[QUOTE="mandkole, post: 1431131, member: 4630"] Id say the coolant temps are driving the cap pressures for emissions. Don't they want them running 215F or so? Im familiar with some heavy truck engine programs and they have pressures on the top tank that may approach 45-50 psi.. its due more to coolant flow rates, but theres some heat gain as well. [/QUOTE]
