Short answer: The current V7 and V9 models (which share the V35/V50 engine and frame layout) both have comparatively mild engine state-of-tune. The UniBody fuel injection is just one indicator in this regard.
A sporting 1298cc engined automobile that Honda marketed in about 1970 had two versions; the Coupe 7 with a single carburettor (95 bhp), and the Coupe 9 with four carburettors (116 bhp). Note- this was more a "sports styled" remodelling of Honda's earlier 4-door 1300 sedans rather than an outright 'sports' car. Honda's DDAC (Duo Dyna Air Cooling system: dynamic dual air cooling system) in which a double wall structure mimicked the water-jacket of liquid-cooled engines does somewhat bring to mind the twin air-passages passing through the engine barrels each side of the V9's exhaust ports but the Honda employs fan-forced and fan-extracted air cooling. Now, at that time, one would have needed to drive a more-expensive Celica 1600GT, or a rotary-engined Mazda RX2 Coupe, to match the Hondas' performance. But the point here is that by having multiple carburettors among other factors, the Coupe 9's motor produced 21 bhp greater than did the motor in the Coupe 7!
