before you post this kind of crap.

Would it be best to leave the factory on or replace it? If I add one before the lift pump would that be to big a restriction or not needed?

 

[plowboy_lbz]

The fuel being returned from the motor has been super heated by being compressed in the cp3 and also secondary heat from the motor. The factory one is in the return so the returned fuel doesn't heat the entire tank. I don't so why you couldn't add one on the feed line. It would be a restriction bit idk how much.
