Would you run this? 🏁🏁🏁 How many discs your differential has?🎯 Grooved discs or Drilled?📈 How much preload? And why? Do want it as open as possible without compromising performance or the redneck way 'ON/OFF' switch?

If you like speed holes, read this.

The two photos show a CAD replica of the time attack wheel hubs machined by .

I don't know if the holes have a function. At first, it simply looks like speed holes 'to add lightweight'.

During the first semester of any good University like you will learn that drilling holes is rarely the optimal way to reduce the mass of a mechanical part.

It took me 30min to make the hub and do FEA on it. From that baseline it took me another 10min to fill the 10 speed holes and make a very small change to the back of the fl**ge itself. Back to the FEA with the same load case, the improved hub is now:
-Lighter
-Stiffer
-Stronger
-Less compliance
-Reduced stress
-Improved load path
-Improved fatigue life
-Take less time to machine
-The CNC code is shorter
-etc

I will wait for their explanations if there are any. My solution with more details will be on the VIP section of my Patreon if you're interested to learn how to improve motorsport parts like this.

You can also follow my new Instagram account the main objective of this is to improve the standards regarding engineering design of race cars. Rule #1: avoid single sheer, REIB and speed holes👌🏁 I promise that what is common sense to me will soon become second nature to you!

BavarianDiffs

We build custom Bmw limited slip differentials for endurance racing teams in the USA and Canada. If you are racing in Australia, Finland, UK or Germany, you might also be competing on the track against racers that use BavarianDiffs services and products. We build medium case and large case differentials: e24 e28 e30 e32 e34 e36 e39 e46 e60 e82 e90 e92. Serious racers come back to us for more diffs with different final drive ratios to optimize their performance on specific racetracks.

Simulation & Consulting Services

We offer vehicle simulation for acceleration, our on-track experiences and iterative mathematical model will help you to choose the optimal final drive ratio. Contrary to popular belief, a shorter final drive ratio won’t always provide optimal acceleration between corners. Ever missed the podium? You can have the fastest lap time but to win you must be able to overtake, think about that sections you were really close to pass a competitor! We can optimize your chance to overtake.
