Re: you
I get 80FtLbs with HD slip on mufflers, K&N filter (HD kit) and Dynojet kit(also in HD's product list).
Why does the Merch motor makes so much power? It is a 120" motor. It is the same engine HD designed in the 80's Merch used the best parts they could find, and flowed the heads. Same HD design.
I would like to find out more about the 4000fpm piston speed data you talk about. It makes sence, I just want to know more about it.
I found info about how related HP and Torqe are at:
http://www.howstuffworks.com/horsepower.htm
It reads:
You can easily convert torque to horsepower by multiplying torque by RPMs / 5252.
You guys are so smart!
I was wrong, they are related.
