Hello Joseph,
I drive my Jensen Healey whenever I can except when there is salt on the
road or in torrential rain. I like driving long distances, OK noisy as
hell, but I wear ear plugs. I have been to France, Belgium, Luxembourg,
Italy, Switzerland, Germany, UK etc. sometimes driving in excess of
500km a day. Next year there will be a trip to around Dresden organised
by some German Jensen owners and enthusiasts and the International
meeting in the UK.
I too prefer the smaller roads but occasionally I take the German
Autobahn to clear the engine and have a prolonged blast of 150-160km/h.
Faster is no fun as the car starts wandering a bit. I do use all 7000rpm
of it through the gears.
Our cars are made for driving not trailering. Parking in cities can be a
problem, but I usually look out for a spacious parking garage or a
hotel. So far I did not have any problems.
The only trouble I have had in my mildly modified car has been a blown
fuse preventing the electric fan cutting in and causing a fantastic
cloud of steam when I stopped the car after some stop & go traffic. Took
me about an hour to find out what was wrong, but once found it was
rectified in a couple of minutes. Luckily no harm was done.
Mods: slotted brake discs, Green stuff pads, more efficient radiator
core, hotter engine thermostat, thermoswitch controlled radiator fan,
electronic ignition, modified steering column, larger and wider wheels
with modern tires, bigger 45mm DellOrto's, timing belt and wheels from a
late Lotus Esprit, adjustable cam wheels, LED lights where sensible e.g.
in daytime running lights fitted in modified front indicator units, Koni
shock absorbers, electric fuel cut of etc.
Future mods: front suspension partially rose-jointed, 4-pot callipers
and ventilated discs, installing an intercom, 5-speed Getrag.
I am presently building up a new engine with high compression pistons
(from 8,5 to about 9,5) and may be some mildly hotter cams.
Cheers,
Kees Oudesluijs
