Launching w/ a ACT 2600

[Black_90TSI]

I have owned 2 other talons before this one but they both have had stock clutches. The talon I drive now has an act 2600, I have tried to lauch it acouple of time just by slipping the clutch out. I have done this w/ both of my other cars but w/ this clutch the car just falls on its face. Is dumping the clutch the only thing to do or am I just not use to this clutch yet. All input is apprciated. thx

 

[chrisAWD]

you have to let it out easily and linearly(is that a word?). The clutch will grab hard and unless you are giving it alot of revs, you have to go slower than you would with a stocker.

 

[Black_90TSI]

Thanks for the advice. Can't wait till the track opens back up here. Looking to get some mid to high 7's passes.

 

[RipperXX]

You can also adjust the clutch pedel so it will let it out slower...

rev and dump

Bad advice there.

With awd you will want to rev up above 4000 rpm's and then let the clutch slip then engage.

If you just dump it it will bog like hell and you will get beaten off the line in an awd car.

 

[eyebrowski]

if your bogging with an awd dump you ar not launching hard enough. i launch arounf 5500 rpms with a dump and my tires chirp and sometimes spin without any bogging. its a little rough on your tranny but if you are looking for those sub 2.0 60 foots this is how you gotta do it.

 

[hostile]

If you think sub 2.0 times are great 60 foot times your confused with FWD cars.

My friend just ran at the track the other night. First way he did it your way.

2.1 60 foot. This is with a 2 stage rev limiter and 6 psi off the line.

The next time I had him try it my way, Rev up to 5 and slip the clutch out like your leaving a stop light, as soon as you feel it move let off as quick as possible.

His 60 foot dropped down to 1.8 and he took half a second of his quarter time.

The launch is so much smoother and the power all makes it tot he ground, instead of just hopping out and then trying to regain your revs.

I rev and dump also. Take it to 5500 or 6000 depending on track conditions and I've got 1.8's with that method. I think if your slipping the clutch with an AWD you aren't taking advantage of it. Oh well, we all have our own methods.

i was holding rev's around 5,000-6,000 RPMS, and slipping clutch and flooring after that and was pullin 1.8 60 foots.

then i tried a 6,000 with a very fast slip, and pull a 1.7 60 foot.

 

[44pirate]

I rev to about 5200 and do a two step dump. Let it out real fast about half way and floor it and dump at the same time. I get 1.74 - 1.80 60' with stock clutch. I just installed a MSD with studder box haven't launched it yet with it. Next thursday I'm going to the track. See if I can get in the 1.6 with teh studder box. I build 7psi with it. I don't build any revving it.

sub 2.0 is anything lower than a 2.0...which includes 1.7 and 1.8s, which i think are good 60' times if he got a 2.1 by dumping he obviously had never practiced or his clutch was slipping pretty bad. if you are slipping your awd clutch you are not getting all the potential power to the ground. if you are looking for great 60' times and your clutch is slipping replace it, if you spin your tires with a 6k drop...get stickier tires.

Ive talked to guys at the track who say they slip it and i watched them pull 1.7's all day, ive also talked to guys who say they dump it and i watch them pull 1.7's.
The best ive gotten is 1.9 trying it both ways with an act 2600. What's my problem?

P.S. Watched an 11.7 first gen hit 1.4's with a stutter box...impressive!

 

[eyebrowski]

how hard are you launching it? at the end of last year my friend was able to get a 1.6 60' with a 12.6 ET @ 107mph on his 14b. he has a act2600 and revs and dumps around 6k rpms.

 

[Church]

Normally i just bring it up to like 5-6k rpms and dump it. Ive been trying different things lately due to the fact i can't get better than a 1.9 60.
Does the stock turbo have anything to do with it? Or is it just my driving that sucks? What factors go into my 60ft time?
I have 17 rims with pirelli p7000 supersports. I always get a split second of spin or chirp then she takes off. Would stickier tires and suspension give me that much help, well i know sticker tire can never hurt but what about my stock suspension, is that a restriction?

 

[eyebrowski]

you should be able to get good 60 foots with your 14b. but if you are spinning you are not getting your best possible times. stiffen up the rear suspension andget some stickier tires. the 17s arent helping either but shouldnt be a huge deal.

