Hello,

Considering purchasing the digital Mallory Hyfire VI multiple spark unit or the digital Hyfire VIal instead of the MSD digital 6 or the analog MSD 6al with the TFI mallory coil...

The main reason I am adding either is to go with a novi 1000 blower as a spark based rev-limiter as opposed to the factory fuel limiter.

I know that Anderson Ford Motorsport installed the multiple spark on the project car they have been doing in 5.0 mag lately.

Anyone use these products or have any bad experiences with them? They seem to have a lot more bang for the buck compared to the MSD units.

Thanks!
Andrew

PRIESTSGT · 03-03-2007, 10:24 AM

Andrew, you're going to get mixed reviews on both those, but I'll give you my story-
I had 3 Highfire 6's, only one made it to a 3k oil change before going bad and being sent back. I switched to MSD, so far so good.

I'm sure others will have the same story but with the msd failing. Keep in mind too, that the rev limiter in trhat Mallor VI isn't a soft touch. I don't know if it matters but it sure doesn't sound very good if you hit that rev limiter. lol good luck! Oh, and i had constant idle isuues when the Mallory WAS working as well.

hpfiend · 03-03-2007, 12:07 PM

exactly the feedback I was looking for! Thanks! Anyone else?

jstruckman50 · 03-03-2007, 12:50 PM

I have used both the Mallory and MSD. The Mallory worked great then just one day died. The MSD units seem to last longer. Look at all of your Nascars and who they use, it seems they all use MSD boxes.

RED95GTCOUPE · 03-03-2007, 02:27 PM

My Mallory died after a few months, luckily i used their TFI harness so all I had to do was swap connectors to get it running again. Has anyone ever sent one back to get repaired? What usually goes wrong in these ignitions when they die?

'91 GT · 03-03-2007, 04:45 PM

Are you guys referring to the digital Mallory box that has the LED display (that's what I have)? If so after how long did it die? No probs w/mine so far...just curious for future reference

bmcdaniel · 03-03-2007, 05:53 PM

I've been running the HyFire VIA for three or four years now without problem. As mentioned above, you'll get mixed reviews. The MSD unit I had before that only lasted a few months. I made up a shorting plug using a mating connector in case this box goes bad. I just unplug the box, plug in the mating connector, and drive home. The Pertronix module in my distributor allows me to do that.

strker347 · 03-04-2007, 01:20 AM

waht about the Crane Fireball Hi Dig 6??

I have had 2 MSD fail on me. one 6AL and one digital 6 plus.

LOL, they all also have back ups hooked up for when the first MSD fails.

Lamar · 03-04-2007, 06:53 AM

i have used many of both brands and had failures with both,I prefer the mallory digital readout unit simply because of the extra boxes you don't have to buy from msd and no chips to change. Lamar

Ph1ber Opt1k · 03-04-2007, 01:25 PM

I use the mallory digital 6 (pn 685) I choose it over the msd because it has so many features built in, 2 stage limiter, window switch, rpm switch, start retard, boost retard... etc.etc

Yup...their "MSD" boxes fail A LOT! I had a couple MSDs go bad on me so I went w/the Mallory digital box this time...no probs. And the digital LED display makes things much more convenient.

Also like mentioned it has A LOT more features; LED display, digital rev limiter (no dials), built-in adj boost retard, etc)...all for almost $100 cheaper than the MSD dig box. Ignitions aren't completely predictable so it can be hit & miss.

makanik1969 · 03-04-2007, 04:12 PM

I have used many

Msd boxes with many failures, I have switched to the Mallory 6 series boxes with no problems in with them and I have had one in service now for about 3 years. Best change I feel that I have made yet. No added boxes or clutter, no chips, and just as easy to install. I really like the all in one switches on the Mallory boxes.

Dustang83 · 03-04-2007, 06:24 PM

Just by listening to the problems that are had with MSD and Mallory, I would recommend a Crane HI6. I've been running mine for 2 years with no problems whatsoever, except better performance, less plug fouling, and a stronger idle (carbed car). I honestly haven't read of any major issues with the Crane unit.

Roadrunner23t · 03-05-2007, 03:38 AM

I have run an msd 6a for years(with an msd coil)but have used msds in the past and they would stop working because I used a stock coil. Any one else have this problem

nate-roth · 03-05-2007, 10:43 AM

I run the Mallory 685. it's got a ton of fetures for the price and is very user friendly. I did have one die, but Mallory was great and fixed it free of charge, it was about 6mos. old at the time. Personally, I think they all use pretty much the same circuitry and hard parts, so reliability should be about the same. MSD has always had the nickname "Might Suddenly Die" around my ciricle of car bud's, so go with what's right for you.

Quick86 · 03-05-2007, 10:46 AM

I had a Mallory Hyfire on the car when I bought it... Didn't like it much at all... It died after less than a year.. Switched to a MSD 6AL - love it!

bmcdaniel · 03-05-2007, 12:03 PM

It can make a big difference if you mount the box away from heat and moisture.

getsome95 · 03-05-2007, 01:00 PM

i have the mallory IV6 i think it is and i felt the diference,smoother during acceleration,feels a tad peppier,revs quicker.

Matty5k · 03-05-2007, 01:12 PM

I also run the Mallory hyfire VI 685. I bought it because it has the digital display and it has like 9 different modes you can select from. im also running the map sensor with the built in boost retard for the blower. I mounted it inside the car so I can toggle and adjust the boost retard when im driving. I also like it because when you adjust the different values its a digital number rather than the rotary type knob like the old MSD boost retard box I had. I def recommend it.

hpfiend · 03-05-2007, 09:16 PM

So how did you guys run the wires, on any ignition box, from the coil in the engine compartment all the way to under the seat or on the pass side transmission tunnel.

Thanks!
Andrew

Drilled a hole in the passenger-side firewall and used a rubber grommet.

scott88 · 03-05-2007, 10:35 PM

Same here, only on the drivers side. The harness is pretty long for the MSD 6-AL.

Scott

hpfiend · 03-06-2007, 08:54 PM

Did you guys take your 12 volts directly from the battery?

Take a look at the Crane HI6. Not too many people seem to have complaints about them failing. That's what I went with. Have had no problems.
