Alright I’ve been looking over a few ignitions systems and wanted to know which would be the better ignition system for our vehicles. I am looking for a good solid spark from 0-7000 rpm and will be boosting between 18-25lbs. Here is the list of ignitions I’m trying to decide between:
MSD DIS-4
Ignition Box Output: Capacitive discharge
Circuitry: Digital
Rev Limiter: Yes
Timing Retard: One-stage
Data Acquisition: No
CD Voltage Output to Coil: 470 V
Current Draw: 5.3 amps at 10,000 rpm
Spark Output (millijoules): 170 Millijoules
Minimum Operating Voltage: 12 V
Maximum Operating Voltage: 18 V
Length (in): 8.500 in.
Height (in): 2.250 in.
Width (in): 4.500 in.
Ignition Box Color: Red
Coil Included: No
Warranty: One-year warranty
Quantity: Sold individually.
Notes: Designed for use with 6 or 8-cylinder engines with 3 or 4 coil packs only.

MSD Digital-6
Ignition Box Output: Capacitive discharge
Circuitry: Digital
Rev Limiter: Yes

Maximum Operating Voltage: 18 V
Length (in): 8.500 in.
Height (in): 2.250 in.
Width (in): 4.500 in.
Ignition Box Color: Red
Coil Included: No
CARB EO Number: D-40-31

MSD Digital-7
Ignition Box Output: Capacitive discharge
Circuitry: Digital
Rev Limiter: Yes
Timing Retard: None
Data Acquisition: No
CD Voltage Output to Coil: 535 V
Current Draw: 1.1 amps per 1,000 rpm
Spark Output (millijoules): 190 Millijoules
Minimum Operating Voltage: 12 V

--------------------------------------------------------------------------
PerTronix Second Strike Ignitions
Ignition Box Output: Capacitive/Inductive discharge
Circuitry: Digital
Rev Limiter: Yes
Timing Retard: None
Data Acquisition: No
CD Voltage Output to Coil: 200-800 V
Current Draw: 0.8 amps per 1,000 rpm
Spark Output (millijoules): 250 Millijoules
Minimum Operating Voltage: 9.5 V
Maximum Operating Voltage: 18 V
Length (in): 6.000 in.
Height (in): 3.000 in.
Width (in): 4.000 in.
Ignition Box Color: Silver
Coil Included: No
CARB EO Number: D-57-9
Warranty: One-year warranty
Quantity: Sold individually.

I’ve been looking at picking up the DIS-4 b/c of its batch firing capabilities but at the same time it has a low output compared to the digital 7 or the second strike ignition system. The price it relatively the same besides for the cheaper second strike system, so what is your opinion on the best system
