act reading

ok at the act sensor on the intake plenum(return ic tube) i did a voltage check while the engine was at full operating temp and indoors at 72f. based off of the voltage chart for that sensor it was at 2.99vdc( 69-70f ) i tried a second sensor to make sure the sensor was working correctly and had the exact same reading. my sc also has a 10% od on it. does this seem like a normal idle temp?


i also rev'd the engine a few times and the most it would do was a .05 voltage drop( 5-10f warmer)

with all over the hype about sc temp with od pulleys it seems to me that this is a little low?
 
You have to put a load on the motor to see any heat built up. Trust me on that one. Although idling in traffic on a hot summer day I've recorded ACT's of 200 deg.
