New coil, Mallory Promaster

Featured Replies

I got this in the mail today.

Mallory Promaster

It cost me $36AUD inc postage off of eBay.

 

Will i need the risistor form the old coil still? I'll get some pics of it in the car tomorrow.

Its huge!

 

What do ya think? I hope it helps with some of my miss firing I get when I floor it. I'm also getting some 10mm spark plug leads soon (within the next week) Then I'll think about what spark plugs to get.. Cheap $2 ones, or Iridiums for $19 each.

Cool, Use the resistor. I got a Accel Super coil off ebay for my Brat, $14.53 sent to my door. That's a 20oz. Rootbeer bottle next to it. Now I'm looking for a CD ignition box to add to the mix.

what's the advantage of a coil like these?
More spark energy and pretty much indestructable with a stock ignition or when adding a higher output CD ignition.

whats CD ignition?

 

A good coil is definatly something I need to look into. ANd where are you buying 10mm spark plug wires? Wouldnt mind some of those either.

There it is in the car.

I'm using the risistor for now, I'm looking into if I need it or not.

 

I'm getting my 10mm leads from a local place called HarborParts. The problem for you there is this place is in South Austraila... When I get them I'll post the brand name, you might be able to find them in the US then.

I was going to get 9mm leads, cos a mate got them and said they gave him more lowend power. But 10mm sounds ok. :-D

 

EDIT: Sorry about the dodgy pictures. There taken by my PDA camera, cos my bro took his "really nice" camera to the V8 Supercar race we have here in Aus, and then the battery was flat this morning :( Hope these pics will satisfy you.

So how's it run?

I have toyed with the idea of making a direct ignition system for the car, it would not be hard to make a logic board and use a dummy cam-rotor with LEDs and photoeyes - and it would eliminate the high-tension ignition wires altogether. It would also be virtually maitnence-free.

 

I have not had time/$ to persue it though.

 

My current ignition system is crap, in fact I am embarassed to say what is on it right now :-\

 

That is my next point of work

I reckon it maybe made 5% difference... hard to tell, might work better if it doesn't need that risistor.

 

It also doesn't help running out of fuel 2 mins from home!

 

More on it tomorrow, when I get back online.

After more research it depends on what Dis. you are running. If the ignition module is inside the Dis. it appears you don't need the extra resisitor. If your running points or some of the early electronic ignitions with the module mouted by the coil, you need it.
Try opening the spark plug gap.

I run .045 with an Accel SuperStock coil.

Makes a *big* difference.

True, thats one of the reasons to run a bigger coil.

lol.. Mallory told me it needed the risistor! I might take the risistor off and let the motor run for a while while holding the coil, make sure it doesn't get to hot. Then I'll deside what to do.

I'll give the gap a go.. Then when I get my wires I might look into some new plugs.

Thanks Carven and every one else!

If the coil manufacturer says to use the resistor, keep it in there. You could be risking damage and a voided warranty.

Get the new plugs 1st.

Subaru's seem to prefer NGKs, other brands don't last.

I think the platinums are worth the price, but forget about the multi-electrode plugs. Only one electrode will fire per cycle, definitely a waste of bux.

Anyone think the Iridium's are good? I know a guy with bosch iridiums in his 98' RX. He says they are great, and they are also suposto go for much much longer, + more power. Any thoughts?

I dunno about the iridiums, but I know bosch platniums run too hot. I'm changing mine to a colder plug here this week.

Thought I should post this, as it is the answer I've been looking for. I searched on google Mallory Promaster Resistor. It came up with this one a few lines down http://go.mrgasket.com/pdf/ProVoltCoil.pdf and this http://go.mrgasket.com/pdf/28720_29440_29625_29450.pdf

They say with the #28720 ProMaster you need a ballast resistor only one that doesn't is #29450 and and newer. Soo it looks like I've done it the right way after all. Unless the resistor's have difference resistence. I'll be looking itto that next.

The Mallory Ballast Resistor #700 (the one for the ProMaster #28720) is a 1.5Ohm resistor. The one in my brumby/brat is a 1.4Ohm. So it would probably work a slight bit better with the Mallory resistor. But mine should do. Well, that's it!
