Hi Guys

Wondering if people know what pressure is bing pushed through the cooling lines? And more specifically what that pressure is on a R3 reflash?

Looking to upgrade cooiling lines in preperation for new intercooler and reflash but don't want to go overboard on the pressure rating as the lines get stiffer and harder to clamp. Would 150psi be to little or enough?

Also are there any other size hoses used apart from 1/2" and 3/8"?
