Good Thread,does anyone know if it is possible to use a Lucas sports coil on a standard Luminition set up?

Mark

If you get a Lucas sports coil make sure its suitable for a 8 cylinder. From experience a normal one made for 4 cylinders don't cut when you welly it.

I have a Bosch red if they still use the colour to distinguish coil type.

Always meant to try a bigger plug gap, will give it a go after reading this thread.

The Lucas DLB110 is the one to go for and it is also used extensively in Minis

I would question if something meant for a 4 cylinder Mini is suitable for a 8 cylinder.

To my simple brain,a 4 cylinderwould need tobe doing12000 revsto match number of sparks per rev required by 8 cylinder at 6000 revs.Not many Miniswould be capable of thatoram I talkinga load of crap:?

I was thinking on those lines too, so you're not alone.

The coil that you have fitted to your stag will have multiple applications.
If you do a google search you will be surprised.
They are fitted to, as I said, many minis, metros, TVR's and skodas etc etc

Are the red ones faster Russ?

Can someone tell me what the difference is between a lucas coil DLB 102 a 105 and a 110. Also when it says 3.00 ohms, 1.5 ohms etc.

Cheers.

I am sure there are more knowledgeable guys on here but
the DLB102 is the standard stag 6v coil to be used with a ballast resistor and
the DLB110 is the 'sports' version of the above with a higher output which will enable you to widen the plug gap
the DLB105 is a normal 12volt coil

Lucas Sports Coil 6Volt for use with ballast converter situations or ballast wire situations.
These sports coils when used with Sports Electronic ignition, like for example Lumenition Performance Magnetic as opposed to standard Lumenition Optronic systems, can be asked to produce higher high tension voltage than standard.
They will produce up to 40,000 Volts.
To achieve this the spark plug gap is opened to 40K

This can improve performance

Normal coil output is 25,000 volts.

The ignition leads sold on this site can handle up to 30,000 Volts. If you wish to use the full 40,000 then it is wiser to invest in some ignition leads suitable for purpose.

We are also advised that it is likely the Rotor Arm and Distributor cap will need replacing more frequently when used with extra wide Spark plug gaps.

NOTE
Why a 6 volt coil in a 12 volt car?
With the points closed, current will flow as follows: battery to ign switch to ballast resistor to coil to points and finally to ground.
With an assumed charging voltage of 14 volts at the battery, we can measure voltage drops of about 8 volts across the ballast and 6 volts across the coil. THIS MAKES THE COIL OPERATE ON 6 VOLTS WHICH INDICATES THAT IT IS A SIX-VOLT COIL.

Yes Adie, but the red nosed one had real problems with leakage so they fitted them with a protective sheath......

Russ Hi,Sorry about this but still feel some clarification is reqd on this v interesting thread,some suppliers say that you can fry the standard optronic luminition system by using a sports coil,and it should only be used with a Sports Luminition,or their own Megaspark coil (retails at about £40).

I have read all of the thread and your point about doing 14,000k on good quality OEM HT equipment.

I know this comes down to personal choice also,but is it safe to run A Lucas DB 110 on the standard luminition?.

Think I just need to know if you have standard Lumi set up and not the Sports Luminition ignition.

I hope Ive explained that ok.Cos I really would like to go with this mod and open up the plug gaps.

Apologise again for questions,I know it can be tyring being a Guru(joke) .

Thanks Mark

Further to Marks second question does the ballast resistor need to be by-passed.

Hi Mate if you are fitting a DLB110 it is a direct replacement for what you are currently using - no need to change anything (except widening the plug gap)

Completely safe Mark, although you should have the power module mounted in a cooler part of the engine bay if you are worried.

Have you read what Peter Howells says on his website (ldparts) alongside the Lucas DLB110?

BP5E at 35thou on a Lucas sports coil and Lumenition

Hi Russ

if this Lucas Sport Coil is the type DLB 110 (the sports version of the standard 6 Volt Stag coil DLB 102 as Darren wrote) could you or any other member submit a Lucas part number for the above mentioned coil as the Sport Coil is offered in the internet in 6 V and 12 V. I under stood it should be the 6 V type. Lucas parts are difficult toget in Germany w/o a part number.

By the way: the confusion was perfect when I red the first paragraph of www.vtr.org/maintain/ballast.shtml Is that only related to the use of a 12 V Lucas Sport Coil?

Any comment?

Dave,thanks yeh I have read up on this as much as I can inc LD parts,thats whats confusing me...........ie the difference in opinion.
