I'm working on making 600/600 hp/tq and I believe I'll need to swap the stocker out ASAP. So, with that said, what's everyone running for the 500+rwhp level? I was thinking about the spec 3 with an aluminum fly so it'll rev faster, but I'm open to suggestions.

what do you have? where did you get it? Any complaints? etc... :

Lets hear it!

 

def. wouldnt recommend SPEC. im having problems with mine right now. so is my buddy steve (fixedroof.) check out LS1tech for multiple SPEC issues.

we are now looking into the RAM HD. its def. in your price range, and we havent read anything bad about them.

i would like something like textralia, but cant justify spending that money.

 

I actually received an email from someone selling the textrilla clutches on ebay. Jeff, if I recall correctly.

Wasn't there a good bit of controversy over Tex. clutches a while back? not with quality, but of remanufacturer or "fake" units?

 

How much is the cartek setup?


I was debating cartek or spec 3i.. and I think I am going to go cartek.

i was going to go with a setup from JEFF on ebay. he is the president of the company. i called him, and the whole thing is messed up. he was going to give me an AMAZING price on their kit. i believe his story, but im not going to take any chances. its really a shame.

 

Do yourself a favor - DON'T get a Spec 3 clutch. Too many bad reports of quality and noise from forum members. Also, don't go the cheap route if you really plan to put down that much power. It didn't take long for the LUK Gold Stage 2 clutch to die on me. The RPS clutch is strong, has stock-like pedal pressure and doesn't make a lot of noise like most performance clutches - but they're not cheap. When it comes to the saying, "You get what you pay for" - Clutches definitely fall into that category. Good luck

 

here's an odd question:

how long is my stocker going to take the abuse? It's not slipping at all at ~400rwhp and I shift fairly hard. So, will it take easy shifts and full-throttle roll ons with 500/500 rw? If so, I'll have it dyno'd with the stock clutch and make a decision after that.

 

It really depends on how you plan to drive your vette - daily driving vs. road racing vs. drag racing. While the shifting in road racing (HPDE/TT events) is not as hard in terms of high RPM "launches", you do shift a lot (up and down) on the track at high RPMs. You're on borrowed time with a stocker. You should be fine if you drive your vette primarily as a daily driver and don't launch hard with the 500/500 setup. EDIT: WKMCD made a good recommendation re: LS7 clutch kit - I forgot about that option.

 

Not sure about 500 RWHP but I'm running an LS7 setup with about 470. Works great and is ~ $530

 

I am leaning towards the LS7 myself. I have 530rwtq, and only go to the track a few times a year, so something that I can live with everyday is better for me.

LS7 is unproven. we have seen posts of it in cars for about a month now. lets see what happens to that clutch after 1 year.

we know how cheap GM is with their clutches. clutches sucked in the LT1s, sucked in LS1's, still sucked in LS6's... so what makes everyone think its going to change with the LS7?? just my thoughts, i say hold off on the LS7.

a year ago everyone says get the LS6 "Z06" clutch. now look what everyone says about it. its a stock clutch, that doesnt hold power, and even develops the "sticky pedal" on STOCK cars!!!!

 

I had a spec 3+ and it lasted all of 5k miles And then was toast. I have heard quite a bit of horror stories about the spec3 and how they would blow up. And I do mean blow up right threw the dash and out the front windshied . I end up going with a Cartek and sofar very happy i did. They are rated up to 700 rwhp and still have a pertty nice feel to them (almost stock feeling) Plus the cartek comes with the adjustable slave . I also heard the ls7 clutch is good to but a few people are still having the clutch pedal sticking on the floor.
BTW I putten out 473 rwhp 489 rwtq

 

where did you buy your ls7 set up for 530, for the clutch, flywheel, t/o bearing, slave its almost 700 before shipping?

 

i am running a spec stage 3 + clutch.. with the billet flywheel... im pushing over 500 to the wheels with my 408 with GOBS of torque.. so far it has not even thought about slipping for a second.. hold STRONG and engages AWESOME..




in specs defense... people were being retarded with their clutches.. the clutches are rated at RWTQ and people were maxing them out and dumping the clutch with RPM's and tons of torque... BUT spec did have aproblem with teh clutches EXPLODING and taking out all sorts of stuff.. .including headers/footwells/windshields... totally exploding...



supposedly they have fixed it all with the new stage 3+ clutch... i was assured by all the vendors i talked to that the stage 3+ when broken in correctly would be an awesome clutch. and that they had very good reviews on it...



clutches for these cars is a very tricky process... EVERY clutch maker out there has had horrror stories with LSX cars... and i mean EVERY clutch...


exedy twins that glaze and last 2 passes
Rams that last 1k miles
specs that explode....
textralias and the whole "fake clutches" crap.


there are problems with them all... its pretty much hit or miss...



but for the record.. i LOVE my spec stage 3 +.... you HAVE to make sure you get the newer model though.. so you dont get stuck with an older "exploding" clutch..

 

Have the LS7 and have 450 rwhp and 500 rwtq. Have had it for only a week. I like it but like i said it is only for a week. Plus i don't race the car so i am probably not your best example out there.

 

will be removing my "NEW" spec 3+ next weekend. nothing but problems. buddy steve is removing his "NEW" stage 3 also, we are both pretty dissapointed with the company.

now that ive done the research (should have done more before) i would have NEVER installed a SPEC. too much negative feedback. for every 1 person who says they like it, 5 reply with problems.

i do agree with you though, all companies have had their problems with the LSx cars. really sucks! wish this wasnt so difficult!
