Awesome to hear. I was thinking of just plugging the bleeder since my car is really low and I don't see much point for it for this application. I'm glad to see you guys are still using it trouble free
Are there any differences between cooling efficiency between the tube style and bar and plate?
Yes many differences. Google "differences between bar and plate vs tube fin" and you'll find a ton of intercooler links and various turbo sites mainly. Lots of results will return that show you pros and cons of each.
With my last Cobra, I was going to go this route.
Then, I got a wild idea...to just find a used GT500 AFCO H/E.
I mocked it up, and made it work. It performed very well.
