[DeTomaso] Tran Fortin 5-speed in a Pantera - Photo Attached

[davek]

Julian, Steve,


FYI, there was a Pantera at the Phoenix Fun Rally with what I believe was either a Fortin or Mendeola gearbox. It looked like a nice tidy installation. Attached is one of the pictures I took at that event.


The ADA Pantera raced in the '90's with a 5-speed March gearbox. I had sourced a 6-speed version of the same, but these may be hard to find.


Going back further, there were several race Panteras which ran Hewlands. But none, as far as I'm aware, that were homologated for Group 3 (which sounds like is the objective).


Regards,
Dave

I believe the reason that Quaife has not offered a Pantera variant is because it's not a simple flip for the crown wheel & pinion with the inversion to run upside down. I suspect if it was "easy' they would have done it by now and yet all the folks that I know who inquired were told there were no plans to offer a Pantera variant. That said you could try and run it in the GT40 orientation with the input shaft over the output shafts, it would sit higher or provide opportunity to lower center of gravity by dropping the engine, that is assuming you can do that without modifying the frame rails or losing the oil pan on the asphalt!


There are also a number of failures reported on Quaife transaxles on GT40s.com when used hard under racing conditions, although that might have been solved with later production. Even so, I personally think the real ZF is a better option than a ZFQ and if it were me I'd have the existing ZF inspected and rebuilt with appropriate ratios for the tracks run. Of course you never get the flexibility a true racing box like a Hewland would offer in switching ratios out to specific tracks, the compromise option might be to have 2 ZF's one with ratios for long and the other short tracks. My ZF was in and out so often at one point I could do the switch on my own in under 2 hours.


Given prior discussion on homologation and meeting 1973 specs etc. I expect you would face some backlash from the sanctioing body on using a modern transaxle. That said I think the later ADA Pantera Si ran in the 80's with a Hewland, so maybe that is an alternative?
