Just BLEW through my Southbend Clutch
I have mods in my sig, and recently just put on my buddies Edge Evolution programmer on the 60hp tow setting. estimating 250 WHP.
Clutch was broken in properly at stock power levels, and smooth easy driving for over 1,000 miles.
I have 13,000 miles of normal driving on the clutch, no programmer.
I have towed a few trailers on occasion. none over 6000 lbs.
I drive good, (1,100 rpm from red lights, nice and easy)
I NEVER do clutch dumps even offroad.
The clutch will hold just fine if I roll into the throttle in gear.
I was runnin top of 3rd gear today, went to bang 4th, and let 'er eat...... rpm stayed at 3000 and just slipped the clutch nasty. I wanted to make sure i didnt accidentally have my foot on the pedal or somthing, so i drove the truck normally and slowly for 20 minutes, let it cool for 45, then tried it again. Same result.
So, why is a clutch rated for 350 HP, 750 Ft/lbs slipping in a truck thats not even making 600 ft lbs???
