$10,000 would be nearer to the mark for the small ones. $100 is very very castle territory even at 20,000 unit batches. Well north of a couple of grand atleast. As for BP then yes they will buy them and if the service life checks out they would pay $20k a unit as it will save them in downtime on some oil rig in the middle of the oggin (or under it going on thier past record).
Less material, might want to see one in the flesh, also a much higher grade than standard crap metal thrown in CVs with much more machining required. Safe baah who gives a rats about such a insignificant part on a bombadore, far far far more likely to focus on interior trims or altezza tail lights before mechanicals.
Until Thompson join forces with a major gearbox/transmission/power transfer company to offer intergrated powertrain solutions then they will be a wall decoration. As for challenging the Voith-MTU-DetroitDiesel-Allison alliance...... good luck.
