[DeTomaso] ? Fwd:? So . . . .

[Ken Green]

What usually fails in a transaxle?  I think Esekof (SP?) was busting the ring & pinion.  If that is the common failure, a light car should be OK because in low gears, traction would limit the torque through the gears, and in higher gears, the amount of torque to ring & pinion is reduced by the gearing.
 
If you're busting input shafts, I guess all bets are off.

Durability is relative to power in any engine and running old school NA V8's (even Chebbies)at 720HP is not going to provide 40K of trouble free miles. I've been told to expect 40 hrs hard track use before pulling the engine for a freshen up.



For that reason the now favored Ultima powerplant is an LS7 (often upgraded with the addition of twin turbo's).



Porsche G50 transaxles are very durable, with the correct upgrades (billet side plates and spray bar oiling system added), I haven't heard of one Ultima grenading a transaxle.


BTW whilst on the subject of transaxles the new ZFQ can also be supplied with a bellhousing to mate to Chebbie. The street version is rated up to 600HP and a track version with dog engagement & straight or helical cut gears is now available. Current exchange rates make it an absolute bargain at GBP6500, which is a tad over US$9K.

There is quite an active club in England where they're built. I remember 
Ultimas running against the ADA Pantera in the British Drivers Club roadrace 
Championship, the year when the 'old' Pantera won that series. Ultimas are fast 
('cause they're light) but seem to have durabilty issues just like Panteras, 
possibly more with the poor overpowered transaxle that gets adapted. Maybe a 
slushbox makes sense.... J Deryke
