Kenne Bell Boost-A-Spark

Has anyone attmepted or have used a Kenne Bell BAS on an SC? Seems like a cheaper option then an MSD box to have a little more spark energy, granted its not going to give the spark like the MSD. It also regulates ignition voltage similar to how the BAP works. They have 2 versions an NA, and boost referenced so the spark is not always jacked up when in vacuum. Seems like it would be a viable option as many different types of vehicles upgrade to the BAS when going boosted. Just opening this up for a general covnersation piece on ignition upgrades.

It looks like all they are doing is feeding higher than 12VDC to the coil. I assume that increases the energy in the secondary windings of the coils, but I am not sure what if any impact that might have on the coil drivers in the DIS module.

Maybe our resident electrical experts can comment on it.
 
How does the coil pack back feed to the DIS module? With the BAS you splice into the primary wire that leads directly into the coil. Looks like I need to do a little research into how the coil and DIS work with one another.
 
roughly... the coil pack receives 12v which is coming off the EEC- Power relay through the DIS module to the Coil. The Dis Module contains coil drivers which are designed to shunt the coil primary to ground. This builds a charge in the primary that when the dis disconnects the ground, collapses the magnetic field in the primary winding generating huge voltage increase in the secondary winding.

The switching transistors in the DIS module are not particularly robust. If the higher voltage on the power to the Coil will result in more current flowing through the DIS transistors, it may create a problem.
