[Fot] Close ratio gears

[Robert Lang]

 I'm not Steve, but I know why straight-cut gears are noisy! Helical gears simply put, make less noise. Helical gears also put axial thrust loads on the layshaft and layshaft thrust washers and that, as we know is a big problem with bit TR gear boxes.
So, the straight-cut gears are a win-win for a race car. You won't hear the noise and you get longer thrust bearing life...

 Hey Steve…
Just for my education, can you describe just what the noise is like?  (Not that it would matter in a race car)

Hi All,
Does anyone have a set of close ratio gears laying around for the TR4-6 gearbox they would be willing to part with?  They have been on backorder at all the suppliers and they keep moving their in-stock date further out. 
Thank you,
