Has anyone tried the Brisk 360 degree firing spark plugs?

[F5 Dave]

Had a look on their site. Multi spark.

Some constants; there is only so much energy and a spark will take path of least resistance.
Open air test vs in a chamber compressed with gas may look different.
Makes for a cool video but slowed down will you see just one spark for each event? If so there doesn't seem much point, and if it was multiple sparks they would divide the energy.
So you are left with no shrouding as only advantage I see.

Not sure about that one or know anything about any of the brisk plugs, but pretty sure i have seen it mentioned that the Competition "shorty" plug is a heck of a lot cheaper than the NGK version.
I doubt that includes shipping them to NZ in euros though.

Fascinating to watch that transition!

In case any one is wondering what has happened to Adegnes.
It seem he has been watching far to many re runs of Sons of Anarchy.

The Vice grip side stand is awesome, what's the headlight.

Thanks Husa! Haven't been posting here for a while and just recently caught up with the conversation.
The headlight is from an old(duh) truck I think, not sure, found it in the woods...
I started this rat scoot project for a couple of reasons:

- Needed something interesting but relatively maintenance free to ride at rallies, The Spx is an ever changing prototype and not very suitable.

- With everything else I've built it's allways been about performance only, by focusing on looks I get to use my brain in a different way which turned out to be alot of fun! Try it!

- I need something to do in the garage on late nights when I can't run the dyno(noise) but there's nothing but dynoing to do with the Spx

- Becoming a badass was way overdue, who needs turn signals when you've got a middle finger!

I'll post an update on the Spx after the next dyno session on methanol/nitromethane.

They seem very prone to ceramic cracking at the first sight of detonation...

I have no hands-on experience with Brisk plugs, but it will be wise to assume that all spark plugs show this behaviour. If a plug has seen detonation, don't use it again. Compare the cost of an extra plug against the cost of a piston, a cylinder, a head and a plug...

This is the very reason the only plug I will use is the R7376.
The normal Iridium plugs dont have the rare earth ground strap, and it is not laser welded on - more spark energy needed and then it falls off.
The same plugs crack the ceramic at the slightest hint of deto, never seen this happen on the R7376.
The 5K resistance fails regularly on other plugs, going open circuit - never seen that either.
There is a reason the shorty plug is a stupid price,luckily the R7376 is the same nose configuration but is made in sufficient numbers to reduce the cost.
And no the competitions plug with supposedly the same nose, makes less power every time I have tested this, and that has been enough times to be conclusive.
Any plug be that the Brisc, or even the wank Splitfire things,are all a waste of time due to not having both rare earth electrodes.

[lodgernz]

Wobbly, do you have any recommendation for a 10mm 19mm reach resistor plug of the same sort of quality as the 7376?
R0373A? R0045Q?

[F5 Dave]

Well I can say with some confidence that the B7HS that came out of this TF isn't going back in.

[wobbly]

I have used R0373A before with no issues, it has an Iridium electrode and platinum ground strap the same as the other expensive types.

Thanks Wobbly. I'll start saving...

It seams they are prone to ceramic cracking det or not. I tried some in the 300 NSR and both cracked.

Good luck, I am looking forward to seeing the vid.

earlier in the day it would clean out and run pretty good then I went to a different spot and with same carb settings it loads up bad. turned one of the powerjet in alittle but maybe it needs to go more is the only thing I can think but I don't understand why it wouldn't run nearly the same. when I get it sorted out and running good I want to try nitro 10%. also I have some 2.5"x2.5"x16" chunks of 6061 to make swingarm extensions one of these days
