Spec stage 3+ bites the dust
I bought their most expensive cluch for my car, but not the highest capacity one from MAP last spring sometime. It has been really nice to drive on, the pedal feel is lighter than stock for the most part, and it held up to 417-420 pounds of torque all summer. But it would not hold 460 pounds last night, and refused to try again. So I had to head home sadly. I was about to test and compare against some evo and a honda, lol.
I emailed spec and told them what happened, so I am looking forward to their response. I don't want to have to use a solid hub clutch, but their stage 5 is the only upgrade in capacity and it goes up to 610tq.
Derek did some quick math and 15% of the 525 tq rating would be about 450 at the wheels, so I'm over that by about 10 at this point. I would have thought it could go well above it's rated capacity. My ACT was rated at 330tq and held 390 at the wheels.
This brings up another question, which is how far do I want to chase this rabbit down the hole? There are better trannies out there, and this one is questionable as to how much more it would take before giving up the ghost, and possibly taking someone's leg with it.
