Yes, it's true, she's not as powerful as she used to be, but remember, before she went to Peter, her engine was run in and piston rings were sealed.
Since the rebuild, we've dropped compression on her. She no longer runs 11:5:1 compression. Also, the piston rings have not seated yet. Chrome Moly rings need at least 5000km before they start sealing. Our compression test shows all cylinders are down on compression. The car has only done 3000km since the engine rebuild. So, last night was a nice test to see where we sit with a motor built for boost that has no software. I'm patient and thoroughly enjoyed my races last night. I haven't driven her like that in a good 11 months, if not longer.
That being said, after dynoi'ng the car, we've discovered a massive dip in torque at 3200rpm. Almost 40nm dip. Also, max torque is 270, as opposed to +-300nm that we used to have.
We keep getting intermittent Vanos codes when we read the car using INPA or DIS. One of the codes we keep getting is a code 95. This is a code I was getting even before the Engine Rebuild. Code Error 95 is Vanos inlet adaptation. This means the inlet cam does not advance, so, once I hit +-4000rpm, the inlet cam is retarded. It should be advancing but it isn't. So, I lose top end power. (Peter can give a better explanation of this).
So, to save us a massive headache. Peter will be replacing pretty much the ENTIRE Vanos unit. It's up to him. So, I'll let him update from here and we can start testing again.
More to come...
