Accel says it has 10%-15% more energy than the OEM coils. Specialized high temperature epoxy resists shock and vibration, while increasing thermal conductivity. They feature advanced bobbin technology, highly specialized silicone magnetic steel cores, along with optimized winding, resistance and turns ratio.
If anyone can shed some light on what all that stuff means (or what any of that stuff means) I'd appreciate it.
It's mainly advertizing 'hype'. ALL coil manufacturers are faced with the same design parameters, they just embellish the obvious (which works like a charm from what I can see
) Just for laughs lets go through their selling points...
-10% to 15% more energy. Since coils are 'passive' devices (they don't add power to the circuit themselves), in order to supply an increase in energy they must draw that increase from the driver circuits (namely the DIS module). You should ask yourself if you 'need' that power increase because our DIS modules are already running very hard as it is.
-High temperature epoxy resin/increased thermal conductivity. They ALL use this (they have to). However, it would be remiss for the advertizers not to include this as a selling point.
-Advanced bobbin technology/highly specialized silicone magnetic steel cores. Again, ALL coil manufacturers use high silicone steel cores. This is done to optimize the cores for the design frequency and to minimize losses due to eddy currents and hysteresis. This knowledge is not new either... magnetic core technology has been well researched for the last 100 years. Again, it would be remiss for the advertizers not to include this as another selling point.
-Optimized winding, resistance and turns ratio. ALL manufacturers 'optimize' the design parameters of their coils. That is to say, they examine what the primary drive circuit load requirements are and what the output power requirements are and finalize their winding specifications based on that. Once again, advertizers are stating the obvious here. Transformer technology is not new and has also been well researched for the last 100 years.
Bottom line: you're reading an advertisement, not an impartial assessment of a product.

And what's wrong with the stock coil pack on DIS cars?
Our OE ignition systems are pretty damn good! They are very powerful. The only weak point is the 89~93 DIS modules (they are run hard).

Ive cut .5 sec off with a 5.0 using their coil and ignition modual combo..They clain .33 sec off a 3.8 stang time..Ya never know
Apples and Oranges. You are comparing a 'single coil' system to our 'multiple coil' system. On a 'single coil' system you run out of sufficient dwell time around 6,000 RPM; however we simply don't have to worry about that. Our coil packs require ~3ms to fully charge, and even at 6,000 RPM they still have ~10ms available to charge.
If your ignition system is working fine, installing another so-called 'high performance' coil pack will gain you nothing and may possibly shorten the DIS module lifespan. My advice is to save your money for something else that will actually improve performance.
