Standard driveline loss is around 18%
Therefore multiply by 1.22 to find crank HP from wheel HP
Standard SVT makes roughly 165HP
Those were the numbers I was using.
If the other SVT's were putting out 151-155HP then either the dyno is out of calibration, the temp & humidity were 100+ or some people should be really pissed!!!
2 SVT's here in KC put down 172/160 & 178/154 with a home brewed (stock piping - diff mufflers) and Bassani exhaust respectively... Most others are 160's HP with 150TQ range. Others I've seen (other dyno's plots online) are in that same range.
But then again - different dyno's are hard to compare off of...
