I had a strange feeling of 'what have I done' when we arrived at Charlie's place, odd when you consider that it was me who had arranged to come here in the first place.
It was all right for the other guys, as they were all running borrowed cars, but this was my own pride and joy and all I could think about was rolling road horror stories.
To calm myself I raised my bonnet and pretended I knew what I was doing as I made 'last-minute checks' on my engine.
Once the TVR was strapped down, I watched as it was put through its paces, and a first-run figure just shy of 240 raised eyebrows around the room. One more run was all that was needed to get 240 on the nose.
To say I was happy would be an understatement. I have a car that I love, it's on the money power-wise and everything seems to be in order as the factory intended. Not only was I grinning like mad, I could now relax and watch as the other cars had to reach the high standards set by my 11-year-old TVR.
Having the stupidity to swap my four wheels for two - and powered by legs - for a cycling trip, I passed the keys for the Nissan to Mr Will to take it to Surrey Rolling Road. Under the strict promise that he wouldn't take it for a 'cruise', as these young boys seem to like (though I should perhaps have clarified the definition of this with him - it had me worried when he said he only did that at the weekend).
Now, rolling roads are subject to ambient weather conditions, but comparing the other cars' base figures and the writing on the little paper printouts I am pretty pleased with the Zed's vital statistics.
Mind you, I can (and will) make the excuse that it's still pretty new, so the engine might be a bit tight - and anyway it still bettered its manufacturer's claimed power. Unlike a Certain Mr Garlick's car, which merely reached its target...
Caterham says my Seven Roadsport 125 Academy racer ought to be good for - and you might already see where this is going - 125bhp. Sadly, on the rolling road it could be coaxed to a mere 118.1bhp, and a torque figure of 113lb ft (factory says 120lb ft).
I'm not too fussed by that, though - Charlie reckons most Ford Sigma-engined Roadsport 125s come out around there, and my car certainly doesn't feel down on power. In fact even with a chunky Riggers pushing the weight up to near-enough 650kg, that still makes for 182bhp per ton - within sight of the far more powerful 370Z's 214bhp per ton.
Chris-R - BMW M6
Up to now my experience of dyno has been limited to the odd YouTube clip, and I must say I was looking forward to 'maxing out' our BMW M6 on Vixpy's rollers.
Disappointment number one was that it's not a DIY operation, as there's a certain amount of skill and experience required to get proper results. Not to mention the 'elf and safety' aspect of launching one's bolide off the roller platform and into the spectators. (Vixpy reckons it's never happened, but there's always a first time - either way, he does the 'driving' himself!)
Talking of numbers, Vixpy predicted a figure of 450-460bhp for the M6, based on previous customer cars that he's measured. So it was with some surprise that we clocked 489bhp in third gear with the M button pressed, which was very close to the 500bhp figure that BMW quotes.
Not as pleased as I would have been with the 529bhp figure generated by an initial fourth gear run. For reasons I don't quite understand Vixpy reckons fourth gear always gives dodgy result on the M6, and so wouldn't issue a chitty... the spoilsport!
