you're running boost through a stock clutch?? Wow. The limitations of a stock clutch are not much higher than stock. A set of sticky tires on an otherwise stock clutch shouldn't have much of a problem blowing up the clutch. FYI, the king cobra clutch is rated 30% over stock, or around 300ish flywheel horse. If that tells you anything, you're running on borrowed time, as the stock clutch is well under 300 horse.
