Low to Mid-range torque will return and smooth out again.
Vanos do nothing at high RPM
problem with a dyno is getting comparable before and after runs... procedure takes time so dyno conditions change...
then we also have to factor in travel time to and from the dyno on the day it turns into a mad rush...
then there will always be the debate on the numbers... fact is we could easily 'tilt' the numbers to get the results we want...
would love to do some dyno numbers to prove the difference but in practice it is not so easy and the results would still be questioned...
every customer is happy and feels the difference this means more than some abstract numbers at the end of the day :rollsmile:

A big thank you to Alex and Peter for the excellent work. I think I had quite a custom job done , so thanks again for that extra effort !
The engine is so much more quieter and has a sweet rhythm to it. It was different for me on first drive though... although the car felt quite strong, it was a bit tight through the rev range.
I drove the car to work today and on the way home in sport mode pulling the car every stretch I could, it just started opening up. It got smoother through the rev range, the throttle response was getting sharper ... the exhaust note was just so sweet and there were crackles on gear changes.
raise:
I've only done 120 km total since I got the car back. I'm sure the more I drive it the better its going to feel! I'm only reving to 7000rpm for now, can't wait to unleash that 1500rpm ! :rollsmile:

I will now proceed to post what we found in this car.
As a footnote please let me assure you that the car is running Sir Greek cams as already divulged by Andy.
This is the first car we have had with such severe vanos issues and I for one am totally surprised that it was not throwing all the vanos codes that it should have.
This is a series of pics on the vanos inlet bore which was scored with hardened oil residue and seal material.
The oil pump disc which shows clear signs of the tabs indenting the holes.
Pistons fitted with new seals.
Look at the earlier pic to see the difference in fitment of seal around the piston.
R
Ready for valve clearances.
We did a custom shim for this car as it is known to rev freely so we wanted to enhance the "revability"
Rattle kit was not required we did however check the cam gear bolts to ensure that they would not come loose.
All were found to be tight.
Work completed with new holes drilled on the oil pump disc new seals on vanos and cam clearances done.
The silver thingy that goes on top of the engine to keep the oil in.
The other silver and black thingy that makes a lot of noise.(In the background you can see a portion of Jezebels rear)
Almost ready to go back to its owner.
