which big bore kit will give me 50 hp at the wheels. whats the price or where can i find it?? and it must be a 450 or under im going to use it to race. thanks

 

maybe the athena 440 but i doubt it lol

 

50 is an extremely tall order.... for a 4 stroke

 

at the wheels? no! the 440 kit out of rocky mountain isnt going to do to much. ive heard a high comp piston ,like a hammer headz and cams and bigger carb will open that baby up . but just the kit ,no

 

maybe with a good port job with all of the mods, swich fuels and ceramic coat all of the componates, with a 440 and my porting , coatins yes it can be reached gassrx.com

 

with everything I did to mine when I had the 440 kit the most I got was 44hp at the wheels
the only thing different now is its a 470 . with all the same mods done to it.
its possible to get close but I wouldnt count on it

 

i checked out trinity and they claim their kit will give you 50 hp to the wheels, trinityracing.com. but i was just wondering if there was anything else.
