A way to test the clutch integrity is to put it in 4th gear, pull the handbrake on as hard as you can without breaking it and try to take off. You may have to accelerate a bit. The aim is to stop the car from stalling. If it tries to keep running or you can keep it going for a while (like 2 seconds) then the clutch is had it.

When the clutch is fully engaged, ie. your foot is not on it, the car should stall immediately no matter how hard you try.

If it stalls immediately, start looking at other things.

BTW. It would NOT be a good idea to rev it to 6000 rpm when performing this test as you'll end up like my idiot friend who drove his car through the end of his garage. Bloody GTS4 traction. 2000 rpm is enough.

My second guess would be to start looking at Turbo and AFM. Check for end play in the shaft of the turbo, in that model there should be none at all. Check to make sure it spins freely, however, don't spin fast. Just turn it half a turn gently. If it appears ok, next thing to check would be the wastegate actuator. With an air pump or mightyvac you need to simulate boost pressure to ensure the actuator is working at the correct level.

How is the fuel pump? Do a flow and pressure test on the pump to make sure it is flowing at the correct rate.

Are there any error codes?

Check to make sure the AFM is clean.

Check to make sure there are no vacuum leaks from anywhere. Get a water sprayer (like hairdressers use) and soak all hose connections while the car is running to check for leaks (you will hear the idle change when it sucks up the water).

Start with those things and if they don't help, post a reply.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
