At what point do I need to upgrade crankhub?

Title says it all. At what point (hp) should I upgrade the crank hub?

I will be stage 2 by the end of March at the least. Parts are on backorder.

Is the crank hub a concern with just CAIs? They will be the first mod to go on as they will be here this month - mid-next month.

And my main question: Is a crank bold capture an effective alternative?

Everyone's opinion differs.

I went with the capture on stage 2, and changed with crankhub when I got a custom E tune. From all the info I gathered, that was the right thing to do.

I wouldn't worry with CAI (you may actually be losing power at times).

We upgraded to the Insane crank hub 2 pin when we added e85 which is 600whp +or -.

But, honestly i've seen them spin on stock car and stage 1 only tuned cars so I don't really think there is a Hp number perse.

First mod should be crankhub. Your putting the fate of your engine on friction plates and a single bolt

Most customers upgrade it after the basic mods, before upgrading their turbos.

does it spin...it sure does. your paying well over half its repair for something that rarely happens. if it spins, turn your engine off and tow it to an indy who will rebuild your engine. you only blow ur engine if you keep driving.

theres a lot of people who are in cahoots with vendors and shops that get it done and post here

I was in agreement with your post until the last part.

Are you saying vendors are paying customers to post that they replaced their crank hub when they actually did not?

If you are going to make such an accusation, please be specific and name the vendors

That's a far reach.

Think about it like insurance. How often do you get in an accident? Do you have insurance?

There is an exception to every rule, but generally speaking, crank hub issues appear to mostly occur based on a combination of power and shifting style, and primarily downshifting style.

My understanding is that it really has nothing to do with power output within a gear, but about how violently you downshift gears while going full WOT.

So, ultimately, it’s a subjective decision based on your risk tolerance but also based on your driving habits.

If you have a DCT and you think you might find yourself in a situation where you want to be downshifting a gear or two and still going full WOT, your driving habits may require getting the CH done.

If you have a MT and you don’t like ripping through downshifts while full WOT, then I would forget about.

I personally rarely ever find myself in such a high adrenaline situation where I’m downshifting and full WOT. I’ll usually just complete the shift and then get back on it because I’m not in a time trial.


Just my 2 cents.

Insurance doesn’t cost you half the cost of your car every year, so I don’t feel like the analogy holds. Crank hub issues don’t seem to be nearly as common as some would have you believe.

And a car accident doesn't cost you the total of your car every time you get in an accident? I don't get your argument. Changing the crank hub cost me 3k total. Not sure how much it costs to replace a blown motors, but I know it's not 6k. Do you blow your motor every time you spin the crankhub? No. Just like your car is not totaled every time you get in an accident.

Like I said earlier everyone has their own opinion on this subject. I chose to get it done because I have close to 600whp. I also respect if you chose not to.

nope they most definitely did replace their crank hubs, and probably for good use as they have race cars... but likely they get heavy discounts for their crankhubs installed for a shout out...look I am not saying there is anything wrong with that. Just describing the reality of situation.

does you car get totaled after a crankhub spin? it seems your super race car so its the least you can do.

most people here just have minor tunes and stock maps...ergo your paying more than half the repair cost maybe even 75% of a repair cost for something that rarely happens.

Above the GTS tune a crank bolt capture plate is a good idea. It would keep a crank bolt from loosening.

My gauge for a hub fix is above 600TQ, because we’ve seen one CBC+StockHub slip around 700TQ. The IP style 4-pin one-piece is the toughest since it has no friction discs.

When you do a hub fix please put a CBC on top at the same time, it’s only a $125 part. There’s one report of a hub bolt backing out after a hub fix was installed.

You won't need to change it unless you are making the sort of power/torque that requires a turbo upgrade. This is my conclusion after hours of prowling through forums of owners, from those that spun in stock and those running 500-550whp without the fix. It's all about your risk tolerance. Are you feeling lucky?

I don't doubt this is the case, but you still should name the shops that do it.

We sold
~ 200 insane
~ 120 SSR
~ 250 Vargas

We never gave customers any additional discount to post about the crank hub online. All the feedback posted from our customers on the crank hubs is 100% genuine.

look the crank hub is a self fulfilling prophecy on this fourm like many mods. just like most expensive mods, and all things in life, "influencers" get it for free and gas it up. doesn't matter who does it or not. its not the ethics of it...its the loopsided information. its annoying when all someone cares about is the crankhub on this platform, its not rod bearings on the s85/65 which are ticking time bombs.

anyways, make your own decisions
