run away from nologic products, except their actual coils received good ratings some yrs ago.
OTHER DEVICES CLAIMING TO INCREASE SPARKS:
Never be fooled by any device that is fitted between the ignition coil and the distributor, and/or distributor and the spark plugs (sometimes in place of ignition wires) for which claims of increased power, multiple sparks, and better fuel economy are made. These devices have come and gone over the last 50 years, and usually consists of a sealed container in which the spark is forced to jump an additional gap or is partially induced to ground on its way to the spark plug gap. These devices can also be cleverly demonstrated to produce sparks the human eye perceives as being "more powerful." The only "increase" a gullible consumer can expect from these devices is an undesirable increase in load on their vehicle's ignition system.
"CAPACITOR" EFFECT WIRES with grounded metal braiding over jacket
The most notable of exaggerated claims for ignition wires are made by Nology, a manufacturer of ignition wires promoted as "the only spark plug wires with built-in capacitor." Nology's "HotWires" consist of unsuppressed solid metal or spiral conductor ignition wires over which braided metal sleeves are partially fitted. The braided metal sleeves are grounded via straps formed from part of the braiding. Insulating covers are fitted over the braided metal sleeves. These wires are well constructed. For whatever reason, Nology specifies that non-resistor spark plugs need to be used with their "HotWires." In a demonstration, the use of resistor plugs with "HotWires" will nullify the visual effect of the brighter spark.
Ignition wires with grounded braided metal sleeves over the cable have come and gone all over the world for (at least) the last 40 years, and similar wires were used over 20 years ago by a few car makers to solve cross-firing problems on early fuel injected engines and RFI problems on fiberglass bodied cars — only to find other problems were created. The Circle Track Magazine (USA, May, 1996 issue) test showed Nology "HotWires" produced no additional horsepower (the test actually showed a 10 horsepower decrease when compared to stock carbon conductor wires).
https://www.magnecor.com/magnecor1/truth.htmwant more spark install, it is all about reducing the number of inherent misfires in a standard ignition system. Reason I use plugs with a reduced center electrode. Presently using Champion Spark Plugs 8812. champion is owned by federal mogul now.
I did this at one time. I noticed slightly quicker acceleration.
Almost a direct replacement. They are the MP10 OEM coils from a CBR1100XX (blackbird), ST1300, 2000 sabre and all 2001 and newer 1100 shadows. The VTX uses this coil on the forward cylinder and uses the same numbered coil (MP10) for the rear coil but carries a different part number and is green in color. All others are black. They will be identified with MP10 on the coil, the Valkyrie's are MP8.
This coil reads 2.4 ohms @ 60 degrees F whereas the stock Valkyrie coils read 2.9 ohms. This is a 0.5 ohm difference which will provide higher voltage to the plug. The stock Valkyrie coils are also used on the ST1100, CBR900RR, CB919, GW1500 and the older shadows.
The MP10s are larger. Installation of the side coil is a direct replacement. The two under the tank will require longer bolts and the forward coil's bolt holes must be moved 1/2 inch forward by making an adapter bracket.
Don't use the CBR1100XX coils if u are using a dyna ignition, they will burn it up in two yrs even though dyna says the ohm rating is compatible.
I am back to the stock coils with the dyna unit.
