Default what do u think is the problem? Slave or master cylinder?

My clutch gets soft during wot runs. I've changed the fluid to dot 4 and bled the system. I also wrapped the line to protect it from the heat from the headers. So i think either the master or slave is bad. But i'm not an expert or know that much about clutches so i need your opinions. So what do u think the problem is?

Thanks

Need more info to help. What mods do you have and what clutch are you running. Clutch might not be up to the task any more.

Ive had my stock slave go soft and stick to the floor, with 2 different stock slaves. then i bought a 01-02 updated slave. my stock master went bad too, when that happens, the pedal felt the same to me, but i couldnt get it into gear easily, especially going into reverse. replaced that with a ram adj master and never had a prob (knock on wood) if you have the money, get them both replaced at the same time and have the drill mod done too. and you shouldnt have to worry about any more problems! i still covered the whole master-to-slave line with high temp sparkplug boots and routed the line as far away from the header as possible just to be safe!

Thanks for the info!

I was considering buying an updated slave and a new master but i have one problem......My car also has a 100 shot and put down 431hp 555tq so i dont think this clutch will hold up. If i buy the new parts for this clutch i might want to consider buying a new clutch at the same time. What do you think?

I've been having these problems before i sprayed the car though

Well, everyone will have a different opinion on what clutch to go with, but based on my personal experiences, here's what ive gone with-

stock original that came with my car- not bad, but i didnt beat on the car too much then.

spec stage 1- got 13k miles out of it before it died along with my stock slave

spec stage 3- grabbed awesome while it lasted ( a whole 5k miles) the center springs kept popping out, causing me not to have a clutch anymore! (they all 4 total) kept breaking under warranty so free clutches werent bad but then i got tired of replacing them.

Ram Powergrip HD- grabs awesome, a bit more driveability than the spec stage 3, definately not noisey like the spec and lasts alot longer as well. had it since february 07'. started spraying a 100 wet shot on it in june 07' holds it great. w/o spray i put down 342/362. holds up to my 5k+ clutch dumps on 275 50 15 M/T dragradials. very happy with this clutch. i got mine from thunderracing when it was on sale, it was $380.00 then. Ram recommends using a billet flywheel with this too.

After reading some post about spec i want to stay away from them. I was looking at the Ram Powergrip HD earlier today and it looks like it might be a clutch i would use. It looks like we are making similar power as well. I want a clutch that will last long that is not very expensive

i would say in the power range that youre at, and the money u want to spend, the Ram would be a great choice. i cant remember exact numbers but i believe the ram's holding power was in the upper 600hp range

Thanks i'm going to do some research on the ram and see how everyone likes it. I will need a clutch that can handle 500hp and 600 tq. I plan on getting a cam in the next few months.

I had the LS6 clutch in for a while. Right up until I sprayed the car. Didn't seem to like the extra tq. I ended up putting in a Tex OZ700.
