I haven't been whipped by anything for a while. I remember taking on some kind of quick Audi in my Saab a few years ago, and lost, but that wasn't really a whipping. Was racing to a merge in turn and they got infront by half a length or so, so I conceded defeat and backed off for safety reasons.
Another time, in the same car, I kept up with an escort cosworth to around 120 up the sliproad onto the M1 at junction 26. However, we weren't really "racing" just both put our foot down as we went up the hill. I was actually surprised that I could keep up, so he couldn't have been trying much.
The cerb hasn't really let me down yet, despite it running like a bag of spanners, with a slightly slipping clutch and godawful geometry and damping.
I played with an E46 M3 the other day, was reeling him in up to about 90, when we both seemed to decide, about the same time, that 90 in a 70 was fast enough and he pulled over to the other lane just as I was starting to back off the throttle.
I can't wait to get the cerb properly sorted. It'll go like stink then!
