Introduction:
The model 30-2852 HO Coil is a specially designed, high energy coil for racing applications so you must take
special attention with the connections. Apply a liberal amount of dielectric grease to the terminals and the tip of
the spark plugs. Failure to do this may cause arcs to the cylinder head and cause a misfire.
Kit Contents:
The 30-2852 Kit Contains:
1 High Output Coil
1 Mating Connector & 4 Contacts
Specifications:
SPECIFICATIONS:
Primary Resistance: 0.5 Ω +/- 10%
Primary Inductance: 4.8 mH +/- 15%
Secondary Resistance: 8.5 kΩ +/- 20%
Secondary Inductance: 22.5 H +/- 20%
Output (50pF load): 41 kV +/- 10%
Output Energy: 118 mJ +/- 7%
Peak Secondary Current: 100 mA +/- 7%
Arc Duration: 3.2 mS +/- 10%
Turns Ratio 71:1
Maximum Battery Voltage: 17 Volts
Base Dwell: 3.0 mS
Max Continuous Dwell: 9 mS but don’t exceed 40% duty cycle
Max Intermittent Dwell: 80% duty cycle, 5 seconds maximum
Mating Connector: Packard/Delphi 12162182 “Pull to Seat”
Mating Contacts: Packard/Delphi 12124075 “Pull to Seat”
High Tension Wire Terminal: HEI “spark plug top” Style
Pinout:
A: Battery Positive (Relay or switched ignition or high voltage input for CDI)
B: Coil Trigger (Charging when low)
C: Ground to Cylinder Head
Important!
The contacts are “Pull to Seat” meaning you must feed the wire through the connector housing BEFORE you
crimp on the contacts. The wire is then pulled back into the housing and the contact locks in place. The
contact cannot be inserted or removed from the rear (wire side entry) of the housing

Dwell:
When using in dwell controlled systems (i.e. non-CDI) the following guidelines should be used:
· Target a base dwell time of 3mS and only increase it when needed due to high cylinder pressures.
· The maximum individual coil dwell “ON” time must not exceed 9mS at any time, regardless of engine
RPM. Exceeding this time will cause the coil to overheat and fail.
· For continuous duty the maximum “ON” time must remain below 40% duty (on 40% of the time, off 60%
of the time). Exceeding this will cause the coil to overheat and fail.
· For short bursts, the coil dwell can go as high as 80% “ON” duty but these forays need to be short (under
5 seconds or so) and cannot be frequent.
