400EX dyno run

As you might imagine, the 400EX will run faster than 47mph - but that's where it's HP peaks in this dyno run vs stock gearing. Your theory doesn't hold up. Top speed is a function of available HP at a particular RPM range (due to gearing) and aero drag.

Keep in mind that the Scrambler runs out of power to overcome aerodynamic drag at approx 70mph as it has "infinite" gearing. The 400EX runs out of gear (not power) at top speed & can be geared up to run well in excess of 70mph stock (with a corresponding decrease in torque multiplication at the rear tires - which would affect everyday riding).

Although given your credentials maybe I should put more faith in your comments over this dyno operator and race engine builder.

 

how dare you even use scrambler in the same sentence as RAPTOR!!!!! I wouldn't even compare a srcambler to a 300EX!!!! face it polaris quads are NOT competitive!

 

Good post 86atc250r...the link for the Scrambler rear wheel HP seems more in line with the performance of the machine.

 

Gabe,
While I see your point in comparing rear wheel HP to crank HP I've been told it's hard to get a good estimate of rear wheel HP on an CVT tranny. Also the reason a stock 400EX may be a tad faster than a stock Scrambler is weight. (And a VERY tame CVT setting from the factory) If one were able to just swap engines & trannys from the light framed Honda to the Heavier Polaris the outcome would be way different. The 400L is twice the motor the 400 Honda is. In fact HP wise I would put the 400L & it's potential against any quad motor made (yes even the Banshee). How many motors are capable of 60 RELIABLE HP????
There is no question Polaris motors have the HP, it's a matter of weight, heavy frame design & medicore at best front suspension. If Polaris wants to make a quad to whip everyone a$$ they will. That would be tough to handle for some people. The fastest quad made an auto!
To tell you the truth I wouldn't be surprised to see Artic Cat make the new king of sport/race quads sometime.
As far as the Raptor being the greatest quad ever I just don't know. Yamahas own ad says it devours the competition. Then it loses to Banshees & DS's. That's false advertisement isn't it?
One other thing. While I do find the axle bending thing on the Raptor really sad on Yamaha's part, some people should lay off some of the Raptors other problems. Yamaha took a chance with a new quad and alot of new peices & sure they are going to have bugs to work out. Honda's are reliable because they aren't changed much. I'd rather have change & a few issues than have the same old thing.

 

Polaris beat a Yamaha.... One word... NOPE!

 

TIMEWASS, I from up the road in Portage, maybe sometime we can go riding

01 raptor

 

Don't you like your scram?
If you do, why do you try to convince everyone that the Craptor is not what Yamaha says it is? Someone said it puts out 60hp. He's wrong. So? My banshee puts out 70hp. Are you gonna get mad because I said something wrong? Just forget it and RIDE.
BTW, the biggest problem with the scrambler seems more to be the chassis (especially front shocks) than the engine (my opinion though).

 

Andrew, you're wasting your breath trying to explain the 400L to most of these guys. I'm sure there are more than a few of us who have seen a 550lb. Scrambler occasionally outrun a Banshee. Look at the post after yours, typical uninformed response. Those of us who know better know what a 375lb. quad with a piped 400L and a tuned clutch would do to everything else out there. As far as that goes, could you imagine a 400ex against a 375lb. Scrambler 500? Its just a shame Polaris won't do it.

 

Yes, but it's also a shame Honda won't make a new aluminum chassis'd TRX250R or TRX500R based on current production engines - or Yamaha a YZF426 quad w/250R geometry, etc, etc, etc... Get the point? We can hope and wish all we want. Point is, the quads we are talking about are available. There's no sense in speculating what a 375lbs Polaris would do, because they don't exist, just like the other quads I mentioned.

Sorry for the rant, but if you are going to condemn us, at least have a valid argument.

 

I get the point just fine, you don't seem to. All I'm asking for is a lightweight frame to bring the weight down. Honda, Yamaha and Suzuki have been putting out quads that weigh less than 400lbs. for years. I'm not asking for anything exotic like an aluminum chassis or some imaginary quad that doesn't even exist, all I want is a lightweight framed Scrambler. Look at the new quads Hotseat is going to produce, they will probably weigh under 400 and they will use the auto transmission and make over 100HP using Polaris engines. What I want could easily be done, in fact I could buy the frame right now, but it costs $5000 and I don't want to prove my point that bad. I will stand by my argument that if the weight were equal, a powerful 2-stroke with an auto transmission would be very hard to beat in a drag-race.
That's more validity than you need.
