Thoughts on mTDI AHU head porting

<< < (3/3)

jhax:
I do have an intercooler

jhax:
Exhaust port on head gasket side before:


Exhaust port on head gasket side after:


Overall first porting on headgasket side:


Exhaust ports before and after on manifold side:


Other two:

Final product:


I ended up smoothing out the exhaust ports to keep airflow as laminar as I could. While keeping the intake ports dimpled in order to promote turbulence for more efficient AF mixture sooner.

RabbitJockey:
looks good, did you do anything in the intake bowls/seat area? it looks like you opened up your exhaust more than me. i wish i had done it more like yours, but i was trying to keep it simple.

how much time did you get into it?

jhax:
I opened the intake bowls a little bit, I was more focused on the exhaust though, although Im not sure if it will help due to the fact that smaller ports would allow for exhaust gasses to get to the turbo quicker, fluid dynamics and all. But we will see what happens.
