F1 service and awesome clutch wear

So...if I understand Erik's explanation right...with the Duo-Select Transmission, we should NEVER go to Neutral when sitting at a stop light, as the throw-out bearing will be engaged for the entire time.

Throw out bearing is always engaged when the clutch isn't closed in contact with the flywheel. i.e. any time you're stationary and the engine is running.

I think I would just drive it normally. All the shifting around in neutral is just putting more wear on the pump and the actuator..If you are driving a car, you are wearing out something..Jason

I'll stick to my "shifting around in neutral" because it's cheaper to replace the pump than the clutch. Reading through the archives, plenty of F1 clutches dont make it past 20K miles. I have a feeling it's because they don't drive it like a true manual. My previous F355 went 42K miles on it's 1st clutch before I sold it. Yes, I agree wear and tear is always a factor. I just try to mitigate where it goes.

The Ferrari clutches last longer because they don`t slip the clutch much at all on a F1 car..It's like a on-off switch...A QP on the other hand must slip the clutch as it's a large luxury car...Clutch slippage = clutch wear...I fail to see how shifting to neutral does any thing to reduce wear on the clutch or anything else..The more you shift the car, the more the pump has to run and the more times all valves and actuator must work...I don't get it, but to each their own...Rather than dick around with neutral..Have your shop set the car up with a low PIS so it doesn't slip much..Jason

Jason, is it possible to reprogram f1 ecu to make it work as Ferrari without slip? Or it is because QP weight only?

My regards!

+1 +1 +1!

It's all about slip, at least with the friction discs. 50% of your wear is in your takeoff from a start. These cars are known to slip up to a full second before full engagement on a takeoff. Everyone asks me how I get so many miles on a clutch with my aggressive driving when theirs burn out at 20K. It's because of the takeoff. I ALWAYS give a little gas, let the clutch engage, then accelerate. Yeah, all the cars pass me at the light, but I catch up. And, I save thousands. Cut the slip in half and you double your clutch life.

Do you know this for a fact ? Like you are the original owner? I have never seen an original clutch in a QP last anywhere near that? I think if you could get 50K out of one then you are doing great or live in the country....Jason

My QP had its first clutch change at 98k miles....

I think this is possible but only under nearly all highway driving conditions. When you're on the highway, there's no clutch movement, the pump hardly ever primes and all the torque is headed to the gearbox, so there's pretty much zero clutch wear.

With the exception of one 5,500 mile highway trip, mine was almost exclusively city use - To and from work, various business meetings, bars, strip clubs, many inevitable drives to drop off various women at thier houses at 3am, unless of course, she lives on a dirt road - sorry babe, no can do. Car's clean. It's only a block, you'll make it.

So, now I just enjoy the car the way it was meant to be and I never worry about clutch wear. The girls on the other hand - they must wear comfortable shoes.

My QP made it over 46K miles on its first clutch, being exclusively driven by old men (the first two owners) in Auto mode. The second owner used it chiefly for long trips, so that's the reason that happened.

I know that it saves the clutch to accelerate gently until it can engage. And yet, I just love the way the whole system works so smoothly when you jam it! It seems to *want* to get worn out fast. Lotsa throttle from a stop and its quite a thrill. It seems to work a bit better with MSP turned off, because then you've only got the mechanical LSD preventing wheelspin without the computer figuring out how much clutch slip it will need for X amount of gas.

The way I see it, I'm spending over $5000/year in maintenance on this car no matter what. I'm currently driving about 6000 miles/year at most. I don't really know how much clutch life I'll get but if it's 20K miles that's still more than 3 years of driving. Clutch job is $3,500 or so. Meh. It doesn't really add much.
