Flowed both head and headers
#1
Whilst flowing my headers today, i also did a run on the exhaust ports. Took away alot of material and worked inward about 3 cm.
I'm very pleased with the result, i gained a lot of tourqe in low and middle rpm:s and slightly better at top. The driveability wich was already with TeK2 a dream is even better now.
Along this, the burbly headpounding sound is almost gone, much less struggling. I'm very pleased indeed.
Boost raised almost 1 PSI also.

I made 4 fluffy ***** of wool, wrapped i cotton, and pushed them gently in towards the valve-shafts. I did not get anything above those. Really simple and definately worth it!!

Sounds good Did you go right out to the gasket diameter ? Reason I ask is that I've no idea how close the cooling jacket is and would not want to cut into it
Did you notice any difference in the RPM the turbo hits full boost at ? Mine is spooling much earlier but I modified the intake at the same time so I'm not sure which one made the difference

seems like everyone is doing it this week
did mine over the last couple of days, i got it ported to the gasket diameters, i've got some photos of before and soon to be after (just needs a final polish ) i'll post them soon
not had the chance to check any performance gains due to lack of gearbox on the car

John...yep, i'll log it. I talked to David some time ago, he said they had a better TeK upgrade for me when i've done the heads and headers, so i'll just send my logs and upgrade.
Edit: worth mentioning, i always run a 102RoN mixture

I ported almost to the gaskets, 1mm left around.
It spools quicker now, haven't noticed exactly, but around 2 -2100
with a lot of bottom tourqe before that also
