FAQ: what do I need for the MSD ARC module 7761? 3 things, the MSC5 sensor above, the L-bracket below and one of the 8 magnet collars above.
Also, in the case of the Sportsman or IQ3Drag dash you must limit the number of data items sent from the Grid to not exceed the open channels in your recorder. 9" Ford L-bracket

Clutch Sensor in Jericho
Thanks to Jim Schaechter - Stock/SS racer from IL for these pictures and description.
The oil fill on the sie of the case was drilled larger and tapped for approx 1". Then a 1" stud was center drilled & tapped for the Racepak 3/8 sensor. Also the 1" stud was countersunk on the outside end to allow clearance for the moldend rubber where the wire goes into the sensor. A 3/8" jam nut on the inside for the sensor and a 1" jam nut on the outside complete installation.
The collar is custom made with 2 magnets. |
 |
Thanks to Dave Casey and Mike Sparago, New England Stock/SS raceers for these pictures and details.
This is the collar. Note the .030 magnet retention shoulder - just like a on a DS collar. |
 |
This is a slightly different location for the sensor and uses a Racepak drive shaft sensor rather that the clutch sensor. The case is drilled & tapped directly for 5/16 threads used on the RP DS sensor.

Lenco Drive Info
MONITORING CONVERTER SLIP IN LENCODRIVE EQUIPPED CARS
Racers using the Lencodrive automatic transmission have an added advantage of being able to monitor
the ‘slip ratio’ of their converter. Just as we do on clutch-equipped cars, where we monitor the input side
of the clutch (engine RPM) and compare it to the output side (transmission input shaft) to determine
clutch slip without having to calculate transmission gear ratios, we can now do the same on automatic
transmission cars that are using the Lencodrive transmission. The problem with trying to do this on
automatic transmissions before now was access to the output side of the converter.
All Lencodrive cases manufactured since early 2005 now have the provision for installing an RPM
sensor in the case. The 3/8-24 hole is located midway in the case at approximately the 3 o’clock position
(when viewed from the rear). The hole will by plugged with an Allen pipe plug. However, not all
Lencodrives have the magnet installed in the ring gear on the drum. To monitor your converter slip ratio
it will be necessary for you to have Lenco install the rare earth magnet that triggers the sensor. The cost
is less than $50.00. You can contact Lenco at 619-287-2500.
The upgrade to monitor converter slip with Racepak V-series data recorders is $260.00.
