I think that should tell you all you need for tools
Wow OEM repair lists. "Breakaway torque of central bolt > 600 Nm." Thats 442ftlb. And thats not enough to prevent slipping.

How long of a cheater bar is used to create that much torque?

422ftlb torqued? wonder if that's the threshold

I know there are cars with more torque than that w/o spun hubs including mine... regardless I think I'm going to install this

The cars make that in stock form for ZCP... that's not how that works there's friction washers etc that increase that number's clamping force.

For you guys running E85 tunes, are you guys running level 2 or 3 on trans shifting? I have only been running level 2 so its not so violent when shifting and less chance of SCH.

Level 2, manual, only.

Bolt torque needed to be applied to break the bolt free- it is not engine torque created when operating. Engine torque has near zero effect on the timing chain.

So anyone have this installed besides EAS and want to give some feed back on how the car is running? And by running I mean you’ve got some good pulls in, actually put this piece to test.

We just completed dyno tuning this M4 with Pure S2 turbos/methanol, holding up well so far.

That is a lot more work than I thought

At what stage do you just say fk it, drop the motor and build the short block, rather than just doing the crank hub swap

I thought only crank hub fix, charge pipes, and HPFP if e85 are needed for 700whp.

I've met Tom at EAS. Seemed like an upstanding dude running an honest business. It's hard to do well let alone survive in Socal with a bad rep. It's a small enthusiast community esp in this day and age of Google/Facebook properties where there's a ton of oversharing.

As much as I disdain internet users in general, this forum included, there is value in anonymous & open conversation. It's a poor man's way of keeping vendors accountable.

I do want to get some additional "sensible" power out of my 1-yr-into-factory-warranty S55. If/when I do turn up the wick, I'll definitely keep this EAS solution in mind, part & parcel in the pay to play M/911/AMG world.

Thanks, Tom@EAS, for bringing this to market backed by your services + reputation.

Undergoing installation right now....along with Pure Turbos at AutoTalent' 😊 (and it has been a pleasure dealing with them)

It's gonna be hard for anyone to report back after installation unless they then spin the CH. otherwise the assumption is that it works as advertised

I worry about several things, I do not understand them.

1 - Bmw knowing this problem, why bmw have used this engine in the M2C? Will this engine have the same problem?

2 - All the companies that have designed a solution, at some point have written "we would have liked to do it in another way". Do you mean that it is a result with a limitation? Then it will never be a definitive solution, but a solution with the limitations that the engine allows them to work.

They know the solution, but they design something that is not what they would like. They do not give me confidence

Moving from friction discs to a 1-piece hub is the solution, which is what VTT is offering.
