Given the “free gearbox” change in the regs, I wonder if the restriction on ratio change on the sprockets is still necessary?

Thanks for the kind comments all! As usual the build has taken longer than expected, but it is getting close now and I can't wait to be back out.

Tony is of course right, standard diff, a chain off each side, then at the back, two shafts, one inside the other.
Currently I am geared 1:1, although I think under the 2019 regs I don't have to be, I'll have to refresh myself on them.

Also, playing devil's advocate for a minute, I can't see a diff test specified in the regs..... But everything is on bearings so should be no problems in reality.

I think you're right Peter. It would also make the final drive ratio easy to change on tranny cars.

An open diff is specified - they definitely tested the diffs after Croft last weekend!

Well after a week's holiday and no progress, I've got the oil and water systems plumbed, and the last checks on the engine sensors done, so yesterday was cranking for oil pressure, and setting the crank sensor position, and tonight she fired up for the first time!

I'm at the rolling road tomorrow... would anyone be willing to say what sort of max ignition advance I should be around?
Engine is standard bottom end, spec cam and mild head skim....
Thanks!

26 at 3500 rising to 29 at 7500 would be a good starting point

I'm sure we stretched to 32 on the rolling road at Aldon !!

On the mega jolt we set the red line at 8k with the advance falling off over the last 200 rpm to protect the engine .

I had a habit of taking it a bit too far in second and the valves complained :-(
