You are correct ??? the dimensions were overall!?? The measured fin area is 12.25??? wide, 17.75??? long and 2.5 in thick = 543 in.cube.

My invoice from Summit?? in 2016 shows a part number GRI-2-58185-X?? cost $295.95.

The new part # may be 2-56185-H.

The James cowl I used has the air intake under the spinner.?? That is why I mounted the radiators under the motor mount!

I ??do not know if they still make this cowl.?? I once heard they moved and did not take the mold with them.

Thank you Dennis.

Are you sure those are core dimensions and not overall dimensions?
Do you happen to have the model number of that radiator?

What did you do with the openings on either side of the spinner? Or is there a James cowl version with only a big opening under the spinner?

Finn,

Sorry for the late reply to your 9/7/19 post.

I used a James cowl on my RV 7 A with a Renesis 4 port.???? My water ??radiator was a Scirocco drag race radiator ??? core measures ??13 in wide x 22 in long and 2.5 inch thick for 715 ??cubic inches.?? For the oil I used a stock RX-7 oil cooler (2.0 inch thick) with the bypass plugged.?? The radiators are mounted side by side under the engine motor mount.?? The aft end of ??the radiator assembly is against the cowl bottom and the radiator assembly is bolted to the motor mount structure at a 30 deg angle with the high end just above the James cowl air ??inlet under the spinner.?? ??The air flows in under the radiator assy. up through the rads and out at the firewall.

??

I cut a small opening above the James cowl ??cooling air inlet to use for engine combustion air.?? In the cowl under the radiator assembly I built a pinched duct to try to distribute the airflow evenly through the radiators. (Probably could improve it)???? If it is real hot when I takeoff I reduce throttle as required to control my oil temp to not exceed 220 F. My water temp is usually 10 deg cooler than the oil temp.?? I have taken off fully loaded when the air temp. was 105 deg F. and climbed at 20 inches manifold pressure to control temps.??

??

I have about 860 hours on the engine.?? The doner car had about 9,000 miles on it when it was wrecked.?? The engine has never had the rotor assembly taken apart.?? Most of my flying now is 10 minute flights from 40XS to GTU to play tennis 3 - 4 times a week.
