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

More boost = higher AFR = lower egt

[Gizmoman]

More boost = higher AFR = lower egt

Definitely a huge orange to a small apple here (the van weighs in excess of 5K fully loaded) but It's all I can do to get my HE200 to 20 psi and the EGT's come up right along with it.

[Alcaid]

Will it boost more if you let it?

[theman53]

Yes, it will peg the gauge at 35psi quite easily now. Never had one do that. Then when the wastegate starts to open it regulates it right around 30. I have a video I will post eventually so you can see all my gauges working. Barely any EGT now.

[Gizmoman]

Wow - sounds like success!

[Alcaid]

See, your Vanagon wants more boost

The HE221W version that theman53 have we have run up to 45psi, not recommended in the long run but it did survive it is very close to the HE200WG, same turbine wheel slight difference in compressor trim and ported shroud on the HE221W.  Both turbos 5cm^2 turbine housings but different downpipe flange

This is a link of how it builds boost.

wow wow wow, what an improvement from when i rode in it!  i feel robbed haha, i want to ride in it now that this has been fixed.

[theman53]

Yeah, I cannot get it to smoke now. I think before it was getting enough boost to push the lda spring down but bleeding off enough to not boost. It is a very different picture now. It ran good before, don't get me wrong, but now it is different in a better way. Come by I will let you drive it

Updates:
I have added a stereo and some old school audio equipment. I will be making custom door parts for the speakers I want to fit in them. Sounds pretty good right now.


I have a continual battery drain and I think it is from the amps. I didn't have an issue all last winter with the battery dying and now it will die in less than a week. I am adding a compositor and hope that will stop the bleeding, it did in other setups.



I changed out the water and now have antifreeze. I should be set for the winter.


I found now that I fixed the boost issue if I rev it in neutral I can make a little over 10 psi. No load, just free rev, thought that was cool as it would make nothing before like that.

[CrazyAndy]

Dude I don't know what to say after seeing it build boost after you fixed it . . .other than I think I should have bought a Holset!  Great job on making her into a proper boost-eater after all those munched T3s.  Have you ever done a 0-60 run?  I bet you can get sub-6 times.

[theman53]

Low end is still not the quickest. From mid to high rpm it very quick. I am doing all the stuff to put it away for the winter, unless I emergency need it, I may take it out a few times yet, we'll see. When it is colder like it is *usually 50's for the high* it doesn't like to get up to operating temp very quickly. I built it to run cooler and it does, but if I were to run it in the winter I would have to change the t stat. I have a 160f in it and it takes about 20 minutes of driving in this weather to get to 160f, then the oil takes longer. I don't like to rip on it until the oil is right about 150f or higher. So if I take a big trip or it gets hotter I will try to get a smart phone time.
I bet it would be in the 7's for 0-60, if it is less that would be awesome.

Going to take it out tonight. Meeting a guy for a 1.5 cylinder head he bought...I want to show him that it is possible to make them faster.

Holy cow, just got this message on facebook...performance pump knowledge here. Advance curve is part but this is huge. Came from Goren the guy who built Jetmugg's record holding pump in the 1.5 land speed truck...
You have K and KF value. KF is when springs are unloaded usually 5-6mm. KF is kolben feder ib german. Piston spring. K is the value that you set with the shim under the plunger. When pump is mounted usually you have 3,6mm K at Bottom. But different lift calls for different K. Often you get it in testplan. For performance i use To set at top lift - 0.2-0.4 mm

and more...

KF is springs unloaded. Rotor out of pump. I set 0.2-0.4 at top lift and then K is what it is. For example if you have 2,8mm lift K is 3.0-3.2. Follow me?


and now even more info...

I put a shim in. Put rotor in an take pump To top lift. Mesaure from plan To plunger under the 3 size plug. If i get for example 0.7 mm i increase the shim with 0.3-0.5 mm

I apologize to wake this old thread, but madness here is just too good to be lost.
I don't know how it could be so long since last update.

Do I understand correct, Dieselmeken Goran posted you info on upgrading your fuel pump?
How did that turn out? Did you do it yourself? I mailed Goran and he 's top chap, his FB page is brilliant. 
I was reading this thread as I am studying turbo maths (PR, CFM and what the hell it all means)
read it 3 times before but just now I am starting to understand what has been achieved here.
Over 90% headflow efficiency?  ARE YOU CRAZY? Even if car is no longer working you should be very very
proud of what you have biuld.

If this thread continiues somewhere else please tell me where is the rest of it!
Is the car still runing? Where are dyno numbers?
I realize that conversation is probably continued between theman,alcaid and rabbitjockey on private but still we jungsters
need this thread to stay alive so we can all see amazing things you achieved with this little engine.
So please let us know of car's current status

regards, Matevž
