My Magnacore 10mm spark plug wires got chewed. Is it OK to run OEM spark plug wires around 500whp? Ignition setup is HKS Twin Power w/ NGK 10 range spark plugs, running water injection @ 20+ psi so ignition will need to be beefy.

 

my setup started to break up with stock wires at 440whp.

HKS Twin Power, platium 9's, @ 16 psi, newish coils, stock wires...changed wire to magnacore 10.5mm and im good to go.
so sense your hitting higher then me i'm gonna bet stockers wont hold.

at 500 id advise against the stock wires.


but if you want to try/experiment i have some stock wires i can send you for free. pay the shipping fees of coarse and ill ship them to you. just for kicks

 

Thanks for the offer, but I already have the stock wires. Will see if stock wires will work first. Anyone else have experience that can chime in? Thanks.

 

NGK Power Cables will do the job, if you can find them. Unfortunately they've been discontinued. At those power levels, I'd look into something other than stock wires. Another set of Magnecores may be in your future

 

I would not use the stock wires at that power/boost level, go with the Magnecor 10mm Plug Wires 93+ RX-7

 

MSD had a decent wire a while back for the fd. Not sure if they are still around. The NGK power cables were awesome but unfortunately discontinued. I've been thinking of making my own wires. The problem with most aftermarket wires is the boots don't seem to fit our coils properly. This isn't an issue when running aftermarket coils like the AEM marine coils, but a lot of guys are still on the stock setup.

 

Anyone running Magnecor wires with stock coils pushing 500 + hp ?

 

Very unlikely without a HKS Twinpower.

 

Depends on the pugs your using.
If you run the EGV series plugs as they are a non resistor plug you can get away with no hks high power and STOCK plug wires at 500whp levels. Ive done this for many years with 800cc water injection and boost levels anywhere from 18- 30psi depending on what you have the boost controller set at.
Some say that the EGV plugs cause ignition interference but I have never experienced this in all my years of using them.
You can definitely benefit from better plug wires over the stock ones in any instance.
If your running a high power and non resistor plugs then its advised that you run aftermarket wires to maximize your setup.

 

I would be grateful if someone please explain ignition breakup and the symptoms that suggest one should upgraded ignition. Besides low rpm missing. I've googled it, but never found a satisfactory answer- just "buy this". From what I understand the stock ignition system is high output.

 

Ignition breakup coincides with spark blow out. This suggests that the ignition has not enough power to make the spark. You can shorten the gap yes but that will most likely cause you to loose power.
Also something that I see customers confuse is the term hotter spark and actual spark plug temp. This is something that lots of people get confused upon.

 

I should be very close with my new setup. Made 454whp @ 23psi with no ignition breakup. Spraying around 700cc of 50/50.
I purchased a new leading coil beforehand. I also highly recommend running a quality plug. NGK Race plug 10's all around. Banzai Racing sells them.

As a side note, I plan to contact Magnacore to see if they produce their plugs in black. Fire red things are throwing my scheme off...

 

^ I quoted the wrong person on my last post. It was intended for the "500hp on stock coils". I am running a Twin Power, Magnacore plugs, new leading OEM coil, and NGK Race plugs. No issues.

 

Don't the race plugs take forever to warm up ? And don't last as long ?

 

I have put around 2k miles on mine. Never heard of a "warm up" issue but selecting the proper heat range for your application is important. Colder ranged plugs can cause issues with idle and low end driving if not selected properly.

The NGK race plugs are pretty much top of the line. When pushing any ignition system every aspect must be on par.

They sit at around $30 per plug now. Not cheap, but then again, nothing about a 500whp rotary is....

 

Thanks, google provided a little more info on spark blow out. From what I understand at conditions of higher air flow the spark gets blown out?

I've experienced fuel cut before (lots of hard bucking) from about 2600 - i think to 5500 rpm, beyond that no hesitation to redline. (Didn't let the car relearn the idle.)

When ignition break up (spark blow out) happens, does the resistance during acceleration feel lighter than fuel cut?

 

Water injection can also cause blowout as well.
And as for race plugs warming up. Unless your running a really really cold plug you wont have a "warmup" time. Ive ran 11.5 greddy/ngk race plugs with no cold issues as well as no idle issues

 

A true testament to these plugs. They are quite impressive! I'm running 10's on all 4 with zero issues.

 

We've done our own independent testing to settle on a wire of choice for SBG's setups, and we've found that the the 8.5mm MSD SuperConductor wire vastly outperforms the Magnecor wire (either 8.5 OR 10mm). From a performance perspective Ω (resistance) is what counts, and taking everything into consideration the MSD SuperConductor is hands down the best wire available, period. Don't take my word for it... search around for tests comparing various race wires and you'll come to the same conclusion we did.

Yup, that's right... 1,267 ohms vs 31 ohms






Tested all major spark plug wires. My results...
From the above link:
“Granatelli 8mm Steel Solid Core Cable - 0.1 ohms
MSD 8.5mm Super Conductor - 71.6 ohms
Accel 8.8 300+ Ferro-Spiral Race Wire - 166.1 ohms
Jacobs Electronics EnergyCore 8.5mm - 178.3 oms
Taylor Spiro Pro 8mm Silicone - 301 ohms
Mallory Pro Sidewinder 8mm Silicone Suppression Wire - 313 ohms
Moroso Blue Maz Spiral Core 8mm - 661 ohms
Magnecor KV85 Competiton 8.5mm - 2053 ohms“

We found similar results when testing the 10mm Magnecor wire vs the MSD wire. Just for the record, we have no affiliation with MSD other than the fact that we like their wire best. We prefer the crimps and boots from Magnecor to the MSD counterparts, so we actually build a hybrid setup using MSD wire and Magnecor boots and connectors. We've found this combo to be the absolute best of both worlds. The MSD SuperConductor wire uses a proprietary helical winding around a feromagnetoc core that has around 40-50 ohms of resistance per foot--but with an EMI/RFI suppression equal to a 1,500 ohm wire! We've done our homework, this is vastly better wire than anything Magnecor offers... down to the double walled silicone insulator vs a thick single wall on the Magnecor. Don't get us wrong, the Magnecor wire isn't bad per-se... the MSD wire is just MUCH better. We've been producing these for our own cars, and they're the best wires money can buy. We don't currently sell these, this is just an honest recommendation for anyone looking to get maximum power from their coils to their plugs... remember resistance generates heat so wire life should be extended as well with lower resistance wires. Food for thought.

^ If I can get a set in all black I'm sold...

 

We can get boots in dark gray but these particular red ones are the highest quality ones we've found to date. You'll never see them anyway but the story of the hour is crazy crazy low resistance

 

Ever test out these ebay wires ?

93 97 Mazda RX7 FD3S 10mm Racing Spark Plug Wires Red | eBay


Or how about the $150 Nology wires ?

http://www.ebay.com/itm/NOLOGY-HOTWI...723b65&vxp=mtr

 

One of my Magnecor 10mm wires developed a internal break around 20K miles which caused the car to breakup at high RPM. For the price I paid for those wires I would expect more then 20K miles worth of use. I went back to the stock NGK wires and never had a problem.

 

I was gonna get a set of red magnecors for when I fire up the FD engine but I'd like to get a set of AEM independent coil packs soon, then I'd have to get MSD EFI wires so I think I will try the ebay red wires for the time being and post up their resistance..

 

Yup, that's right... 1,267 ohms vs 31 ohms

great information!
thanks a lot!
