[jasoncarr25]

THAT FAR FROM SUCKS, YOUR NEW 450 QUADS ARE ONLY PUSHIN 36 OR 38. SURE BEATS SPENDING ANOTHER 7,500 ON A NEW QUAD. MINE IS ALMOST PAID FOR.

if i remember right CT 440s put out around 40hp. but i did read somewhere that they make 45rwhp.

[300expower]

i thought that too, its very sad, but i could pull out easily yammis 450, who take out 47hp when jetted on dyno, and take out a few 727 in 400foots...:devil:

[jasoncarr25]

I THINK DUNCANS NATIONAL KIT GETS 48HP

That number may not be a good indication of a properly built 440's potential if that Wiseco "11:1" piston wasn't set up correctly and it's really about 9.7:1.
