Is the turbocharger on the new EVO VIII a ball-bearing turbocharger, or is it a sleeve bearing? Anybody know?

 

Isn't the turbo 16G?
Same turbo used on the Neon SRT4??
(sorry.. this is sort of a diff question)

 

I think you are correct about it being a 16g. I believe there are several different versions of the 16g though. Some with titanium some with Inconel. I really want to know if we have ball bearing turbos or not (on the new EVO VIII)? Are some ball bearing and some sleeve type? Somebody out there must know...

 

I belive the turbo is a 16g TD 05H, which I think is Ball Bearing.

But i could be wrong.

a TD05 16G tells you nothing more than its official size and compressor side......ball bearing 16G's are actually not a very common occurance at all.

That being said, it is not a ball bearing unit, but does feature an Inconel compressor wheel (about as good as it gets)

Twin-Scroll TurboCharger

Boost Pressure @ 3500 rpm: 19.00psi
Boost Pressure @ 6500 rpm: 16.24psi

 

The turbo in the EVO 8 is a Big 16G . It is not a ball bearing turbo . They also are not the titanium wheel either. But there are companies out there that are making upgrades. None in the US...............yet . The Big 16G is capable of low 12's - high 11's, depending on your steup. We will see just how fast the stock turbo will go at the annual DSM shoout-out on July 20th at Norwalk Racetrack-Ohio.

 

I think we will find out sooner than the shootout. Buschur is trying to get his car to the track if the weather allows. He feels the car should drop into the 11's with the stock turbo. I'll be at the shootout; I have a grudge match with a friends VR4 Gallant. Both have 4 doors.

This may seem like a dumb-*** question but

what is so good about a ball-bearing turbo?

 

My personal preference would be a ceramic turbo with ceramic ball-bearings.

 

So there may be an available upgrade to a 16g ball bearing turbo soon? I am not really trying to get into the 11's, I just want to reduce the turbo lag. Our EVO's have extremely poor throttle response. Below 3000RPM's they are absolute turds. Maybe the titanium impeller and the ball bearing center section would help spool the turbo faster?

 

They would but in the mean time you can add an emanage (w/ ignition control) or Vishu's stage zero. The problem you describe can be fixed by adjusting timing and mixture, add a exhaust and it's a whole different animal

 

They tend to spool faster and can handle much higher RPM's.

 

All standard turbos have a inconel turbine, the titanium turbine would be the unit of choice for spool up. The compressor wheel is aluminum.

Evo turbo is pretty unique with the twin scroll turbine housing and spinning backwards. There are ball bearing upgrades available from a least one UK source.

I'll be there.
