forget bigger engines, you need these

Do they make petrol more explosive than ordinary plugs?

Seriously though, do they ignite better? I can understand using good leads and plugs with the right gaps but do they improve power or responsiveness?

Could you not just fit Nology leads? I was lead to understand they did the same thing. I'm also still not convinced that you actually need them on a well set up system.

If it looks too good to be true... It usually is!!!!

If it burns faster then pre-ignition will occur earlier so the timing will need to be retarded to compensate, thus reducing power.

Some of the figures on the site don't stack up where increases in torque and 0-60 times seem to be at odds across the model ranges.

There may be some benefits in economy and similar power from reduced advance but I would be keen to see independant results.

Now if somebody wants to donate a set I would happily provide a vehicle for back to back testing

The speed of the flame front in the mix is determined by the fuel quality, mix ratio, eveness of dispersement and size of atomisation - none of which would be impacted by the plugs - However if they set off a bigger 'ball' of detonation then you will get a small advantage.

Clever science - maybe cleverer marketing?...

what goes around comes around,

these look just like the things that were being advertised in the american hot rod mags in the 60's,
they said then they were developed for the military as normal plugs werent good enough,

more snake oil ?

"When the ignition signal is sent to a traditional spark plug, it begins to ionize the spark gap. This means that the voltage builds in the gap until a spark can be formed. During this ionization phase, which lasts about 5 millionths of a second, the incoming voltage (which has nowhere to go) heats up ignition components including the spark plug. This is wasted energy. "
As the heating effect in a cicuit is directly related to the current flowing throught it not the voltage across it. This statement is obviously a complete load of b@ll@cks!
One Megawatt for 30 micro seconds, equals more than 33 Kilo Joules. This energy comes from.................?

Even if it does waste some energy heating it all up, it's in a combustion chamber, and will waste a tiny amount of energy. If you run wasted spark, you're already wasting a full spark, so who cares about it?
As said, clearly not written by from a technical view point, as all voltages in open circuits like plugs have no where to go! That's why it's a voltage build, to create the spark in the first place!

so let me get this right, the plug stores energy for a while (which is the job of the coil anyway) and then releases it at a time that i assume is completley random ruining what ever sort of Megajolt system you have set up igniting the fuel whenever the plug feels like it....


and surely storing that volume of energy (that apparently comes from nowhere) will cause huge volumes of heat in the plug itself?

sounds like a crap idea to me...

Id think that once the engine is up and running, the spark plug tip will be sufficiently hot (from the combustion process) to mean that any heat "loss" due to the voltage will be absolutely negligible, if anything.

"One Megawatt for 30 micro seconds, equals more than 33 Kilo Joules. This energy comes from.................?"

To be fair it says it gives a megawatt for 2 billionths of a second, not 30ms (which is how long a regular plug arcs for), but still, another case of Snake Oil / electric supercharger me thinks.

Their claims gets better

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

Here they have a graph of BHP gains per $ spent. Considering they are $25 each and they are claiming $8 / bhp gain, they are claiming 12.5bhp gained on a 4 pot engine, or 25bhp on an 8 pot, but on what engine? You dont get a blanket gain on all engines so that graph is completely pointless.

What a load of testicular appendages. Before the spark gap has ionised, current flow is practicaly zero. Power = V * I, so no matter what the voltage, power dissipation is zero if no current is flowing.

As for the increased peak cylinders pressures, if it's true what happens if you install these plugs into a turbo charged engine, detonation city?


A total rip off, just like the overpriced, overhyped and under-functional Nology HT leads.
