How hard is this on the clutch? I am just thinking it would be hell on the clutch actually making boost at the line while the clutch is somewhat slipping. I may be wrong tho. I'm not up to date with preloading.

 

i never preloaded my car on the twin disk. I did before when i had a 4 puck. its hard on a twin disk.


are u guys doing this on a reg clutch or a twin disk.

 

i do it on my twin disc

it is ******* hell on the clutch. but its better than axles and tranny breaking well maybe not axles but trannys

 

im going to be doing this on a exedy 3 puck! i just hope i dont burn the clutch out in a few passes

 

Yes it's bad on the clutch, which is why I don't slip mine on the e-brake. Not only does it wear but it heats it up and can cause it to slip.

I'm using the RPS carbon carbon twin disc. Carbon tends to grab harder when you heat it up.


I took off the trans to rebuild it and i inspected the clutch.. it honestly looks like i have never even used it.. and i slipped the *&^&% out of that clutch.

 

Cool thing about using the ebrake is you can run your 2step switch off it!

RPS 6 puck here, no probs

 

maybe so, but your kinetic friction coefficient is higher than your static friction coefficient...so when your clutch is spinning and then you ask it to take more power...it will continue to slip until there is a 1:1 ratio between the crankshaft rotation and the transmission. Carbon carbon clutches just so happen to have a static and kinetic coefficient that aren't too far apart. And as you put more heat into the disc it brings the static coefficient even closer to the kinetic one.

lamen terms?

 

I think he is trying to say that with carbon carbon...the heat actually helps the clutch hook better? How heat helps a 1:1 ratio, thats the thing i got lost on.

 

Everytime I've tried preloading the clutch it burns the **** out of it so I quite preloading and just drop the clutch at the line. Didn't break anything last time out.

Expand if you could? Which companies allow the ebrake to run it? Or is that standard across the board if you wish to do it that way?

It's run off a brake switch so it can run off of anything.

Pretty standard across the board, use the ebrake light switch for signal. Depending on the input required for the 2 step you made need to run a relay, thats about it.

 

Thanks. Never realized that.

Holy mother of back from the dead. i was reading all of this and seen one fab and i started thinking to my self when the expletive did they come back...lol then i seen the date

 

i started practicing preloading on the line. I prestage, pull handle about half way just enough to stop the car if it rolls, then i use that to stage. I slam down the ebrake when i launch, no need to hold the clutch in a position because everything stays preloaded if you stage with the ebrake pulled.

 

I was thinkin of putting a Line lock on the rear brakes n run it to a switch on my steering wheel and make it soo when u hold it its locked n when u let go its not Be just like a tranny break n good for burnouts tooo

i think its easier to use the ebrake.. i wouldnt put it on the streering wheel either.. just imagine if you accidently bump it while moving?

 

Keep in mind for the line lock to hold the brakes you have to push the brake pedal down hold then activate the line lock. Nothing would happen if you were to make a pass and accidently hit the button if the brakes were not applied as well.
