Imagine the POWER created by installing a Tornado, dumping a bottle of A.J. Foyt endorsed zMax elixer into your tank, and boosting your plasma with one of these.

The TZPB mod, or something.

 

a little of all.......a little marketing experience.....no wennie experience.......

I do have an engineering degree.....never been my profession
I couldnt afford to live on that weenie salary

 

Did ya finish yet ? Whats the verdict Dave.......will it start ?

 

ok got the critter on. The wiring colors are exactly the same, no change for '01.

I installed the unit near the computer harness connector. All the connectors are attached away from the engine near the fenderwell.

I drove it around town, ran down to the mall and back, just did some normal street driving with it for a little while, nothing too rough so I can see what difference this has made. I like it! It gave the L more noticable grunt on the low end. I stepped into it on a straightaway and it helped on the high end also. It is making more horsepower.

I'm not sugar coating anything here. Just seat of the pants observation. I didn't really get the unit for the horsepower, I bought it for the gas milage. Most everyone that had installed the unit had an average increase of 3 miles to the gallon on their vehicle, so that is the reason.

Anyways, it is making a difference. I want some time to check mpg though.

 

I installed my PB on my 01 L back in December of '02 with 40,900 miles on it. On February 1 st of '03, I ran my new best 1/4 mile et. I went from a 12.532 @ 108.31 to a 12.531 @ 108.69

Did the PB account for ALL of that improvement? 'Hael', I d/k but at least I didn't 'back-up'!

It's still on and working at 64,500 miles now. Btw, I have not seen an increase in mpg and I track that every 3 or 4 tankfulls. I got 14-15+ mpg before the PB and I get 14-15+ mpg now. Again, I didn't 'back up'. Also, to back up Rob's position, I've never heard any detonation either at the track, on the dyno, or in daily driving.......and my engine has never blown a plug out(I just threw that in for 'laughs'.)

Dave, I hope you get better results than I did.

Before the discussion can continue, everyone needs to be on the same page. Detonation can mean multiple things. First is preigntion where the mixture burnes before a spark event. The second is when the spark starts the event but the rise in temp and pressure sets off another ignition source elsewhere.

With preigntion, the ignition system doesn't matter, since it isn't doing anything. With the other case, a better ignition system will INCREASE the chance of detonation. If more energy is put into the system, the flame kernel may grow faster (assuming there was a reason it wasn't growing as fast as intended), and the temps and pressure will rise sooner leading to detonation.

And think about multispark for a second. Suppose you have a tube of air and fuel. You light the tube at one end and let the flame travel a bit. Then try and light it again. Nothings gonna happen cause nothing is left to burn. Even if only 90% of the fuel is burned the first time, not enough is left to support a flame. I have some super high frame rate video (>50000 FPS) of flame kernel formation at a spark plug, some with mulitple sparks, and it makes no difference whatsoever.

If a stock coil has enough energy to light the fire and not have the spark blown out, then any igntion system changes won't amount to a hill of beans.

 

Thanks Dan

Just so everyone knows, I'm not here to sell the thing to anyone, I just had one that I wanted to install, so no problems here if people do not agree with the item.

Many thanks to all who gave input, it was much appreciated!

 

Could a test be performed by observing the spark plugs. For example ; only hook up the PB to half the cylinders and run the hottest plug possible? - see what the plugs look like after a few 1/4 mile runs...?
I may have some personal information on this; just need to get hold of a digi camera.
just a thought.

I can't add anything technical, this post is beat to death,
but I do totally disagree with it ADDING the change of Detonation. MSD has been a great add on to any vehicle for
decades now, people didn't buy tens of thousands of them,
cause they do nothing. A plasma booster is just another brand,
same concept, and I stick to my opinion that anytime you can dissapate more heat from the cylinder (which Multi Spark does),
you have LESS of a chance of detonation. And anytime you can burn what your throwing at it more efficient, again you stand LESS chance of Detonation.

I have written them for their answer on this issue, when they write back, I'll post it, EVEN IF I'M WRONG.
If I'm wrong, I'm wrong, but I still believe it's a great add on for Nitrous and all that extra fuel beingn throw at it.

WORKS FOR ME

 

The MSD boxes are great for racing because they are generally reliable. Unlike the ford TFI modules and GM optisparks and such. But if you've ever looked at an ignition trace on a scope from an MSD (6AL in this case), there are only multiple sparks at idle (5) and up to 3000 rpm (2). After that there is only a single spark event just like any regular old ignition system.

True, dissapating heat from the cylinder decreases knock, but it also decreases power since the chemical energy from the fuel is wasted to heat trasfer rather than mechanical work.

Total B.S. Multiple spark doesn't do anything to dissapate heat. Its a simple process. Mix air and fuel. Provide ignition. Ignition point grows into flame kernel. The more energy put into the event, the faster the initial flame kernel grows. If the flame kernel grows faster than it did when the engine is tuned, the mixture may burn faster and reach peak pressure to soon leading to detonation. One the kernel has left the area of the spark plug, there's nothing left to burn, and an additional spark just wastes plug life and electrical energy.

This is all pretty theoretical, though, and the direction things should move. In practice, you may not notice a difference, but it certainly won't get better. I have an engine that I can run on a standard GM LS1 coil, or a Class IV laser with > 4x's the energy, and at stoich and rich of that, they are pretty damn similar.
