Stock clutch limit
Anyone have experience on how much the stock clutch will hold? I bought my 05 Evo GSR last year 100% bone stock and when I put it on the dyno it put down 258whp and 257wtq. My tuner said it might have a mild tune on it because my AFR was slightly leaner (11.5 I believe he said) than most stock VIII's run apparently. Anyways, since then I've done my full turbo back (Map DP w/wastegate dump) including tubular manifold and test pipe. Recently installed my guages and I'm peaking 23psi and holding 20psi steady, however I'm holding at 12.3 AFR ( I know I need a tune), which is more lean than I want. Now, my clutch doesn't slip AT ALL. But The few times (and I do mean few) I've launched it, I smell clutch no matter how fast or slow I let out. Obviously I'm done launching at this point, but how much more power will it hold? I plan on doing my front mount and piping, BOV (it will not go on until the day I'm driving to the tuner), fuel pump, then getting a tune and calling it quits for a while. Just curious how long it will hold up until I can get a new one.
Not a bad line for stock (at the time)?

As long as your not launching your car it will hold up. After getting some bolt ons on my car the first time and my power was 325 whp/ 319 wtrq on a dyno-jet I would have the same issue on launches. I would get a tune if I were you because those 12 afr's are just a little lean.

Sweet cause I really don't want to buy a clutch right now. My ACD needs servicing at the moment lol. I know I definitely need one, but I really don't wanna pay $300 for a tune right now, just to get a another one in a few months. She is lean, but she runs perfectly fine. Thanks for the info man.

I have seen a few guys running well into the 11's on the stock clutch. They don't last long drag racing but if treated gently for launches, they could live on the street for some time.
