Hello,

Do you think it is beneficial to run a fuel cooler then, almost a mini oil cooler size, after the pump, to help control and reduce fuel temperature. But to ensure you don't go to rich, add in a fuel temp sensor to then adjust the map to suit the density change. As the faster the vehicle speed, the fuel temp will drop, and increasing its density.

I guess this would be beneficial for prolonged high load application where you would normally add extra enrichment to help control combustion temperatures too? Decreasing the fuel temp to get the same effect?

We tried it on Evo, it works but only on high boost applications.

In most of the instances where I've been able to log fuel temperature, the range of temperature I see has not been that significant and hence I don't think there would be much to be gained with a fuel cooler. These do exist and are used so I can't say they're worthless but I'd start by getting an idea of the actual temps you're seeing and from there you can decide how much benefit a cooler could offer. Where fuel temp can be an issue is with over sized pumps that are flowing much more fuel than the engine is consuming - In this case the fuel gets cycled through the pumps continuously and heats up.

Thank you for the comments, i think i will look to add a temp sensor to the new system to see what is happening, then first look at if i can control this with heat shielding or a better sized pump (not over flowing). Also, i think the tank temp from fuel using our hand was more noticeable on the rollers, than probably what the temp is on the track, where there is less air flowing under the car.
