Can you mitigate it much on the throttle? Or are you in snapping drive shafts on landing territory?

It's always on the throttle on take off, even if it means slowing before to be able to boot it up the ramp, but no I don't dare try to land with the throttle on and it screaming, I think it'd smash the shafts or box.

Okay, winter plan #1 is in progress, build up that new gearbox we just got hold of with the short ratio 3rd and 4th gear, that should stop the car ending up out of vtec on a short shift/early shift on the bumpy stuff.

Slight problem. I need to hand file every single synchro tooth dog, all these little ones around the outside, for both gear pairs. Wish me luck...

I thought gears were hardened steel?

I always used cite sisyphus to describe repetitive mind numbing tasks... Think I have a more current example now. laugh

I've got yo ask...why the need to hand file?

They machined them wrong on the gear pairs, mainly because they couldn't get in to do them with their tooling, which would have been nicer if they mentioned it first. They're close-ish, but not right

Oh yes, it's going to be a long job, there's a lot of reshaping to do on the mating faces:

Ouch!

You can buy small diamond lapping slips and files in small sizes for all sorts of uses at moderate cost these days - that's the kind of thing I'd start with on b&stard-hard tool steel...

More positively though, after 10 hours of filing, you're gonna have the grip strength of teenage boy who's just discovered Internet porn.

If the hydraulic steering fails in the next race, you'll barely notice.

I'm gonna cut the bulk in with a small grinding wheel on a multitool, then I'll finish and blue it in with some little diamond files. It's gonna be fun...

Okay, not really any updates, I've been busy trying to find work and away over xmas and Ed's been busy finishing off a new car for a friend of ours, so the buggy's not had a whole lot done to it in terms of upgrades this time, for the first time in a long time!
The gearbox came back assembled, it's had a check over and has been refitted, there was some minor damage to the front of the frame from jumps and rough landings that's been repaired, the rear inner trailing arm bushes were completely shot but that's on us we were going to sort them out last year and completely forgot last winter - probably explains why it got rather tail happy on the last event or two as it was moving the rear toe around a lot.

Apart from that it's just been a service and a check over when Eds been there doing the other car anyway - it got taken out today to bed the new gearset in and 3rd and 4th are a huge difference, it drops into vtec even with a short shift for traction in the slippery stuff now and even lugging from down low off vtec feels much better as it'll pick up and go.

Hopefully now that means no having to drop to second just for 2-3 seconds of acceleration any more on tight corners, or leave it in 3rd and just wait and wait until it picked up its heels to go.
Second gear should just be for launches, steep climbs and hairpins now, 3rd will pull anything else outside of square corners and 4th is far more useful now for sweeping curves, whereas before it was basically for the longest straights only and maybe a couple of times per stage.

Of course, being straight cut the car's even noisier now hehe
