wat would i have to do to get about 27-30 hp from my 300ex..i no it makes 23 stock..this is not including a big bore kit ......and how much hp would it make wit a 380 big bore or a 405:eek2: strocker kit

[sled_ed 300ex]

A 300ex only makes about 13 hp!!!:D If you want 20some horses
just put a 400ex motor!!!

[300ex_rider1121]

it makes 23

[300ex_rider1121]

well like 19-23 it depends on the dyno

[sled_ed 300ex]

big red=7-8
300ex=13
400ex=27

Sorry but the 300ex only has 13 hp at the rear wheels. The only way to get it up to 30hp would be to put the FST 400 stroker/big bore kit

i would say a 352cc stroker would get you around 30-32hp thats with port work and valves, carb, cam, pipe.. but yes the 300ex only has around 15 hp stock

300ex_rider1121 is right the 300ex makes 22 to 23 HP atleast thats what honda says right off of the showroom floor. Look at your certificate of orgin (title) it says it right on there. It may not be 23 at the rear wheels but thats what the engine puts out.

I rest my casse!!:ermm:

a stock 300ex makes around 15 at the rear wheels on a dyno, it MAY be 22/23 at the crank, but idk about that either
