Extra radiator Options

[yellowchinaman]

Can anyone think of a down side of adding an extra smaller radiator to work in conjunction with the stock radiator for extra cooling? BMW's are doing this for the 1M.

I have been reading your stuff over on the DC I think it was.

The only problem I can forsee is bleeding it.

Another option might be to add a small oil cooler type radiator on the turbo water return line as that will be very hot.

The trouble with cooling the water too much is that it will just close the thermostat and restrict flow and could in extreme conditions lead to thermal shock which I guess might be unlikely, but do remember datajon mentioning something along those lines and as he builds race engines for a living I guess he knows what he is talking about.

If you look on the OC for a thread of mine titled something like "How to improve the cooling system" there is alot of detail in there and some ideas from DJ about what he would do to improve cooling. The addition of another radiator to the main system never came up....if the main radiator is up to the job then I dont see the point. Cool the water too much and as I said the thermostat will just close and you have little advantage.
