Thought some might be interested in this glow plug comparison, U an see the difference in the hot plug temp, "brightness" compared to the colder plugs " medium brightness", all they way down to just a very lite glow on the coldest plugs. let me know what u think.

looks like a Christmas tree. LOL

Seriously how doses this compare to how thy glow when running in a eng?

And what controls how much thy glow when running?
 
Dick, hope your doing well, I'd like to know where to find your plug post a ways back, can't find it?

Best wishes Mark

FIRE IN THE HOLE! That McCoy #59!! The plug I used to run 100 mph for the first time (1997). Burn more fuel = Go faster!

David, It does not compare at all, i wanted to show the difference in the glow plug temp."brightness" using standard 1.5 volts

@ 2 amps to give a comparison and what happens to the temp, heat, Brightness, as U go from a super hot plug to a very cold plug.This is in the area of what kind of igniter boaters use to start there engines. 1., seen any one cranking on an engine and it wont start, they have to stop cranking untill the plug burns off the excess fuel, usually they are using an ignition source that is a low voltage, low amp igniter such as the the small hand held igniters, even seem some using a D, dry cell battery. If u want to know if your igniter can burn off the excess fuel, hook your glow plug into your igniter and stick it in a jar of water and see if it still glows. If it does not glow this is the same as trying to burn a crank case full of fuel of until it starts.

2. what controls how much thy glow when running?

Glow plug temp and leaning, taking away the fuel. The hotter plugs, because of the wire design are much easier to burn the fuel as compared with a medium or colder plug. The trade off between a super hot plug that will burn the fuel easier but is much easier to damage or break, or using a medium plug with a larger diameter wire that takes alot more combustion temperature to try to burn the fuel.

There is more, however i just got out of the hospital on sat. 5th time since Feb and I need to rest to catch my breath, later.

Here is a testimonial for running the Mc #59 glow plug.

Part 2,

During my testing, I was able to determine and chart the actual failure temperature of a group of plugs, which led me to retest the same plugs with the same voltage but less amps depending on the particular plug in a time study of how long a particular glow plug would last while measuring the glow plug wire temperature and then adding this info to my chart for comparison.

Rest time, I will add more later.
 
Dick you just take it easy for a little.

Plenty of time later to talk about it and play with the boats when it cools down.

Come up to the Orlando race in October so we can spend some time talking.

would be my pleasure to help you with all the boat stuff no problem at all.

The hotel is only two blocks from the race sight.
 
I find this study to be quite interesting. I have seen some results like this in the past from my own testing but not this detailed and side by side. It also appears that the OD-9 is comparable to intensity as the MC-59. Would be interested in how the OD99 and OD blues compares to the group.

I am seeing more OB racers going to a hotter plug, with the MC-59 as the preferred one. Now the OD -9 can be used as well.

Well done Dick. Hope you get back on your feet soon.
 
OD-9's here in my .21's on 65%. Very durable & reliable plug for me, with easy starts & excellent performance. Very interesting info, dick. Waiting for more!

So, what if we could substitute a medium plug, or a medium cold plug, in place of a ultra hot or hot plug, and have the same or better performance throughout the entire throttle range weather the needle fuel delivery was in the rich mode or all the way thru the transition to the lean mode, would this interest anyone?

Come on spill the beans.

I know where you are going with this.

Unleash the GIZMO.
 
On board glow driver?
Well,U could call it that, however it is much more than a regular glow driver, I started working on the design about 2 1/2 years ago, I redesigned it a few times to add more functionality and safety to protect the IC components, it uses a single lipo battery pack for power, none reversing battery power jacks, I put a large heat sink on the 2 power IC's so they could not overheat when they are potted on the board, i used a non reversing glow plug lead, auto low voltage shut of on the battery set at 3 volts, I limited the glow plug wire temp to within 200 degrees of the wire failure and a few other things I will keep to my self, I did a lot of testing on this system, I built 2 just in case, I still have both units working fine, very interesting to start a nitro engine at idle and put the wire from the as "david calls it the "Gizmo" and listen to engine gain between 1000 and 1500 RPM.

