Thats because the juices were flowing so well, extra spark was the last thing on my mind

rotarenvy

msd claims these deliver multiple sparks; has the multi-spark got any problems on the rotary engine firing pattern?

You don't need to cut your OEM coil connectors. All you have to do (until BHR releases the customize connectors) is to splice from the MSD LS2 coil wires that you are going to make or purchase to just after the OEM coil connector wire with one of this per wire. I will post pictures later this evening.

i personally would not risk my engine on those types on splice connectors... i've had way too many problems with the damn things on simpe lighting circuits and them loosening up over time and having flaky connections.

Sorry, I'm not a big fan of Vampire Clips. They have a tendancy to cut wires and they offer no protection from moisture and corrosion. Just my thoughts.

Nope.

To the contrary, per MSD literature “These coils produce up to three times the spark energy of the stock coils plus they deliver multiple sparks to help keep the engine clean at an idle.” That also equates to a crisp acceleration, better gas mileage and no misfires at high rpm.

This is just a temporary solution until BHR’s connectors. I order to keep them from loosening all you have to do is to wrap a small zip tite around the closed splice connector.

You can also buy shrinking tube and slip it over the connectors. The shrinking tube can be cutout later on, take the connectors off and use the BHR connectors.

Meh, I can't see a reason to ever to back to stock coils. I'm just going to cut them off and if I should need anything major done to the car I can just recut the new ones. Not really that big of a deal.

If you are going to make your own D581 connectors follow this easy steps:

1. Cut desired length of wire and slip the little yellow rubber seal about an inch back from wire end. See yellow wire with connector provided by the connector vendor as an example.
2. Strip about 1/8 inch of insulation from end of wire.
3. Crimp wire to connector and solder tip (optional but recommended for connectivity assurance).
4. Slip yellow rubber seal forward and crimp to connector.
5. Cut connector away and slip into the black D581 block main connector. Make sure that it goes the right way and it will snap in place (all the way in).

I recommend not doing this assembly in a hurry.

You can make one of this for the four MSD LS2 coil ground wires. I like to solder the end of the wires after crimping just for assurance but it is optional.

Thanks Juan.

Does anybody still want to split the cost of 8?

morkusyambo

That is the best price i've seen from a vendor. Everywhere else I checked is @50-75 bucks more.

staticlag

Juan, is that 16 gauge wire going into the connectors?

Grouch

Yes, I saw that good price posted earlier, and was wondering if staticlag was going to go with those. I was hoping we could split it!

Yes, be very careful when you insert each individual wire/connector inside the plastic holder, it is a tight fit. Verify with an ohm meter that they are not touching inside the plastic holder afterward. I already messed up two connectors and found out the hard way last Friday while attempting to do an install on another RX8. I ordered two additional connectors and will reinstall this weekend.

I already logged over 700 miles on my car with no issues whatsoever.

morkusyambo

By plastic holder, do you mean one of the 4 D581 plugs that hold 4 wires each??

How would they be able to touch once inside?

marsredr100

Too much brutal force from my part. Two connectors scraped and made it thru the plastic holder separation and shorted against the next to wire.

Size of MSD coil

iTrader: (25)

yeah, they're a lot bigger than the factory coils

If I get a custom Magnecor 10mm race wire set rigged up for these, would anyone be interested?

Specs

1cm wires.
heat resistance=
700 degrees continuous
1200 intermittant

Cable/design noise supression capacity 80,000 Volts

Conductive Capacity 80,000 Volts, 200 winds per inch

Magnecors are designed to transmit the full charge while adequately shielding it from disrupting the other electronics in the engine bay.

I know you're talking about something slightly diifferent, but you might want to talk this over with Juan, he just posted this over in the SC thread.

I read that, but the fact is that this engine and ECU are pretty sensitive, the close proximity of the wires and the coils, and the super high voltage of the new coils all leave me pretty shaky about using a "low resistance" wire. When it would be too easy for a spark to jump wires at 9K, maybe it might jump just to the block, maybe it might jump to the next wire and detonate, maybe it might interfere with the trigger signal and trigger the next coil.

I chose the magnecors because they are IMHO the best at shielding, I'm not taking chances with my engine over maybe 5 hp.

If I wanted a super low resistance wire I would use a solid race only wire.


Those low resistance wires may work well for a distributer type engine, but with the coil on plug design with a trigger voltage of only 3V for the coils, I would rather have my 45,000 volt spark charge well controlled.
