Individual coils

I must have too much time on my hands, I have been thinking a bit outside the Rover V8 box, I have been looking at individual coil on plug coils from a suzuki 600gsxr, My ECU can run the coils, I was looking at focus coil packs, but I saw the bike coils and that got me thinking, are there smaller coils than the suzuki/denso coils, advantages disadvantages, Discuss please.
Ian:) :)

I dont personally feel I know a great deal on engines but my take on this would be to go for the wasted spark system as it is less complicated and the cost is much lower, spending the money else where would be more benifical on the engine. If the engine was forced induction then I would probably look into this idea further as its certainly better.
whats the ECU??

whats the ECU??

engine control unit, the brains in the little black box that switches the coils and injectors on a car with modern fuel and ignition systems

shame on me
:rofl: sorry my fault, I should of asked what make of ECU not whats the ECU

EmeraldM3Dk, I had a chat with Karl at Emerald today, He seems to think its a waste of effort, more complicated than a pair of coil packs for no real gain, other than unreliability and having to make a frame to support the coils.
Ian;)

I'm sure Graham said that with tongue in cheek!!

The LS1 and later Chevy's all run coil per plug.

Lots of cars now fit coil-on-plug systems to do away with potentially unreliable HT leads. Vauxhall Omega's were notorious for eating HT leads, and coils cracking up (which are a total female dog to change!) Later models went to coil on plug which are zillions of times better and ultimately reliable.

Penny in the mug!

as a roadside breakdown patrol i can catagorically say that individule coil packs are FAR LESS reliable than going wasted spark coil pack with HT leads

I have been warned against individual coils on both reliability AND performance grounds by some very knowledgeable people.

I am still using them on my V6 but will change to wasted spark at the first sign of any trouble.

The engine came with them so I guess I am just penny pinching, or just like the sound of 'sequential ignition' to go with my 'sequential injection' that I actually need to have a hope in hell of a 350BHP 3 litre V6 make it round the M25 during rush hour without constantly stalling.

The problem with individul coils is that there are some pretty bad ones getting around. The Denso coil comes to mind as it is quite temperature sensitive and will lose considerable spark energy over 90C.

Good ones are the Marelli BAE403 or the Bosch Single P style. Either of these are quite powerful and reliable.

At least if one fails you will lose one cylinder instead of 2!
