im looking to go around 420whp low boost and when build around 550whp high boost....

which clutch is better Exedy hyper single or Spec stage 4???

 

Exedy hyper single.

Exedy is working on a multi disc pack, hopefully it is done soon, it has been in development for 6+ months. PM us if intereted.

Honestly with that much power you may want to consider a twin disc setup.

 

exedy is releasing their new twin disc very, very soon. contact OTT

 

Give it a couple months and there should be another clutch on the market.

 

yeah im waiting on exedy to come out with a clutch that can handle around 550 to 600 aswell then ill purchase a clutch and flywheel.

 

Exedy hyper single is around $1080, expect the multi disc pack to be around $1500

 

thats crazy expensive.

 

Ha you think thats expensive you should look into a replacement factory clutch thats only good for 350ishwtq lol.

 

factory clutch starts to slip around 320

 

what about clutch masters????

 

i understand that exedy multi disk will be expensive.... but ive had a lot of their clutches and they work extremely well.

 

mine doesn't im at about 340 and -20 -30 degree weather, no slip at all.

everything factory costs ur arm and ur ...well pretty much all of u. lol

 

The performance and cost of the exody makes it look like a bargain LOL

 

I rode in a SS with a stage 4 clutch masters and it was light a light switch, on or off... engaged or disengaged. The owner said he loved the clutch and it held the power very well but I'm not sure how high it's rated for hp/tq.

 

Priced just a factory flywheel, 850.00

 

Not unless you got a defective one. The least wrtq I have ever seen a stock clutch slip on was 360 wrtrq. Mine started slipping at ~380 wtrq.

 

^Agreed. 350-360wtq on the dyno was where ive seen a few cars start to slip too.

 

For your cobalt?

I bought one from my dealer a few months ago for like $120

 

That doesnt seem right....that is an insane price

 

Just installed a spec 3+ on the sky. Doing the breakin now. But feels amazingly like stock. Holds up to 688 crank tq. Got it for 1k with the flywheel. Full faced also. Makes for super smooth engagements.

 

688 cranked torque?!?!?!??!?!?! shiiiiiit how about hp?

 

clutches are rated for tq, not hp

 

dam thats good... good **** im geting thatone then....
