Well guys i got around to putting my crank pulley on today, and holy shit was it bigger than the A3's!! i had to use a junk used dayco belt for now, but it's peaking around 10psi with some slippage so my guess is 11-12 or so once the bug is fixed. but there was one problem for people that want to do this on the A3, i ran into a problem i didnt realize until i first started it. there is a bolt on the timing cover than comes in contact with the new pulley, and i didnt know. i start the car and look under the hood and i see small sparks and i am dumbfounded, 2 seconds later the sparks go away and the smell of the coating burning off the pulley resides. it ground the head off about 1mm or so. so if any of you look to do this, take care of the problem before hand. anyway, the blower whines like a cobra now :)
