Drop or Slip?

[Addicted2Boost]

Who drops there clutch in a TSi awd, and who slips there clutch. I've dropped my clutch twice at about 6500 and it jumped and just bogged down which didn't seem like it was better for a 1/4 mile time. Then i just held it at about 6500 to 7000 and just eased the clutch out, i'm not sure if this is what you would call slipping it or just straight up burning and when i did that the car pulled pretty hard. If there is a diffrence between slipping and burning a clutch can someone explain it to me please, i'd rather not keep burning my clutch in the future when i start racing on the streets. So if someone can explain slipping and if its diffrent from burning the clutch then i would be very greatful. I've a ACt 2600 xtr pressure plate for a clutch

if you just straight up side step it you'll send your drivetrain to hell in a very short time.

a fast slip is the best way out of the hole

i find if i try to ride my 2600 hard it spins, small slip then kill the fawker

Top fuel cars have special centrifigul clutches designed to slip at lower rpm on purpose.

Slip the clutch... If you drop it you will drop a transmission...

Also depending on mods you could have more power at lower rpms than stock...

I cant see any reason to launch above 4000 rpm with a streetable sized turbo... Race only cars with like T-66 or something... yes.. But then they are just getting started at that RPM...

IMHO 3500-3600 for most people based on the average turbos boost point... Its easier to do than 4500 because it's easier to slip and you don't have to bleed off as much tq into the clutch via slipping... It will work better and the clutch will last longer. It should feel like the going up part after hitting the bottom for those who have bungy jumped..

Stopped, then gradual accelaration. Should push you back in the seat but not slam you around..

so i should drop around 4500 and only hold the clutch in for a thousandth of a second if i want to get the most torque. Last night i was at a red light with a 90 ford probe Gt and i had it reved at about 6500 and once that light turned green i slowly let out the clutch and then i let it go once i saw the rpm start rising up to about 7500 and once i hit second my car was out. The only thing that sucked was the smell. thanks for the help if anyone else has any other usefull information on slipping the clutch in an awd talon then i would glad to hear it im open for all ideas and new things as long as it doesn't blow my car up. THanks Alot Guys

More like 3500.... More RPM = more clutch dust.... Get moving at a lower RPM splip a second and put the power into the tires and less into killing a clutch.. 1st gear is geared pretty low.. Once your moving you will have no problems seeing that tach move so why rev any higher than needed and break stuff.

damn it i think i laughed for 5 mins straight after i read the dropping the clutch at 6500 on a awd car, u might as well unbolt ur tranny and driveterrain and put it on the ground it. Its easier on the fwd cars if u drop the clutch but the awd wont exactly let the tires spin so easily, remember the whole car is pressing on them....duh.

anyway to get a good take off, and this does wear the piss out of the clutch, and takes a long ass time to get used to, pull ur ebrake, once u gota feeling that the lights gona change soon, rev the engine about to 3000rpm and slip the clutch so u feel the car trying to go, dont stall it, once its green, this is the hard part, u gota let the ebrake go give a uick rev+slip to the clutch and then drop the clutch and go, it sounds dumb but wehn u get it to work it is like a sling shot, ive done it on my dads '69 455 firebird and my sisters corrolla type -s, i know thier both not awd but its the same concept for all of tem

I run line locks so I dont E-brake.... Triggered like the two step off the clutch pedal (an "armed" switch too) But you are right...

Start doing granny launches.. 2000 rpm then work up.. Only go as high as you need to. You should have NO slamming, jerking etc and once you are good and doing it at a sane RPM 3500-4000 you will only slip a much shorter amount of time as before.

I used to drop but have gone to sliping since early last year. In my last runs have been slips it saves the drivetrain it saves the tranny. I slip from 3500 to 4000 works great. People say I am crazy it is AWD car drop that Sh!t. I just ignore em. There is a Galant VR4 that runs 13's sliping from 4000 on his ACT 2600. To me it just makes more since.

Burn a DVD and sit infront of a big screen and drive the air DSM like he does the real one.

