Camera?! Tish-tosh, you can get the information you seek with a Sharpie Marker!
Draw a Mercedes logo on each pulley face the next time you pull the belt cover. Erasure tells the tale.

This is great, Dawgs! Some Empiric observations:

The 90/90 has a nominal height of 3.18". Multiply by 2 and add the 10" rim and you get 16.36. Times pi and you're right at 51" inches circumference, give or take. The 3.50s calculate to 53" circumference.

I actually measured one - can't recall which - with a drop of paint and got 52", so maybe 49" is close for 3.00s but too pessimistic for the bigger skins?

I did that. Only it wasn't in the cover, i had the rear half of the af16 cover off.

How did it work out for you? Any pictures of how you mounted it to keep it rigid? I still need to device a way to do this for my af05 that has a one piece cover.

I remember seeing somewhere on youtube that some guys actually put a high speed camera in the jug of a 4 stroke engine. Then they ran it and you could see the different strokes and the valves move, combustion, etc. It was really cool. Ovbiously it wouldnt be that extreme but same concept

Yes, they started that in the late teens or early twenties, I don't remember the exact year. It is one of the reasons they started gas standards.

That will tell me the max travel but I am interested in certain points at load and coasting. Then with different springs to calculate ratio changes caused by the face.

Since it serves no structural purpose, the 1-piece 05 cover can be bisected with a hacksaw. Light on the belt will be better and the clutch'll run cooler too.
I had a used Sym cover that had been so modfied.

FYI -

In the interest of reducing the amount of bad data, the original posts have been edited with replacement table and graph. with notes covering the change.

Where did the problem start? I used 80/90-100 tire dia (398mm) rather than 90/90 (416mm/16.38").
Tire chart used is covered in this thread

Neglecting belt slippage, given 2 tachs (front/rear pulley), this could be manually calculated. Anyone seen commercial products which gather the data, calculate and display the result? Adding the rear sensor to an existing tach/speedo computer would make a useful gauge.

An excellent idea Mouse. I even have the tachs for that from doing industrial belt drive work in the past (insert headslap here for not remembering this). Thanks.

Guys,what's the ratio on af05e gears, and will they swap in a 16e? Also what speeds can be reached with them

11.1:1

I have them on my chart as 11.2

they should swap in with no problems

you will need engine speeds of 10k to see 50mph.

[StrokedSr]

Well i don't have a tach.. So guess I'll never kno.. I wonder if the pg cAn rev that high

There are also the less common 10.2:1 gears and then the aftermarket 7.83:1 gears, assuming you are talking about the variated af05e. I don't remember the ratio of all the spree and E gears.

Combined gear and variator ratios are on the wiki at this link

link to video below. I mounted a piece of metal to the trans oil plug and the camera mounted to the piece of metal. I'd have to find the metal if you still want a pic. Works great for tuning.

sweet vid

[StrokedSr]

so t- jamz.. what you think.. can i hit 50 0r more with the setup i have meaning you think ill rev out to 10k?
