Thanks for reply & info.

I read on another site they were considering deleting a couple turbos to shed weight. But still, 300# would be a lot of turbos!

You're right, I'm sure there's about as much alum & titanium as you can get in the tractor already. I doubt tires would shed that much either.

I wish them good luck. And-thanks again for detailed report. Maybe I'll get to see exhibition run somewhere also.
