hello, i have a pro alloy FMIC an my ACT's at 30 psi are 65 degress which is far too high,

are GRS front mounts a lot more efficient?

or what is te most efficient one, im not bothereed about having to cut out a bit of the front end to fit one but would prefer it to not be on show that much, cheers

 

Having had my GRS for around five yeras now, I can say that the ACTs pretty much always equal the IC temperature. How much above ambient they are depends mostly on heat soak from radiator and slow car speed. highest ACTs can be seen when cruising slowly, not on track days.

 

Bit of a discussion here Andy.

ordered a GRS

 

That's what i'd have done too

 

an efficient cooler does not always mean lowest acts,
grs has the lowest of the on the shelf coolers,but efficient it is not
