+1 on the tuning comments Bill made, Doug. At 1900 cfm your fan is a little on the wimpy side for your engine power level. You ought to be somewhere between half again and 2x bigger

A few years ago I ran across a company at PRI that had some stunning fan and water pump products. Their water pump was a 60 GPH unit and the demo was impressive in the extreme.

They also had fans that were every bit as stunning as their water pumps. Their 16" fan flows 3200 cfm. They also have 12 inch fans that flow 2200 cfm each and an 18 inch that flows 4100 cfm. The fan controller they use will ramp the fan speed up and down with changes in engine temp and provide you with a 1 or 2 minute run on after shutting the car off. The two 12 inch fans are a pretty small package with impressively high air flow.

If you want to do the mounting you can, or they offer custom made aluminum fan shrouds specific to the radiator you have for the fan(s) you choose. You do need to provide radiator specs and dims to them for the fabrication.

The company is called Delta-Pag and they are located in NY. The forum s/w will not allow attachments as big as the catalog so I am sending it to you by email.
