PULSTAR Pulse Plug

[niky]

Forgot the link, but I looked it up.

Basically, there probably isn't much of an effect.

A flashlight lasts longer than a camera flash... that 2 billionths of a second versus 30 millionths is:

0.000000002
0.000000300

At those infintesimal time frames, the spark propagated is only propagated at the tip. Considering it doesn't go anywhere else but the tip of the spark plug, the combustion wave-front emanating from the spark remains exactly the same. The spark plug can't change the speed or intensity of the flame-front propagation...

To put it in another perspective... your gas is a stick of dynamite. Whether you light it with a lighter or a small blowtorch, the amount of boom is still the same.

Multiple point plugs (like Bosch Super Fours and Splitfires) were conceptualized as a way of making this wave-front bigger at the start (double or quadruple points of initial combustion = better coverage), in other words, you're lighting your dynamite at multiple points for a faster boom. But that idea didn't really pan out as planned. Ideally, the Bosch Super Four is supposed to be a superior plug, but real-life results from its use provide mixed reactions... from "it feels a little stronger", to "it runs like crap."

Apparently, the thing that really matters is that the tip of the plug is as close to the center of the combustion chamber as possible, so that the flame-front propagates evenly throughout the cylinder.

Now, this product claims to produce better combustion from using a shorter but stronger pulse? Probably not. It could arguably make for more consistent combustion, but that's it.

I'll believe it if I actually see dyno-testing by a respectable source. Dyno results so far haven't shown much... one is from a first-time poster in his forum, another is from a guy who switched from Bosch Super Fours (which, like I've said, run like crap on some cars).

I'm not saying, categorically, that they won't work. Some plugs actually show a 2-3 hp difference on four-bangers found in your common commuter car as compared to other plugs... but these "more powerful" plugs are often already OEM for the car (in the case of NGK BKR5E or 6Es). And if you want a shorter but stronger pulse, there's a simple way to do it... re-gap your plugs.

Their claims are, quite frankly... fantastic... and it would be interesting to see how their plugs test against brand-new OEM and common plugs on a number of cars.
