Am I causing clutch / synchro probs
Majority of vehicles I've driven, from motorcycles to 18 wheelers I have found they all have a sweet spot in the rpm drop that has the smoothest gear transition. I am new to this car and I am hearing talk of syncro damage or clutch problems resulting from a clutch not fully engaged. All I have driven....I have never fully engaged the clutch during shifting, and with no problems I might add. What is so special about this car that it causes problems? Maybe lack of experience causes the problems? I verrrry rarely grind a gear, a couple of times getting used to the short stroke gearbox. When I push the car I may have a split second off the throttle and an inch or so of clutch. I watch videos of these guys running there cars and posting their 1/4 mile times, and you can hear the long pause between shifts..a 1- 1 1/2 seconds from clutch in to full out between gears...man if you hit four gears you lost plenty time. It takes that second the rpms start to fall to commence the shift....the throttle release timed with the bump of the clutch makes for an effortless... smooth shift to the next gear. Dont see whats so different with this tranny V/S outhers. A ford ranger..130000miles and 15 years later I traded in with the original clutch and transmission....no problems.
Not sure if I'm understanding your post--you're powershifting without utilizing the clutch or not fully disengaging it when shifting?
If so, your tranny and clutch are going to be toast. The s2k is not a truck and shouldn't be treated like one.

Does not require any force to switch the gear...its actually a very smooth switch, with very little rpm/speed loss..I even find is takes a lighter weight of the hand to make the gear switch then does a 3 - 4000 rpm "normal" clutch and shift..
And I can agree...This is not a truck with a crappy 4-banger and junk tranny.
its a SPORTS car with a high performance motor and should have a tranny to match?

well i was reading to not do damage you must go all the way to the floor...jus dosent make sence to me....
and listening to the motor sound on most videos that is what they are doing. Unusually (to me) long pause between shifts. they are running for time so if they are going all the way, I figured what I read must be true. I just find it hard to believe you have to do this. I do clutch, but I only drop in about an inch and it makes a very smoth and fast shift.
If it is a no no...I dont see why....But i will change my habits.

Lets see if i can explain...Ok im running the car full throttle and rpm hits 8500(Personally I never run over),at the exact time I release the throttle I push the clutch about an inch or so,hit next gear and release...takes only a fraction of a second.
Also, shifting super fast with hardly any drop in rpm and slamming gears like you see those mad tyte drifto kings doing on youtube will kill synchros, even moreso with your AP1's brass synchros. There's rev matching involved with upshifting just as with downshifting. Give each gear the rpm it wants when you engage the clutch, whether going up or down in the gearbox, and this will prolong the life of your drivetrain. You'll know you got it wrong when the car bucks when the rpm is still too high or jerks when it's too low. Your synchros are working to make up the difference in both situations.
