on the V8 website on
the Pertronix replacement electronic ignition system on an MGBGTV8
Fitting an
electronic ignition system as a replacement for the original contact breakers
to obtain improved ignition performance and reliability is a modification many
V8 enthusiasts will want to consider. But what are the electronic ignition options
and what issues have fellow members seen when fitting a Petronix system. So here
we have a "gateway webpage" to the useful information on the V8 website.

Points adjuster modification described alongside.
The Pertronix Ignitor system is a compact and neat installation fitting entirely
within the distributor. No external box of electronics is required, but you do
have to bring a 12v ignition feed wire ( by-passing the ballast resistor) to the
unit. The high voltage coils also require a full 12v supply.

Petronix
upgrade with a new distributor
What
a pleasure driving the V8 is now - it pulls smoothly and confidently
from low revs and runs crisply with a zest on the road. Fitting a
Petronix Ignitor to an MGBGTV8 distributor has got rid of an irritating
misfire - a real transformation and a smooth V8 engine, just as it
should be! 120316 More

Brand new distributors available for the MGBGTV8
The Distributor Doctor has fortunately
acquired a few brand new, UK made Lucas 35D8 distributors in the earlier
style complete with points and external dwell adjustment with the
hexagonal bar. They also have the original vacuum advance unit with
the offtake midway down the slope which is exactly correct for the
MGBGTV8 model. The centrifugal advance curve is also correct too.

Feedback from Pete Thomas
Pete Thomas thanked fellow members for their prompt replies
to the emails on the Pertronix option and for setting up a workshop
note on this. He hoped that the combined experience will now help
to resolve some of the issues that V8 Register members have recently
experienced with poor quality condensers and points and worn distributors
- his main reasons for going to an electronic system. It is not cheap
to replace the ignition system but it should pay for itself in improved
economy and parts as he intends keeping his V8 for a long period.
Unfortunately, the wear on the distributor (his had done 150k miles
from new) necessitated a re-conditioning which is much more expensive
but important for many reasons including better advance accuracy,
better system earthing and less wear on the rotors and covers."
Points adjuster modification
When fitting
the Pertronix kit you need to remove the spring from the points adjustment
screw and tighten the screw as far as possible. Note: the adjusting
bolt is not removed, just the spring. More
V8NOTE435 - Pertronix electronic ignition queries
Pete Thomas was having a V8 distributor serviced prior to installing
a Pertronix electronic ignition set up as a replacement for the original
contact breakers. He had a few queries and sought help from the V8
Register saying any guidance you can give regarding this will help
and Bob Grieves responded. 110830

More on V8 distributors
Gordon Hesketh-Jones (Harvest Gold 1904) from Cornwall has clocked
up more than 400,000 miles in his MGBGTV8 so has had a higher maintenance
workload than many fellow V8 enthusiasts. He also uses his V8 for
touring in Europe so reliability is a key concern for him and one
area is the reliability of his ignition system. As an update on his
earlier V8NOTES on this topic, Gordon reports his experience with
fitting a Pertronix electronic ignition system. 080601

V8NOTE365 Distributor options for the MGBGTV8
Gordon Hesketh-Jones (Harvest Gold 1907) from Cornwall uses his car
all the year round and with a total mileage now rapidly approaching
400,000 so has a great deal of experience of maintaining the model
from his regular servicing work and numerous rebuilds. One regular
service difficulty is with worn distributors, so he set about some
research into the options for the V8 which he reports on in this note.
