Reply #13: The 917/30 had 1100 hp (1500 @max boost), did 0-100 in 2.8 secs, 0-200 in 3.9 seconds [View All]

Now, that's torque - 880 ft/lbs. Note the acceleration is faster from 100-200 mph. The first 0-100 mph is very much limited by available traction, even with 20 inch wide tires.

Here's some comparative stats between the 917/30 and the more modern Audi R8 LeMans
