Why do some V8 cars have more horsepower than other V8 cars?

Question

For example, a V8 Bi-Turbo G63 AMG has 577 BHP and a Twin-Turbo V8 Koeniggsegg has 1160 BHP. How do virtually the same engines have such a large discrepancy?

Answer 1

V8 only tells you how the cylinders are oriented. it doesn’t tell you displacement, flow characteristics, stroke bore ratio, etc etc. and as both a turbo’d, V8 doesn’t tell you how much boost they’re running the turbo’s at. the G63 run s 17.4 psi boost. the Koeniggsegg runs 24.7 to 31.9 psi. the G63 is a 4.0L. Koeniggsegg runs a 5.0L
