[QUOTE="JimIII@jdm, post: 15673371, member: 10902"] No, people do it all the time. We are leaving a limiter at 6800 RPM which is pretty reasonable. It's more than RPM that breaks stock rods, torque, load, boost, detonation...etc all play a roll. This car is running about 16 psi boost (moderate compared to some), has only 16 degrees timing, and the cams are helping to relieve some of the internal pressure as well. It breaths very efficiently so there is not as much stress on the motor. Now if he was whacking it past 7,000 RPM on a daily basis that's a different story. Also a pulley that adds 2 psi boost is not going to gain anywhere near the power of cams. You're also cramming more heat and pressure into the motor which would be more stressful in my opinion.
