Lucas Sport Coil

I was looking through my new Moss MGB catalog today and I noticed the Lucas Sport Coils. The ad says it puts out 40,000 volts. Will this work on my 77 "B"? Or I suppose the real question is, is there enough advantage over my stock coil to justify the cost? /ubbthreads/images/graemlins/confused.gif
 
If your current coil is working properly then it isn't worth the "upgrade". If you need a coil anyway, the extra voltage will give a stronger spark and allow you to open up the plug gaps a little. You may or may not notice a difference between a stock coil in good order and a sport coil.
 
Steve is spot on. /ubbthreads/images/graemlins/iagree.gif as always /ubbthreads/images/graemlins/savewave.gif

Then you probably have a worn engine.---Keoke

They do look cool, though...

Thats why I put one on my A....I didn't notice much difference, although I don't really drive it enough to notice anything.
 
Old coil seems to be working correctly. I was just curious if there might be some advantage to be gained by installing a hotter coil like the Lucas Sport. /ubbthreads/images/graemlins/square.gif
 
There is a cheap way to dress up your coil. I just put a chrome cover over mine from Summit Racing, to the tune of $3.95. You can see a picture on my Cardomain site (link in signature).
 
Whooo, did not know something like that exhisted.
 
When you put it on, keep in mind that you will have to actually wrap the coil cover around on itself just a bit to fit our smaller coils. You will also have to bend the legs on the bracket so that they are straight, as they will start to bend towards each other as you tighten the set screw. Use the shorter, thicker screw.

Here is the part #:

Mind you, I live about an hour away from the Tallmadge retail store, so if you order it, handling will probably cost more than the part. When I drove down I bought an oil filter cover as well that I plan on fitting an MG grill badge to. The cost of both of them was just over $10 with tax!
 
You're kidding, right?

That belongs on the badge bar where everyone can see it! /ubbthreads/images/graemlins/thumbsup.gif
 
Abso-freakin'-lootly!!!
 
You may need to plead to Basil as the BCF store is offline.

Groveling is demeaning, but p'raps helpful in this circumstance. /ubbthreads/images/graemlins/wink.gif
 
kyreb, absolutely minimal advantage under stock conditions. The only real time people 'notice' (=placebo?) use of a fatter spark/larger gap is on starting, esp. when cold, where a larger spark may help ignite fuel a little better. Having said that, a well setup stock ignition, carburettor and choke do just fine.

Fatter spark becomes of use with larger gaps when trying to ignite altered fuel mixtures such as occur with altered carburettion (needles, intakes, porting of head etc.).

The other thing to consider is that the increased voltage will have to go somewhere, leading to increased arcing and sparking across worn/tired rotors and dizzy caps, leading to reduced item life and reliability.

I won't deny however, that the colour is really nice!
 
"worn/tired rotors and dizzy caps"

Wait, I thought we were supose to change them durring tuneups. Like 6 thousand miles or annually.

Course I think some of these cars we get hold of never had a tune up.
 
What color was the original coil on the early "B"s? Black or bare metal? Oh yea, I put a sport coil on my car and it made no differance in it's performance. Looks nice, but I wouldn't do it again. Not worth the money. /ubbthreads/images/graemlins/rolleyes.gif PJ
 
Dunno, Paul...the two in the Gees above are bare metal, but I'm not sure if they're original (they're certainly stock, AFAIK).
