ignition

29 post on this subject and 17 by the rob  and ml show sorry mufflerboltz this happens with these two all the time and it was a good topic start a new thread and let them have this one  its a da**   they cant see how frustrating it is

mrgoodwrench  the way i was told a coil will built only
to the point it need to jump the gap in the cap or plug
(plug wire ) no matter how big the coil is .  to make more
fire you need to open up the plug gap.

I am certain the penny pinchers at gm and ford would have not let the engineer waste the material it takes to manufacture the large hei caps if the small caps would have worked seeing you could make three small caps out of the material one hei cap takes

capacitive discharge systems hit the primary coil with 500 plus volts so the secondary increases voltage to

When a electrical arc occurs in free air space the air around the arc is turn to plasma , its a miniture plasma fireball under the cap as one would see on a larger three phase electrical scale when a electrician causes a arc flash in a cabinet that burns three or four electricians in the room around him . Its not caused by needing more energy . Its created by having more energy for the arc to jump a larger gap a msd 6  box on a 10.1 cr can jump a 1/8 inch gap at the plug and without the compression under the distributor cap (free air)it can jump even a larger gap so when you increase the energy the distributor cap size and terminal spacing needs to be increased and a vent in the cap needs to be free of deposits to release the plasma if its occuring if it has one if it dont one will need to make a vent. Go to some local racing event dirt track drag race etc . look at the ignition boxes and distributors and caps . ask why they are running a msd ford cap adapt with adjustable index rotor button.  some will probably say cause everyone else is . monkey see monkey do but for the lead monkey he will have a legitimate reason.

 Rod doesnt point out anything . He doesnt know anything about my engines or any pulling engines. He is a spectator . As for advance I didnt have any mechanical or vacuum it was electronic.  The beauty of a pulling forum is for pullers to tell and show what they have experienced to make fellow allis team pullers and their shelf more competitive. You will see post with rods sticking out of blocks  ,turbos entire blocks ran over by the rear wheels etc.  Pullers know that in the quest to win parts get took to the breaking point. Spectators in the cheap seats look for engine or component problems as a way to bash the rivals of the puller they are fans of. Plain and simple.

I havent been in the stands at tractor pulls and my tractor when i pull it makes more than appearances at one goto

They are already on the forum in the archives. I can repost but it would be repetitive.

Pictures are in photobucket under pankeyc.i am away and on my phone. There is also a hei a msd 6 box and blaster two that i posted in the classifieds. I run a msd 7box and hv coil with a p1000 pontiac hei modified from a computer controlled p1000 so theres no advance in the disrributmor. Distributor is locked at total timming with msd two step pulling timing if needed.

Rod you know that in the archives when picture first posted that plumbing was temporary function trial. After all some was saying the oil pump would blow the oil filter off but it didnt. Its good to have extra oil pressure when doing a competition clearance setup. Dry sump is the only way to go on a rpm turning stroker you wouldnt believe how it scares individuals.

I know and he avoided my question as to where we can see it run.

His RPM turning stroker was governed at 3000 before someone showed all of us how to turn one hard.

Guy is full of bs.

Last excuse for the hideous plumbing was for drain back. This time for pressure. But it's a stock base which accepts many common filters. Pressure argument is pointless, excesive pressure is only wasted power. With those wide berrings less pressure is needed, they have enough drag the way it is.

Couldn't be much of a stroker with straight cap rods either and a stock oil pan to clear.

Just how excessive of an rpm machine can it be with no safety equipment?

Experience and truth are powerfull allies

Heres some pics of the ignition system we are running, distributor is from a 2.3 litre ford engine commonly used in rangers and mustangs. Pretty simple turned outer housing down in my old lathe then shortened shaft slid gear on and drilled new hole for the roll pin. Then used some wiring from donor vehicle and the ford box. A msd box could just have easily been installed, but we had the ford one. Did away with the vaccum advance and installed light springs on mechanical advance so they would open up sooner. Waaaaayy better than the fairbanks morse mag that was on there. Wc block, 45 crank, flat top pistons, bigger valves in the head.

D21 its the same to make the hei work. Just dont have to have the box unless your wanting more spark.   The allis 226 flat cylinder head and flat crank is the automotive rage for 2012/13 but some try to reinvent it to the 80s instead of things that need to be upgraded to the, 980s like ignitions.
