Has anyone ever ran their 400 or 450 in the 1/4 or 1/8?

[idro]

If so, what did you run? Trap/time?

[troyleepred719]

predator 500, with airbox, jet and pipe, 13,43 in the 1/4 @ 89 mph

[WhiteZrider]

Hmm i went to this grass drag place, it wasnt that far off from a quater mile i think just like 100-150 feet less and i think my time was 9.17 at like 59 mph(slow) :ermm:

I'll believe it when i see the time slip

[Scro]

8.95 at 72 mph on asphalt. That was with a 450r with HMF exhaust.

02' 440ex on asphalt in the 1/8th...8.97 at 71mph...

why is a sub 14 second quarter not believable with a quad? with taller gearing on a preddy its definately possible. i found a 250R on ebay once that only had minor changes on it and it ran the quarter at 92 MPH and he had the time slip (dont remember the time but thats the right MPH)

if you think about it Scro got 72 with his 450R in the 1/8 with just exhaust. troyleepred719 had exhaust plus a different intake (if you've ever seen a preddy intake and the difference an aftermarket one makes you'll know where i'm coming from) jetted for those mods and geared different its definately possible to run that.

not to mention say Scro's 450R hit 72mph in the 1/8 lets just assume thats the top speed of his 450R, so if thats right then 72mph/60minutes=1.2 miles per minute/60 seconds=0.02 miles per second so if he's traveling .02 miles per second(105.6 feet per second) then the second half of the quarter (660 feet) will take about 6.25 seconds putting him at a 1/4 mile time of 15.20@72mph, 1.77 seconds off of troyleepred719's time of 13.43 and 17mph slower, and he could easily pull a few more MPH than that i'm sure especially with some gearing. so its definately possible.


oh yeah and a stock LTR with a CRBM will pull 96mph just by putting 20's on it and about 88 or so with the 18's and i'm pretty sure that it tops out well before a quarter mile.

oh yeah and a stock LTR with a CRBM will pull 96mph just by putting 20's on it [/B] Is CRBM a 'CherryBomb', and if so, I'm pretty sure thats impossible to hit 96 with just a cherrybomb...sorry.

[250ex13]

250ex, jet and pipe, 0,0 in the 1/4, 2 minutes at 17 mph on asphalt.


Yeah, it's fast.

yes CRBM is cherrybomb... but you missed the last part of that... "if you put 20's on it" i mean 20 inch tires in the rear if your wondering. that was by the speedo in my 2001 taurus which i know is very accurate because i've ran it at 100 with my GPS to check it before. with the 18's on the back they pull around the 86-88mph range... they are very tall geared for what they are from the factory esspecially for the fact that they have 18's on them and pull into the high 80's, my preddy with stock gearing can only pull into the mid 80's with 20 inch tires and its in the high 70's with 18's.... but now my jetting is so far off with the cold weather i'm down probably 4-5 mph at least on the top end...

and the other thing is... have you ever ridden one of them? and if so have you ener clocked one of them with a car? its surprising what an LTR can do and what the difference a CRBM actually makes in them, they go from just a length or 2 win in a drag with a stock 450R to about 6 lengths and thats in about a 500 foot or less stretch that they can do that.

this is all from my own personal experiences that i've had with the 3 machines and even with me and my buddies rotating drivers on the machines for that matter... but i guess this is the internet and you have to be skeptical of what other people say on the web so i dont blame you for questioning

you must have had a FAST 60ft time.......my 426 ran 74mph but just at 9.24 . But after being around all those drag racers for a little while they explained your launch and 1st 60ft is usually where you make your time. Because there was constantly people running faster mph but slower times and it was very confusing before they explained it :confused: There was a guy there that had one of Jeramiah Jones old YFZ TT quads and it was running 7.80's :eek:

[gitrdone]

I drag race my 426ex all the time on a 300ft. track I usually run 6.2 sec. at 49mph. All I have on my bike is the 426 kit k&n air filter white bros pipe and use vp-110.

[honda250xrider]

ltr's will not do 96 with a cherry bomb and 20 in tires, and will not do 88 mph with a cherry bomb and 18" tires, i wanna know where you got that at lol, stock they do around 73-74 mph. The cherry bomb does not do anything but up the performance, only way to gain speed is to change the gearing or change the rev limiter/tires. So 96 with just 20in tires i call BS

[PolarisRider06]

CRBM's up the rev limiter and change the fuel map....

we got the info with my car's speedo, may have been a little bit off of what he was actually doing because its harder than **** to exactly match the speed of someone driving along side you down the highway so i may have been going 1-2 mph faster or slower but still LTR's are faster than **** and once he takes it out again we'll re run it with a GPS on the bars to check again.... also i'll have to call him and ask what the speed was that it ran next to my car, myabe it wa 90 with 20's on it and something else that we ran along side my car was 96 but still 90 is fast

and like you said the only way to gain top end is gearing and rev limiter. i know that, i always have known that, the CRBM ups the rev limiter and 20" tires ups the gearing, there you go you got both of them. we never checked the speed of it without the CRBM because he had it almost right after he got the quad, and the 20's were WAY over inflated so they may have been 21's or 22's actually i dont know so that also effects the outcome


honestly i dont care what you think, this is the internet, its not worth arguing about anything on the internet its just retarded.... i'm just trying to state my experiences that pertain to the questions at hand and be done with it. i come back and read what other people say and see if there is anything else i can do to help or info that they might like to know and i'm not gonna argue about all this crap on the internet. i'm not here to argue, thats what drove me away from this site for a long time i'm just here to trade information with people and learn new things about quads from other people and help people out whenever possible.

if you dont believe me just say it, which you've already done, dont try and argue about it anymore you've stated your points, i've stated mine, obviously we have different ideas on it and maybe someone will come on here with some other information to straighten things out, who cares if i'm right or your right its the internet we've never met, probably never will and its not like its some life changing thing we're talking about.

like i said before thats just my experience with the machines yours may be different... to each his own
