Racepak for stick cars

[Mark Madison]

Dave, I use a RacePak SC1000 with the latest upgrades, not a v300 but good enough. You can try Right clicking the clutch icon and the "scaled buffer channel parameters" window will appear. To adjust for the countershaft ratio adjust raw data value "B" . for your M/D ratio.

Dallas, did you machine this yourself (magnet collar on the shaft) or did you farm it out to someone else ? We are class rule restricted to T5's and Tremec's and I am want to mount a sensor for the input shaft data logging on our G Force T5. Because of the transmission design and no one making a sealed tapered bearing, G Force prefers not to help us with this project

"Damn Yankee" sorry to take so long to answer.
No, I did not do the machine work myself. Chuck Buckshorn, friend, excellent machinist and long-time racer, actually made all the pieces. During the layout process, we discovered that the fill plug boss lined up, laterally, with where we needed to be on the cluster. The case was externally milled to adjust the angular alignment to the countershaft center line. I bought a length of, I believe, 1" aluminum hex rod that was machined into a combination fill plug/sensor adapter with o-ring seals. The split ring is very straight forward since there just is not sufficient clearance to allow very much variation of dimensions. I sold both of the modified Jerico transmissions without verifying that the design would work. However, the Jericos were replaced with Libertys, also modified by Chuck and they work with the standard Racepak clutch sensor and a single magnet in the countershaft split ring.

I think once I can find someone who can make the collar for the cluster gear shaft with the magnets, we'll be cooking with gas. Thank you Dallas
