what's the difference between billet wheel 6262 and the cast or normal 6262/.82 both BB

 

+1

 

I'm guessing slightly better spool do to a lighter wheel. As well as a better flowing wheel do to a better

 

Faster spool with less heat.

that mean the billet wheel is better than the normal one ,,,, so I would go with 6262/.82 BB billet wheel ,

thanx for all of you

 

Yes def if you can afford it or save for it billet wheel technology is the way to go

 

folks. there is no cast wheel 6262.

Well, then I'm going to make one.

 

yes the billet is better lighter and faster spooling so ya its better!

 

billet wheels are not always lighter than cast. Billet wheels were originally created for diesel and racing applications that required beyond 50 psi of boost. Normal cast compressor wheels would actually bend if they were not thick enough and large enough of a wheel and subjected to constant 50+psi. So billet wheels were made to handle the higher boost without actually bending. IN 90% turbos in street and import race cars, a billet wheel is not needed because those types of boost levels are rarely achieved. Many companies have done an excellent job of marketing billet wheels for what we would consider normal turbo applications that would not require them. Not taking away from the turbochargers that actually implement tham at all, many of them are newer, more efficient designs, but one would might be interested to see a billet wheel and a cast wheel of the same size and a/r on a scale. I think many would be suprised , especially if the cast wheel has been back-cut

 

my 850R came with a billet wheel !! i think garret has a link on there webpage that compares billet vs non billet wheels i just cant find it right now

 

Get the billet.

 

norcal might be right about a 6262 coming in cast because ive still yet to seen a cast wheel in 6262

 

yah i have ordered the 6262/.82 BB billet wheel .... thanx

 

Correct. In the performance segment the billet wheels are advertised as such when they also are of the newest designs. BW and Holset have designed some of the more advanced compressors and manufactured cast wheels with them, but they are still edged out by the billet wheels that can implement a smaller hub. The smaller hub means longer blades, which is equal to more inlet area/higher mass flow capability.


Correct, there is a 61mm cast but no 62mm cast.
