Hi Bryan. I'm in Boca and would like to join the whatsapp group and know where you got the hub installed. They have a new BMW dealership in Delray but I know the guys in Pompano are really good. Leaning toward the Max hub based on the thread. I've got a 2016 with stage one and don't ever track it... except on 95 Should I even get this done?! I'm sure it's gonna be expensive. $4k out the door? Thanks for your insight... Ivan

Just curious, are all your warranties over that your switching the crank hubs? I'm running stock set up and don't plan on getting a job till the warranty has expired or plan on tracking the car either. There I no guarantee if these aftermarket hubs are any better, any test results?

If anyone is wondering, I messaged Insane performance on Ebay asking them what material the hub and pins are made from. This is their reply.
"The hub is made from hardened steel, 12xH3A mark. The pin is from bearing steel GCr15."

What I dont get is why Insane does not taper their gears on later hubs, like OEM, Gintani or MaxPSI ones. This can be big issue when gears catch chain sideplate. Non-tapering is not accepted solution for such high speed, high vibration usage.

Non-tapered sprocket teeth is simply bad design for that application, end of story. Keep in mind that this is high-vibration, high-speed, high acceleration/deceleration environment for chain and sprocket teeth need to contribute to the chain centering action. Otherwise there is a risk for them to catch side plate.
I did not invent how the sprocket teeth should be designed, this is basic engineering requirement as you can read from the IWIS material. Here is good analysis of different alternative hubs: https://f80.bimmerpost.com/forums/sh...7&postcount=38 In short, shop wisely. |

i bought one. Took one day to get here from Lithuania.
I looked closely at the sprocket and it looks like its maybe shot peened. There is a bevel and a chamfered edge on the sprocket as well. It might not be as pronounced as the stock but it's there. |

looking at the vtt v2 hub where it is removing a small amount of material as it enters the crank,does it leave a gap for the debris to sit? if not when the bolt is tightened you are simply compacting the debris and not acheiving the full insertion.

Check out my IG @that_tech_mario... I've installed about 15 insane performance crankhubs and they all been running strong for months. Also if you follow my IG I get discounts on them.

Gintani's crank hub "pin" is a machined "lobe" which is part of the 1pc hub. Only one side of the crank snout is drilled and then filed down to fit the "lobe".

I think I read somewhere that the oil sprocket doesn’t do anything regarding spinning the hub, so to lower production costs, Max psi probably didn’t think It was necessary

Production costs in Lithuania must be real cheap then to offer this for around $950 on eBay. Anybody care to share what the lowest offer they are willing to accept for this part? lol
