Ok so did a plug change (to BPR6ES) wanted to ditch extenders and purchased some DEI Titanium heat socks as recommended on here

But......the plug leads (Magnecor blue) are not long enough when you remove extenders and that’s looking at routing options can just about get them on but there right and no option to angle them up away from manifolds

So what leads do you buy that would be long enough ? As if you order for application (Chimaera) they would be what I have and too short ?

Who is running no extenders what leads do you have links would be good so I know they will defo fit !!

Cheers

IMO the after market leads have limited benefit and often suffer more from heat damage. A standard set of Lucas leads provide plenty of length and are very resistant to heat damage. Don't buy Lucas from eBay however, in my experience these are sometimes Chinese copies. Go to TVR Parts and buy Lucas there, Mine have been on for over 4 years and 10k miles without issue. Single 6" socks and no extenders

Id mostly agree, although I bought a fancy set of msd super conductor leads if one of them goes tits up I'd have an issue of where to get a replacement.yank leads do withstand the heat better though.
Id stick to quality standard ones.

I'm a fan of MSD Super Conductors, just buy a universal V8 set then cut and crimp to size, I bought a proper crimping tool from Ali Express for just £12.00 including shipping, it arrived from China in 10 days and is a good quality tool that makes perfect professional quality HT lead crimps.

For additional replacement MSD Super Conductor leads you can buy the distributor/coil pack and plug ends separately and the MSD Super Conductor lead by the meter, however I've found the MSD leads and ends to be extremely durable even on LPG which stresses HT leads much more than when running on petrol.

In my opinion and after testing many brands you'll not find better leads than MSD Super Conductors, not only are they extremely resistant to heat they are also the lowest resistance HT leads available. Despite their low resistance they give no EMI issues whatsoever, I've actually run my TVR on these leads with super powerful MSD EDIS coil packs pushed to 5ms of dwell and non resistor BP6ES plugs fitted for the lowest resistance strongest spark and there are zero EMI issues whatsoever.

Thanks all !

I’d rather buy a set all done as never made them up or indeed have any tools to do this !

Don’t understand why magnecors would not be to length anyway without extenders ?

Is anyone running magnecors without extenders ?

Yes & I know how you feel, I got my Magnecors without extenders from from John Eales, www.johnealesroverv8.co.uk


The only word of warning is the king lead is too long for TVRs so Magnecor made me a shorter one.

Ok I can see that you have angle heads for plugs mine are straight !! But are blue magnecors

It’s as if they are only meant to fit with extenders

Here you go and at this price you could buy 2 sets and keep a set as spares.

I don't think the TVR market understands the magnecore leads- basically you have two things to worry about (apart from heat) - the peak HT the lead can stand, and the lead resistance. Now magnecore do three types of lead- Black ones for classic cars, limited HT capacity and some lead resistance- if you have to use them, these are what you want for a 40 year old ignition system with 1 coil. The Blue are thicker so stand a higher HT, and have a lower core resistance. The down side is the lead is less flexible, and you start to get EMI issues as the leads are less suppressed. Likewise Red are really for race engines running super high HT systems and CR ratios and no worry about stray EMI, but again they are far less flexible and will glitch your ignition primary worse than the blue. I really dont understand why people pay silly money for the wrong leads, but it has to be due to the big mark up the re sellers can make by hoodwinking you into thinking you need them for that "highly tuned V8" that might do 60 BHP per litre on a good day.

For what it's worth, my Griffith 500 came fitted with blue Magnecor leads and I've just fitted socks and removed the extenders in a first effort to eliminate a sporadic misfire. My leads also fitted fine after removing the extenders, and yes they are angled plug connectors.

One point to check is that your HT leads follow the correct route from the distributor and don't wander around. Is it just one or two that are slightly too short?

I have just bought a bunch of Lucas parts including a set of HT leads from LRDirect. Nothing is fitted yet but if you need the leads measuring, let me know.

Thanks

Yes I’m a fan of OEM why as you tend to know they work and fit , but will take upgrade advice on proven tests but.....at a convenience to me I.e can just fit and not have to mess about with making ends which I have no experience in doing or the tools and secondly price I did see how Lucas leads can be £20 and Magnecors £100 ?

I’ve checked routing and even the most direct route puts a strain on the back two plugs and places them on the manifolds no option to lift them up and away and I have straight ends not angled like most seem to show pictures of ?

Checked the original invoice and it’s says Chimaera V8 but are straight ends !

At this point in time due to positive feedback on the Lucas leads and at £20 must be worth fitting these knowing advice has been they have long enough length to fit without extenders !

That’s why I like forum advice as you get real feedback not marketing hype ! No doubt though that the MSD ones have a proven track record just a hassle and expensive !

Even the magnecors would be good working on mine as we speak it’s just can’t remove extenders which is a pain as that’s what I wanted to do and fit the socks not have to buy more leads !!!

On my last Chimaera, I bought Lucas ones designated for a Range Rover, it avoided the TVR 'tax.' Less than £20 delivered. smile

Only the king lead was the wrong length so I bought a single aftermarket one. This lead doesn't get the same huge heat exposure as the plug leads.

I recently bought these 10mm ones as I've melted a couple of mine on the manifolds. Says the silicone is more resistant to heat they could be a load of nonsense but for £25 posted I thought I'd give them a go.

Accel do a ceramic boot which is so much better than any silicon boot.. I had silicon boots with socks..accel 9000 leads were a great replacement.
