Time to buy a new clutch for my build as i need to get it balanced with my crank. Aiming for mid to low 500's at the wheels.

Opting for the OS TS2CD, item was originally in the vehicle and felt like OEM item (only had 350hp though). Can only find 1 site with its rating and it says up to 600hp. Have also been recommended the excedy hyper multi (twin plate), or the excedy hyper compe-d.

Im after a clutch feel that wont make my car a bastard of a thing to drive. The OS giken clutch that was originally in the vehicle felt like the OEM item and is why im opting for it this time too.

Your opinions pleas?

Yeah they are good. Being a "c" means it has the larger diameter plates so its power rating will be higher than the b type os twins. Os make great clutches. I've personally owned probably 5 or 6 in various cars all twins or triples and whilst they can be noisy and sometimes a bit grabby they are super reliable and in my experience their power ratings are fairly conservative. So if you'll have 500hp(or did you mean kw?) at the wheels then a 600ps rated os giken should be fine. Personally though if it were my car with a genuine 500hp atw and it was going to be track driven I'd consider a triple as with more surface area they deal with the power and heat really well and hardly wear at all if driven properly. But if you already have the twin and it's in good shape just use that.

Cheers for that Mr Baron.

Ended up ordering a TS2CD the other night off RHD for a pretty cheap price. Had to order another one as this one was KECK. Needed to get balanced with the crank so i kinda needed ASAP. Car will probly not see many (if any) track days. Was really happy with the way it performed before my engine detonated, just wasnt too sure if it could handle my new aimed power figures.

i'm sure you'll be happy mate. they're a good thing. should have just bought the rebuild kit though providing flywheel and cover were ok? comes with new plates, new sandwhich plate and new top plate/pressure plate and bolts. you just retain the original diaphragm, carrier and flywheel. cost around $1000-$1500 depending on model.

    • Not without making up a new screamer pipe from scatch I don't think based upon the angles of the current return. Backpressure shouldn't be an issue though as the straight gate isn't affected by backpressure in the same way that a poppet valve is, and on top of that the exhast system is 4" all the way through so there should be minimal pressure if any to begin with.
    • Can you vent the straight gate to atmosphere easily for testing?  
    • Heres a dyno log comparing MAP TPS RPM TURBO SPEED Each hump is 2nd, then 3rd then 4th gear. This particular log is using gate pressure with the mac valve completely removed. As you can see it spikes to 23psi, and then drops to 20psi over the course of approx 700rpm, this is the minimum pressure the system will run using a 12psi spring. I think my next set of logs will be changing the spring to the 6psi spring and going out and doing another set of logs again and see if the spike is as dramatic. As you can imagine if it spikes 3psi on wastegate pressure, that increases to 5-6psi of difference in the higher boost levels approaching the 28psi target with the mac valve. I even have a few logs here where with the mac valve targetting 28psi, the haltech is seeing 38.6psi.... 
    • I've got a spare standard box sitting in the garage  I know it will come one day though, but it's driven pretty tamely on the four times a year it gets out... 
    • Big question… have you decided on a gearbox? Because it’s going to come… and a gearset ain’t going to do the job.    save your pennies 🤪
