Hi everyone,
I just purchased a regal 2200 which is powered by a volvo 5.7 Gi which is now a 300 hp
I was just wondering what volvo has changed to upgrade this engine from a 280hp, to now a 300 hp ? As of January, these engines are now 300 hp

thankyou for all your help,

 

i bet is the exhaust manifolds

 

interesting, so by changing the exhaust manifolds, it can generate another 20 hp? so now would it be similar to the merc 350 mag 300 hp?
