Well, it seems my clutch is slipping. If I open the throttle fully in 4th gear, there is noticable slippage and it's worse when rowing through the gears. My truck is modded, and will likely get more goodies in the future, since we've ruled out the possibility of a new truck for the forseeable future.
I'm running about 9-10psi max right now, but have room for more before the EGT's get too high. Currently, I'm out of fuel, as the DPS pump can't keep up. I'm planning on some Moose fuel products and some MLS headgaskets and ARP studs nest summer. For now, though, the truck has to be a daily driver and tow rig, and for that I'll need a new clutch.
I'm unsure how I feel about the DMF setup. The factory one provides nice and quiet operation, and has been flawless for the 112k miles it has on it. Clamping force is probably fine for my power level, as I think my slippage is caused by a worn friction disc rather than too much HP/Torque. I'm not very excited about the cost of a new DMF, however. Can I re-use my DMF since it seems OK, and replace the disc and pressure plate? Is that a recipe for disaster? I know the DMF is a wear part, and should be replaced, so I'm leaning towards replacement.
I've heard that SMF conversions are much cheaper, easier to service, and provide years of reliable service, but that gear rollover noise is higher, and the transmission takes a beating from the torque pulses of the engine. What kind of clutch was the ZF5 designed to be used with? Can I put some sound deadening material under the carpet to cut down on the noise? Will as SMF reduce rotating weight enough to provide a difference in RPM Drop between shifts? I know a lighter flywheel in my Supra made a world of difference in how I had to drive the car to get the power to the ground. I don't want my truck to be a nightmare to shift- the idea is for me to be able to toss the keys to my Dad and not worry about him having issues.
I've looked at Southbend clutches, but nowhere else. Please provide me with some reccomendations. My trucks specs are in my sig.
