Hi John,
Sorry for the late reply,
you speak of a turbine wheel with a larger exducer.
What about the inlet? It is also too small (20mm). The inlet area must be larger.
what dimensions do you prefer for the turbine wheel (please in mm-mm²), what are the calculations?
Thanks, Ralph

Hi Ralph
Ideally I'd need a 140 mm diameter turb wheel with a 25 mm inducer tip height and a 125 mm exducer , but they aren't made .
The GT6041 turb wheel with a 130 mm inducer and 25 mm tip height and a 119mm exducer is a reasonable size but theres no quill on that shaft as the boreless GT6041 comp screws on, and its a very expensive wheel to purchase .
The G Trim TV94 turb wheel( 129/112mm) is as big as we can get with a quill that can mount our billet comp wheels , and its purchase is stretching my budget rather severely :-(
Cheers
John

John, can you share the details on the G trim. Part number, price, delivery etc.
Thanks, Ron

dieselguy86, thanks. Good informatioin. It looks like the Holset G trim is a little smaller than the Garrett G trim John is sourceing.
Thanks again, Ron

Has anyone information for the Mitsubishi TF/TD15 turbine wheels? These seem to be used in various big machines, CAT, Yanmar etc. It might be just equivalent to HX82 and GT60 -series turbos based on comp sizing, but I remember even the TD13 turbine was already around 110mm exducer? I only managed to find some price tags for OEM parts which was several thousand USD.... but probably someone makes an aftermarket wheel too. Edit: I found the TF15 model when I was browsing the big comp wheels on KTS catalogue as they had up to 139,7mm inducer option available  |

Just a quick note on the Holset vs Garrett wheel. The Garrett has 11 blades to the Holset 13. It is also clipped slightly, so probably will flow slightly more than the Holset. I received my Holset bearing parts. The thrust bearing is much better. A modern 360 degree design with pressurized oil delivered to both sides. The shaft is slightly smaller where the thrust washers go, and they will not work as is on the Garrett wheel. The bores will need to be reamed or the shaft turned down.

Hi Monty
Do you think perhaps a change over to all Holset stuff including the wheel/shaft might be in order ??
The 11 bladed Garrett wheel probably is less efficient than the 13 blades of the Holset especially for your application .
I'd be only too happy to purchase your Garrett wheel from you as I'm still trying to get through to the suppliers in the US to purchase one .
Cheers
John

John, what is your best guess of the G trim corrected flow versus pressure ratio map? A corrected flow of 150 pounds per minute at 3/1 choked conditions?
Thanks, Ron

Possibly. I am looking at some things right now that may lead me that way. The Garrett wheel has much larger bearings. Something which could be good or bad....not really sure. Though my guess is the newer Holset uses later/improved technology. I'm currently thinking of machining down the quill back to the aft bearing so that is the only bearing in the hot section, with the rest in front of the compressor. Also possibly changing to an overhung reverse flow combustion can.
Do you know what the length measurements on the shaft of the Holset are?
Monty

Hi Monty
That wheel is a tad expensive :-(
I'll keep trying to get in touch with the suppliers of the Garrett wheel .
Andy M will be able to measure up his Holset wheel for you , I don't have any numbers for it other than the wheel dimensions.
On a side note , Columbus Diesel who do a lot of the Tractor Pulling turbos uses Holset stuff as well as some "specials"
Cheers
John
