Post Transaxle mockup transitions to build

It was now time to figure out how wide the engine/transaxle package would be so that meant figuring out the bellhousing and transfer case between engine and transmission. Pete dug up a Ford bellhousing, it’s depth measured 7 inches and it had lots of unused “air space” inside. We could slice off the area making up the air space and go from there but that felt like a hack. Pete had some large billets of aluminum and decided to machine up a bellhousing from that.



For the transfer case, more aluminum billet was used.





You might guess that by now we’re transitioning from rough mockup into making parts for real. The outside half of transfer case shows this with some of Kevin’s nice CNC machine work.





You might also notice the mockup engine now has 2 heads on it. Pete found another core engine so there would be no worries about shaving off some metal and snuggling the transmission up even tighter.

As it turned out, the bellhousing and transfer case is about 7 inches deep, about the depth of a standard bellhousing. The transfer case still needs some doughnut shaped extensions on outside to hold bearings but these should be fairly thin. The length of the engine from front of damper pulley to outside of transfer case is about 33 inches. Even at 33” it’s going to be a tight fit into the chassis engine bay but we’ve made it as narrow as possible without going down to V6 or something. There’s no way we could have made a V12 this narrow.

I’ve got to give Pete Aardema and Kevin Braun credit and recognition for what’s been accomplished on the transaxle so far. Their talents are amazing and they’ve given the Miura project a huge shot of adrenaline. At this point, I felt we had enough engineering completed and information to know that the Strickland chassis would work. I’ve caught you up on project progress to-date and will give project updates more real-time as more progress is made.
