of an RV8 power steering conversion
David Driver has enjoyed MGs for
much of his life and was delighted with the RV8 he has had for the last two years
but found the steering very heavy. He sought the views of many fellow RV8 enthusiasts
and encouraged several threads on the V8 Register's bulletin board on the topic.
He found the quality of the technical and insurance disclosure issues raised on
the board were very helpful. He had read Peter Garton's detailed workshop note
on his RV8 PAS installation prepared following his conversion of his car back
in December 2005. David also considered fitting a castor reduction kit to achieve
lighter steering but in the end decided to have an electro-hydraulic PAS system.
The RV8 PAS conversion was carried
out in March 2008 and as soon as the car was returned from the workshops, David
took the car out on a test run. He found the steering effort much reduced and
the RV8 was a pleasure to drive. This was particularly the case at slow speeds
where previously the heavy steering had been an unattractive feature - particularly
for someone like David who describes himself as "not in the first flush of
youth!" You are soon aware of two noticeable changes - the self-centrering
effect was not quite as before, but not something he could not get used to, and
there is a slightly increased turning circle.
One of the major changes
in the PAS installation from those on earlier RV8s, like Peter Garton's, is the
hydraulic oil reservoir and pump have been moved from the engine bay, located
over one set of exhaust manifolds, to the front of the car. Four advantages are
cited - first there is a cooling effect on the reservoir, second the filler cap
for topping up the hydraulic oil is very conveniently located just under the bonnet
at the front, third the system appears quieter in operation as the pump is further
forward from the driver and fourth the relocation overcomes some of the earlier
safety concerns of an oil reservoir over the exhaust. Naturally there was concern
that anything upfront might affect the cooling airstream to the radiator on the
RV8 so David discussed this with Roger Parker. His
view was that
"locating the reservoir and pump there may
affect the cooling very slightly but as the principal airstream is below there
is nothing to worry about".
is delighted with the workmanship of the conversion and feels it was a professional
job. He also values the informed support from Roger Parker too who has been very
happy to talk over a number of the technical issues with David. The installation
took around 18 hours, costing around £2,350 including VAT although the quotation
states that additional charges may be made should parts be found that need replacement.
David elected to have the RV8 collected and returned by special covered trailer
so the car rolled on to his drive spotless.
Finally David contacted his
specialist classic car insurance broker and formally disclosed the modification
made to his RV8 following the PAS conversion. He had previously obtained confirmation
from Peter Best Insurance Services that the insurer would accept an MGOC electro-hydraulic
PAS conversion fitted by the supplier's workshops and was pleased they would not
require an adjustment to the premium or impose any additional policy conditions

2005 - see Peter Garton's detailed report. RV8NOTE235
