Time for a new clutch?

I have just shy of 83k miles on the original clutch.

Today I got my foot in it hard a couple of times in 2nd and 3rd. When the boot came on the RPM shot up as normal, but while the car hardly accelerated I didn't get that JATO pack feel. I didn't get any clutch smell, but seems to me unless something has suddenly gone out of whack its time for a new clutch.

Does the panel concur?

Was adjusted fine 2 years ago, I haven't been back underneath the car since then, I'll check it out soon.

I would think if it's slipping enough for you notice, you should smell it.
Of you do need one, talk to TK. He sold me a lightweight clutch kit that works well at your power level. Uses a much lighter PP for faster revving. He doesn't recommend a LWFW generally. Not much weight saved, especially compared to the pressure plate.

Check for a massive boost leak. I had a similar problem.

No massive boost leak, boost gauge is pegged, the engine runs smoothly, doesn't go wildly lean or rich or bog down at all. RPMs spool up rapidly and smoothly, slightly faster than normal, the car just doesn't accelerate as fast. I see the tach needle zoom around, but the car just doesn't go. I'm not popping the WG, its not overboost kicking in, everything is normal.

Slightly less hard on the boost and everything is normal.

I would have expected to smell clutch as well, but its the only thing I can think of.

It could be clutch slip - if the rpm are going up and car not moving. One thing you could do is slowly take the car up in speed - 2nd or 3rd. Watch the tach and mph. Pick a number - eg 4000 rpm, check mph.
Then do it again full boost. Check mph at 4000rpm. You may not smell the clutch given it is behind you.

When my pressure plate gave up the ghost, it slipped easily in 3rd on full boost, and slightly at the top rpm range in 2nd. There was no lead up to this failure, one day it was fine...the next it was toast.
Never smelled the telltale burning clutch disc...but then again, I never let it slip for any length of time. I knew what was up and just ordered a whole new clutch package from Chris at TK.

If you deal with Chris at TK, you will get the correct clutch assembly for your application, the price will be fair and competitive with other sources.

What you will get for free is the right advise, equating to the right parts, equaling no screwing around during install or function.

My .02 cents worth.