 

[Black_90TSI]

Well I took my car to the track finally w/ the new clutch. First time up 2.1 60ft second time up 1.9 and my third time 1.83. They got better and better but I had some boost leak issues and wasnt able to run like I planned. Took the car up to 4500-5000 on the 1.83 60' ft so for sure 1.7 next time i go. thanks for the help.

 

[Church]

I got a 2g, running the t-25 not the 14b.

Rev and dump is the worst way to launch an AWD. Its the no-talent way to get good 60's at the cost of your drivetrain.

A buddy of mine used to use the rev 'n dump method. He was sidestepping the clutch at 6000rpm and getting 2.0 60's all day long. Then he broke his 3 bolt rear end.

I have gotten 1.8's with a slow slip from 4.5k and I will be the first to tell you i suck at launching. Slipping is so much faster and easier on the car. The clutch takes a little, but thats what its there for. It takes practice to get a good slip launch, my problem is that i come off the line a few inches before i find the sweet spot where the clutch grabs hard. with practice you can get 1.8's easily. have someone take video of your launches, helped me a ton when i was wondering why my seemingly fast launches were netting low 60's.

Thank you for the backup, also a lot of you guys that are dumping it have small turbos, and dont have a stutter box.

I guess it all depends on mods, and how long you want to drive your car before you break it on the track and piss everyone off when they have to clean up transmission fluid for an hour.

Here's what I have been doing for almost a decade.

ACT 2100: In an AWD car.....I have never, never broken a tranny or rear end with this clutch. In an AWD with 14b, small16g and BPUs it's the best street strip clutch. 6000-7000rpm dump. Easy 1.6-1.7 60ft. Never broken anything in over 6 cars for over 6 years. Hell, just drove Tyler Peppin (Violated_DSM) to a 12.6 at 106.5mph on 14b, and 20miles on new motor with no tuning and 18-19psi of boost. 6500-7000rpm dump hitting 1.70 60ft. Some tire pressure changes and maybe a little lower rpms might get it back into 1.6x as the tires are spinning like mad now with the fresh motor. 2100s don't like to be slipped as they can't hold the heat as well. And a slipping launch is usually accomponied by a slipping 2nd gear.

ACT 2600: In an AWD.....DO NOT DUMP. You are asking to break the center diff or snap a 3-bolt axle. The 2600 is know as a tranny killer for that reason. I have preferred 5000+ quick slip launches. RPMs and slippage vary with track conditions, mods, tires and pressure, etc. It comes down to getting to know your car and it's potential. I have consistantly hit 1.6-1.7x 60ft. on street tires in 14b powered cars. I have have difficulty getting the launch good on big 16g+ cars as they will light the tires up with a high rpm launch. I have been getting low 1.7x 60ft by keeping high revs but slipping the clutch to keep the wheels from spinning so bad in first. But also not to slip for too long as high rpms and slipping heat the clutch very quick. But please don't dump a 2600. You're asking for it.

FWDs.....slippage is the name of the game and it doesn't really matter. You're going to spin anyway. Haha.

first time to try and launch the X with this setup.. i suck!

i have a 95 gsx with lightened stock flywheel and ACT2600 as well.. i cant launch this setup!!. i tried and the first time i bogged like crazy.. and the 2nd time i just ended up burning the clutch.. hella smellin.. and i just gave up and said ill read up ont he boards to get some help..

its hard to find the slip point..a nd the clutch is engaging pretty high.. and once it grabs.. it grabs.. and i just didnt know how to handle it.. i hope i didn't burn my clutch that bad today trying to launch.. wat do you guys think? it was smelling pretty bad .. i was trying out the slip-dump method.. 5k slip and dump as soon as car starts goin..

i guess im just going to have to practice..

 

[Antilles]

Dont worry about the clutch, those 2600's can take a beating like no other. Just keep working on it. My best improvments came after watching video of me launching. Maybe try that.

 

[RedTurboEclipse]

thanks for the reply Antilles.. i felt really bad after smelling the clutch so extensively.. that was the worse launch i have ever done in any car. and thats very unlikely of me.. so i thought i really fugked it up already.. .. but i guess the saying practice makes perfect applies to this..
