It was essential to baseline Blue Thunder prior to the installation, which the crew down at SLP graciously offered to take on. My previous trip here resulted in 237hp and 305 lb.-ft. of torque at the wheels, but the last dyno BT visited said it made 221/285. Back on the SLP SuperFlow once again, Blue turned up 222.3hp and 289.3 lb.-ft. Where the power went I'm not sure, but a leakdown test at the time of the valve spring install said it wasn't sneaking past the piston rings.
