clutch rpm sensor?

[James Bond]

anyone have input on setting up a clutch/input shaft speed sensor to monitor clutch slip? i'm not having much luck with my searches.

Most data loggers have a drive shaft speed sensor for measuring torque converter efficiency, you could use that vs your rpms and solve your problem

thanks for the reply. my question with this method is when to apply the gear ratio of a particular gear (1st, 2nd, 3rd...) to show the clutch rpm. with my daq i'd have to import the rpm values to excel to show the clutch rpm, then plot it. i think that i would just be guessing when the clutch was actually engaged.

I see what you mean, the only other thing I can think of is somehow getting that sensor on the input shaft of the transmission and having a reluctor wheel made that mimics the way the pickup was on the driveshaft, then the ratios would be gone. Sounds like a fun project!

i'm sure this has been done before. i need to do some more looking around. thanks for the replies.

Nice, doesn't look too bad. Don't even have to get into the transmission
