Since I have a 4sp tranny, I wanted a car that is good around town and in traffic. I also wanted a car that would haul ass off the line without twin or bi-turbo's. Since I switched away from CIS to twin plug, 8.0:1CR and stroker crank, I promise you I have a car that performs like a NA car around town. I have an electronic solenoid controlling max boost, but every once in a while, I switch programs from .8 bar to 1.0 bar to open it up. At 18 degrees total timing, 11.8 AFR and twin CDI plugs, the motor can handle the pressure.

Speaking of bi-turbo's, I helped my neighbor install a hybrid bi-turbo (a huge turbo feeding a very big one) system on his race Dodge pick-up - it has a 12 valve Cummins diesel that handles 100 psi and mid 10's on 1/4 mile. Wholly crap - 6.8bar at 2500 rpm (6000 red lie) and nearly 800 hp and 1200 ft lbs of torque (or somewhere's there about..)
