Cheesehead
Are you on the list that has done the Eaton swap on your ride ? Would you say it's better than the trilogy set up ? Or is the eaton set up better in the long run because part can still be found and made for it ?
Sorry to bug you with questions and also sorry if thus sounds dumb .
Yep, I've got an Eaton swap on my car, and, no, not a dumb question at all.
I would say the Eaton swap is in no way better than the Trilogy, but it was definitely a lower cost alternative when Trilogys were still being offered. Now that Trilogy kits are no longer being sold, options for roots-type blowers are limited, so to a large extent, the "Eaton swap" is the only game in town. (Even if planning to install a Whipple or Kenne Bell, you've got to use some of the Cobra Eaton parts as a basis).
Actually, both the Cobra Eaton and the Trilogy blower head are M112s, but the Trilogy set up uses a different plenum design that allows driver's side air intake, which makes it a direct replacement for a NA set up. The Cobra Eaton is passenger side intake, which requires relocating the battery and some other peripheral components in the engine bay.
Also, the Trilogy was a complete kit, everything needed to convert from NA to S/C was included in the box, ready to bolt on; whereas the Eaton swap requires you to round up the used OEM Cobra parts, new OEM parts from Ford (if used ones can't be obtained), and aftermarket parts (such as the gortch brackets) as well as fabricate various other brackets and such. I found that part of the project to be a lot of fun, but for some folks, parts chasing is a PITA.
If they still offered Trilogys, and if I could afford one, I'd buy one in a heartbeat. That said, I love my Eaton swap, and don't regret going that route.
Bottom line: Whatever FI system is chosen, Can't Beat Boost!
