Cheers for the replies guys!
I have found out, with the raceline water rail, there is no bypass, but a 2mm hole drilled into the thermostat to act as a bypass when the engine is cold.
I know that the 2 small outlets on the standard house do the heater and the bypass, and that the small one on top is an air bleed! So, tomorow, The stat is coming out, a 2mm hole going in, and the heater and bypass are getting blocked! Unless thats not going to work either
Cheers again guys!
