Hesitation problem, feels like slipping clutch

[StewCrew]

So when I got the car, there weren't any nuts holding the CAS in place (sigh..). It did run good and still pulled hard though after adjusting it by ear. But I picked up a timing light and adjusted it properly. Right after adjusting it i decided to test drive it, and it felt like crap. It would spool up like normal but the car didn't feel like it was going anywhere. Almost like it was hesitant to pull. So now I'm stuck with the idea it may be clutch related? It just seems like too much of a coincidence to be related. So yeah, anyone have any suggestions?
Thanks, Jake.

If the revs go up and the speed doesn't it's probably the clutch.
If the turbo's spooling but the revs don't go up it's probably a boost leak.

Thats the thing though, rpms stay solid. I can have it floored in 5th going 40mph and the clutch wot slip at all. Not even a little. I let Lofty drive it (since he's one of my best friends and far more knowledgable than me) and he suggested it may be the center diff. Any thoughts on that either?

Also I don't think it's a boost leak since it ran fine last night.

If right after you adjusted the CAS, the car began to run like crap, how did your friend figure that related to the center dif? I would check into the timing a little bit more before attacking the drivetrain..

Install the CAS the proper way and then come back with the results. TDC.

I agree with saecho.... there is a proper way to adjust the base timing, it can mess with driveability when its wrong.

I appreciate the link saechao, and eviltsi for the advice. I had no idea I was supposed to ground the engine timing adjustment connector prior to even starting the car. So I did that and went through with re-adjusting the CAS, and it seems to run right for the most part. I brought the car to a meet today and I didnt really notice any hesitation problems. I'm going to re-do it one more time within the next couple days to make sure everything is right. Thanks a lot for the help you guys

Try this method
Best way to tell is to get the car under a massive load - get moving on an uphill surface preferably, though flat can work, and stick the car in 5th gear at around 30mph or so, then stick the pedal to the floor. If the rev's go up quickly or faster than your speed is moving relative to them, your clutch is slipping. If you just bog down and don't do much of any moving forward, you're all set!
But I doubt it's your clutch.

So if you don't have a oem crank pulley you can't check base timing right? Because like the underdrive pulleys don't have timing marks on them...
