18 after pipes and jetted around 22

do a search for warrior hp and there are a few posts about it

thats where i found it about 30 seconds ago

 

Sounds about right... I've heard 16-20.

 

i've always heard 18-20

 

Agreed!!

Unless they've changed their dyno for the Warrior it's just plain wrong. The Warrior is not making anywhere near 30hp. It makes about 24 at the crank and around 18 at the rear wheels, stock.

 

FMFs numbers do seem a bit inflated, but they could be measuring another way.

I've heard on the DYNO machine that the Warrior will make about 18-20HP at the rear wheels.

However I'm sure the BRAKE HP measurement would read a lot higher. There are a couple other ways to get HP readings besides at the rear wheels.

 

When Yamaha was posting performance data, the Warrior was making 20.3lbs-ft torque @ 6000RPM. That's measured at the crank I would presume, though it's not stated. Using the dyno formula of torq x rpm / 5252, that gives you a shade over 23HP at the crank. Not sure if there's any difference in crank horsepower and brake horsepower, but the only legit number or important number in any event is the wheel horsepower because that's what you're putting to your contact patch to make you move.

You could have 80HP on the crank and a horribly innefficient drive line where you loose 62HP, thus leaving you with 18HP at the wheels and you'd be no better off. You'd probably actually be worse off since the 80HP motor most likely weights a heap more than the 23HP warrior motor ..

Anyhoo .. nuff of my rambling ... sure would be nice if the Warrior was makign 30HP with a simple slip-on .. that would be sweet ..


Also, I just took another look at the FMF dyno chart ... they quote those numbers as being at the rear wheels at sea-level using the stock air filter and airbox. Peak horse looks to be around 33HP SAE measured. According to the Raptor Dyno .. the stock one puts out about 38HP, which is in the ball park for a stock raptor. So that's a big clue about the validy of the numbers on the warrior .. air cooled 350cc 2-valve 4-stroke putting out nearly as much power as a 660cc liq. cooled 5-valve stock-for-stock?? Nuh-uh.

 

20 RWHP stock -> mine currently makes high 30s
