I understand the turbo will make a difference, but no matter what pressure the air is under it will still act like a sound wave in the runners. I don't understand it fully, but from what I gather the big factor is the camshaft duration and that the air is traveling at the speed of sound...so it acts like a big spring until the valve opens and at that point it will be forced into the cylinder. The little bit of reading I did I figure it will still be under 3,000rpm. If this spools like the k24 did I had 24 psi before 3,000, so the theory should still be on target. Even with no boost present I am hoping it performs like the N/A mechanical engines I had. The N/A manifolds had very long runners and seemed to do well right of idle, so if this just mimicks that I will be 100% satisfied and will call it a success.
I will not be butt hurt if it doesn't work 100% as planned. I did it for 50.00 and time, so I won't be out much. Plus it would be 10x easier to make a dual plenum that is shorter than this was to make. I am pretty sure it will be better than stock so that is worth it to me. If it for some reason is complete garbage I am just a cut off blade away from shortening the tubes and adding the 2nd plenum after capping the inlet. I would love to send this to someone with a dyno and have this tested vs other intakes and see what the comparison results are. Also then a real world driving senerio to see which design the butt dyno prefers.

It is good you won't be butt hurt because that effects the accuracy of a butt dyno

This has been the the bag since December of 2011. So a touch over a year. I figured I should pull it out. It is the key to this build. I honestly don't know what is in it but there are some parts from the TDI I guess. I just told him to make it fuel so much I melt it down if I lose boost. He said OK
Some day I will have my head back and this will go together. I put in the heater core today, so most of the inside work is done. I will have heat too.

Until its all together id make sweet love down by the fire with her.
I hope it has a nice fuel lope.

I just hope it runs someday soon. I still need head.
I would like it to run good too. If I can light the new T3 hybrid that I have even 100 rpm earlier I will be happy. Which with the manifold I have I think it should work. I don't want it much sooner than that as I think I will have traction issues.
The inlet is too big for me to be making sweet love to her down by the fire, lol

We will find a way to spool it LOL

This is John Deere green. Seems pretty close to the stock color. I am over it. I like white now.
If you can, obv you should powdercoat everything you can. Painting things sucks.
And it all gets ruined in the end anyway.

Did you ever get the manifold flowed? That 90* bend where the stock manifold flange meets the tubing looks highly restrictive.

No, I never got it flow tested. It is the stock 90*. It looks more restrictive than it is I am sure. I ported all the weld through out and it isn't an L it is more of a C shape to get the air in there. As stated earlier, I won't claim this is the 100% answer to all 8v vw diesels but I know it will be better than stock. I took it all up to my machinist that does stuff like this and he said it should be great. It wasn't together so I didn't have him flow bench it, but he has designed and made similar with good results. I won't take it to get flow benched either as he has had my cylinder head for a year now and I don't want him to do anymore work without that being done...no more excuses of too much to do.

Talked to the machinist today. The head should be done by this weekend. Now I have to get ready. I ordered a smaller intercooler, for giggles and will probably be ordering a new radiator for more cooling. Also, I need a 2 pin 210mm flywheel if anyone has one that would be excellent, let me know. I also need to clean the surface rust off the deck surface, sucks, but what do you expect from a block that has been waiting for head since August.
I cannot wait to get it flow benched. Or running for that matter.

It may be somewhere in this thread but I have to ask - why in the world has it taken so long to get the head done?
Just curious.
Can't wait to hear how the new manifold works out.

There is a story about the head, but I am holding off on telling. It is not close to a stock head any longer. I asked if he could do what I wanted and he said sure. The more in depth we got the longer he stretched it out and I think he was wanting me to say forget it and just put it together. If it works I will let you guys know what is up, if it doesn't I will keep it to myself.
I will post the flow bench numbers when I get them, that should be impressive to the point that people will say that it isn't possible for a 1.6 head to flow that much.

OK, starting to get it now. This what I really enjoy about this forum - many of you push the envelope and there's nothing like that feeling.
I hope it surpasses your expectations sir, you really have stuck to it.

Even if it doesn't work, I think you should at least post something explaining why it didn't. This way, we have evidence of what doesn't work with a particular setup; evidence of something working is just as good as evidence of something not working. It might be a little macabre, but a failure might be better to discover the limit of the 1.6 head.
Not jinxing you, though.
it's about time the head was done!

If so I will be very general, I won't go into detail as I want to have some sort of mystery to it. Either way I guess
