I guess I forgot, that is forgot to remember, that the truggies and buggies running the offroad races are running Mendeola boxes. I agree with you that they are quite strong.
Aside from the coolness factor, I am also looking for the ability to avoid the gas-guzzler tax in a small-scale manufacturer situation (the cost of testing and getting a series vehicle certified is astronomical, which is why Warren Mosler has not re-certified the MT900 for the LS7, simply because the amount of roadcar to racecars built is negligible) as well as driveability and yes, the cachet of building a series of bona-fide 200 mph+ streetcars. I wouldn't care to drive a high-revving multi-cam engine or even a torque-monster V8 to 200mph with "only" a 4/5 speed. I can't imagine that the engine would like being near redline for minutes at a time on a full-speed blast. With a race engine, that is another matter entirely. Most race teams build a new engine for every race. How many owners of exotics would care to buy a new $45,000 engine every time they "exercise" their car on the track?
I can appreciate for the needs of all the GT40 enthusiasts and builders, that a transaxle that fits within your chassis and bodywork is a concern. For the rest of us in the kitcar/replicar/exotic car world, only having the choices of a transaxle that will fit in the GT40 is annoying. Aside from the XTrac 6012 and the GearFox T750/T900, there are no "off-the-shelf" gearboxes available. The XTrac is being offered at $25,000 per unit. I have no idea how much the GearFox box is going to cost, but I estimate around $20,000 per unit. Converting a Porsche gearbox offends my sensibilities as a potential manufacturer, not to mention has it's own downturns for a production car (ie, driving the ring from the coast side, rather than the drive side, due to flipping the unit for mid-mounted use). I went through an estimate & analysis with Tremec regarding the design & production of a series of transaxles using repackaged T56 internals, and my costs were still going to be almost $20,000 per box. A gearbox being offered in the $11-13,000 price range is much more reasonable, considering the price for a crate LS7 is $12-14,000.
I really do appreciate the feedback on this forum. I too love GT40s, but my initial reason in joining was to find alternatives to the ubiquitous ZF and Porsche transaxles.
