Anders,
Go to this web site and down load the tech article on high speed gear lubrication. http://turbolab.tamu.edu/proc/turboproc/T33/t33-06.pdf
Interesting reading.

Hi Rex,
Very interesting reading indeed, and it somewhat confirmed my idea that the downside with post-mesh lubrication is acceptable compared to the alternative with all kinds of gear teeth damage.
If you consider the way the gearbox will work during a run it should probably work with injecting oil into the mesh, the gearbox will run from 0 rpm all the way up to 30.000/6.000rpm at the end of the run a couple of kilometers down the track so it will only see full revs a short while before I reach the end of the track.
Do you have a guess how much power I might lose on pre-mesh injection?
Industrial gears with 10.000h of life expectancy face all kinds of long term problems that I won´t have to deal with, I will happily change gears every 2 hours or so since that equals several years of racing.
Cheers!
