cosrush - have not fitted ally rad yet cos i just took the motor apart (didn't need to really but kept me busy and out of the supermarkets and furniture stores for the winter lol - now 7.2cr cosworth pistons / ported head / greys/ t35 - t4 / cams / long studded block etc ) done 100 miles so far! when its done about 500 i'll put the other rad on but to B honest i dont think it will help a lot. my car was only running about 300bhp last year and on the really hot days the thing was cooking. still say that the air flow through the rush bonnet is the problem - in theory if you have a 2 litre mega turbo car idling it shouldnt run any hotter than a 2 litre non turbo but of course just after you have slowed down you might have shed loads of heat around to dissipate. anyway the rad still is much smaller than most 2 litre cars' (and you cant get the airflow throgh the engine bay|)
