Hi,

I'm a newbie here - just bought a Sapphire Cosworth running 25psi boost with appropriate fuelling, mapping and intercooling giving somewhere around 345bhp

My concern is that (to me) the standard rad looks very small compared with other turbo cars I've owned. Should I be concerned about cooling (especially if I do trackdays), and if so can anyone recommend a decent uprated unit that won't break the bank?

Thanks in advance

Kurt
