Brand new motor
Hi-Tech You have a brand new motor that is just Dynoed and has breakin time. Everything is still tight. But a couple of thousand miles on it first, then get a performance check done on a chassic dyno. KC Is keeping the motor a little rich in the beginning, all builders do this. It protects the motor. After breakin, about 5,000 miles then you can lean on it and up the A/F to 12.5-12.7 for max torque or 12.8-13.2 for max HP. Every motor is different and responses to different timing and jetting. Your side pipes are also costing you from 15- 40 HP with back pressure depending on who built the pipes and what mufflers are inside the cases. The numbers are fine, just respect the car and happy miles. Rick L. one side note you might want to put ear plugs in before the drives.:rolleyes:%/ side pipes are loud and drone. The main problem is getting the smile off your face.:eek:;):):LOL::LOL::LOL:
