Launching is ok but hot lapping definite to avoid is that the consensus here?

I get 7500 rpm lock out on the 1-2 and its super annoying especially when you know the 60 was spot on. So I'd probably love this clutch

 

Hot lapping is hard on lots of components. Any clutch is not going to do well in that scenario especially if you are launching at higher rpm anyway. I suggest giving any car 15 minutes between runs if possible.

 

So a couple weeks ago I took the car to the shop that did the install to make sure the pedal was seated well. We chose not to adjust as they liked where the pedal sat. We did a stationary rev test with the pedal in and the car didn't move an inch. After that I took the car to the strip for Mission Raceway Street Legals.

Best I managed was 12.705@108 with a 1.8 60ft...I know my trap is pretty low. Again...not that powerful and pretty slow given the few mods so my feedback should be taken with a grain of salt for those of you with 400+ ft-lb. Weighed in the car after that pass - 3485 lbs (me - 210 lbs, sub in trunk, no spare or jack and a half tank of gas). Bone stock exhaust is really hindering the top end of the car as I can feel the power die off gradually toward redline despite the fact that the bbk is holding boost (25psi).

Anyway I did 7 passes. First 2 launches were at 5800 rpm and the remaining 5 at 6300 rpm....took it like a champ. Not that I'm making all that much torque (320-330 @ the wheels)...but it never slipped, never gave any problems shifting and the pedal is sitting just where it was before. What's more is I took the car to autocross the very next morning, banging 1st and 2nd all day without any problems, great pedal feel and engagement feedback.

Been driving it on the street since then and it feels great. I can't begin to praise how much easier this clutch is to drive than the Exedy stage II. Pulling off from a stop on a hill is a piece of cake now as opposed to mission impossible before. It engages so well whether I'm in light traffic shifting lazily between 1st, 2nd and 3rd or going full throttle slamming at 7k.

I took video as well...been too lazy to encode and upload but hopefully I get to it soon.

 

Would this be ok for a 2.2L with a HTA3582 for track days? no drag racing, no launches.

If not what would you recommend? CC Twin?

I currently have a ACT HDSS with 18k on it, works great, just thought it should be changed while the car is apart, but maybe not. Thoughts?

 

You had a exedy twin before? What are you shifting at? Where is your pedal engagement point?
After Shawn adjusted my pedal engagement point to be near the floor, the car started locking me out at 8700rpm shifting fast. I adjusted back to where it engaged before and no lock out.

Having driven it with the engagement point near the floor made it much easier to drive.
I am also worried if i use launch control and it takes so long to have my clutch come all the way up, will my rpms shoot to redline before the clutch fully engages?

 

Ordering meow!

Scratch that went sprung cause unsprung isn't available.

 

We have the Unsprung on the shelf? As far as I know we are the only place to get them in fact.

 

It's in eternal back order as I suppose er bought stock / license rights to them?

I went sprung, they(local tuning shop) wholesale from map, extreme psi, and no one can touch it. (Un) No biggie they're just making a name for themselves and I support / help them out where I can .

I ordered from er in the past and I wouldn't hesitate to in the future , do spend local too

 

Performing CPR and took all life saving measures...to bring this thread back from death...
Live d*mn you...LIVE!!!!

So...any update. I'm in the market for a new clutch now. My stocker is toast. I DD my car, has 80k miles on it and the power/mods are in the sig. I've maybe launched like 2-3 times in this Evo (not even a launch, it was just a sad and lame attempt to impress the workers at the local Taco Bell....j/k lol), but I do the occasional highway pulls from the onramp starting at 2nd or 3rd and taking it to 5th, redlining all the way.

So far, the CCI unsprung Stage 2, from what I've read, is very promising. The best bang for the buck in the market (probably after the stock).

So not just the OP, but anyone else that has the sprung and unsprung please share your input.
Don't want to high jack this thread, so PM if need be.
Thanks.

 

I have this clutch and I am not a fan. 1 autocross season and 3 trips to the track with 4 runs each time running around 11:40s-11:50s and it's done for. Slips in 4th and 5th gear. Will not buy again. Going to a act xtss this time around.

My friend also only got one autocross season out of this clutch. After that he went to a act. That clutch has lasted him 3 seasons now and getting ready yo start the 4th

 

Yeah comp ain't gonna last under this kinda power. You'd be lucky to get a week out of it.

 

Clutch swap coming soon and i'm thinking about this clutch..

Currently on Exedy stage 1 and hate the stiff pedal and small engagement window.

I'm currently at 400whp/350wtq with my green, but might move to a Red.

Would this clutch handle 99% street driving with aggressive street starts? Not full blown launching but quick takeoffs with a good amount of slip..

Would like to also be able to launch a few times a year

 

As has been said in this thread a few time, Luke was making 530/530 on it and made 40 passes with a 4.0 final drive. I have a few other cars that dont drag race making over 650 on it but more in the realm of 450 ft lbs.

 

Update: I'm running the stage II unsprung, purchased directly from English Racing. Initially I liked, sh*t I loved this clutch for daily driving and the arbitrary autocross event but it hasn't even been a year, in fact only 7,000 miles and mine is slipping in 3rd, 4th and 5th now.

For reference:

• I drive my car to and from work which is only 10 minutes away. It sees mostly city driving. I'm 30 years old and have been driving stick since 16.
• Since my previous post (Summer 2013) I have been to 1 autocross event (total of eight runs in 1st and 2nd gear each run lasting about 1.5 minutes)
• Launched the car 5 more times. One of them was a bad launch and I slipped the clutch too much, smelt clutch for the next 5 minutes. The car drove fine under full and partial throttle after sitting for half an hour.
• Have not launched the car since (4 months ago)

Last time on the mustang dyno my car made 380whp / 318 lb-ft (September 2013). Since then I fixed an exhaust leak, upgraded to 1100cc FIC injectors and added a sparktech non-cdi cop. It was right after I fixed these issues and put race gas in the car I went to do some logs in 3rd gear but couldn't because it started slipping. Tried once more to get a clean pull - same result at which point I decided it best to not push it further.

I wouldn't expect the increase in power to be a problem given what I read in post #1. My tq is nowehere near the 500 or even 450 mark on a mustang. While the motor itself could in theory be making 450 lb-ft on a bbk full I'm still surprised at the short life span of this clutch. Even with 1 poor launch at this level of torque from the motor - I didn't expect it to be this frail.

I supposed if you daily drive your car and never launch it you may be fine. However, based on my own experience I'd have to advise against this clutch. It seemed too good to be true at $500 bucks and it was. I'll be trying either an Exedy twin HD with an ACT monoloc or the OS Giken R2CD next.

 

Well that's disheartening!
