I would think there might be a benefit of cooling down the Intake Air Temp a bit with colder fuel.
Either way, fuel cooling is pretty easy, but I just don't think there is any hard evidence it helps. In diesels yes, but it is usually to cool the fuel going back to the tank.

Quote from the Formula 1 rules:
6.5.4 No fuel on board the car may be more than ten degrees centigrade below ambient temperature.
6.5.5 The use of any device on board the car to decrease the temperature of the fuel is forbidden

I need to know what is the fuel pressure before the dampener and after the dampener and what would be the best location to install a fuel pressure gauge, my gauge goes all the way to 100psi. I also need to know more details on the OEM pulsation dampener, thanks.
I rather keep the project undisclosed to the forum until I do some testing of the concept on 1st Florida Dyno day, June 6th. Are you coming?

NB Miatas stock have fuel damper, not dampener.

Huh? Are you sure? I think it is the opposite. They are trying to keep the fuel as cool as possible, but in the rules there is a minimum allowed temperature. So they have to be careful not to run cooler than the limit. It is also forbidden by the rules to run fuel coolers.

[QUOTE=the_man;409469]I've heard arguments made for both heating and cooling of fuel. I have never, however, heard any hard numbers one way or the other wherein the temperature of the fuel was correlated to HP or whatever, without any confounding variables messing up the deal. Maybe one way or the other makes a difference, maybe it doesn't, but I somehow doubt that it'd be too significant or we'd see fuel heating/cooling devices on more racing cars and whatnot. Hell, if it was that easy/cheap to increase performance, we'd see it on street cars.

My Mercedes 190E 16V runs the fuel supply into a manifold that surrounds the A/C suction line, so when the A/C is running it cools the fuel down.
Not sure what their end goal was in doing it though.

Why not use what's already available?
Mr. Gasket Cool Can - JEGS
Fuel Coolers at Flex-a-lite Consolidated
I've only seen them on Diesel's or Drag cars, why the need on a DD?

Apparently I was incorrect in an assumption I made about the fuel flow in the '99, specifically the location where the fuel hit the regulator.
A much clearer set of images found in the parts catalog shows me that hte actual flow is from the pump, out to the fuel filter, then at the filter there is a tee, with one end feeding the rail and the other going back into the tank and hitting the FPR. This makes sense as you need to account for pressure drop across the filter, which I hadn't considered previously.
Here's a drawing I pieced together showing the complete system:

Because Hyper is working on a "fuel cooler concept" which is sooo much cooler (no pun intended) then just ordering something from the web!!
Personally, I think we should encourage that the brilliant entrepreneur SERerformance (Mr high compression pistons, remember?) and engineering genius Hyper get together. With those two master minds joining force, the potential for true epic failure (and amusement for us all) is nothing less then enormous.
