I am at 336whp/341wtq on stock trans. Pulling it this weekend to put in my 6spd, but nothing broken. Been at over 300whp for about 60k miles and still on stock clutch
I was running the stock 5mt for a couple of months with 450 wtq and 450 whp. Never did run it at the strip with that much power but I did run it for a year with 390wtq 350whp. I had about 50 low - mid 12 second passes with that set up.
