hi guys, i have been told the inlet cam on my six has been advanced, can anyone give a proper explaination of what this means, and what effect it will have on the car, (fueling ect) compared to a Normally timed engine.

thanks

it means the timing has been advanced by a couple of degrees / teeth when it was last done to, in short terms, provide a small gain in power. but really small.. i know the foreigners do it but run mad stuff like ethanol etc so would notice more gain for them i suppose

Yep, it is supposed to give slightly more power and slightly lower down the rev range too. Yes

A few members have done it here although with the ridiculously small running clearances you have to be careful when doing so.

advance = spark after tdc
retard = spark before tdc

Unsure

We're talking about valve timing not ignition timing...Doh

And even then, the more advanced the ignition timing the spark would be before TDC so you've still got it the wrong way around!

ah yes i thought we were talking about wrist watches

2 wrongs do make a right though so technically i got it bang on

i've always been a "leave it the f**k alone and don't even look at it when it comes to engine timing" type of girl

I don't think there is much to be gained in reality, my valve timing on the boosted engine is at standard settings and that's where it will be staying. Yes

next question would the fact that the inlet cam has been advanced cause the car to use more fuel, THAT is the burning question

please discuss

Hmm

no, less if anything, as it will produce more torque, meaning smaller throttle openings required at cruise.

Do you have an issue with fuel consumption then?

i played with the inlet timing, felt more torquey (a little) didnt see a difference in fuel consumption

when i did this the engine lost its kick at 4500, but as said, i felt it was more like an 8v earlier on

weird as that may sound

mine definately hasn't lost its kick, she rips your face off past that level, but now i've owned her for coming up to a year, theres been a noticeable difference in fuel consumption from when i first got her...

that could be down to a few different things, lambda, coolant sensors etc, how do yu know that timing has been advanced?
