You just about need the handbrake at that place!

in the lower gears at lower road speed it is beneficial to use the clutch on the gear change to avoid blazing the tyres on the change......if he flat shifted from first to second while still turning out of a corner i could almost guarentee he'd end up facing the other way.....when using the clutch you can add a lil more progression the the delivery of powerI also noticed he would use the clutch once while up-shifting/accelerating when first coming out of corners, then just slammed thru the rest of the gears without clutching ? Why use the clutch for the first shift and not the rest ?

But the reason MS would use the clutch on the 2-3 shift is because these boxes are setup with a "strain gauge" which is linked to the ignition cut circuit in the ECU. What this does is momentarily kills the engine when enough strain is placed on the shifter handle. ie: pull hard ignition cuts out for a split second allowing the next gear to be selected without lifting the throttle at all.
Remember they are dogring transmission and NOT synchro so they shift in a split second, but you still must somehow remove the load from them.
It takes longer to do a 2-3 shift than say 1-2 or a 5-6 so MS is just being safe and ensuring that the gear is fully engaged and he doesn't have to rush or risk "falling off the shift cut"
The same thing can be achieved by "banging the limiter" on the upshift....
As for overrevving on a missed upshift????
How you do that is beyond me, the ecu is in control and sets maximum RPM on the way up the revrange.
On the way down however is a different story! It is very easy to pick up a gear too low by selecting the wrong gate... and then the egine revs are being controled by the cars road speed, not the ECU.....
The result......
usually, if the speed is high enough and the gear low enough... KABOOM..... valve train in the sump!

as for the overrev.... that's not what the data from my data logger would suggest!
Must be a Very old system that your referring to.

That's the one Greg. Also, not really having driven the track before and trying to post a good time. Arrived at the tight hairpin at about 80 km/h. Firm brake, mash accelerator, flick.Thinks of Wakefield park hey Yella.....
You just about need the handbrake at that place!

I know it's a lot of jargon , but there really is no easy way to explain it!
Sometimes it is just simpler to hit a curb, get 1 rear wheel in the air, which unlocks the rear so the car turns better (like a go kart)

The printout I saw was from the Perkins 95 Bathurst winner after practice at Oran Park in 97 or 98, so yeah reasonably old. However, I'm told yes, you can still physically over rev them for a split second in the same mannerRed... I use this gearchange system on my Walky....

I also remember Neil Crompton refering to this on one of the RPM shows, or at one of the races, and it was Skaife they were watching at the time.Red... I use this gearchange system on my Walky....
