According the online instruction manual, page 36, I think there's something wrong with first table:

Default Shock diaphrams?

Hi. Just been reading Mr Moss's worksop set up. It says diaphram centres cut out and removed. How,what and why is what I was wondering? Thanks for all the advise. It is invaluable with such a new car. Cant wait to run mine.

oliv : give us a clue what you think is wrong i'm clearly missing something

the shocks have bladders fitted as standard like most tourers and 1/8th rallycross, cut means the top of the bladder has been removed making the shock more tike the associated 1/10th buggy style, its just another tuning option.

Think he might be thinking that it means the minimum teeth is 99 yet it goes down to 80 on the chart.

But if you look oliv, the total minimum 'combination' of spur+pinion is 99 total, 83 spur + 16 pinion = 99total.
And max combination is 80 spur + 28 pinion = 108 total.

I know it has 80 spur and 16 pinion on the chart, but I'm assuming that this combination can't be used.

So therefor it all looks correct to me.

Pretty much spot on. While i have been testing the car all year Ive have tried shocks with full diaphrams and the cut diaphrams. All i do is cut the complete centre out so you are left with the outer ring. You need this so the oil doesnt leak out of the bleed hole at the side. Personally, ive found the shocks with cut diaprams feel better as opposed to the others, they feel more fluid and give less inital pack in my opinion.

Assuming following data:
Diff pulley: 36T
Pulley just before diff: 20T

For the first cell (pinion 16T, spur gear 83T and 34/22 combination) it would be:
(83/16)*(34/22)*(36/20) = 14.43 instead of 14.37

The two others tables are correct

looks like somebody incorrectly calculated the internal ratio to be 2.77.

if i'm honest i hadn't looked that deeply into it as all the numbers appear sensible at first glance.

3 Questions.....

What pinion size should i be looking at for a kit set-up 33/23/83 using an LRP Sphere TC Speedo, and LRP Vector X11 5.5 with a sintered rotor?

What is the rule of thumb when you change a bonded rotor for a sintered rotor with regard to pinion size?

Is Worksop clased as high or low traction?

Cheers in advance.

Ryan

Kecky i've heard they are bringing out a maintenance pack for £90 with a load of stuff in it like WISHBONES etc. If you buy the same parts on there own it would cost you more

Due to a change in motor, can anyone help me with the gearing.

I will now be running a Novak Velocity 7.5L Motor, and Trakpower 3600 Lipo cells, with the kit set-up 33/23 & 83 Spur.

The instructions with the motor state you should gear 2 teeth lower than you would use for a 12 or 13 turn brushed motor.

Any help would be much appreciated.

Ryan

I'm guessing here and going from other setups but i'd start on a 21t and go from there ryan. Better to gear low and be safe mate.

Cheers Stegger

The motor info sheet says 2 teeth lower than a 12t or 13t brushed motor and 1 tooth lower than the 7.5R motor.

I'll start off with a 21 and take it from there
