Hi Korryy, if you mean 300bhp is enough to cause the Q2 to be able to spin wheels in a drag race I'm sure it is, although its easier to spin it up under cornering. Its still a big improvement over standard though.
But If you were worried about the strength of the Q2 diff it does appear to be very strong, and is running ok in cars approaching 400bhp.
Regards,
TB
