I run a HHR fan and Meziere 35 gpm electric water pump...Northern 2 row with 1 inch tubes...this is what mine reads at 96 degrees and hammering on it...I have since stepped up to a PRP-6660 50 gpm water pump but still yet to drive it...
Erik, did you like the Meziere pump? I have a Moroso drive on my stock water pump, but I don't think that even with the optional oversize pulley, that it turns fast enough. I am looking to upgrade.
