Sure try British wiring at www.britishwiring.com/ Rhode Island Wiring at www.riwire.com/ And Restoration Supply Company at http://restorationstuff.com/ All sell vintage plug wire in a variety of color combinations Rick Storms

Spark Plug Wires

Post by Steve S » Wed Sep 16, 2015 11:19 am

What is the group's opinion on the best plug wires and connectors to use on the TC? I'm running the stock type setup (Packard stranded wires with Lucas connectors) which has been just fine up to now, but with a few performance enhancements I'd like to try something different to gauge any difference in high-speed running. Moss lists their standard wire (basically what I'm running now) and Bumblebee wire which doesn't list any specs but I suspect it's the same non-shielded copper wire. - Steve Simmons, TC8975

I'd wager the choice of wires makes enough performance difference between two otherwise equivalent well-prepped racing TCs driven by expert racing drivers to gain half a car length over the course of a race on a twisty track like the Glen.   key words, "just fine up to now."  exu7617 is a road car at 1380 cc, balanced/blueprinted engine, high lift/moderate duration cam timed well, prepped carbs, and a bone stock ignition system (including wires).  Seems to run as well as any street TC.   Maybe I could wring a little more out with an idealized diz/coil/wires/plugs, but at what cost to gain what?  Phil  [i]Come to kindly terms with your ass, for it beareth you ....John Muir[/i] [b]From:[/b] "Steve S mail@mgnuts.com [mg-tabc]" mg-tabc-noreply@yahoogroups.com> [b]To:[/b] MG tabcgroups MG-tabc@yahoogroups.com> [b]Sent:[/b] Wednesday, September 16, 2015 2:19 PM [b]Subject:[/b] [mg-tabc] Spark Plug Wires   What is the group's opinion on the best plug wires and connectors to use on the TC?

Re: Spark Plug Wires

I follow the same line of thought. But with a strange issue I've been trying to diagnose, and old wires and connectors in the car, I figure I have to buy something anyway so why not the best wires I can get? And if I notice no improvement then next time I won't bother. 9.1:1 compression, high top pistons, re-curved distributor, Runbaken oil coil, roller cam, 1.5" carbs (as an experiment, normally 1.25") and an alloy valve cover that almost certainly adds 5HP. ;) - Steve Simmons, TC8975 On 9/16/2015 11:40 AM, phil smith wrote:
I'd wager the choice of wires makes enough performance difference between two otherwise equivalent well-prepped racing TCs driven by expert racing drivers to gain half a car length over the course of a race on a twisty track like the Glen. key words, "just fine up to now." exu7617 is a road car at 1380 cc, balanced/blueprinted engine, high lift/moderate duration cam timed well, prepped carbs, and a bone stock ignition system (including wires). Seems to run as well as any street TC. Maybe I could wring a little more out with an idealized diz/coil/wires/plugs, but at what cost to gain what?

I'm running the stock type setup (Packard stranded wires with Lucas connectors) which has been just fine up to now, but with a few performance enhancements I'd like to try something different to gauge any difference in high-speed running. Moss lists their standard wire (basically what I'm running now) and Bumblebee wire which doesn't list any specs but I suspect it's the same non-shielded copper wire. - Steve Simmons, TC8975

For a street car the bumble bee wires for the proper look.  For a race TC I used Moroso or Summit solid core wires.  If you buy a V8 universal set, will have enough wires to make 2 sets.   Ed   In a message dated 9/16/2015 2:48:09 P.M. Eastern Daylight Time, mg-tabc-noreply@yahoogroups.com writes:

Somewhat different story if you've got to replace them anyway....the incremental cost will be small and it would be a good informal albeit uncontrolled and rather subjective experiment.  And if MGs didn't want us to tinker with our cars, they would have welded the bonnets shut.  That allow cover alone is worth more than 5 hp.......I've stuck with the pressed metal cover, being afraid of both a whiplash injury on acceleration (lack of head restraints on the TC seating) and insufficient brakes to haul me down from the quickly-reached supersonic velocities.  Phil p.s.  Are you happy with the larger carbs?   I once tried 1 3/4 " carbs on my rally car (MGBGT) and found marginal gain at top but a real loss of palpable torque....I went back to the standard MGB 1 1/2" SUs, with some prudent prep (smoothing off rough edges etc....  but not monkeying with the bridge).   [i]Come to kindly terms with your ass, for it beareth you ....John Muir[/i] [b]From:[/b] "Steve S mail@mgnuts.com [mg-tabc]" mg-tabc-noreply@yahoogroups.com> [b]To:[/b] MG tabcgroups MG-tabc@yahoogroups.com> [b]Sent:[/b] Wednesday, September 16, 2015 2:48 PM [b]Subject:[/b] Re: [mg-tabc] Spark Plug Wires   I follow the same line of thought.  But with a strange issue I've been trying to diagnose, and old wires and connectors in the car, I figure I have to buy something anyway so why not the best wires I can get?  And if I notice no improvement then next time I won't bother. 9.1:1 compression, high top pistons, re-curved distributor, Runbaken oil coil, roller cam, 1.5" carbs (as an experiment, normally 1.25") and an alloy valve cover that almost certainly adds 5HP.  ;) - Steve Simmons, TC8975 On 9/16/2015 11:40 AM, phil smith wrote:

