I have a 99 scrambler 400 4x4 and I put an aaen pipe, and boysen reeds in it. Now it really rips!! I am putting 20x11x10 Razr's on douglas wide offset .190 Alum rims on the back and 21x7x10 Razr's on Douglas wide offset .190 Alum rims on the front. I am also getting it bored and stroked,works shox on it and an extended swingarm!!!

MAN, I was just wondering this yesterday but didn't get to post it!!!! I was curious about that myself, since my stock Tblazer has 21hp, how much is getting to the dirt? I know the chain don't soak up the power like a shaft drive, but what about the pvt? Anyone ever dyno a quad for rear wheel power? How much is lost from the motor? Any help is appreciated....

For Polaris machines the key is to know how to clutch them. There is no specific kit you can buy to get X amount to the ground. It's all trial and error! Remember though that every additional mod you make that effects RPM's usually will require a slight adjustment. I would look into a roller clutch from HPD or AAEN.

Nothing affects getting hp to the rear wheels on a Polaris as much as clutching. But first you need to make hp to get it there since these systems are torque sensing. . Low hp / low torque machines do not respond well to clutching changes as well as those that have mega hp. You need to build the motor and then get the clutching to suite your own riding style.

Actually you should do your hp and clutching changes at the same time to get the best performance. Also Polaris states that the engines peak power is at 6800 rpm. even if you change hp & clutchs anything higher will result in damage!
Speaking from experience!!!!! Also you will need to make suspension changes as stated above. All the power in the world will do you no good if you can't get traction to make good use of the power
