I’m fully aware of how a coil functions having been using them in one form or another for over 35 years. In that time I have seen a lot of products come and go that were trumpeted as the answer to a maidens prayer.
It just seems to me that the equivalent cycle for a single coil of 3500 is extremely low for a coil to start to give problems. That is why I am cynical. Generally most devices have a fair margin beyond their rated specifications before they give any problems.
There are other reasons why you might want to use a single coil per plug…
bye the bye - when are you going to be honest and front up all that you know about the origin and give due credit for all the K crank counterweighting tests - and introductions to competant dynamic balancing.! It really is about time you were honest Bernard!
Yet another potentially interesting and informative thread for people ruined by you. What has this got to do with spark plugs?
As I said on the last thread that ended up in Muppet Show, stick to the facts, don’t abuse people and the threads work, the information comes out and you get your side of things over for reasoned debate, but you just cant resist can you. I really do think it’s time for you to be removed from these forums.
So come on Mr Admin, make a decision.
A potentially interesting thread ruined by abuse from me?
dva is about with his childish posts, avoiding any kind of discourse, and throwing the word liar about.
I have not abused Bernard - simply asked him in the face of all this abuse aimed at me - to tell the whole story as he knows it
and you call me abusive
what planet are you on?
I’m on planet Earth, which one are you on?
Simon, it’s quite simple, stick to the facts in the thread, at no time did anyone mention balancing, so why bring it up other than to try and stir things up.
You have to admit that to make a 8bhp improvement from a spark-plug gap, which is what your original post claimed was bound to cause a reaction. All Bernard then did was suggest you check your results. It’s then simple to answer with the facts which you did, but then felt the need to have a pop about balancing which was nothing more than stirring.
I’d be interested to see it too, if there is a problem with the VHPD coil, since I haven’t seen any evidence so far.
A twin coil system has twice the charge time of a single coil for any given RPM.
dva makes great play trying to claim credit for work I was responsible for -initiating, and steeing through counterweight analysis and introducing him to competant dynamicbalancing
I have claimed no credit whatsoever, nor have I tried to, you are just making it up as you go along. This is a thread about plugs , try to stick to topic. Everybody is pretty fed up with the constant repitition and obsessive flogging away at a long dead horse. Take it up with Steve at VF… and keep your petty disputes off this forum, it seriously devalues it for everyone.
RC6YCCs are set at 0.9mm [0.035in] from factory - thats ok with an indifferent ignition - ie old and standard coil.
I set them at 1mm, and there are significant horsepower gains to be had at that gap - 8bhp - but only if the rest of the ignition system is up to it.
simon
If you think you are gaining 8 BHP just from changing the plug gap then I think you need check the results. Assuming your ignition system is up to the job to start with, the spark just lights the fire. It doesn’t matter how how big a spark you use, the end result is the same.
Bernard
Great discussion here guys, however we are now talking about different plugs!!!
The Champion RC6 6YC is readily available for under � 2.00, but this is NOT the Champion RC6 6YCC (ie: the additional ‘C’… whatever that means)!!!
I cannot find this plug anywhere… it is the one that is listed in the VHPD tech specs… ANY ideas where I can get this please, ie: the Champion RC6 6YCC!!!
R - resistor type for wasted spark type systems
C - ‘C’ type shell design 14mm 3/4 reach 5/8 hex
6 - heat range
Y - Firing end design, standard projected core nose
CC - double copper
The terms RC6 6YC, RCY 6CC and RC6 6YCC are not valid champion codes…
Dave
Many thanks Dave!
That has ALMOST solved this question…
Page 82 in ‘Technical Data’ of the ‘Exige manual’ does list the plug as being the Champion RC6 6YCC [color:“blue”] [/color] which is at odds with your ‘codes’ as above!
Just want to get the very best out of the VHPD unit… put the Magnecor leads on last weekend… need to get as much ‘bang’ as possible! hence the original question!

The manual is wrong, Dave is right - its a typo by Lotus
If you want the best bang - cheaply a Ford duratec/Focus/Mondeo twin spark coil is a big improvement over the Vauxhall, not the perfect solution but an easy one for 15 quid new [ebay] you just need to get leads made up specially - and there are better than magnrecor - remember though leads deteriorate so replace them every 12 months
Simon,
Have you done back to back empirical test with this coil against the OE coil?. I have used the Ford coil a number of times simply because it is more available.
Simon Thornley’s 286BHP engine uses a single coil with leads that our by his admission 6 years old with RC6 YCCs set at .035 and it hasn’t missed a beat. It would be nice to think he has another 8BHP to come and maybe some more by allowing the engine to peak.
I dont really see the relevance of your other comments but suspect you may be setting the scene in advance for some rebuttals / denials.
Good, he should be, considering it’s mostly OE parts
This is a thread about sparkplugs yet you still cannot resist spouting already disproven nonsense played out time and time again.
The thought that his engine is mostly OE parts is just so laughable I’m surprised you would even go to the bother of typing it out, I’m sure right now Simon is laughing himself silly.
Let’s try to keep it on topic all we’ll all be singing the muppet chorus again…
www.carsparkplugs.co.uk and other websites have a plug equivalence chart which will allow you determine the equivalent NGK, Bosch and Denso plugs for any Champion plug or vice versa.
