Moose ,

As you will know there are differing opinions on the GRS coolers with people saying that they enduce pressure drop , i dont know wether this is due to the cooler core design or the end tank shape , i know that the way i do mine ( single pass) there is no drop at all , i will at some point get round to doing a twin core cooler , single pass and with a end tank design to encourage smoother air flow .


PS u still doin polly bushes mate ???? mmay have another set off you . S2 RST
