Does anyone know what the hp rateings are(at the wheels) for the; EX,R,and Z.

I thought the EX was 24ish(400)
-----------Raptor was 38ish
----------------Z was 34ish

Does anyone know???

Some are saying the Z only has a few hp over the EX. I wouldn't think that this is true because too many people are (in theory) beating the EX(straight line runs). Only a few hp isn't goeing to make enough differance to cause that many decisive wins(again, only straight line drags).

I have seen the #'s in several differant posts but I never know when it is at ther rear wheels or crank.

Just wanted to know what the "true" numbers were.

I saw somewhere the other day that the 300EX has 17 hp. If this is true and the 400EX has 24 hp, that is 7 hp differance. This should give us all an idea how much 7 hp makes!

Later...

 

Go here Dyno Report They have Dyno runs on a stock Raptor, EX400 & Z400

That should answer that question once & for all.

 

Let me set the story straight.

Click here for dyno numbers


OK, www.sportquad.com did the dyno's on the same day, the elevation was the same, you can be sure the bikes were all tuned in properly. By the sounds of it they love the Z400, so they wouldn't go and give it a bad dyno run. You maybe saying that these numbers are lower than other dyno numbers you have seen and that these dyno numbers can't be true. Well dyno's are not consistent from day to day because the atmosphere changes. You need to do the dyno's on the same day on the same dyno or else you can NOT compare dyno numbers.

This is what they had to say just in case you can't get to this website.



<< The new 2003 Suzuki Z400 made 29.34 HP on the Dynojet Dyno. A stock 400EX recorded 25.98 HP and a stock Yamaha Raptor showed 36.04 HP. While the Z400 may not be up to par with the Yamaha Raptor you need to remember that is also 260cc smaller displacement engine. >>



This is what happened when they added a dynojet kit on it.



<< While at the Dynojet Research and Development facility we also wanted to see what a DynoJet kit could do for the Z400. With a Dynojet kit installed and airbox lid removed the Z400 produced 31.29 HP. Nearly 2 HP improvement over the stock Z400. Not Bad! >>



So the Z400 is 3.36 hp more than the 400ex and the Raptor has 6.7 hp more than Z400. You need to look at the dyno graph and you will see why the Z400 is faster than the 400ex with only 3.36 hp. Its all where the power is, not just how much you can make. Peak horse power means nothing, dyno graphs mean everything. I just wish the graph had torque numbers too.

This is the truth. These are the facts. Plain and simple.

 

That's just one test. Every other one I've heard over the part few months has been EX 25.5 HP, Z 33 HP, Raptor, 34 HP.

 

Thanks guyes, a pic is worth a K words!!

Thanks!!!

 

You can't compare past dyno's to current dyno's on low horsepower machines. On trucks and cars thats different because a 5% error on the dyno for quads means way more than 5% on a 500 hp corvette. That 5% error is contributed to the atmosphere changes and the dyno operator.

If the hp figures you just gave were run on the same dyno and on the same day then your numbers are correct too but only for that day, on that particular dyno and at that elevation. If the hp numbers you gave were from various sources and every other dyno from this day to that day then they mean jack _____.

Dynoing is not an exact science and you can not reproduce the same hp numbers from day to day even on the same dyno.

 

Z400 owner's please don't get upset and raptor owners please don't go all bragging. The Z400 should have less horsepower, its way smaller in the engine department. I for one fully expect my Z to be slower and less powerfull than a raptor and the raptor guys should fully expect the very opposite. This is all true if the machines are both tuned properly but this is not always the case and the Z400 may spank a raptor sometimes because of this or rider ability and vice versa. Its a fact of life. I wish we could all accept this. I hate seeing all these flame threads about I beat this and I beat that and it gets flamed to death. Its still going to happen but you can't make everyone happy. I know by tomorrow this thread will have a few flames in it. Another fact of life, on the internet.

 

who cares about the numbers. The Z400 is the quad to dethrone the 250R. plain and simple.

 

Break the Z in before dynoing it at 29 them.
