Rolling Road North Lancashire?

[sparkythecat]

I've had my 98 Chimaera 400 for 4years now. It's done 36k miles and has been regularly serviced at the factory.

It may just be my my own perception, but I'm quite sure it's not quite as sharp as it used to be. I'd appreciate any recommendations of where to take it locally for a full medical.

That's only about 13 miles away, I'll check them out.

I asked about a rolling road , because I understood it to be the best diagnostic tool.

Have I been mis-led?

Crikey, I've opened a real can of worms with this thread.

I have no experience of rolling roads but my understanding was (and I'm more than willing to be corrected) that you put your car on one so that the engine performance could be dynamically tested under load using diagnostic equipment in controlled conditions.

A graph of the engines performance is then compared with performance data for an identical 'ideal' engine

Adjustments and/or modifications can then be made and any improvement accurately measured, because the same engine test procedure can be accurately repeated.
The results should be more scientific than any subjective view from comparitive road tests.

I certainly don't want someone to repeatedly rev the bollox out of my engine on the rev limiter in an attempt to count every last pony in there.

On a lot of the dyno graphs I've seen posted, bhp and torque curves rise, peak and then begin to fall.

Can't really see the need to keep increasing engine revs once the figures start to dip.

A normally aspirated engine isn't likely to get its 'second wind', is it?
