No it probably won't hurt anything, but performace could acctually be worse by adding a pipe.

By adding performace Items you are changing the powerband of the bike.
For example
Stock your bikes powerband maximum power is about 38hp,
You hit that between 5750 and 6000 rpm
With a CVT you want your bike at max HP through the entire shift out for best performance and effenency. Your factory clutching is set to work here and WILL NOT CHANGE by adding power.

Piped your bikes powerband maximum power is about 46.5 hp
You hit that between 6250 and 6500 rpm. But with stock clutching your are still going through shift out between 5750 and 6000 at about 40hp. You lose almost 7 hp due to improper clutching.

Also note engagement.
You will most likely lose some bottom end power with your new pipe.
A piped 400 does not produce more power until ABOUT 5000 RPM
Everything under that you are produceing LESS than stock.
So if you engagement is at the same rpm, then your stock machine will be more powerful until your reach 5000 RPM.

Clutching is probably the MOST important thing over everything else. With out it everything else is a waste.
This is kind of a hard consept to describe, and as I said earlier, get your self the AAEN clutch tuning hand book, it will greatly help you understand how the cvt works.

 

THANX for the help, i really appreciate it.

 

the only bad thing with hpd is they will blow your engine faster cause of the stuff getting in the easier and their design. hotseat is about the best pipe for power you will get and it is really loud

 

What are you basing that info on?

Why would the exhaust effect what gets into the motor?

 

I would definatley go with the HPD pipe if you want performance. Why the heck do you want loud? Loud isn't always better and most of the time it will get you in trouble if you do woods riding or ride where people hate 4wheelers. Does FMF make a pipe for the TB? All there pipes are usually loud and you get no better performance...heck it might even make your quad work worse. Good luck though.

 

i am basing that info my my past experience of rebuilding engines with hpd pipes. i am a dealer of polaris atvs. most of them get things into it through the exuhast port not into the intake. the pipe will give you a 7 horsepower increase and it gives you to top and midrange power. i have a hotseat pipe on my fourwheeler with a hot seat clutch kit and i can play with the 400 and 500s on the flats.

 

LOL. I don't even know where to begin with this kid (BigNig #2)[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img]
