Ball Bearing Powermax?

Let us know what you find out, saves me from calling, I saw it ball bearing, and when you go to it's site it says jounal bearing, but the ad in the background states ball bearing???? I think it's worth the extra money, you open the hood and if you look in just at right angle you might see some of the purple paint.........

I have to admit that I am a sucker for PURDY colors

What's gonna be the biggest diff between a non ball bearing and a ball beating turbo

[windrunner408]

spool up and response is all. Maybe a little bit more air on the top end but more than likely not enough to notice.

Ball bearing turbos spool easier than journal bearing ones do so it takes less exhaust gas to get the turbine to move as opposed to a journal bearing turbo.

I saw that special edition pmax he was talkin about, so it's not worth it to take a look at if it's ball bearing? Also what's the diff between a vgt and non vgt? Don't in the non vgt the vanes stay in a certain spot all tw time as opposed to the vgt which open and close? Am I correct on that may be wrong

If your horsepower goals are 500hp and less (i.e. 155cc injectors or stock), I think (that while a little expensive) it would be a GREAT turbo as it would definitely spool quickly (I would think).

VGT is Variable Geometry Turbine. Fancy way of saying it uses vanes to control the flow of exhaust gases over the turbine wheel. As the vanes move the shape and angles (geometry) changes causing the gases to flow optimally over the turbine wheel.

Non-VGT (or Fixed Geometry) means NO vanes and the exhaust gases enter and hit the turbine wheel at a fixed angle ALL the time. This initial inertia of the turbine wheel and compressor wheel typically slow the response of the turbo down to being able to control or adjust anything on the turbo to get it to respond as quickly as a VGT turbo. This isn't to say that the turbo doesnt spool at all as they most certainly do but they are sometimes not as responsive as the VGT turbos.

Advances in tuning and fabricating have come along way in helping the 6.0 spool non-VGT turbos but IMO they are always going to be slower to spool than a properly tuned VGT turbo. JMO and hope it helps.

So unless you are running the kinda horsepower that pretty much your running there is no reason to buy a non vgt when you can get better response from a good tuned vgt turbo?

The 6.0 Pmax turbos from Garret are not BB turbos. That is the generic description that they have been using in their advertising.

IMO yes

I called MKM and talked to their tech he told me yes it is ball bearing, made by garrett for their special edition. Guess what I have coming to me, why can you say mad turbo werks stage 1, 2, 3, and 5 ball bearing? We'll see, depending on how it performs.
