70mph IN 4th GEAR!!! 1/8th mile time...

[JOHNDOE83]

That's right, I said it!!! 70mph in 4th!!! with PLENTY of hp in 5th still to go....only 1 issue?

I went to countyline dragway last night and draged my ex, and discovered good's and bad's...

The good's: 400ex will go over 75mph, possibly 80mph or more? "soon to find out"

The bad's: 80mph in the 1/8th, I doubt it, here's why...

In the 1/8th I never got to fifth gear, my best time was 9.097 sec. at 70.7mph...it "WILL" deffenitly go past 70mph in the 1/8th with some gearing changes, Im guessing I can 'maybe' get 75 out of it who knows maybe more?...I dont think you could get 80 or 85 in the 1/8th with a 400ex, unless you had turbo or nitrous, WE WILL find out tho...lol... The record ATV time there is 5.85 sec. at 128.2mph...I do not know what type of ATV, or even if it had a ATV motor?

I needed to change my sproket's again, but in my rush to leave that was the only thing I forgot to pack, I only had a 36t rear and 18in tires for gear changing, but I did find out that 80mph is possible on a 400ex...and 70mph in 9sec on the 1/8th isnt a "Bad" time, a gxsr that was trailer'd there and "severly" fast ran high 6s at 109mph, I didnt ask or notice if it was a 600 750 0r 1100...sport bike's easily do 70mph in first gear anyway...

I was running 22in tires 16/39 gearing and my mod's, with 16/36 gearing and 18in tires, in fifth gear, almost toped out, runs the same time and speed, I didnt bring all my extra stuff for tuning, but will in the very near future get better 1/8th mile time slip's.

What do you guy's think about that?

I think you're full of crap...

[Thumpin440ex]

In ref to the top speed of the 400ex, my 2000 400 would run 71 mph on gps, stone stock..

Same here. With the trailtech vapor it topped out at 71.2.. but took FOREVER to get there.

Well I guess it could be possible.. if you don't mind me asking how much do you weigh?

[Thumpin440ex]

220lbs

:rolleyes:

[JOHNDOE83]

Well im not full of crap...its true...4th gear 70mph...in the 1/8th

I weigh 155lbs.

Anyone wanna findout for yourself go to countyline dragway here in south florida and watch me do it for yourself....

Bring cash....

[odog]

yes its possible it was a few guys on here that use to drag race there ex alot of them ran similar setups as mines just different carbs one had a 450r carb and the other had a elderbrock. but we had the same 460kits and if im not mistaken one guy said his ran 76 or 77 in the 1/8 and in quarter it ran 84-85mph. ive even ran over 80 on my trail tech vapor im thinking about buying a rader gun so i can see how accurate it is i now that its dead on up to 55mph but never tested it beside a car running over 55mph.oh yea before everyone say that it isnt possible the guy had the time sheet. to prove it

[JOHNDOE83]

whats so hard to believe, I to will post my time slip if anyone thinks im B.S.ing...

do you ever shut up?

better yet just go away.

[krazyrider]

i was on a straight, flat road using my garmin gps i hit 73mph on my 07 400ex with stock gearing & tires. k & n air filter (lid on). jetkit. & a full HMF bill ballance exhaust.

afterwards...

i strapped my gps on my buddies raptor 700 with a hmf slip on, no other mods. on the same road my best run was 78mph.

im guessing the numbers were decent considering i weigh only 135lb.

ya know, instead of being jealous or upset that yours isnt as fast as mine. you could ask me for help to tune your quad to run better.

lol jealous and upset? The 400ex isn't a race quad. I loved mine for what it was, a trail/woods quad. That's also why I sold it.. 1 I needed a car, and 2 because I wasn't about to dump that much money into the motor to keep up with a piped banshee.

I'm not the one being an jackass right now, I did a little research and learned that number isn't that far out of reach. I think you're the one trying to start a fight right now. But I'm not going to.

And ask you to help tune a quad? I'm plenty capable of building motors and tuning them. Riding a quad with two carbs, I learned a little something about tuning in the past year or two.

By the way, the average 1/8 mile time for a piped/filtered banshee is right around 8.6-8.8
;)

[davidhoe]

For a 400ex that isn't a bad time. I don't think you are going to do 80 in the 1/8, It would take probably another 15-20hp to pick up 10mph. Turbo530r had the fastest 400 that I know of and I believe was running low 8.0's to hight 7's. If you are wanting to go fast than a 7.80 just brake down a buy a banshee for around 4-5k you can run 6.40-6.80's. To run 5.80's or quicker it is going to cost big $$. I have a 4mm cub motor (banshee) and was the funnest set-up I have 6.7's all day on gas with over 150 passes on it and the pistons still looked great. I also have a 610 cheetah that sould run 5.80's just have to get it right. Another thing you have to think of is time to shift. On my gsxr1000 1 shift added .15 and that is with a airshifter and kill time set to 50ms. I would have fun with what you have change little things to get as much out of your setup and maybe put a 15hp nitrous hit. Also what are your 60ft times and your chassis set-up. Just trying to help.

