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.

Increased drag on the waterpump. You wont notice the difference but the water pump will consume more usable horsepower.
I would add it to a different circuit on the cooling system, maybe in line with the oil cooler rather than the radiator. If you think about it your heater-core is a small auxillary radiator, with a blower fan already attached. If you are looking to cool the engine, you could also upgrade the stock oil cooler. Your oil probably runs anywhere from 200-350 degrees and up to 500 in racing applications. Bear in mind that the hotter the engine gets, the more powerful it becomes. The fuel atomizes better, but more importantly the oil viscosity thins out with temperature. Measureable gains can be netted by using a thinner viscosity oil or allowing it to get hotter so as to thin it out. |

Tapped into thermo sandwich plate and located to front high beam inlet. So now I'm thinking, is a swirl pot and tank a worth while mod or not because it's only going to speed up cooling when needed. Maybe instead, use a small rad for improving the charge cooler so that inlet air is cooler? Maybe that is a more worth while mod? This post has been edited by yellowchinaman: Jan 11, 2013 - 9:15 AM |
