Hey guys, I was hoping somebody could help me diagnose something, I have an 06 mustang gt with Ford performance hot rod cams, jlt stage 3 intake, (some sort of dual clutch it has a ton of pressure) and a lito tune, I run the car on 91 octane as well, now in every other standard car I drive it seems that once I slowly release the clutch in first the car has no problem driving without me giving it gas (just smoothly cruising in parking lots etc) with this car its impossible for me to just release the clutch to get the car rolling smoothly, i have to give it gas and play with the clutch to make sure i don't die out, I recently picked up the car from a dealership and sadly they don't know what's in the car as far as the clutch, I do know that the slave/clutch release bearing is rattling (only when in neutral and the clutch isn't pressed down but so that might be a factor however, I've never driven a upgraded clutch but I was wondering if the problem with the car bogging and dying out is normal with higher performance or race clutches, also wondering if there's any other possible factors that any of you might of encountered that could be causing this, thanks guys

 

I think it is probably the cams that are causing you trouble, not the clutch -- pretty sure those cams sacrifice low end torque, so it is going to be much easier to stall at low RPM than a "normal" car -- you probably need to get the RPM's up to around 1,500-2,000 to get enough torque to launch smoothly without stalling.

I guess the clutch could be compounding the problem, by making it hard for you to release/engage the clutch slowly and smoothly.

Hopefully someone else with more experience with those cams will chime in, but that is my semi-educated guess right now.

 

I'd be willing to bet it is the cams as well. While it sounds like the throwout bearing needs replacement, it would not cause the drivability issue described.

 

Right on guys, yeah It would make sense, thanks for all the replies!
