Should I worry about crankhub?

travismelo3 · 12-23-2023, 02:16 PM

Hi all, I have a stock crankhub S55 and I have intakes, downpipes, and a midpipe but NO tune because of warranty so I’m assuming I’m around 460 wheel. Do these modifications increase the chance of spinning the crank hub by any significant amount? I’m increasing the power by a bit but not tuning it, so I think I’m fine but just want y’all’s input. Thanks!

There was a survey taken on this forum. If you are close to stock hp, there was little to worry about. Check it out for further peace of mind.

No. I added a GTS tune and haven’t thought about the crankhub once while driving my car.

Totally fine with stage one or below. Personally I wouldn’t think about it with stage 2 either.

E30 Stage 2 over 7 months with stock hub. No issues.

That was me on MHD stage2+ running e50 for sometime as well. Had no issues for close to a year though I always hisitated to go full send. Ended up getting mine pinned and have peace of mind of not worrying.

On a side note, with the E content def check your injectors, mine def weren’t flowing as strong after a year swapped to S63 injectors when I got custom but I digress.

No unless upgrading turbos and remapping

No. It pretty much depends on you and your right foot. Don’t wild out with crazy kick-downs.

I did crank bolt capture just for a little more peace of mind.
I'm on custom stage 2 on full E85. I drive 99% of the time with the paddles to avoid any kickdown issues occurring.
