Turbo wheel measuments

[zukgod1]

Hello all,

I currently have a NA car so I have nothing to use for compairison.

Wondering wht the major/ minor measurements are on a stock compressor wheel.

Same for the Exhaust wheel.

Any have a link to that info or just know it?

Yes I did a search, it was a quick one but a search none the less.


Thanks

dan

That's what I needed, Thanks.

Basically I was wanting to compair to 2 turbos I have sitting in my shed.
I have no idea what one is but it seems small, I'll be taking it appart soon to measure the wheels.
The second is a HY-35 that I got for my Toyota Diesel project that's already sold.

I was really wanting to just run the HY on the 1.6 but I doubt I could spin it untill like 5K rpm. Just to big. If I was really ambitous I could use it in a compound series but I just dont think I can get that done.

Here are the measurements from the links and the measurements onthe HY I already had.

Stocker Turbo
Exhaust Turbine
inducer 49.5 exducer 59mm

Compressor
inducer 37.5 exducer 60.5mm

Holset HY-35

Exhaust Turbine
inducer 58 exducer 65mm

Compressor
inducer 54 exducer 78mm

Funny thing is that I've not only had an hy35 on my 1.9 but in a compound setup with the stocker turbo.The hy spooled too little and too late.Another guy on this forum (Hilfolk'r) spl?? used the hy35 as a single with his mechanically controlled TDI and had very similar issues as me we could both only manage 20-30 psi with either setup.

There is also a smaller turbo that came on some of the US 1.6 diesels it was the k14.The 1.9 TD in canada used the k03,T2 and k14.

originaly I was going to install the HY on a 2.2ltr toy diesel but sold the truck.
I was concerned that the 1.6 would have a heck of a time spinning it.
This is now confirmed by your post.
Let me ask though, even with ony 20-30 psi wasnt there enough/more air flow than with a large single?
I would think even if the HY wasnt spinning up where it could be that it would be moving more air than the stocker could at the same RPM.

Oh ya, I've spent some time reading that one for sure.

The 20-30 psi comes too late in the rpm (22 psi @4500rpm approx) well past where we need it for the diesels torque at much lower rpm.The only way to get it spooling to 22psi was burning over double the stock fueling.The stocker T3 turbo works well upto 23-24 psi and spools 10 times better.

That's what I was afraid of.
I'll just find a good stocker for my use and drive it till it breaks.

But what we are not comparing apples to apples, the volume of air the hy35 moves at 22psi, is far greater then the volume of air the T3 moves at 24 or even 30psi. Hence the reason that it takes double or more the fueling. The Hy35 as a single turbo moves enough air (intercooled) to support 280-310whp of fuel. The T3 maybe 130-140whp (intercooled).  :wink:

This is a good point.

I guess the question would be then would the HY in a compound config move enough air with say a Giles steroid pump and some larger injectors to keep the EGT's livable?

Say set the waste gate on the small primary to approx 15-20 psi and hope the HY is spinning by then so when the small turbo is getting close to the end of it's MAP the waste gate opens and the HY takes over.

See I don't plan on racing this car at all, it's a commuter. I want it to be a fun commuter to the point that if a ricer decides to overtake me I can wind it up and watch their jaw drop for fun.

Well you would, have to ask Andy about that as he has the only running setup like that around and at this point it is just a challange to keep the head gasket from leaking. Maybe after o-rings we will see just that.

I think for any sorta serious power we are going to have to be willing / capable to run into the 6500rpm+ range becuase then a turbo like the hy-35 becomes a viable turbo, giving a full 2500rpm's of usable boost.
