New clutch slipping?

About a year ago a friend and I put a new clutch in my 2000 GT... a Ram HDX to be specific... and a factory re manufactured flywheel. Now the Ram HDX is supposed to be good to 450 hp... my Mustang has intake, exhaust, programmer.. so it's sitting slightly over stock numbers.. nothing ridiculous at all.. the other day i romped on it in 1st gear (which normally equates to going sideways) and nothing.. no spinnage.. then Saturday morning i ran it up hard through 1st, 2nd, and 3rd to about 85ish and shut it down, and came to a quick stop to make my turn at which time i smelled burning clutch..

now, i have Wagner brakes on my car.. and if you lay into the brakes HARD it smells just like burning clutch.. but i haven't smelled that since shortly after breaking in the new pads.. so i'm not sure if it was clutch or brakes i smelled.. but what could possibly make an almost new 450hp clutch slip on a nearly stock car?

Do you see your rpms going up without the car accelerating? Does the clutch pedal feel funny or stick to the floor afterward and is the next gear hard to shift.

These would be symptoms of a slipping clutch.

What would cause it without very much use? Improper installation and/or breakin, oil contamination, a clutch cable setup that is putting too much preload on the pressure plate, excessive track use, poor driving habits.

88 GT CHI headed 351w 10.8 @ 125 - still figuring it out.
03 Cobra 2.3 whipple 10.7 @ 129 - sold it
04 Mach 1 12.7 @ 109 mostly stock - sold it
89 LX procharged 302 515 hp 497 ftlbs 10.7 @130 mph - sold it

i did recently adjust my cable so that the clutch engages a little closer to the floor.. it started after that.. so would you recommend adjusting it back out more to a stock engagement point?

move it back to stock and see what happens, you might have adjusted it a little to much and the TOB is putting a little pressure on the driaphram fingers and causing the clutch to slip. no harm in adjusting it back to see what it does

also if it "shakes" the car (like a Fu**** motor mount.) when you go to engage it in either 1st or reverse (esp. slowly) you can almost hear a harmonics sound..

happened to my friends '00 v6. and what it was, was his flywheel needed to be resurfaced.

try that cable adjustment first tho.. might just be that you put it alittle to close to the floor.

I shall try this.. another tidbit of info, shortly after adjusting the clutch the last time, i began to notice a very faint 'squeak' between gears.. but the strange part was that squeak happens in the instant of time between when i let off the throttle and just before i begin to hit the clutch.. but not WHILE i'm pressing the clutch, it's really strange.. well i shall try the cable adjustment I'll just go back to stock engagement point to be safe.. hrmpph..
