Finely looks like I’ve got the cooling sorted
But I need to get a bigger fan!
Im using an 11” fan on a polo rad that i got from tiger but I looking for a 12” fan as the 11" seem to be struggling
Dose anyone have any recommendations??

Or how about 2 smaller bike fans?? Bigger overall surface area.

What engine are you using??
The fan obviously only works when you're stuck in traffic so the fan size will depend mainly on the amount of heat the engine gives out at idle.....
I'm using a Polo rad and a Honda blackbird fan and no over-heating yet....

im using a pinto with r1 carbs
