I want to put in an extra small motorbike rad in my s2 to help on hot days in traffic etc. Question is, how do i plumb it? Do i put it in series with the std rad? Problem i can see, is that bike rads have small bore's, which may restrict the flow? Or, do i tee into the cooling circuit, and put it in parallel? It might not get coolant flow then :S

 

just plumb it into the turbo water outlet

 

Does this work? Out of the outlet, into the second rad, then out and into the original rad turbo outlet?

 

Can't see why not. Pre-cooling the Super-heated water that comes out of the Turbo must have an effect.

 

As above, would just be a pre rad as in Cossie apps

 

 

Y - That will work OK .. just make sure the pipework is a good job!
I've also fitted them in the heater loop before (downstream of the heater)
That is also where aeration is definitely not an issue.

 

cooling the water/steam, using the turbo cooler from Pro alloy, that comes off the turbo b4 it goes back into the rad makes the WORLD of difference top mod

 

Just use a pro alloy rad the diff is tremendous and lots easyier and cheaper in the long run my temps are mint much better than the ford rads.
