One thing that I have noticed about carbon discs is a lot of material failures. That means you have to accept clutch rebuilds as a normal thing it seems. I don't know if vendors like that idea since we have some real complainers out there about "race parts," (like people wanting "soft" solid motor mounts). I am saying that based on the heavy use of RPS twin disc carbon clutches in 3000gt's.
I would think simply putting on new pucks should not cost too much as long as we avoid markup.
Maybe TU or FWD would be willing to try sourcing something. I would probably like to own 2 discs, one for use and one as backup in that situation. I honestly love my solid hub for driving but I think it kills parts. Carbonetic still seems to use sprung hubs which are not our friend at high rpms.
Well 7.0:1 compression and more methanol then gasoline doesn't really count as pump gas haha. I still question the reliance on that much methanol because I don't truest the systems. Evos make 600 sometimes on 2/3 the displacement on true pump gas with smaller turbos!
I do think that JT on pure pump gas would save axles cause he would slow down. I also wonder how scared guys are to bog a little and save those axles. 2500 rpm launch control, etc. I am willing to bog a bit. I don't think its HP thats breaking anything for me, it was shockloading from a heavy rotating assembly at high rpms.
I have not made a pass on slicks in 3 years but I would like to start low and see how little RPM I could get away with and not completely destroy the 60' The problem with that is that as far as repeatability goes, you would need to use the same clutch technique each time etc. Heck, maybe low rpm launches with a lot of clutch slip could get near the same 60'. As long as your turbo is not too slow to come on.
Well if it was worth researching the stock size, why not the larger size. I don't know how much stronger that shaft would be but with how easy JT is breaking axles and my assumption that he is not actually going all out, a small increase in strength might just last a little longer, or still break on the first bad launch.
