Nice to see that an 8.5 motor was quick enough for a result! His car looked good all day.

Cool, did you find that through google?

Car was indeed good, and 8.5 was ideal :)

Are you running a geared or ball differential?

I've been using a geared diff on high grip grass with 1,000 cSt oil and it's been great. But I was in Oswestry last weekend and the grass was destroyed and became a hard, rutted, dusty low-grip surface. I think the geared diff became a disadvantage on that surface.

I noted that two of the A finalists cars had their ball diffs running very loose, they could be heard slipping on the higher grip areas of the track.

Can you offer any words of wisdom about the two different diffs?

No, because I never tried a gear diff :-) And I can never run my balldiff loose, or it will slip before my slipper. Would be weird if the A final cars ran a slipping diff, sure it wasn't just the slipper?

Also, did you try thinner oil? Why not just put shock oil 50 or something in it, to make it very loose?

Well, slipper noise can be different from car to car and it's possible that that's all that it was. But I thought it was a definite "chirp" diff sort of noise rather that the common loose slipper noise. I may be wrong.
Food for thought though....

Thinner oil may be the solution, I'll experiment.. thanks
