It fired right up and ran strong the whole day. The carb was just about perfect right out of the box. A/F was 12.35-12.84 the whole run and BSFC was .394-.435. VE was 100%+ from 4800-5800 rpm It made 577HP at 5850 rpm 550TQ at 4800 rpm I has a super flat torque curve. Its making 500+TQ from 3800-6000 rpm!!!! It held peak TQ of 550 from 4800-5200 rpm And its making 500+HP from 4800 rpm on up. It held 570HP+ from 5600-6000 rpm! It is running very clean and very strong. On the street it will sound like a freaking beast, and run like one too. All that torque will plant you back in the seat hard.