[John Noftsinger]

My ex stock did 65 tops with 22in rears and 14 /38 gearing so if i went to 16 in front i could have went 73mph thats 8 mph increase seems too high for fouth gear,what other changes did you do besides a 440 kit/16 tooth front to get that speed I now have z and it does 73 with 22 rears 14/38 gearing both quads I ran there speed with car beside me.

[JOHNDOE83]

There is alot of factors that go in to getting that fast....

one is rolling resistance the tires I have are very very low rolling resistance, putt a 20in regular nobby atv tire on your ex and push it, then put on slicks and push it, it will be much easier to roll...

Then you need gearing, look up 400ex gearing calculator in a search engine like yahoo or google...get a mph reading on your atv then go to the calculator and type in your info and adjust the rpms till the speed matches yours and youll know what rpms your puttin out....

Also you need power to push them gears and tires, thats why I have the 440, cam, carb, cdi box, no filter, custom intake tube, tunning, no exhaust tip, BIG jets, I adjusted my valves to compensate "not the way described in the install instructions"....etc.

Weight has alot to do with it, my times would have been better with my DRAG shocks they are less then half the weight of my 450r shocks and the rear, I only weigh 155, my axel is lighter then a stock axel, those rims are thin .125 blue labels, Many many things go into it.

Other then getting actual video, any suggestions on how I can prove it?

my 60ft time was 2.032 and my chassis was basically stock other then 450r shocks, I still have drag shocks and rigid alumminum drag bars im trying this weekend. Any help is appreciated.

[davidhoe]

I run struts at a ride height of 2-3", set the toe to 1/8-1/16 toe in. Get as much weight off of it as possible. You need to work on your 60's. I run 1.38-1.39 with my small motor. If you can get down to 1.70-1.80 that would help alot. Is this going to be a drag only bike? Also get a +6-+8 arm that is lite. There are alot that are 7-8lbs if it is just a drag set-up.

[davidhoe]

Post a pic of it. That willl help out.

[JOHNDOE83]

Im putting my money on the gearing, if I go 15t 0r 14t I think Ill hit a good area...

Ya im deffinetly doin struts, I didnt know some swingers were only 7-8lbs thats a big difference. Im thinking +2 will be best.

The way Im set up know I can go from street drag to dirt drag to trails any one, within 45mins of wrenching... I figured +2 wont hurt trail riding ability.

With my struts I replace the weight of all three shocks with 3lbs of aluminum.

Get an exhaust for it you could pick up some power with the whole pipe. When those tire stop hooking get some american racer 20x8x10 in a sd23 compond. The 7lb arm I would not ride in the woods as it isn't made to be beat to death. get it low and the toe right that will help get those 60's right. Just see how quick you get the bug to go fast and than go from there. When that time comes ditch all the bs thing you don't need and stretch it. A set of adjustible arm would be good to get as much caster as you can so it will not be so twitchy. Cut the front and rear plastic. Get on planetsand.com and check the 4stroke section out

[davidhoe]

When you setup the chassis try to get the swingarm parallel to the ground.

[JOHNDOE83]

ya im on there now...lol.

Im also on my way to doing all the trimming, already got rid of 4lbs of un needed nuts and bolts. I also have 18in slicks that wont even let me do a donut on pavement but I need 20s I agree.

my struts are way lower then the way it looks in the pic with the shocks. paralel like you said.

[davidhoe]

get that stuff done and try it out, you will get out the hole lot faster

[Thumpin440ex]

Hell, I though you were doing this on stock cubes.. I will more then agree with you now, that it is doing that in the 1/8. Def need to get a full pipe kit on there.. While it will get you only a few hp in something like this every bit helps

John

[JOHNDOE83]

I tested it that same night and without the pipe I actually gained 1mph. IDK?

And most drag bikes run only headers for a reason, more air, more fuel = more hp...

[dgerstung82]

You must have a lot of more mods than just sprockets on that thing to be running that fast in the 1/4 mile. I would have to see it to belive it.

[400ex=awesome]

mine goes 73-74 but i have a k&n air filter and a bills exhaust and im putting in a stage 2 hotcam and a rev box and heavier springs so its gona go 75-80

Who cares about top speed.. lol. Riding is mainly offroad, where you will almost NEVER use the quad's top speed. Every quad I own I usually end up gearing LOWER or leaving it stock. It's not about top speed it's about how fast you get there.

Acceleration is where its at.

[400ex=awesome]

yeah but its always cool to know that your quad is fast but the place you need tops speed is racing and stuff like that
