I was surfing the web today and came across pulse plugs as replacments for spark plugs. their technology makes a lot of sense and on a two-stroke engine I can see how it would have a huge gain for the $$ over any other mod you can do. Their website is:

http://www.pulstarplug.com/howtheywork.html

They cross referanced Champion BR9ES plugs for me and said their Pulstar BE-1 would be a direct replacment in the correct heat range. They are $24.95 each but, if they do what they claim their will be worth it. I am going to get some this fall and do some "seat of the pants" testing with them. I'll post after the test.

Very interesting technology there Mills,very interesting to say the least.Got to look up a cross reference for BR9ECS.Don't know if it will a big difference in a small engine,compared to car engines.
 
who says recreational vehicles are cheap and to keep them running is even more expensive.Only reason I am into sledding is because I live in the countryside,not he city.I can just jump on the sled and go,no trailering involved,no hassle of loading and unloading..fighting traffic to get somewhere to sled.If I feel like going for a ride at midnight...I just go.But the price to maintain these beasts are I think a little on the high side.So if you want to spend $100 on plugs...power to you.
 
Maxdlx,

Just call the 800 number listed on their website under the "contact us" link and then give them the brand and part number of the plug you are running now for them to cross referance.
If you can get 6-10 hp or maybe 10-20lbf of torque out of $100 and a 10 minute plug change along with better fuel economy I would rate this a relatively inexpensive maintenance/mod because to gain hp or torque with a sled you usually screw up the fuel economy. They claim to increase both so in the long run it would be a much cheaper mod if their claim holds true.

don't be in a hurry to throw your $$$ away. dynotech jim has done research on various ways to enhance power via plugs, oils & additives on his superflow dyno. to date, i don't think he has come up with anything that gives a significant increase to justify the added expense.
spark plugs do 2 things, ignite the fuel charge & wick away combustion chamber heat. if you want more power jet for the days conditions or modify the exhaust, fuel & motor.

i will be putting my 800 bender sxr on jim's dyno soon. if anybody has 3 of these plugs send them to me, or jim @ dynotech. i will do a comparison test to ngk br9es & post the results here. your plugs will be returned after the test.

I asked the company the following question:

I am interested in any testing that you may have done on 2-stroke applications (e.g. snowmobiles). In these applications the fuel burn rate is controlled in order to provide cooling in the combustion chamber, to avoid a potential burn down of the piston etc. Would there not be an impact on this process by using your new plugs?? Would it not be similar to using a hotter conventional spark plug (i.e. which is not a good idea). There have been numerous spark plug designs introduced (e.g. Split-Fire for one) which were supposed to deliver more efficient fuel burn but none of these claims ever amounted to much of a performance improvement.

In a four stoke application I can see where your technology might provide improved fuel economy and some level of improved performance, but there are more variables in the equation in a 2-stroke application (and messing with some of the variables can have disastrous results).

Thanks for your time.

Here is their response:

Len,

We have performed very little testing on 2-stroke applications with Pulstar as it is an automotive ignition designed ignitor. However, some of the Pulstar models will perform well in some 2-stroke applications.

Most 2 stroke applications take a colder heat range plug than Pulstar (NGK 7 equivalent)

We have completed significant testing on 2-stroke applications with our previous product DirectHits (see www.directhits.com). All 2-strokes run very rich mixtures to aid in the cooling process and prevent engine failure as you are aware. Adding DirectHits to “factory tuned” engines is a plug and play situation with no other tuning required. However, If owners re-tune the engine by leaning it out, then the mixture must be re-set to at least OE specification prior to installing DirectHits.

A “hotter” heat range plug is vastly different in that the heat range signifies the temperature of the ceramic cone during operation. The warmer it stays throughout the operating range, the “hotter” the number. If too hot the still warm cone/electrode will ignite the fuel charge prior to the ignition pulse arrival causing pre-ignition and peak pressures before top dead center and eventually engine failure, not to heat but pressure.

If you follow our information, what makes Pulstar and DirectHits different is the amount of energy deposited in the fuel charge during the incidence of ignition. We look at the power coupled at discharge which is considerably higher than any spark plugs which hover in the 50 watt range, while we are in the250KW to 1MW range depending on the voltage level of the discharge. This is why we call Pulstar a pulsed plug and not a spark plug.

They were prompt!!
 
Huh...this sounds pretty cool...it is a gamble paying that kinda $ for em...but it would be neat if they do work...
I remember back in the day with the Slick50 2 stroke additive people laughed and scoffed at the idea...I put that stuff in my ole KX125 after my dad had great results with the boat and car...within 5mins of idling the typical "ding ding" of a 2 stroke was gone...infact...I had to turn down the idle cuz it started to idle high...that bike had a few guys scratching their heads afterwards...the formula has changed now...but much like this Pulsed plug...it might be worth it before the oil companies snatch up the patent...

Keep us in the loop...fer sure
 
very interesting keep us posted

let us know if they have a match for an br9ecs and if they have tested them on sleds yet???this would be a benchmark for sledding if the results are there
 
Marty,
I talked with one of their tech reps and he cross referenced the BR9ECS's to the same Pulstar BE-1 as they did for the BR9ES. I asked for any detail on their 2-cycle testing so when I get it, if I get it, I will post it into this thread.
Mills
 
definitely keep us posted. I don't want to come down either way on this yet. Alot of these things end up being snake oil, but if noone ever tried a crazy idea, we'd still be getting around in steam engines.
 
The Pulstar people are sending me a set of pulse plugs to try in my sled in return for input on how they affect the seld as part of their R&D field test and feedback efforts. I have asked if they would like to have others test them. I haven't heard back from them yet but, does anyone else want to trial these plugs? If so, PM me with your email address and I will forward it onto the engineer I have been talking with.

Dynotech should buy the plugs and do a test as a report, you should not have to use your paid for dyno time to do it.
 
pz1:

if pulstar believed that their product was as good as they advertise they would send them to jim & ask him to do a comparison test to prove ther claimed results. they would then advertise the results & certainly increase their sales revenue dramatically.
for example when d&d ( who has their own dyno ) puts together an engine package they at times will then take it to an independent dyno facility to substantiate their claims. that confirms the credibility of their results.
my offer still stands. it is only one extra pull on the dyno.

Guys, sorry that I have not responded as of late. I am back in the middle of ND becaus my grandfather is near death and we expect him to not make it past today. So, I have been concentrating all my efforts on my family and the things that need to be done here.

From what I gather, the pulstar pulse plugs are more geared toward automotive and four stroke technology but, the company is very interested in two stroke technology and how they perform in two strokes as well. So, let's all give them a chance to work through the testing that needs to be done and then we can way-in on their benefit or lack there of.

Bob, when I get the plugs I will send them to you for your dyno test. I will also get you in contact with the engineer I have been talking to because i think he would most definitely like to see the results of your test and may want to use an outside source for test validation.
