The Secan is bar and plate, as are stock i think.
Jean has a Proto intercooler, and his is bar and plate, you can read a bit about it in his post on page 6 of the link i posted earlier.
I haven't seen pics of Jean's, but i know the 993 coolers you see on all the road going Proto builds seam to follow the Secan rule of thumb, front to back design, not too thick etc, end tanks are different though. I don't know what 90% efficency means to be honest, i think the only way to be sure your cooler is doing the business is to test it, Jean makes it quite clear that his isn't up to the standard of a Secan, and he races his 993.


Common Protomotive cooler, would love to see some actual data from one of these



Another shot of a Secan for comparrison