That is like 5,000-6,000 or so but it is a huge turbo... so it's not as bad as you think because a extremely lower rpm launch is'nt possible... + he know what he is doing and still made it progressive and smooth.

so i should drop around 4500 and only hold the clutch in for a thousandth of a second

No more like a few seconds..

Did you see the tach needle like hang at the same RPM thru launch untill it was time to feed out the clutch... ? It will sit at launch RPM for a while and as the car gets going and you lift the left foot a bit faster move out... Blink and you need to grab second.. Basically sliping means slowy letting the clutch out gradually changing to quickly letting it out as the car pics up speed.. Slip the clutch untill the cars forward speed matches the RPM. Like if you rolled out slow in 1st you would be doing X mph at 4000 rpm.. When you reach that forward speed you should be off the clutch.

 

[paranoidTSi]

don't HONDA drop your DSM (REDLINE, DUMP).

With a stock turbo..I kid you not..dropping it between 3,000 to 3,5000 RPMs was the BEST I found...its grab and go with my car.

Of course if you want your car to be reliable..you'd be better off slipping it..hard on the clutch still but not AS BAD on the transmission.

The question about burning the clutch when slipping it out..thats normal and its going to happen weither you like it or not..dumping it does the same. If you are burning the HELL out of the clutch you need to slip faster than you are doing.

 

[BGRIPTP]

Floor it, hit 5500, build boost, slip it... Still haven't lost a tranny with the two step.

 

[MNGSX]

3500-4000 is my most ppl beginner settings... Small turbo, no stutter box... etc...

I launch higher but I spool later than most.. IE most EVO 16g etc....

Its easier to get the hang of it lower... Then move up.

hey a when did slipping and dropping the clutch become the same, ever thought whats happening when u dump the clutch? it doesnt slip that much all of the pressure goes on the driveterrain, especially if u have awd because more things to spin and again u have all 4 tires to spin, when u drop the clutch SOMETHING HAS TO LET GO and in a good case its the tires roasing, in bad, its sincros, anything from halfshafts, pressure plates, gears, transfercases u name it.

just go along with mngsx's n my statements, i think they make the most sense out of all of these..

and if u smell ur clutch thats very bad also, it means ur burning the #### out of it

Same ^^^

 

[pianoman]

I usally bring it up to 5500 then start to release the clutch as soon as it starts to grab i let go of the clutch and mash the gas. Just make sure your radio is screwed into place pretty good or you'll miss third.

 

[Denji]

since we are on the subject, i have my launch down, but i would like to know about 2nd gear. When i hit second gear is it better to dump the clutch or slip it and why?

 

[Addicted2Boost]

wow thanks for the replies. i tryed a slip at 3500 tonight before reading this post to see the out come it and it worked pretty good although i kinda just stopped once i hit about 5 grand. ARe you able to get the tires to spin on a awd drive car?(stock is what im talking about)

 

[Denji]

if i shift too aggressively my second gear spins.. however it didnt until i put my new clutch in.

 

[MNGSX]

Don't try to spin the wheels on AWD. That is like trying to switch a new vette to FWD.

 

[i'm boosted]

I just wanted to add my two cents. The condition of your supension will affect your launch RPM. When I first took my car to the track with my worn out stock supension, I had to launch the car at 5500 RPM (Slipping not dumping). Once I replaced my supension, 5500RPM made all four wheels spin off the line. So now I launch at 4500 RPM. I just installed a lightweight flywheel so I may have to raise my lanuch RPM

 

[THE_ARTIST_]

6500-7000 is too high of an RPM to launch at...unless you want to break your tranny
try 4500-5500 and slip it

 

[MrPikolo]

I recommend just going to the track and making a bunch of test runs while trying different rpms. One thing everyone can agree on though is do not drop the clutch, there is no point. If you rev it up and drop it, not only will you not get as good of a time because your wheels will spin more, you will risk breaking something in your drivetrain.

For me, slipping it out at abuot 4,000- 4,500 seemed to work best for me. I've pulled a couple 1.6 60' and constant low 1.7s on shitty tires.

 

[Addicted2Boost]

I slipped at like 4k to 4.5k and man that shit ####in Pulls. thanks for the help once again Woot
