Ogura orc1000f vs Osg tr2cd vs Osg r3c experiences, max torque/max hp?

[CefiroA31]

Hi all, considering clutch upgrade to support 1130 engine hp from 1650cc injectors on e50 at 85% duty cycle (1650 x (11.85/14.7) x 85%). Narrows down to these three as they can be converted to use gm 26 spline input shaft if I ever want to use transmission with that input shaft (orc1000f and r3c easy/cheap just change center hub; tr2cd pricier must change clutch discs).

Pricing orc1000f similar to tr2cd, r3c about usd 200 pricier.

Orc1000f triple plate 200mm.

Tr2cd twin plate 215mm.

R3c triple plate 215mm.

Claimed max torque : orc 1000f 723 lbs ft; tr2cd 800 lbs ft; r3c 1100 lbs ft.

Why orc1000f triple plate but claims lower max torque vs tr2cd twins? Is orc1000f underrated? Any info maxing out these clutches? Info on street/traffic driveability/pedal feel?

Thank you for any info on them.

Hi, this was in the suspension and braking section. I have moved to more appropriate area.

I have the OS Giken R3C with the GM 26 spline input shaft in my 32(Rb32 with only around 750hp atw) and its a pig to drive. Its actually very forgiving when its cold when when its warmed up, it chirps the tires even when trying to take off slowly. Mind you though, part of this has to do with my clutch master(Non-OEM) so the travel on the rod is shorter. How did you get 1130hp at 85% @e50?! Are you running a stroker? If so, I would recommend the R3C purely because it handles the abuse.

I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.

Haha I do that.. thats when it chirps..The bit point for me is almost non-existent. Otherwise I stall it. But yes, in terms of performance, the clutch is solid af.

I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as
