That still seems excessive. If anything, I'd expect the 020 to be gernading out of any of them, especially with 100% Mission usage. At AMP, there's plenty of straighter sections, particularly the lower back straight, where there is lots of airflow for a good duration. I remember a mk3 dominating when I used to go there 5-6 years ago. Fantastic track, but it was getting really bumpy. Loved the track garage and hoist.
What oil were they using in the trans?
