I am starting a 1.6TD build version 2, hoping for more than 40,000 miles :D

It is still working. I will need to get some more pictures soon, but I have been busy.

[Alcaid]

So when will you start to use it properly?

[theman53]

Too much invested time to talk much about it. I have been using it properly as it is still running. I am trying to find the duty cycle of the turbo before doing what I would like to it. As a high performance daily I want to run the boost up to full boost most all the time. If this thing doesn't like it I want to know before I do that.

Cool man, just keep us abreast of duty cycle experiments, and when you have found the sweet spot of the turbo.  Like a said before, even without the turbo, that engine is a nice piece of engineering.  I might eventually be temped/forced you go your way with my turbo selection, due to our setups' similarities, so I'll be watching intently!

[Alcaid]

These turbos comes from small trucks, that means running high boost all the time. You will never be close to that if you even tried. Then you should worry more about the police than if the turbo takes it. This is built for it and is not going to self destruct like badly matched T3 hybrids

[theman53]

That is all relative to me. What is high boost? 33psi, 40psi, 53psi? I am trying to find someone who says I am running this at 40 psi peak but 35psi all day long with 0 issues, at the track, for the last 8 years... or something like that. Or if holset  had a paper stating if you are in the 70% island of the map or better than that, then you can boost it 100% of the time.
I like the turbo but until I have 10,000 miles or more I can't endorse it on the forum. I would hate for someone else to have this kind of money invested and it not be the perfect fit or not last as it is supposed to.

[Alcaid]

These turbochargers are fairly new, at least the version you are running (new this year I believe) so you won't find anyone that has run one for 8 years. The HE221W has stock wastegate pressures of up to 41.7psi, that one is in a generator so that means full boost for hours/days straight!

Here is a paper Holset wrote on their MFS compressor wheels and why they made it, exactly because of high boost applications: http://www.turbo.com.sg/e-news/Microsoft%20Word%20-%20Technical%20Bulletin%20Q2%20_8_.pdf

Believe me, we have really tried destroying these and have had no luck yet, running up to and slightly beyond 43.5psi of boost.

[Alcaid]

We dynoed a 1.6TD with the the same HE221W version as you have (the smaller version) yesterday

204whp @ 45 psi, Some pump issues, starts to taper off fuel too early (5200rpm). and it is fueling too much at low rpms choking the engine somewhat. Still running stock cam. Should be some more whp in there. 1.6 head with AAZ intake valves and some porting. Your head (and mine) requires less boost as they flow better.

I would not recommend running this turbo at 45psi in the long run though even though it pulled all the way to 6000rpm without loosing a single 0.1psi of boost (not choking = more whp in there)

If I had a guess I would say I am right there too for the HP potential. I don't have enough fuel I don't think. What pump did he have that was doing that? Also I am glad he went with the 1.6 head as I think it has a better base shape than the 1.9 heads, but the valves are bigger in the 1.9. How ported or is his head stock?

Thumbs up, nice power! How about torque and dynosheet?

Pump was not behaving correctly (11mm pump BTW), engine drowned in diesel and then all hell and boost broke loose at 4k RPM, resulting in 345Nm (254ft-lbs) at the wheels. Dyno operator forgot to save the best run for whatever reason, but there are plots from at least some 190whp runs where fueling was even drowning high RPM power. Haven't gotten hold of them yet as I had to go before the dyno session was over.

That is gorgeous alcaid! Id love to see that car in action. Is it yours or someone else's? Is there a build thread?

It is a friend of mines car, build thread is in Norwegian

Does not matter, would like to see anyway

curious to know what the pump was doing. I have never seen one drown in diesel. Also, what porting was done to the head?
