The plan all along has been 600 MY2008 and 600 MY2009 so yes that seems reasonable. Many have discussed that here and that plan was deemed quite reasonable.
It is my understanding that DT1.5 has been fully tested and and is due to start being installed in cars VERY soon if not already. I think it may be being installed after car 38 if my recollections are correct. So 1200 would be fine...
"the plan", "my understanding". Hmm.
They've made/delivered 38, & they intent to ramp up to 1200 by next Sept?? Man, I think that's a big jump, especially for a 1st production line. They've never been in this territory of big production #'s.
I never heard anything concrete from the Death Valley test, & where are the #'s for a Durability/Reliability test? One more snafu with transmission, that's it. People have a finite patience threshold.
An Xtrac development partner (offroad) went thru several cycles of prototype/race/post-mortem (lots of breakage over 2007 year) to develop a 2008 tranny which has scored 1st, 3rd, 1st. They are 2nd in points going into the Baja 1000, looking to take home the points championship. They started out with an Xtrac tranny with a Formula 1 style clutch pack (7" diameter), & beefed it up to withstand offroad abuse. The latter is similar to the shockload of a Roadster w/AC Induction Motor (instantaneous power, severe shockload to tranny). Apparently, there is a near-solution for a Roadster 2-speed Xtrac, with some modifications (cross-over technology transfer from offroad to pavement). The Durability/Reliability test has been done in offroad racing. Beautiful demonstration of the power of Interdisciplinary Science. I've been in touch with those parties (VP of Xtrac, owner of offroad partner), & it's simply a matter of writing a proposal to do the technology transfer. That's where I would get involved, getting a Roadster & doing the mods.
Imagine the performance with JB's PEM modification (complete overhaul from analog to digital), plus a 2-speed.
