Anyone check out the 2007 XLR-V? $100,000 price tag. Lower compression 4.4L Northstar engine supercharged. 443 HP with 414 ft lbs torque. Engine's bore was reduced from 93 to 91 mm. This took the 4.9L down to 4.4L with a lower compression ratio - from 10.5:1, to 9.0:1.A new ECM was developed, as well. The XLR-V is governed at 155MPH and 173MPH ungoverned.
