Anyone done a direct comparison? In an aid to tidy the engine bay ups had make some space I have looked at pusher fans.?

What's the biggest size fan I can go to. My car doesn't have ac anymore,

Anyone using one?

Thanks reuben

I'm using a pusher on mine, but this was for the purpose of getting the manifold to fit. I'm running a 12" Spal fan and have no issues with it keeping temps under control.

Thankyou begbie.
Exactly the answer im after.

I assume the radiators are of simular size on the 20vt to 16vt and 12" is the right one to go for

The radiators are all the same sizes on all the coupes, just different inlet / outlets on them. 12" was an accident by me, as I used to run a 13" Spal pull fan, but ordered a 12" thinking it was the same size, when it wasn't

You also might run into issue when trying to fit it as well. In the end, I used the rods that you push through the radiator fins and have clips on end.
