I saw an ad. for these plugs in the February 2008 issue of Scientific American. Website is http://www.pulstarplug.com. I've written to ask them about application to RX-8. Comments? Experiences?

 

even if they are legit, the stock coils can barley handle the regular plugs

 

Sorry but anyone who claims "pulse plugs deliver up to 1 million watts of peak power" is dodgy to start with.

 

https://www.pulstarplug.com/applicationguide.cfm

The BE-1 would work in the trailing but nothing for the leading (14mm thread, 21mm reach).

 

50 watts - in 30 millionths of a second

1 million watts - in 2 billionths of a second?????

that's the same spark energy spark in 66.67th the time of a regular plug...(supposedly)

so 50 watts x 66.67 aprox 3333 watts I would think

Sounds better...and interesting too, just not what they said.

 

Wonder if we could use DirectHits as they appear to just snap over the normal plug's end?

or if it matters as a description of our plugs sounds pretty advanced..

 

Spin, are you saying its feasible?

 

If the DirectHits are a plug-on thing to std plugs then sure it will work, if it fits - the plug will surely fire. BUT and it's a big BUT - will it do anything different than OEM.

What might be interesting is to try it with the new Mazsport ignition solution. That is supposed to make HP in the mid range for even NA cars, perhaps this would increase the range of gains to the top end? Of course all just dreaming as of yet.

Just food for thought as ways to try and eek out 1HP or 2HP or so here and there and accumulate some gains. What else do we have left except but SC or TC as Mazda isn't forthcoming?

 

I need to do some digging but I remember someone posting something nice and simple on the BS associated with these sorts of claims.

 

I did some searching and I found several sites and blog post about the the PulStar plugs and the DirectHits when purchasers (companies w/multiple vehicles and individuals alike) bought and tested them. They all started saying it sounded like so many other scams, but they wanted to see.........lo and behold they universally got respectable results.

Nothing outrageous, but something noticeable, and repeatable...couple miles per gallon improvement usually and the overall concensus was smoother running, better midrange power, things like that.

I did find one site that reported that they found that some types of coils didn't work well (they tested a dozen or so different), some did with them. Not sure if this has anything to do with the fact, easily overlooked on the site but mentioned by DirectHits users, that you need to have or purchase "non-resistor" plugs to use the DirectHits. The Pulstars themselves are non-resistor so that's easy, but the DirectHits are only the electronics, not the plug.

As we have resistor plugs, we'd need to find a direct replacement for the leading plug we use in a no-resistor version, while we could use the the BE-1 in trailing position as you noted auzoom. Wonder if the BE-1 would be "OK" in the leading position or is that extra 2mm reach uber critical? And if the non-resistor plugs would not function well with our OEM coils?

Alternatively would there be any benefit to just using the PulStar in the trailing plugs only?

 

It's completely possible, however it all depends on how much each unit costs compared with spark plugs and how long they will last. If they outlast a set of NGK Iridiums and doesn't cost any more ... perhaps it's a worthwhile venture.

Keep us posted on the results labby!

 

BE-1 $24.95 Site says they last as long as regular plugs, they say about 50K miles.

 

Resistror plugs are for AM radio reception and interferance of other devices, cell phones cb's etc.


Let me know if the direct hit works.

 

True, but the issue is ... Pulstar has no compatible Leading plug. So in order to use a DirectHit adapter, we need to find a plug that is NON-resistor that will work as leading (21mm reach). Then you add the DirectHits to that which contains the same thing that the PulStar does, as well as the resistance component.

NGK has a non-resistor 21.5mm reach plug same physical dimensions, not sure about matching the heat range needed though or whether the extra .5mm matters either. Anyone know of a non-resistor RX-8 leading plug w/correct heat range???

 

sigh....but of course...email from makers of PulStar

 

Again, I remember MM saying something about the majority of spark action is done by either the L or T plug...of course I cant remember which one

 

the leading--the car will actually run ok---not great--- when you disconnect the trailings entirely
oscd

 

Oh well, worth a try eh?

 

ugh damn i thought they sounded pretty decent and legitement

 

O'well Bad luck,

Any FWIW some reading (can't vouch for accuracy, independence or methodology!!)

http://www.sparkplugs.com/sparkplug4...fid=0&KID=3147 Check the dyno comparisons! I know not a rotary but a comparison at least.

How about using Denso plugs?
