I finally found a good chart of the pumps were using and the new 90 series that I ordered. As you can see it is about DOUBLE the head pressure. This should overcome the restriction with in the water circuit on our cars. I feel that this should make a significant improvement especially with the parallel flow intercooler that I have been working. Enjoy, W

The flow difference is up to 4x the 30 series pump!! And 8 PSIG versus 5 PSIG is significant for sure.

The factory pump is rated at 20 liters per minute open flow, without restriction:
