New Crank Hub Solution to Market

DuMa M3 · 10-19-2018, 12:17 AM

Sounds promising. I want to see some writeup on the install

guess2098 · 10-19-2018, 12:28 AM

I would go try if they have it in stock

I’m no engineer but can someone explain how this works? When I think of a spline extractor (the thing to use to remove stripped screws), the extractor is conical shaped to wedge into the cylindrically drilled hole and when turned it locks in with the pressure due to the wedge and the splines biting in. How would this wedge into the crank and therefore have the splines “bite” into the crank snout? We aren’t adding material to the hub so it can’t wedge in can it?

Please excuse me if I’m totally off. Just trying to learn.

So if this is half day 8-12 hours depending on experience I assume

what is hourly rate of your shop? about $160 an hour?

My local shop in Arizona is 95$ an hour and they have done many turbo swaps engine builds etc.

I think it's the same thing but female.

Or another way to think of it is the cone is the crank and doesn't have the splines and when placed into the drilled hole (hub) the splines are inside of that. So just transfer the splines to the hubs inner diameter instead of the crank in your minds eye. Pretty trick.

In the other thread someone mentioned 8 hours of labor (I think he called VTT). The video mentions $2000 for labor so they are charging $250/hr labor rate. Isn't this too high? Can anyone recommend any shops in Bay Area or even in SoCal that can do this install with more reasonable pricing?

tom @ eas · 10-19-2018, 03:15 PM

Ordered and installation already scheduled for this item, along with Pure S2 turbos.

///Mobbin · 10-19-2018, 03:28 PM

Good to see another option here and looking forward to more install information.

Extractors are reverse threaded, so when you turn it a certain way (loosen) it bites in and grabs. Same principle.

Is it just better to do a short block at this point?

I believe Tony said the VTT crank hub costs half the labor cost of all these other crank hubs to install.

I believe video mentions that other solutions charge $2K in labor and that the VTT crank hub is about half that in labor. So About $1200 if I understood that correctly to install

Maybe I misunderstood but his words in the video are "Save yourself 700 bucks and 2000 bucks in labor and get one of these instead of a pinned hub. They do the same thing for a lot less.".

I get that. I just assumed that since the extractors are usually wedged it, that pressure from the wedge and combined with the bite the splines is what keeps the grip. I’m assuming the original crank hub without pressure freely turns in the crank. So this new design just removes material to make the spline grooves, I just thought all its doing is just taking away surface area that touches the crank.

I’m not discounting their effort just trying to get an understanding from and engineering perspective (though not an engineer)

ssgm1x · 10-20-2018, 09:43 AM

Update, Confirmed... about $1200 to install.
