You also need to keep in mind that traction is a major issue on our cars, and the increased torque makes breaking parts in your drivetrain much easier. If you're building a dyno queen you'll be fine but anything you plan to race requires serious consideration in terms of traction and strength.

Agreed. After reading this thread, they're no reason for 600+whp for street use.

12 PSI tune on OEM engine is a protenial low 11's 1/4 mile car all day long.

IMO i'm happy with 8 PSI with 450ishwhp. Can do a John Force in 3 gears, or 1.6 60ft with good tires(and great driver).

Just don't see the point in building a engine other then appying some where other then the street. (Not implying street racing for $$$ just normal use fyi)
