Thanks cc1999, very insightful. I've finally met someone that goes through quads like I do! LOL

 

Hey cam, do ever ride at the dunes (little sahara). I was thinking between the quads you have and the ones I have we could meet at the dunes sometime and have a little shootout of our own to campare. I have raced a BF750 down there but it was running 27" mudlite and even my buddy's stock twin peaks killed it. If your quads are close to stock we could get some good info from it.

 

if you raced in sand cc1999 the bighorns do much better than stocks on the poo

 

Why would you say that, they are heavy and from my experince they are not that great in the sand, If anything I thought they were giving a little help to the Polaris. The twin peaks runs a heack of alot stronger with its stockers on than the Bighorns. It gives up about 3 quad lengths runing the bighorns vs the stocker OEM tires and wheels. Since My P650 is less than 1hp off from my buddy's Twin peaks we have done alot of different tire and wheel testing at the dunes and the Bighorns are a real handycap.

 

Boy I got to tell you cc1999, I don't think that a race in sand is a reasonable way to compare two big bores unless you are specifically concerned with how they perform in sand. The reason I say this is that sand is not the best surface for traction and too many variables are coming into play here. I suspect that tires will probably have the biggest impact on the outcome of any races in the sand.

With all of the tire and wheel comparisons we have done on hard pack and sand I don't think there was anything unfare about it other than the twin peaks was handycaped by about 15lbs of extra unsprung weght per tire over the weight of its stock tires and wheels. I think the proof is in the Dyno numbers From all the dyno work I have had done on my other quads I think vegasdudes numbers are dead on acurate. With the Polaris at a 160lb weigt disadvantage and less than 2 hp power advantage i would fully expect the twin Peaks/ prarie to give it a real run for its money on any surface.

 

yeah i ment 70MPH sorry for not making that more through... do you know how many horses your 800 is pushing at the crank

 

I've ridden both the Brute Force and 800 EFI and I own a 700 EFI. My friend had a BF and sold it and now has the 800 EFI....why, suspension. I just read in Dirtwheels that someone has shocks for the Brute Force, thats what it needed. But he like riding my 700 EFI, the storage compartments, etc. that he got rid of his BF.

When we rode, the BF didn't pound my 700 EFI bad and riding the trails I would smoke him due to the poor suspension on the BF.

Anyways, when I drove the 800 EFI, the acceleration is comparable to the BF. Considering the 800 weighs over 150 pounds more, thats pretty impressive. I could pull wheelies alittle easier on the BF than the 800.....

now here is the kicker....when I went down to the dealer this past Saturday, I was BSing with their sales guys....I was joking about trading my '05 700 EFI for a 800....we started talking about tires. The guy tells me that for the heck of it, they stuck 25" tires on the 800 and went out and rode it and raced the BF....no contest, it pulled the BF fairly easy. He said it was hard to keep the front end down and under control, that he was leaned over the handlebars on the start because when the clutch engaged it just wanted to come up....he made me laugh because he was joking around saying that he leaned so far forward that he just sat there and did a burnout....I laughed, not sure if he was $hitten me or not....but he said it was amazing with the 25" tires on there to make it the same as the BF....

Truly I like the looks and feel sitting on the BF...but the storage, ride, and EFI on the Polaris will keep me on the Polaris for now. I've always liked Kawasaki's....and also Yamaha's....my ole' Honda 300 Fourtrax was one of the toughest machines I've ever owned....

its a matter of what we ride, what is under our *** is the best thing there is...right now for me its a '05 700 EFI....but who knows next year......although I did keep my last machine for two years.....I think thats a record....

be safe guys and anyone that visits New Mexico, give me a shout and we'll do some serious riding....adios amigos....

Good point cc1999. But rear wheel HP numbers say nothing about gearing and clutching. Also a single number for rear wheel HP completely ignores the torque curve. I suspect the EFI will have a better torque curve over the carb. The weight may not be so much of an issue when you a add a 200 lb driver and 50 lbs of fluids. It sounds too close to call to me.

Interesting guys, keep it going, I too would like to see some more comparisons stock to stock as there's an infinite number of variables that can be added once changes are made from stock or are modified.
