I had a fantastic day out on Monday with the Straightliners at Elvington. I've long wanted to get my '89 up there so I could establish a standing mile benchmark before I carry out more significant modifications; aside from some minor tweaks and its different wheels, the only real performance upgrades it has at the moment are a set of long-tube headers and a high-flow centre cat – so now's a good time to get some figures in.
Originally, when shiny and new, it would have topped out at some 153mph (as far as I'm aware), presumably after a few miles. I was consequently hoping it would do about 130mph in the standing mile but it ultimately clocked a best of 144.239mph, which I was very happy with. It also did ~144mph three times in a row – 143mph was the final pass, hence the sign – so it's also consistent!
At the end of the day, I'd racked up six passes and ~260 miles on the road, with no issues. I couldn't have asked for more, especially given that it's recently endured a 450-mile trip to Castle Combe and four sessions on track.
A big thanks to the Straightliners crew as well, as they couldn't have been more welcoming or helpful. Highly recommended, across the board.
Right, time to start shopping for more speed parts...
