My car made a clean 450 rwhp @ 13 psi boost, like 420 torque also (no meth) and would have been a fun driver. Because the engine was so new we stepped it back to the 360 range at 8psi and it would still break the tires loose in 2nd gear, my problem came when we added meth, made 412 @ 10 psi and TUNED the car for meth, my intercooler was also a bit small. As long as you keep the IAT's in range I think you could run around with 450 rear wheel all day long, especially a supercharged car that has a lower torque curve.
That is respectable and realistic power, from a V6.
