Stock Elise /exige rad capabilities ?

[mighty kitten]

I wonder how the stock rad copes with higher power outputs ? I have an ongoing issue with my car that is sort of fixed by running an electruc pump at the front to keep the coolant flowing partly due to the rad being quite tall and bolt upright . I had a nose round some cars at a track day at cadwell last weekend and the stock item looks like it will fit and as its around 6 shorter height wise I can lay it back quite a bit giving the engine pump a much easier job . How do people go on with 400+ hp cars for cooling ? Tia

Engine is in the back and the pipes are 32mm running down the tunnel with a Davies Craig pump on the rad inlet and control unit with sensor in the cylinder head . The issue is flow as it works perfectly on track days keeping temps to 90c no matter how hard it's driven but without the pump it just pushes water out of the header tank after you let it idle after a session . I've got room to bring the lower edge of the rad forward and down by a few inches and then lean it back to lower the inlet which is how the lotus rad sits from what I can see but a less tall rad would obviously lean back a lot further

Rad has top and bottom tanks so being vertical the engine pump has to push the water up to the top of the rad where the lotus sits a lot Lower in relation to the engine making the job a lot easier . Twin fans in a sealed shroud and I run an 82 degree stat in summer .
