Aye Scott next door has one of those, only thing is he left it for a couple of months and the metallic 'Puck' clutch has rusted to the flywheelIt was an Aquamist system , plus all the other bits to keep a 400 BHP Impreza on the road.
Roger Clarke Motorsport
You can certainly tell when he fires it up though, the exhaust isn't that loud but the house vibrates when it's running and at 'tickover' it's worse, when he revs it up there's a bit but ticking over it is unreal.
BTW I actually knew Roger quite well, in 1985 I worked ar 'Clarkes of Narborough' (the old family works) and the bodyshop was there for sticking Porsche cars back together, by this time Roger was into Powerboats and had 'Roger Clark Marine' just down the road on 'Cutters Close' near the 'Roger Clark Cars' Dealership on the corner of Leicester Rd. and Huncote Rd (where I lived) Oh and the 'Roger Clark Cars was his brother Stan's pet project with Lotus and Porsche dealerships.
I probably spoke to him a couple of times a week, a very 'larger than life' fella (and a big bloke too) and at the time driving a Range Rover, but then his Dads old garage was an Austin Rover dealership
