Fuel Cooler

[wmax351]

Just picked up an oil cooler from a honda nighthawk off of fleabay. Going to make it into a fuel cooler, which should solve the problem of boiling gas in hot weather.

Now that sounds like a plan!  :2thumbup:
How do you plan on hooking it up? To the return side or before the Injector rail?
Please keep us updated and post lots of pictures....

I'm figuring I will put it on the return side, though it may be easier to plumb in on the feed side. The goal is to keep the whole tank cooler, rather than cool it pre-injection, so it really doesn't matter.

The return side sounds like the best side to me also. If it works well for you, it maybe a winter project for me this year.

I was gonna mount one infront of the radiator... butts I didnt cause I thought the heat coming off it would melt the solder in tha radiator...

Hi Gang.
I'm guessing but would it not work to mount it to the right side away from the exhaust and heads?
I would think that mounting it just in front of the lower right side fairing port would give it good air flow. (on my K100LT anyways)
If mounted on the left side it would catch heat from the heads & exhaust pipes I would think.
But this is just guess work on my part. I have not seen the oil cooler that WMAX is going to use or know the specs.

Still looking forward to see how he does it and how it looks!

im mounting mine above the front fender between the fork tubes and using those race car flexableb braided lines...

I am happy with my fuel rail/regulator cooler. I took air from the LH fairing duct (NACA),and collected it in a box with the regulart in it. A tube then ducts it along the fuel rail. This made a huge diffenence in the Georgia summmer. I posted pictures somewhere in this website.

This fiberglass box collects air from the left NACA scoop and directs it along the fuel rail tube. The fuel pressure regulator is repositioned also.The cover for the collection box is off to show the arrangement. The fuel tank stays cool now...finally. (The picture needs to be rotated 90 degrees  clockwise)

Your concept of "hot running" is biased.

I had great fun with those silly Rotary engines!

I had a '79 RX7. What a hoot. 12 MPG of fun.

Remember the rotary powered pick up? I have never seen a small truck that that would shoot from zero to seventy any faster.
I bought one of those for $400. It was a blast to drive but looked really bad because the paint needed a lot of work. The PO had not maintained the paint in years. I remember walking out my front door one morning and finding out that my next door neighbor had washed, waxed, and buffed out HALF of the hood!  Of course I could not leave it like that. It took me ages to get the paint into decent shape.  I don't recall what practical joke I did in return.

That had the 3 rotor 20B engine. Lots of power.

I had a RX7 at one time. Big follower of the Mazda Rotory IMSA entry's.
I didn't think the US ever got a 20b production vehicle. I thought everything that the US got was 2 rotor.

[wmax351]

I know I saw one 20b pickup on CL. Maybe just a fluke.

I think mine had a 12B or a 13B motor. Smoothest running vehicle I have ever owned(except for the K bike). It also used more oil than any other car that I have ever come across.

Very smooth indeed. It actually has a pump that runs engine oil into the intake for lubricating the apex seals. I actually ran some 2-stroke oil in the tank, and the cars should have had a designated 2-stroke oil tank to feed that pump, and it's a common mod to do that. I was going to do that, but sold it before I got around to it.

Hey wmax,

Did you ever get the fuel cooler mounted and working?
If so would you mind posting some details and photos of the project.
Heading into the warmer season here and would like to be able to see if you got it done and if it helps or not.

Thanks!

I still haven't gotten around to it. I may do it early in the summer once I finish up at Cal, taking too many classes for my last semester. I'll keep you posted.

Thanks,
Looking forward to your results.
