I don't think I can agree with the '3 major reasons to install a fuel cooler' in the original article:

1) Reduced diesel temperatures will reduce temperatures inside the engine.

... well possibly, but we are injecting MILLIgrammes of fuel per stroke, so making that fuel ice-cold isn't going to make a vast difference to a massive lump of cast iron.

2) ... under spirited driving or track day conditions you'll easily get fuel temperatures in excess of 80

Some very valid points Bryan

Biodiesel doesn't appear to be publicised (sp?) around this area, and although I am very much interested in doing some blending etc (I've read up a fair bit on it, including many of your posts here and elsewhere on the subject), I just haven't got the right property to do this. First floor in a flat, that kinda thing. If we move I will probably switch to a blend of biodiesel and I am quite sure it would reduce smoke a tad etc.

I've got CC1 + propane at the moment. It needs CC2 or CC3 or equivalent which will probably reduce temperatures on the fuel side of things.

Adding extra cooling capacity to the fuel system (without changing how the temperature is regulated) should allow the temperatures to stay nearer to the 72 degrees mark (for longer).

One of the most valid points is that the air intake temperature is probably more of a factor and annoyingly there is very little you can do about it in the vRS :(

Oil cooling is another thing I'm considering, would need a thermostat to ensure the engine warms up asap though

FMIC? :confused: Probably about the best thing you can possibly do to cool down intake air.

Hmm yeah you're right of course, the FMIC helps, but I meant more the bit pre-turbo, like a CAI, which is a little tricky in the Furby IIRC.

The outside air temp going up causing performance to go down a bit is unavoidable even with FMIC. At 30 degrees outside temp the FMIC helps prevent heatsoak caused by the turbo boosting, but the air still won't be as dense as when outside temps are say 15 degrees

You could always wrap the intake system (pipes etc) with some heat wrap stuff. Think Andy Ellis did this acouple of years ago. Do a search he posted it alll on here

I just might Thanks

Going a little fanatical about trying to keep/get temperatures measured & within as-close-as-possible-to-standard. Bit like OCing a PC, keeping it close to standard (or colder) works well for that, for cars too cold is usually bad too though

As a result of that little comment Neo_vr made in the different thread started on this site, it's got quite interesting (to me at the very least) so thanks everyone so far for the responses & links

Excellent, thanks
