Been out in the car today and at least its holding boost better now. I'm still not entirely happy with the way the car feels to drive but I'm out of time now so it'll have to do for AMD. We'll see what it makes on the rollers and then I can go from there.
Got my hands on a set of polyuthrene 23mm arb bushes for £15 today, should of really fitted a set when the R32 arb went on but I was being a tight planning on having a fully polbushed car in the future.
Saying as my JR filter is still on back order with partbox, I've decided to give the K&N a clean and re-oil for AMD.
before (looking a bit discoloured):
took the BPI flow stack off:
actual filter neck size:
cleaned and lightly oiled:
Also been on the phone to Dave at Sere today to explain the N75 issue and how I thought the new E valve was faulty due to the car not holding boost properly when fitted but being better once the old F valve was back on. Dave is sending me another E valve in the post to try, before I even get the old one back to him now thats customer service
I said the exact same thing when Sam originally got one, it is rather decent. Its from Porsche mate cost about £18, they do a coolant cap that matches it but I'm after some different caps for everywhere else
