if not, i bet they would make em for the porsche, considering pepole with porsches might have more money.

OH... Yeah, I have heard the same.

Plus their set up is still pushrod driven, or at least it was last time I looked at it. They used to make a TI exhaust ported TIV head, but it had some serious cooling issues.

Hi,

wanted to give you an update on the status of the Bug @ 5-Speed 4V DOHC-heads.

Robert Bernauer, my partner in this projevt, now did the first few flowbench tests with the heads. The results are really impressive and we expect a very good performance of the engine. The heads with no adjustments made (only mounted) were already better than the best type 4 race heads he compared.
He made 3 further tests with each time smaller adjustments and the flow data let us hope on a very good performance of the engine.
Flow at 25" is:

1mm - 38,2
2mm - 70,9
3mm - 107,9
4mm - 144,1
5mm - 183,3
6mm - 210,7
7mm - 230,7
8mm - 245,8
9mm - 256,0
10mm - 263,7
11mm - 267,6
12mm - 272,2
All measurements without manifold.
12 mm with a primitive manifold 285,4
13 mm with this manifold 289,1.

There are still some things to be done, so that we can expect a further improvement. But even if it stays like this we are very satisfied with what we have.
Next week I will finally have the die/mold for the manifolds. As soon as we have the first casted manifolds Robert will test the whole range again with manifolds.
More info to follow.
