Orange box.

Cool, thanks.  Didn't know if you had like an MSD set up or something similar.
1972 Dodge Challenger Rallye 340, AT, Code TB3=Super Blue, SBD=8/17/1971.  Yes, a Rallye without the fender louvers from the factory because of the body side molding option.

it seems they suggest a ballast resistor for street use....hard for me to accept buying a modern ignition system that must have a ballast. 
The claims of more hp may be true when compared to a system that was not quite right.   It's hard to find an honest hp gain when comparing systems that are working right.

Looks like a nice system outside of the ballast requirement.  Looks like they could have found transistors that will handle the current like other modern systems.

They probably did that on purpose knowing how stickler alot of us mopar dudes, dudets, and dooders are !! especially about making things look stock so they incorporated it in.  Who knows if it will decrease the failure rate of the ballast resistor  :clueless:

It's a 4-wire unit, so it does not rely on the ballast resistor to power the ECU. The resistor is only for the coil, if you use a coil which does not require a BR (ie one which has the resistor included in the primary windings), you don't need one (that's true for any 4-wire ECU).

It's funny how with the OEM resto crowd, no-one has come up with a 0-Ohm resistor yet... That would be the best way to have a stock-looking setup, OEM harness, and use a MSD Blaster 2 or whichever coil you want.

Easily done just solder a wire across the back of the ballast

that is one solution, but, I prefer to avoid the gimmicks....I think variable dwell and the right transistors would have fixed that  :)

                  i agree. you can send 500 times more voltage to the plugs,but, you better seperate and use good wire sheilds , or , ignition crossfire will break the very best built engines!  if you have a properly working, good quality system , properly adjusted , getting the correct primary voltage, i doubt there is much hp to be gained. if your eng. sees over 7k +rpms and has hi compression it may help some. the best gains are in reliability.   been there ...:2cents:

The coil that you are using requires the ballast resistor. If you switch to an e-coil, you will no longer have to use one.

I am currently running an e coil...Crane PS 91 rated at .43 ohm

Reading suggests it may work
