If that thing only makes 532hp, someone did something very wrong.

When I had my 260cfm 906 headed, trw piston, 9.8:1 448 in my car, it went 10.70’s@125+, @3670lbs.
555hp right as it came out of the car.

GY3’s 511 motor should be at least 30-40hp more than my old heap.

What I had was the 5300 converter, 4.56’s, and slicks.

The calculators provide a report card on the “overall” combo, but if that combo isn’t optimized, the hp result is flawed.