Re: Spark Plug Wires

Keeping in mind my engine has been slightly built up, the 1.5" carbs do seem to have a bit more power overall. I think it may have been slightly under-carbureted before. My 1.25" carbs are being rebuilt, and when they are done I plan to reinstall and tune them from scratch so I'll have an A-B-A comparison. I don't believe that the 1.5" carbs would have made a difference when the engine was closer to stock. - Steve Simmons, TC8975 On 9/16/2015 11:59 AM, phil smith wrote:
Somewhat different story if you've got to replace them anyway....the incremental cost will be small and it would be a good informal albeit uncontrolled and rather subjective experiment. And if MGs didn't want us to tinker with our cars, they would have welded the bonnets shut. That allow cover alone is worth more than 5 hp.......I've stuck with the pressed metal cover, being afraid of both a whiplash injury on acceleration (lack of head restraints on the TC seating) and insufficient brakes to haul me down from the quickly-reached supersonic velocities. Phil p.s. Are you happy with the larger carbs? I once tried 1 3/4 " carbs on my rally car (MGBGT) and found marginal gain at top but a real loss of palpable torque....I went back to the standard MGB 1 1/2" SUs, with some prudent prep (smoothing off rough edges etc.... but not monkeying with the bridge).

But with a strange issue I've been trying to diagnose, and old wires and connectors in the car, I figure I have to buy something anyway so why not the best wires I can get? And if I notice no improvement then next time I won't bother. 9.1:1 compression, high top pistons, re-curved distributor, Runbaken oil coil, roller cam, 1.5" carbs (as an experiment, normally 1.25") and an alloy valve cover that almost certainly adds 5HP. ;) - Steve Simmons, TC8975 On 9/16/2015 11:40 AM, phil smith wrote: I'd wager the choice of wires makes enough performance difference between two otherwise equivalent well-prepped racing TCs driven by expert racing drivers to gain half a car length over the course of a race on a twisty track like the Glen. key words, "just fine up to now." exu7617 is a road car at 1380 cc, balanced/blueprinted engine, high lift/moderate duration cam timed well, prepped carbs, and a bone stock ignition system (including wires). Seems to run as well as any street TC. Maybe I could wring a little more out with an idealized diz/coil/wires/plugs, but at what cost to gain what?

I'm running the stock type setup (Packard stranded wires with Lucas connectors) which has been just fine up to now, but with a few performance enhancements I'd like to try something different to gauge any difference in high-speed running. Moss lists their standard wire (basically what I'm running now) and Bumblebee wire which doesn't list any specs but I suspect it's the same non-shielded copper wire. - Steve Simmons, TC8975

Re: Spark Plug Wires

Steve,

Over the years OEM spark plug wires have been dumbed down considerably as bean counters vetoed traditional copper wire core because of costs & need for heavy shielding required cope with of RFI & EMI interference in modern engines. The replacement wire cores tend to have hundreds of times more ohms (resistance) than traditional copper core wires. To overcome the high ohm/resistance wire, OEM s have gone to versions of amplified ignition systems needed to push enough currant to the plugs overcoming the resistance. These heavily insulted wires, modern wires are heavily shielded, which negatively impacts being able to use low resistance wire. With non amplified XPAG ignitions, the goal should be to use wires with possible lowest resistance, copper wires if they can be found, or better yet silver core wires seen on some aero engines. Copper & silver wires have virtually nil resistance., Today the best wires composite shielded wires are those from MSD which have MOL 50 ohms/ft resistance. This compares to 3k-20k ohms resistance of today s OEM & aftermarket wires. As our vintage cars do not have

RFI (radio frequency interference) issues -unless an aftermarket audio system has been installed, or EMI (electro- magnetic interference) issues. Using today s high resistance aftermarket wiring w/o an ignition amplifier will lead to poorer ignition performance, especially as higher cylinder pressures are reached.

What is the group's opinion on the best plug wires and connectors to use on the TC? I'm running the stock type setup (Packard stranded wires with Lucas connectors) which has been just fine up to now, but with a few performance enhancements I'd like to try something different to gauge any difference in high-speed running. Moss lists their standard wire (basically what I'm running now) and Bumblebee wire which doesn't list any specs but I suspect it's the same non-shielded copper wire. - Steve Simmons, TC8975
