They're real results too... I was skeptical at first but folks aren't lying.

How long til your pirep is out. I’m debating installing a dual Eis mags on my eagle.

i agree with surefly cost being a no brainer if you are needing to overhaul a mag anyways. And in addition to all the pluses above my mag is pressurized for when i fly high that the surefly does not require so the surefly offers another layer of security in that if I’m at altitude and the mag starts misfiring because the pressure failed i can shut it down and still get to an airport on the surefly. Also on the other hand if for some reason i lost both alterations and ran down my battery i can still fly to an airport on my one mag. I have experienced zero negatives from adding a surefly and benefited from actual noticeable better starting, lower smoother idling and half a gallon less fuel burn at cruise. I have no regrets and would add it to any other plane in a heartbeat. My neighbor just added sureflys to his baron twin and enjoys over a gallon per hour less fuel burn. He did get the first verson of surefly and had problems until surefly sent him version 2 of the surefly like i have and then he did have any issues. Make sure you get the second version. 

Question about your SureFly installation...did you keep the standard plug gap or did you go more?  I also have one on a 252 and wondering which way is most common.

Love my surefly, one of the best airplane purchases i've made.  

Lost the field wire on the alternator once,  thing didnt skip a beat even at 8 to 9 volts.

I would install a second with a backup battery, if they let me.

I have tempest fine wire spark plugs that i have heard have a nasty tendency to break off the wire if you try to increase the gap. Since the surefly fires on every stroke and the voltages are higher and longer duration, those plugs are wearing out at a faster rate than the plugs on the magneto side so when i rotate sparkplugs i keep the plugs that fire on the surefly on the surefly side just different cylinders as the electrode wears away the gap gets increased naturally from the wear so in essence the spark is getting bigger as the plugs wear out. By the time the surefly plugs are worn out the magneto side plugs will be pre-warned with a bigger gap than new so i will put them on the surefly and just buy 6 new fine wire plugs for the mag side since the mag needs the smaller gap a new plug has compared to the surefly spec. I hear you can buy fine wire plugs with the bigger gap but i had already bought my original finewire plugs before i installed a surefly and didn’t want to waste what i already had.

I think surefly says that their unit puts our 20,000V, the same as a Slick magneto.  It is 40,000 for starting. They also have you run the stock plug gap as well.

Question….

If we could eliminate the wasted spark…

(our plugs typically spark twice, prior to the power stroke, and again, wasted one, prior to the intake stroke…)

Would the plugs really wear out at half the rate?  Aka last twice as many hours…?

 

Plugs are goffle expensive… when purchased a dozen at a time…
