broke Posted June 3, 2005 Report Share Posted June 3, 2005 50ish depending on port work. Porting will make "ALL" the difference in the world, so it's hard to say. I always say my motors have 60HP. No matter what I build it will always be 60hp. Don't get too wrapped up in the numbers or pretty dyno charts. Dynos do one thing well, compare. As far as the number goes, who cares. But they will tell you if one pipe will out pull another on a given engine, or where the jetting needs to be tuned in a little more. Quote Link to comment Share on other sites More sharing options...
rocketboy Posted June 3, 2005 Report Share Posted June 3, 2005 if you plan to have passion porting, why dont you consult with jim (passion re) on here about his designs and what he recommends and estamates? Quote Link to comment Share on other sites More sharing options...
race-a-holic Posted June 4, 2005 Report Share Posted June 4, 2005 if you plan to have passion porting, why dont you consult with jim (passion re) on hereabout his designs and what he recommends and estamates? 377382[/snapback] It's important to get a builder you can trust.I've never used passion,but have heard good things about him.You should tell him what you plan on doing with your banshee,and he should have some suggestions.He'll most likely have a pipe he prefers.If you mostly ride trails,then you don't need a drag port.

Quadracer593 Posted June 4, 2005 Report Share Posted June 4, 2005 Banshees have 48 HP Stock so what stuff would probably get you to 55 or so? not sure Quote Link to comment Share on other sites More sharing options...
Banshee~ Posted June 4, 2005 Report Share Posted June 4, 2005 Banshees have 48 HP Stock so what stuff would probably get you to 55 or so? not sure 377498[/snapback] No, they have around 32-35 stock. The best thing you can do is call your engine builder up and tell him what your wanting out of your engine and he will hook you up with carbs, pipes, ect.

wesw Posted June 4, 2005 Report Share Posted June 4, 2005 jim has software that roughly tell him what the motor specs will make. he will give a pretty close estimate. it varies with the pipes from one to the other. just ask him. he is a nice guy and will answer your ?

Like Banshee~ said, they are more like the mid 30's. Quote Link to comment Share on other sites More sharing options...

Like Banshee~ said, they are more like the mid 30's. 377621[/snapback] Not to take a stand one way or the other. The new issue of dirt wheels has the test of the first banshee and states it has 48 hp. Quote Link to comment Share on other sites More sharing options...

Is that the magazine that said the 400ex was faster than the banshee when it first came out? Quote Link to comment Share on other sites More sharing options...
