Friends, Romans & Listers,
In my contining quest to find and fit all the best parts to my Triumph, and
to help you all do the same...
I am now reviewing the question of "What are the best High Tension Leads?"
Tell us/me what you presently have fitted to your cars, What make are they?
What type are they? Are you happy with them? How often do you replace them?
Those presently fitted to my Triumph Vitesse were sold to me by
Microdynamics/ M.D. Motorsports, (now defunct/bought out by Luminition),
about 1986.
Described as "8mm Super Heavy Duty Hypalite Wirewound construction"
it says here that they are made from 8mm heavy duty hypalon-jacketed
competition cable. Fitted with high-temperature silicon and hypalon, fully
waterproofed wnd covers over spring steel reinforced pure brass terminations.
The 8mm cable is constructed by a unique method, incorporating a woven
glassfibre-reinforced layer between the high-voltage silicon rubber
dielectric and the outer hypalon sheath. This enables the end terminations to
grip through to this woven layer and be securely held against any end tension
forces which may be encountered.
A super-low resistance cupro-nickle conductor is spirally wound around a
unique ferro-magnetic core, strengthened by an innner synthetic fibre cord.
These features enable the Hypalite lead to offer unprecedented levels of
transmission efficiency, interference supression, insulation properties,
hydrocarbon and weather resistance, combined with sheer ruggedness...
(they also did a 7mm cable for less demanding applications)
(much of the above is rather stating the obvious, but that's blurb for you)
They have been in use on my car since April 97, and have just covered 5,500
miles.
I am wondering if they are still really OK?
Might they have deteriorated whilst in storage and not being used?
Should I now replace them? and if so what with?
I assume that H.T. lead technology may have moved on a little in the last 14
years?
Those offered by Cambridge Motorsport sound interesting...
Magnecor (UK) Leads:
made from KV85 competition cable designed to work at high-temperatures and
high r.p.m. 8.5mm aerospace quality silicon lead. Safe to 600 Fahrenheit,
stainless steel helically wound core protects against radio interference and
inducts electrical energy along the lead.
(sounds rather familiar?)
I await your recommendations etc with baited breath.
enquiring (sad) minds etc.
