Just a quick question really, as I'm popping over to a rolling road in a few months as one of the yearly events we hold on a site I run, and I'm tempted to ask how much he'd charge to advance the cam timing.

People have managed to gain what seems like an extra 10+ lb/ft but with power dropping off earler at around 6500 or so from what I've read, but it's a bit vague.. How long does the process normally take if they were able to do this (costs??), and are they're any other negative or positive effects with doing this and does this improve torque in the lower or more mid range?

Thanks, Ry

power doesn't really drop off any earlier, Peak is at 6.5k on a standard engine.

you get more torque pretty much everywhere which makes them a lot quicker than a high peak figure.

All you do is take the belt cover off, slacken the bolt/s, turn the cam a little, and tighten them back up, never seen any hard figures as to how far to move them from the standard timing though.

Bear in mind that 1 degree at crank is 2 at the cam.

Any more thoughts since last night on this Mei? I think it would be worth you looking at mine to see how far Andy advanced it. I don't find it drops too much high up the rev range - I change just before 7k. You do lose a power kick in the mid range, but actually it is quicker everywhere.

A lot of the feeling of more torque in mine you feeling I think was maybe the 16 odd kilos lost by the lighter wheel/tyre combo.

It feels a lot smoother now than it did before, quite hard to tell, you definitely lose the "kick" but feels a lot stronger from 3-5.5/6 where it used to be very noticeable at 4.5-5.5.

I do have smaller lighter brakes, but I think my wheels make up for it as the 6 brakes wont fit even though they are 15"

Doesn't help that I have the later single bolt pulleys, a little more tricky to get accurate measurements. shall have to measure exactly how much I moved them as I just did a "see what happens when I give that a nudge" LOL

Edit, also doesn't feel quite as eager to headbutt the limiter, but that is 7400 on my ecu, the exhaust cam was a little advanced over the standard pinned setting before I adjusted it, its back to the standard setting on the exhaust now.

No idea on my pulleys, just whip off the cambelt cover when you're next over this way and have a gander. Sounds similar to mine - I thought it was slower first time I booted it without the kick, but then thought 'hang on i'm going pretty quickly all of a sudden'. Sure my exhaust cam is advanced too Smile

No one has a graph to compare the curve? If it's that easy I may just get a run done, and then get it advanced and compare the difference for you all to see Smile

nope, nobody has yet done a back to back comparison on a RR, not that I know of anyway.

its a lot easier to do if you have the 3 bolt pulleys Smile

i presume you have to take the cam covers off to turn the cams? its not just rotating the pulley's.
do you have to lock the timing before you do this. an FAQ would be good.

if you're a numpty its best to leave alone LOL

no need to tame the cam covers off, just the timing belt cover, it really is just moving the pulleys a little bit.

update on progress with mine, seems to be using less fuel on the cruise, and now I've adjusted the throttle cable one notch so I actually attain WOT, it feels much beter from 3.5 to 6k Big grin

ok so once the cover is off, slacken the belt? loosen the cam pulleys. rotate clockwise by about 1 or 2 teeth?
should this be done with timing pins in?

leave the belt alone, slacken pulley bolt/s, turn engine back whilst making sure the cam stays still, I think its half a tooth at the most.

secure pulley, turn over carefully to make sure it doesn't bind and that its moved how much you want.

I'm not sure yet quite how far you can go with the standard pulleys and how close the vales are at TDC.


EDIT, note this is a lot easier with the 136 tooth belt and metal tensioner, and the 3 bolt cam pulleys.

So does anyone have any info how far you can, and what it the best amount to advance either cam or just the intake? ie 4degrees etc.

Slight thread bump - can anyone help?

I have a Ph2 GTI6 I bought a while ago and was immediately taken with its performance - it went like a scalded cat. I bought another Ph1 6 and was disappointed that it wasnt as quick, and assumed that my first one had some funky cams or soemthing as it was very lumpy on idle.

Took it to have a cambelt replaced and its come back slower, the same as the Ph1 Sad

I took it to a specialist to have the belt done, who tells me:
"The timing pin holes to time it up were all pinned to start with and pinned again to fit the belt so as far as the timing goes its not been changed"
"before the belt is removed the cams and crank are locked and then the belt is replaced"

From reading this thread and talking to a mate who had the same thing, Im convinced the cam timing had been manually advanced as detailed above - Im not suggesting the mechanic has done anything wrong, but would it be possible to return the car to "standard" by doing the above??

To fix it, I guess its a case of rotate the cam very slightly again - is anyone confident enough to do this??

Please help - I spent more than I paid for the car soprting out the cambelt and suspension and its come back slower, particularly between 6-7K where it used to go apeshit.

Update time I reckons. Smile

I took the car to Carl @ CG and asked him to advance the cam as detailed above - got it back and its like a different car, much quicker through the revs, pulling much harder and has a much better top end.

In comparison, the "standard" 6 I have feels pretty sluggish - Ive not run them side by side but I will do and will probably film it as I believe the difference is very noticable.

Only downside is the advanced car has rubbish fuel consumption compared with the standard one, but I can live with that Big grin

    Advance both cams yes and it made no difference at all to fuel economy on my car, just stop booting it everywhere now its quicker Razz

    Absolutely worth doing imo - been saying it for nearly 4 years now and its rarely done by anyone LOL

    Going to investigate the V6 cam advance soon too Ninja
