Anyone know which ones fit on a cossie and are reliable?

 

a what??

 

ForeignRS and AustenW both use/know about Coil on Plug I believe (with turbo application), main thing you'll need is the management to run them!

 

Managements sorted

 

NONE of the ones ive seen fit on a cossie engine unless you have a smal turbo head as you cant access the leads, but if you DO find info them please tell me as i wanna do this on my cossie engine

 

watch this space

 

i haven't done it yet, but i've got all the bits together now to do it

not ready to give away the secrets yet though, otherwise prices will shoot up before i get a good stock of spares

 

i will be doing this also

 

 

the only gain as i see it is long plug life

and on 701's.. who gives a shit

 

I got mine from here.

The BAE 720 should fit but there £100 + Vat each

 

Selling this for the Zetec at the moment

£200

 

I wondered why all the old posts were poping up

 

What you doing on here?

 

I cant see the point of it.

Take a coil, which likes being in a nice cool environment, and stuff it inside a cam cover, just so you can get rid of an ht lead that isnt causing a problem anyway.

All the lads with huge power VAG cars convert their's back the other way normally

 

One of my friends Grant Parker with the 1000 bhp Mk1 golf has actually converted his 5cyl engine to coil on plug because it is better, (dyno proven).

Virtually all the WRC boys use COP and most high performance bikes now use it.

Why? Because it's not as good as the old plug lead set up



I'm trying to sell something here, not have a debate about it.

 

being fair,, this is the genral Discussion.room,,,,, and i agree with chip,,, as i wrote a good few lposts up

what do drag car use? im sure thay want the most spark energy off off the car types talked about

 

I remember this Good luck Nick

All i know it will be sweet...........

 

Spark plugs wires are going away for the same reason that distributors went away.

Vehicle manufacturers want to improve ignition performance and reliability.

Plug wires are an assembly line nuisance, and are often the weak link in today’s distributor less ignition systems. The plug wires must carry anywhere from 5,000 up to 40,000 or more volts to fire the plugs.

This requires heavy insulation plus the ability to suppress electromagnetic interference (EMI). The wires must also be coated with a tough outer jacket to withstand high temperatures in the engine compartment and chemical attack.

As reliable as today’s plug wires are, there is always the potential for trouble. Even the toughest insulation can burn if a wire rubs up against a hot exhaust manifold. The connection inside the spark plug boot between the wire and plug terminal can also be damaged if someone jerks on the wire to remove the boot when changing sparkplugs.

Plug wires can also radiate magnetic fields that may affect nearby sensor wires or other electronic circuits.

Attaching the ignition coils directly to the spark plugs eliminates the need for separate high voltage wires along with their potential for trouble.

Eliminating the individual plug wires also eliminates the need for wire looms and heat shields. That’s why coil-on-plug ignition systems are being used on a growing number of race engines.

Benefits include:

• Directly mounted to spark plug and includes a robust electrical connection to the plug.
• Greater spark energy may allow increase in plug gap for better burn.
• Increased recharge time due to 4 coils.
• Laminations encapsulated in epoxy for environmental protection and increased safety.
• Reduced weight and under bonnet complexity.
• Improved combustion quality and reduced electrical draw.
• losing one will affect engine performance, but you can still drive

 

i was only going to do it to be different, but didn't get the time to before breaking it.

i don't see why it couldn't work and be reliable on a yb. just because it doesn't on some vag cars that have a transverse mounted engine in a relatively small engine bay doesn't mean it wouldn't work on a yb in a sierra. all depends on coil spec, whether the amp is built in and vulnerable, design of cam cover etc.

management is not normally a problem. they can eaiily be run in wasted spark mode by a conversion as offered by Motorsport Developments, or my RP Lab L8 would have done it.

 

A seperate coil pack, fired by a CD system gives the most spark energy. I will actually be testing some individual setups in the lab soon.

 

It will be interesting to see the results
