Has anyone put their stock 350Z on a dyno to see what the true wheel horse power is? And has anyone weighed their 350Z? I want to find out why the Z's performance numbers seem low compared to Audi S4's. I am aware of the tractional advantages of AWD, but on dry pavement with grippy tires there shouldn't be a 1 second deficit in the 1/4 mile. Maybe the S4 i saw in the clip was either modified or an RS4.

Audi S4 modified ? (http://bsr.abcomet.com/2002/051702/23.wmv)

This thing must have been modified. Factory power/weight doesn't match performance.
