Thanks Steve, Cliff, & others
I've made up 2 different sized restrictors (12 & 16mm) and will test them over the weekend. Cheers
Thanks Ian for the input,
I forgot to say, on the Saturday before the race I changed the layout going into the block. I refitted the conventional side water branch on the block and connected the pump outlet to it directly, then took the flow out of the block via both the front and rear valvechest core plug fittings. I tested it with those pipes open running into the water butt, and the flow was even amounts from both. I then connected those to the rear and side fittings on the head.
I understand what you are saying about air-pockets, especially in the block where the original coolant passages have been blocked off.
The only way I can think of to eliminate that would be to fill the coolant with the car/engine on a 45 degree slope to give any air bockets more chance of escaping.
Thanks again for all the comments,
Sam
