a 250 engine can in theory put down more hp. it is easier for it because the engine can safely rev to a higher rpm. this is where the hp calculation with torq cross each other at 5250 rpm on any dyno sheet. if you can hold 300 ft lbs of tq at 5250 then you will have 300 hp too. keep holding the tq and the hp will climb.
my engine is very streetable, drove recently 128 miles each direction for our inliner picnic. never a glitch. drive it to work occasionally also. atleast 60 miles each way.
243 hp to the tires is apprx 300hp at engine, considering the drivetrain losses.
so in short 300 hp is not hard on a engine, even a 250. turboed of course. with a n/a engine that is a whole different animal. not really streetable , atleast not like i drive. tom
