Long overdue update.
Wasn't the gearbox that broke, it was the clutch plate. Apparently a much too aggressive clutch drop on a down change caused the plate to buckle and destroy itself.
Replaced it with a near-new clutch from my GE Sigma motor.
Also bought and fitted a set of lightly used MCA Purple coil overs.
And ditched the extractors and replaced them with a stock manifold and downpipe to meet the rules.
And on Thursday we took it to a track day at Wakefield Park.
It went really well. The MCAs are great - they just work. Made some improvements to handling by fiddling with the alignment - I'm sure that there are further improvements to be had, but nothing stands out as being wrong.
Clutch slurs on the 3rd to 4th gear change, so I will need to bite the bullet and buy a decent one.
The shifting of the new box was no better than the old box, but the rubber shifter cable bush fell out at one stage - I rolled from the back straight almost (almost!) all the way back to the pit garage. After bodging it back up with a big washer, the shifting was much better.
Also spent quite a bit of time trying different lines and pushing myself to drive better - both were reasonably successful, but still more to be had.
Ended the day by punching out a succession of mid-high 1:18 lap times, with the best being a 1:18.44 which would have put me about 2/3rds of the way down the grid at the most recent Excel round at Wakefield.
I am happy with this.
The Excel lap record is 1:15.3, so I will need to find about two seconds to put myself in the fast group. At this stage, I feel like those two seconds should be relatively easy to find - but time will tell! :)
Next step is CAMS logbook and me to get proper racing licence.
