What's your take on this. Has anybody ever tried them?

The idea is great, getting it to work in the real world is not going to happen. Last time I checked, elevation of cylinder pressure was key to making horsepower. For example, the v6 turd in my work truck sips 87 octane and even if it went into detonation it still probally would'nt make as much pressure as a hot race mill at part throttle with no detonation.The biggest problem those folks have is you can't make parts on a individual basis and keep cost down. Many different plugs would be needed and the average consumer isn't smart enough to make a informed choice on which product he needs. One size does not fit all in this case. These people could make a killing off the ricer market though. I wish I had thought of it first.

 

i think it would only work under a few certain conditions, unless the whole center portion of the plug blew out.

 

I think I'm going to try these out. I'm going to screw one into each ear, then get a bunch of azzclown ricers to speed past my house all night long, with their fart pipes FARTIN'! Then, when I blow my stack, we will see if the spark plugs do what they are supposed to do!

 

lol....

Yeah I gotta agree on this one... but if we are going to talk about odd things that screw into your chamber why can't we talk about something cool like Audi's DFI injectors? I still want to know how much PSI those things take to run and if they have injectors big enough to feed 100hp per cylinder.

Just when you think you've seen it all. Wow that's some freaky stuff.

What really bothers me (besides the fact I just KNOW this hs got to be crap) is that it claims to prevent damage from 3 totally different sources:

1. Detonation
2. Hydrolocking
3. Overheating

How many products do you know that can really address even one of those issues effectively, let alone all three at the same time?

Does anyone REALLY think that you need the same pressure relief point for all 3 of these things? Detonation is really high pressure for a short period of time. Hydrolocking is a relatively slow ramp up from nothing to bending a connecting rod. And overheating...... well, I'm not even gonna touch that one.

I'm with unstable bob on this one. I need to try these puppies out for myself.

 

More to the point.... what would it sound like when the relief valve opened up on those things?

Paint a mental picture for yourself........ that's right......... just relax and let it happen...........

You're driving your favorite bracket race car down a lonely road one night. Low on gas, you stop at the local station but they only have 87 octane. You put it in anyway, having no other choice. Exiting the station, some bad guys start chasing you, seeing the big wad of cash you flashed at the station attendant. You slip down a dark dirt road, driving as fast as you can. The engine starts to detonate and overheat after a few minutes on the cheap gas. Just then the dirt road crosses a shallow stream, swollen up a few feet by recent rain. You plunge in, keeping you foot on the gas the whole way. Water starts to pour down the carb, causing your motor to experience........ (you guessed it, boys and girls) hydrolocking, detonation AND overheating all at once.

From under the hood you hear your trusty prep spark plugs doing their best to protect your engine. Bleeding off excess cylinder pressure as fast as they can!

I ask: What would that sound like?

My guess: A rather wet farting noise?

 

holly shat .... must have been a nice blonde ..... the attendant

 

There might be something to it. Wilson Manifolds has brought the burst panel to the nitrous user market, they are required in blown applications at NHRA events. Its the same idea, just in a different application. They offer temperature indicating plugs as a starting point. You tell them what plug you require/use and they cut off the shell and install their unit. The application is going to be the power adder market and people who step out on the edge tune wise. The burst point is selectable by the user at order time. I however usually tune our nitrous combo very conservatively and am interested in getting more aggressive and putting the wagon solidly into the 8's.

 

Taking the product at face value, I can agree with you. However, the priciple is sound, in that it understands the connection of combustion pressure with detonation.Just how elevated a pressure are you referring to?Compared to normal combustion pressures, the pressures of detonation can be from 2 to 10 times greater than normal pressures.

There is in existance, no, not a figment of someone's imagination, a detonation control system that goes by the acronym 'PRISM' that utilizes combustion pressure to recognize the presence of detonation, and able to adjust the igniton timing accordingly. Simple in design, direct, and effective! It's pressure sensor is located in the spark plug location. IOW, the plug and sensor are one unit. This system can be used on any internal combustion engine, that utilizes spark plugs, and gasoline as fuel. FFT.
