Safe engine output for stock crank hub?

titanattack · 05-13-2019, 08:33 PM

what would be a safe tune limit for keeping the stock crank hub not to fail under the stress? I planning to replace my crank hub with the gintani option but
i would like to tune the car since i got bootmod3 and no money to do the crank hub upgrade now. Any suggestions will be greatly appreciated from you guys here
thanks

Nobody knows (except maybe BMW and they ain’t talking). If there was a clear limit there wouldn’t be anymore SCHs would there be?

Do some searching on the subject and you will have more reading about it and numerous theories than you’ll know what to do with.

I will say if you don’t have any money left for the SCH fix what are you going to do if something breaks and BMW voids your warranty?

Yea hard to say. i ran bm3 stage 2 and e30 for almost 3 years. Switched to full e85 and then the crank hub spun literslly 4 days(100) miles later..
