RE: Audi A4 1.8T - Queston Regarding Turbo Behaviour
if your all stock you really wont feal the turbo at all. the car is tuned so that you can't tell you have a turbo, it boost up smoothly and as soon as you get it, it goes away smoothly. And torque = boost isnt quite right, k03 spools at like 2200 at the earliest

RE: Audi A4 1.8T - Queston Regarding Turbo Behaviour
This may be off the wall, but it's something I ran into with BMW enthusiasts when I was in the UK. 95 Octane in Europe is about 90 US. Most of Europe uses the RON (Research Octane Number) rating. We (the US) do an average of RON plus MON / 2. When I was in Scotland, Super was the 97-99 octane petrol and was preferred in sportier cars. BP and Shell also sold 102 RON at certain stations, usually on the main motorways. Also, your motor may be tuned differently as the emissions standards are totally different over there. I was sad to come home back into a US-spec 328i after being spoiled by the European levels. I'd check with a local dealership if there is one as to what fuel rating they recommend. HTH

my engine layout is different though . I checked all the piping and it looked sound.

yes disconnecting the batter and discharging the system will erase codes, and you should definately feel the turbo and hear the boost, 01 a4, its clear and distinct, not like a huge honda or mitsu turbo but with the windows down it sounds kinda whistly i guess to say, and you should get boost if you have a gauge in any gear around 2200, and even when it was stock you could feel turbo spool up, so i dunno what you guys are talking about, when shifting it should only take about 400 rpms to spool. thats what the k03 is designed for.

well, I haven't driven a 1.8T B6, so I don't know first hand. but according to audi, B6's (well 2002s at least) develop their maximum torque of 166 ft/lbs at 1950 rpms. boost = torque. having said that though, AEB engines are supposed to generate their maximum torque (155 ft/lbs) at 1750 rpms. I question that though, my car is anything but torquey at 1750 rpms. [&:]
I think I'm more confused now than I was before I read this thread. [:@]

I may be a nub, but "sooner" wasn't what I was looking for. What RPM range are we talking about?
sooner. VVT helps with that.

Well, I have never had a car with a Turbo so I am still getting the feel for it . Maybe I am just not driving the car correctly , to get the maximum benefit from the turbo .
I was driving home tonight from town , about 60mph in 5th gear (around 2500 rpms or so ) . If I floor it , it picks up speed , but nothing special . When I dropped her to 4th and floored it , it still didnt blow me away (again i am not used to a turbo so, maybe I am expecting to much) . I slowed her down to about 40mph and dropped to 3rd , acellerated hard and I hit 60mph pretty quickly allright ..
Sound about right ? I might drop her into the local Audi dealer and get them to take a look . Maybe she needs a tune up ? There is 70K on the clock.
thanks

your in a 3000+ lb car pushing a little over 100 hp to the wheels.
