How Turbos are made
 

Turbonetics <3

Good video.

I need to see one that shows how they make McDonald's cheeseburgers.:icon17:

Cool Video

I love those how it's made episodes.
15 minutes to make something they charge thousands for, haha.
Seriously.

You forget the hundreds of hours of engineering to design it.....and testing the design.

Manufacturing materials and tolerances also come into play. Holding things in the microns ain't cheap. But yes, there's always a sizeable markup on stuff like this to pay the research, overhead, oh and yeah, to make lotsa $$! Ha

Nice!! Now I kinda want a TT setup...

eh they skipped a lot. it takes several hours to make a turbo and thats with many people working at once, but they are also making more than one at a time. It would be interesting to see the billed hours and material cost for a turbo, you are buying a machined inconel shaft that is spin friction welded to a cast/forged inconel turbine wheel, supported by bearings that cost around $20-60 dollars a piece if it's a BB turbo, and if it has a carbon seal you pay for that, and then there is the bimetal thrust washer, the housing has to be cast and machined, and you have to keep the lights on in the plant, pay for r&d, kickbacks for the share holders, benefits, comp and buisness insurance, legal for all the patent work, accounting so you can spend money paying for all these things, and taxes on any money you do make. I mean they aren't ipad cases (which take a whole 6 or seven seconds, are made from 10cents worth of plastic, by a man who make 2 dollars a day if hes lucky, and retail for up to 50bucks, hell the most expensive thing about one of those is shipping costs)

Also turbos aren't manufactured to micron tolerances only the bearing in them are(and only if BB) Rember the old lexus add about how their motors are made to tolerances tighter than the thickness of a human hair (.003 which doesn't say good things about bearing clearances :shakes head: )

Almost the same as in the video above only they pour liquid beef and "other animal byproducts" into the molds instead of molten metal. Actually, a couple of day old Big Mac patties make great impellers.
