Have a few clutch questions first is my pedal has like a half inch to a inch of softness before it feels like it has some pressure and when I'm shifting my revs hang when I push in the clutch

I figured that would help the pedal but will that change my Rpms staying up when te clutch is in ? Herd that sometimes happens with lightened flywheel but I'm pretty sure my clutch is stock with around 4k on it

With a lightened flywheel, the opposite is true. Less mass means the revs will drop quicker when you push in the clutch.

It sounds like the clutch is still engaged when you push it in to release it. I would just bleed the system. Im not 100% on that, but it will help the pedal play and it may solve both problems.

Ok will try to bleed the clutch system see if that helps when I bought the car the clutch felt like it was slipping a little after 5k but the kid I bought it from said the clutch has been like that sense he out it in an it's only got a few thousand on it. I just don't want to buy a new one if that's not the issue
 

Lightened flywheels make the revs raise when shifting.

does the clutch slip? you can't take someones word for when it was replaced. Take an hour to pull the trans and inspect it yourself then spend money if needed.

Easy test for slipping clutch:
Pull into parking lot and stop. Shift into 3rd gear, slip the clutch quickly, but gently. If it doesn't stall, clutch is slipping.

Otherwise, another vote for bleeding the clutch.

incorrect.

A heavier flywheel (I.E. stock) keeps the engine rotating due to the extra rotating mass. It also has a lot to do with low end driveability. For instance, take our stock flywheels at half-a-million lbs and throw on a lightweight aluminum unit. You'll notice not only are your revs WAY quicker, and likewise on decel. On top of that, you'll more than likely notice you also have to give it a bit more revs to get it going smoothly from a stop, ESPECIALLY if you arent running the puny stock turbo that spools stupid low in the rpm range. Thats largely due to the decrease in mass(which as i said earlier helps keep the enging rotating, in effect). Lightweight flywheels are designed with quicker revs in mind, so the engine doesnt have to work as hard throughout the RPM range, hence the increase in performance.

A perfect example is an F1 car, which has very, very little/next to no flywheel. Hence, why they rev so rediculously fast to redline, then back to idle.

Hope that helps.


As far as the OP, I'd definitely recommend both bleeding AND adjusting/checking your trow on your clutch pedal. There is a very detailed writeup on VFAQ regarding the procedure, complete with pics and step-by-step info. Start there first, and if it doesnt work at that point, then start thinking about tearing into the car to diag a malfunctioning clutch assy.

Stop in mid-swing with a wood bat, and stop mid-swing with a wiffle ball bat.

You stopping the swing = forces causing engine deceleration. Bat = flywheel.

Everyone should watch this video and adjust their clutch accordingly. Very important for proper release!
