Re: [DML] Farrar's distrubutor - theory.

["cbl1739" <cbl302@xxxxxxxxxxxxx>]

It's quite obvious what happened,he installed a high output ignition 
system,coupled to a basically stock factory distributor,trying to 
pump out a massive electrical charge to a quite oversize plug 
gap.....times six cylinders,that is fine for a short period,but like 
the HEI ignition systems (High Energy Ignition)used in GM cars in the 
1970's and early 1980's THEY quickly broke down the contacts in the 
system...but with the HEI system everything was MATCHED to work with 
one and the other,so it was just a matter of Cleaning the 
contacts...But in this case since the "weak link" was the Distributor 
and in particular the factory Pickup coil(inside the Distributor),and 
Ignition Module(or just 
old/weak)...they simply were not up to the task for ultra high output 
with such a big demand(for the oversize plug gaps)which in turn lead 
the Capacitor to  die,now you have this surge of current,that builds 
up between firings,that has nowhere to go but through the Distributor 
Module/pickup coil...which it cannot handle anymore,the result is 
MAJOR internal heat up/melting/fire inside the distributor,from the 
melting plastics.

Something similar to someone at home trying to run a high output amp 
to a low power stereo with high performance wires into stock stereo 
speakers..something is gonna overheat/melt/BURN!!!!
