I think before I thought that it was just wheel spin from the surge in torque, but now I think it's the clutch engaging. If I rev over the 3k and it happens and then decelerate and try to hit 3k to hear it again it doesn't happen, unless I come to a stop and accelerate again. Now, I've read a thread or two over on mbworld and they said the chirp was normal as the clutch and pulley age, but I would assume the clutch should be engaging somewhere between 1600-1800 rpm. If what I'm hearing is my clutch engaging, I don't know why it's not engaging until 3000 rpm. Should I be concerned? Any thoughts are appreciated.
I recall a post of Dave's (180) in which he added a page from the SRT6 tech's service manual I think it was. I tried to find it but struck out. It explained all the factors (parameters) that trigger the SC clutch lockup, and explains why it happens at different loads and R.P.M.'s. I recall it mentioning the "3k rpm" lockup point as well. DAVE, I hope you remember this; and could you please post that again. I thought it was very informative, and feel it would be very helpful here. Woody's old video that suggests it kicks on "at around 1,300" was informative, but I noticed that in his video it kicked on at a much higher rpm in one of his running tests. It does not just lock up at only a particular R.P.M.
