Is Fcr any good? What about edle brock? How much extra power do you guys think it will give?

 

FCR gives the most top end power...which I'd assume you'd want since you are on NOS.

How much power will you get?...- How good are you at jetting? You don't have enough motor mods really to see the full benefit of the carb, but go for it if you want.

 

So basiclly if i dont go bigbore i dont need it.

 

you get a good benefit from the carb as long as you can get enough air in which canbe difficult to do, but granted it works better the more mods you have.

 

How do you like your 400. Is it fast, and can it hang with the four strokes. Also can u use the fourwheel drive when you have paddles?

 

mine is a 2 wheel drive scrambler my brothe in laws Z has a full pipe, cdi box, 12.5:1 piston, intake cam, fcr carb, cutom intake, and hes a good rider and i still take him by about 4 lengths in the sand.

 

yah thats pretty nutz.....frickin scrablers gotta fly!.......I remeber discussin that polaris 400 motor with u before, when i didnt know much about it! Gettin air in is a prob, but so is gettin it out, if you dont have a big bore.... Porting i know helps! you will literally about have to run and will benefit most from using NO AIRBOX! and just the huge ProFlow K&N!

I am curious about this also!....i will be running a UM Performance 400EX airbox....ProFlow Filter, and the 400ex Carb Boot....it all fits, and is much larger then the Z400's stock setup is! I have seen this done on several dynoed machines and it proves to be beneficial!

i talked to arlan lehman (very very knowledgable) of lrd quite a bit down at dunefest, he has been building intakes similar to what we made on our Z for his Z's and both 450's they flow better than any airbox.

 

Im hit there, because i HAVE to run an airbox! GNCC Racing and u know the trails get nasty LOL!

yeah i guess your out of luck there but your set up should still flow very well.