Very Cool!

I've been toying with a similar concept based on using a micro-logic controller for it in conjunction with a few other automated items to make the engines more consistent throughout the duration of the run. An engine management system "so to speak". Haven't built or tested yet though, just been sitting on the "to Do list". I tip my hat to you for getting it done!

Intently, and understanding this correctly.. with the engine idling, or at an idle, this machine is then attached to the plug ?.. basically adding a voltage boost to the plug with the engine idling?... assuming a rich nominal needle settting for bank running, (plugs cooled by the incoming charge enough to keep ignition/idle steady,), what happens upon say, leaning the charge per the needle ( heat, hot, and the wire burns?).. does this machine regulate or keep constant the known approached "burn temperature" of the platinum wire, or, if you get third channel happy as i and so many others can, just burn the wire up anyway?.. in a nutshell the machine superheats the wire? regulates the wire?.... idk, with the plug being the weak link, we all normally face, adding voltage to it imo, looks to take it to a quicker failure.... per only, yes, when possibly leaning the charge down just that little bit more.... granted, and tested maybe, richening the charge upon engine operating temperature as it heats to aid the plug also, so what? in theory this super nova glow plug heating will allow more fuel burn?... should. IDK and wondering per, years ago, the Glow beast was the had to have item, and it was great... Double 2 volt D cells wired and freshly charged I could "pop" Mccoy plugs at will... I used the unit for turbo ignition plugs and it was the deal... they had to sing to be effective.... show us pictures Dick.... lets see whats ticking..... Yeah Bob, im with ya on the spark plug deal... lol, 'ceptin a co worker races the US title series, and they cant keep the centers in theirs either.... aint 2 strokes grand... test it up... Mike

Mike,

In your first question, "Intently, and understanding this correctly.. with the engine idling, or at an idle, this machine is then attached to the plug ?.. basically adding a voltage boost to the plug with the engine idling?", the OBI was designed to be plugged in when u start the motor, U could start it from another source however U would be missing one of the features of the OBI which is burning of any unburnt fuel and having the engine keep running even if it is slobbering rich without having to keep pulling the throtle to keep it running. The voltage is preset to the plug, which is higher than normal, there is a IC that does certain things and then regulates the plug wire temperature to within 250 degrees of the plug wire failure. does this machine regulate or keep constant the known approached "burn temperature" of the platinum wire, or, if you get third channel happy as i and so many others can, just burn the wire up anyway?.. IT WILL NOT STOP U FROM LEANING THE THIRD CHANNEL AND BURNING UP YOUR GLOW PLUGS!!!!!!! That is what it is designed to do, in the current boating world, everyone wants to get the very best speed by leaning down the third channel. I have sat at so many lakes, over many many years where there was testing going on or racing heat classes with 1 of my radar guns, only to see the same speeds no mater how much the third channel was leaned, and of course so many blown glow plugs, and i see from your post You have been there. Also, not all of the glow plug wires are manufactured the same as far as wire content, wire thickness and number of coils. when U keep doing the same thing over and over, such as blowing a lot of glow plugs, perhaps U could take a step back and analyze if there is a better way. During my testing it was pretty clear some of the glow plugs were able to withstand a lot more torture, however we had not been able to get these plugs up to a hot enough operating temperature to perform, "RPM", like the hotter plugs.

Double 2 volt D cells wired and freshly charged I could "pop" Mccoy plugs at will... I used the unit for turbo ignition plugs and it was the deal... they had to sing to be effective.. So, U see how fragile some of the glow plugs that we run are, The MCcoy 59 plug when hooked up to 2 volt d cell of course will blow the element, 2 1/2 amps and 2.2 volts is way to much current and amps for this

plug. The way I designed my gizmo, by using it on the glow plugs that are built better, with coil material and seals, the plug temp is going to be be within 250 degrees of the wire failure as soon as it is hooked up. If U are trying to get the plug temp up to super hot temp using the third channel, U have to go thru a process of leaning and listening and watching and hoping u do not far on the third channel. Do U keep all the blown plugs???
