Updated the subject per your earlier suggestion.

It won't make certain members, who are commenting on this very thread submit their vote, but maybe it'll help others understand what this poll is about.

nars3000 If you had to take an educated guess, based on the data, and your insights...what do you believe the odds are of any F8x contracting a SCH during a lifetime? 1:10? 1:100? 1:1,000??

...My guess, based on what I've seen/read/interpret is that there's maybe a 1 in 50 (very rough guesstimate) for a F8x to develop a SCH.

There's not enough data to make an educated guess on this at the moment, so my uneducated guesses are as follows:

1:10000 for stock cars
1:5000 for 450-500whp
1:2500 for 500-550whp
1:1250 for 550+ whp

Thanks NARS. If it's anywhere in between what you and I respectively think- then I have no fear of light tuning, and no desire to do a crank hub "solution".

I'm a big fan of math.

IF

-SCH is 1:100
-SCH repair cost range is $3k-$25k [avg ~$10k?]

THEN the avg SCH repair cost per M owner is about $100 ($10k x 1% = $100)...

Like I said, I'm happy to take that risk over spending $3k on a solution.

***this is just my opinion based on the speculative numbers. Also, I only plan to do a moderate BM3 Tune on 93oct. IF I was going much heavier mods (I.e. new snails, e85, etc.) then that would probably sway me more into thinking about a solution. Again, just my opinions here...

Why would a SCH repair be $3k (a ridiculous number with no basis) and the average $10k.

That sounds like wild speculation to make your case.

Furthermore, a time line has not been reasearched to determine how long after manufacture the SCH occur - an event that will increase over time with more miles on the cars.

I say that with 110% confidence because if all F8x were immediately parked, the total number of SCH immediately quit increasing. As more miles are put on, the SCH failures will increase.

I've read of several cases where a SCH (partially?) cost $3k-$5k iirc.

Anyways, I read your comments in a diff SCH thread. And I get it. You seem extremely risk intolerant. Take something with a potential cost of $30k, and less than 1% chance of happening, and you'll happily throw $4k into it, tear down an otherwise good engine, and hope that the "fix" works— Not me.

Again, you have no data that less than 1% is the final number.

Even if one cut the current poll in half (or even by 75%), itís 18 out of 158 votes.

1% now might be correct now. But as stated, this number will grow over time.

Speaking of "wild speculation"....

FFS, why does every single SCH thread have to end up with people arguing math over unscientific numbers?

I say that with 110% confidence because if all F8x were immediately parked, the total number of SCH immediately quit increasing. As more miles are put on, the SCH failures will increase.

I agree that you're having difficulty with 3rd grade math.

Well...this thread is based on a poll [numbers], and I asked the member who created it a question based on the poll [numbers], and his experience/anecdote.

I then formed my own opinion based on math and logic to form a basis for my personal decision making..

From there, an argument was created by someone who is challenging the numbers (and logic?)...probably the type of person that would sooner stick his hand in a blender than admit that there are alternate ways of looking at the world than his own.

I agree that you're having difficulty with 3rd grade math.
The sad state of the Education System in your state.

You probably also believe that all cars that finish the Indianapolis 500 run 500 miles and the same number of laps as you have a problem understanding what happens when all cars are shut down after the checkered flag....and what that does to the math.

Just ignore him bro. All of his posts are harsh and argumentative. You will never win by responding.

LOL, I realized after clicking [submit poll] that I should've expanded Comp Package to CP/CS/GTS... unfortunately, getting this change implemented will be a major ask from the mods, as it took me quite a long time to build the poll options.

On a sad note, we may have lost another 2015 6MT M4 (560+ whp) to an SCH today... Our brethren was going for a 60-130 mph run when he hit a major bump on the highway. The car briefly went airborne, and possibly over revved the engine with zero load, then it may have given the engine a sudden shock as the rear tires regained traction when it landed...

I donít believe the motor is shot either itís impossible that it is. I was actually already decelerating when this happened. Iím going to take a 2day vacation and hopefully have a solution of this madness when I get back. The road to 6ís are shattered for now. But I have hope. I was .26 away to hitting 6ís and that was with lifting the pedal too at The end coz I saw the lump on the road and kinda knew the rear would lift thatís why I let off but this happened. Should have I kept pressing the gas? I have no idea.. my instinct was not to swerve and just let off and glide through. Bad times indeed. Car is still under warranty got 38k on the dash. Thinking of the next move..
damnit man, remove tune and take it in under warranty.... how much hp and for how long,,, miles wise?? e-85?

voted in wrong spot by accident. voted in "2018+ | 6MT | Modified 500-550 whp | SCH Failure" when I should've voted for the 2018 comp pack equivalent of that vote. Incase anyones wondering car was more or less fbo on 93 stage 2 with about 8k miles on tune. Was driving on the hwy going at it with another m4 in my area, no misshifts overrevs or anything of the sort, then when I get off the hwy I just get the drivetrain malfunction. Was a lightly spun hub, no limp mode but timing was dead. Took off all the mods for stock parts, tuner cleared my car and into the dealer it went. New hub under warranty; car was gone for maybe 3 days.

edit: car had about 15.1k miles when it happened too.
