I'm thinking about going to a rear mounted radiator setup on my Evo and am trying to do a bit of research on it before I make the jump. There are two primary reasons driving the project, and a third that's a side benefit.

1) Prevent radiator from getting caked with mud in wheel-to-wheel offroad racing
2) Can't seem to get enough cooling (rad too close to the turbo assembly?)
3) better weight distribution

One of the things I know I'll need to do is add another water pump to the system. I was looking for the flow rate of the OEM system to get an idea of how large a pump I should be thinking about adding.

Thank you,

Dave

 

if I were you I would create a custom bypass all together for the stock pump, they caused me nothing but problems. and just go with electric

 

Great idea if you ask me devek! All the rally cross guys run rear mounted rads. As you say it helps with the weight distriution and ensures you get lots of nice coldair over the core.

I think the main reason the rad isn't cooling enough is the great big intercooler sat right in fornt of it! lol this is going to block some of the air getting into the rad. and aany air that dose pass through the intercooler will be nicely heated to! lol

Cheers,

Chris.
