Wow bro that was a very optimistic dyno you saw there!!!!

reguardless of what you buddy tells you, most good running 416-440ex's are in the mid 30's when it comes to HP

I'M ON A MISSION TO RID THE ATV FORUMS OF LITTLE TRASH TALKING IDIOTS.......IT'S A LABOR OF LOVE!!!

Hell yea

[JDiablo]

what is a stock 400?like 24-27ish:ermm: so yea i would say about low to mid 30's seems right

[trick450r]

i would say maybe a fully worked one in optimum conditions might pull mid-high 30's...maybe

[Warnerade]

my 416ex hit 48.3

[Kilabanshee]

My 416ex with pipe,porting,valves,piston, and carb ran up around 40 hp. I've seen some of the 505ex stroker motors run around 50!:eek2: With the new turbo and nitrous kits available you could really be pumping some serious hp but your reliability is down the toilet.

[NikNacs67]

The one I was talkin about was a 505. It was in the 50's but I do not remember the exact number. And that seems pretty bad when a stock Cannondale Moto was pushin out 39hp and my Dale is pushin out 40 right now.

[FoxRacing81]

That kinda suprises me that there only in the mid 30s. I figured atleast low 40s.

Im not sure, I remember back when the 450r was coming out he had posted it for sale on the trx400ex group on yahoo.

I didn't catch it, but it must be a new hybrid. Kinda like a kfx426ex stroker big bore type thing. (I am really bored)

reguardless of what you buddy tells you, most good running 416-440ex's are in the mid 30's when it comes to HP

I think if you look through uncle Laz's old Dyno sheets you will see on with 51 or 52 HP.

[Rico]

my uncles friend's little cousins girlfriends sisters brother's buddy said a 400ex couldn't keep up with any of the new 450's and that the most HP you could get out of a 400ex was 18 so there's no way it was in the 50's.:rolleyes:

[wilkin250r]

That's just plain absurd. A 416 is a far cry from being fully worked. Call me silly, but it looked like the original question was "most hp".

You can't claim that a professionally-built, fully worked over, ported and pissed-off 500cc stroker is sitting in the mid 30's.

Dude thats weird...I was browsing in school today through a 2004 Fall/Winter Edition of RockyMountains catalog and I found a product (can't remember what it was for) And it said Yamaha and the first one was TRX450R...misprint but that was weird it happened in this thread.

My 416 is just a little upset, and I'd bet it's in the low-to-mid 30's.:D

Yes but that was a hand grenade...built by an engine builder i won't name.....it lasted just slightly longer than a 4th of july fireworks show, and exploded just as violently!!!

[02Yellow400]

east coast atv is building one for LuckyCharms right now and they are telling him 42 - 45 HP on thier dyno.. Granted it cost over 2000. But they can run in the 40's no problem

[86350x]

Lol, nvm:ermm: :confused:

[Juggalo]

my friends turbo 416ex is pushing an estimated 70 horsepower at 8 psi. we'll be officially dyno testing it later this year.

I noticed that too. I think all you people might be talking about different things. Are we talking about at the rw, or at the crank?
