Dyno day with the NWQuattro Club

197 whp  270 ftlbs




 
Got a 217 on my first run but they did not have my car tied down well, so the chart had bounces in it.

Congrats. Nice to see a person put a car on the dyno to get real numbers.

What is the general accepted driveline lose, I thought it was about 16%

That would put you at about 230hp and 313lbs of torque. I really wish they could have started the dyno at a lower RPM to show off the low end grunt of the 4.9 I have been told it makes within 10% of max torque down at 2000rpm.
