Fuel Cooling?

[riceline]

hey guys

I have done a serch on this and found a little bit of info about it. But not enough!

I have done a serch through www.capa.com.au and they recomended that there oil coolers are also able to "make a great fuel cooler to". Found out that the Range Rovers - Bmw's etc etc also use a fuel cooler.

Now this got me really interested so off I set to super cheap/repco etc etc They have got off the shelf Transmition Oil Cooler kit for 6cyl cars. Would somthing like that be suitable for Fuel cooling? Next time im back there I will have a bit more of a look for what pressure it can take. Unless sombody has an idea as to what a tranny usally runs at pressure wise.

Any extra info would be great guys

Take it easy

Try asking SydneyKid, Warpspeed... I remember a thread about fuel coolers, and am quite sure they mentioned some interesting points. If I recall correctly, they mentioned some mob from the US that sell these "esky" type things for your fuel/fuel pump.

I know you said you did a search but maybe try agian.

hey mate

I looked at the "esky" type thing and i really dont like the idea of having to carry ice around everywhere I go. I would much rather have a more perminant solution rather than somthing just melting away. In that thread they were talking about the BMW one that could be modified to suit and mounted somwhere in the frount bar.

Hi riceline, fuel runs at ~75 psi so you need a cooler that can hold that sort of pressure. Auto transmission or power steering coolers are not really rated for continuous use at that sort of pressure, from what I have seen. So I would reckon an oil cooler would be the most likely option. Maybe have a talk to Martin at Earls (www.earls.com.au) he has lots of experience with coolers.

Before you go ahead, I would strongly suggest you measure the temperature of the fuel going into your engine and compare it with the ambient temperature of the day. You may well find it to be a waste of time. That's why we use the ice cooled method.

fuel has a flash point of somthing like -23 deg i cant see any point in cooling it. For a daily driver that is.

Its cooled for the same reason you cool the air with the intercooler. The colder the charge the more dense it is, so the more pressure differential at combustion, so the more power produced. (And all that boring detonation stuff)
