any one got a dyno sheet for the ds450?

[driver311]

LOL my name is anthony and I live in boise idaho. My dyno is a dynojet chassis dyno. Ive never said anything about your first statement. Ive always said that no box intake systems make the most power. WhY? becuase they do. Go to ltr450hq and look at the dyno section. Ive posted at least 100 dyno graphs of everything ranging from, yami450, honda450, kawi450, ds450, ktm525, pred500, raptor700, and the list goes on and on.
Ive done pipe, intake, and cam shootouts on 4 different machines. There is one thing in common with each test. Dasa is on top. Big time. I have never gotten one cent or any kind of discount from dasa for any of my work. Ive sold hundreds of dasa pipes for them and they dont give me even 10% off. So the only reason I preace dasa is because it works so good. Thats the plain and simple truth. Believe me or not. im only trying to help. Sorry if you dont like the facts I post. But they are facts based off many many many hours of dyno time and research. I havent gained shit over the years except for guys like you calling my bluff. LOL

maybe Ill learn my lesson and stop trying to help peeps. Dont get me anywhere. If you guys like Ill stop posting graphs and info that Ive learned over the years. Shit I dont even have a ds I dont know why I waste my breath. Have a good day guys. Late

Driver311 don't listen to those guys, there're upset that they wasted all their money on motoworks and fmf pipes. Just keep on given us all the info you got cuz the dyno don't lie.

Don’t tear drip now Driver you’re making me ball too….lol! You’re little Shenanigans
may work with your girlfriend but not out here among technical fellows . Look here is the way I see it and you know dyno runs can vary dramatically….I talked to my car buddy, has a 500 hp camereo show car about this morning and we both agree……Here is what I posted on ATVRIDERS about boxes below and intakes …the whole idea is to DECREASE velocity and INCREASE pressure…..I work around some of the best aerodynamicist in the world, been in some very sophisticated wind tunnels….Forget your dyno and THINK about the aerodynamic flow here for a sec.....

You can guess or speculate but without using a pressure gage and some flow checks you don't know what air box mod's will work. Drilling holes in your box or removing it can cause a lack of pressure due to turbulence. The intake is a divergent duct that is designed to decrease velocity and increase pressure before it enters the throttle body, only so much pressure can fit in the chamber and the box has been carefully designed to do just that. These big factories use CFD(Computation fluid dynamics) to design not guessing.....If you have a stock motor leave it alone. If you have a modded motor the mechanic that did the flow check should know what works and that will be very specific to the engine build and design

Stick around Driver and put your dyno aside, you might learn something. Many of the best Engine designers in the world did it without a dyno.

PS: Only purchase I have made so far is a 09 stock DS, thats it! :P

driver, please don't quit doing what you're doing for us. you're the only person who has given me useful information on my new quad. there isn't much help out there for the ds450. you're nice enough to waste you're time on a four wheeler you don't even own. i don't know why people are trying to run off great information just because they think you're wrong. please keep doing what you're doing.

Don't worry our friend Driver ain't going anywhere he'll be dyKNOWing all night seeing if I am wrong....lmao. K, Happy New Years I am off to Oklahoma City to bring in the New Year.... :P

Driver I’m not saying your wrong so don’t misunderstand me…..I’m just saying guy’s look at the air flow through a quad as a system and have a better understanding of that system. It’s based on Bernoulli’s principles and venturi’s, we decrease velocity and increase pressure at the intake then decrease pressure increase velocity at the exhaust. From the intake to the exhaust there are a lot of variables such as the size of the filter, intake duct, TB port, volume of chamber, stroke of the crank, head port, pipe, so if a dyno shows that system good on one quad we can’t assume it good on another. If we change the intake and the exhaust on a Honda it does not mean we get the same results on a DS unless we verify it. Chances are we won’t since the engines air flow are designed differently….also when it comes to air we have to dyno under the same density, barometric pressure, and humidity to accurately compare.

The DS has no room in the box for a bigger filter for modded motors so I can see due to geometry the need to remove it. I'm also leaning toward DASA doing my motor.....they ARE reputable company.

My son rode the pink wire cut for the first time yesterday and said he noticed a sizable gain in torque and power. We can't wait to get our motor done we think this quad is going to RIP!! Anthony you need to get one.

I guess the fact that I have been building and racing quads for the past 10 yrs dont really have much to do with it either?? The dyno is just a tool to prove what already know and learn a few things along the way. The only benefit I get from it is helping others not purchase most of the junk out there. Its crazy at some of the stuff Ive tested that just doesnt work. Yet these companies sell the crap outa it. LOL Its a joke.

I know it's crazy what people will believe and buy into.....Hey don't get me wrong I respect your experience and knowledge. Next time you have a DS box look at the taper from rear(wider) to front, it's the divergent duck I am talking about.....Our YAM box on the other hand has no taper has a bigger box and vertical plastic blades on the inside side walls of the box to allow a bigger filter and more air in the box surrounding the filter. These blades are vortex generators that reduce turbulence.

anyway keep letting us know what you discover and I work around some of the best engineers in the world I can get answers and explanations too....I'm a structures engineer that is my forte'. Together we can conquer the world.....lol!

Driver you are the man. I belong to most of the HQ forums and have listened to every word that you have said. I race pro MX on an LTR but am deciding on contract with KTM, Can AM or Suk. Keep up all the great work and any lowdown on what you think would be a good signing move for me would be greatly appreciated. Also, I have access to some equipment for you if interested in testing.

i talked to ron woods today and he told me the ds was 43hp stock and they got 47 w/ the pipe. he said they didn't change the fuel map because they didn't have a power commander yet. he said their pipe & intake w/ a pc3 on an ltr makes 47. he said the stock number on the ltr was 34. the stock number he gave me doesn't sound right. what fuel management did they have when you dynoed the ds450 w/ the ron woods, driver?
