Is the top speed of stock viper slow?

Well to tell the truth I don't think the Viper will approach the mid-teens like the stock f7's can get (not all of them), I know that mine isn't anywhere close to that, I saw 115 on the speedo which is like 105 actual speed. Truthfully, the viper is heavy and slow compared to the F7, but look at the reliability and quality that you get with the yammie vs the cat. :yam:
 
I was hitting 119 on the speedo with the 1.25 track on a snow covered lake.I also was overreving to 8900 rpm.This year i plan on running a 1" track and adding 4.5 grams to my weights to get rpm down and hopefully pick up a couple mph.

You may be faster if you overev a bit.
 
Geeeez...The stocker we ride with ran 114. It's dead stock and overrevving like mad (which obviously isn't as critical as an srx).
 
my viper definatly had better top speed with an overrev. with 8 tooth drivers it tops out at about 95mph at 8,500 rpm. when it was revving 8,900 rpm it would pull 103-104mph with the same 8 tooth drivers.
 
in theory they will slow you down. i really dont know for sure though, i never corrected my gearing.
 
yes as n2o said in theory they should slow you down a little bit because you are bending the track on a tighter radius, which means more friction and a little less efficiency. However, you probably wouldn't notice much if any difference with equivalent gearing for the 8 tooth's.
 
what should a stock viper be revving at when the throttle is pinned? I have an 02 viper with a 136" M10 with the big wheels and a 1.25" ripsaw, last year i saw 121 on the speedo and the best ive got this year was 117. I wasnt really paying attention to the rpm's tho. I hit 109 with two people on it :P
 
you want to be revving around 8400 out of the hole, and between 8400 and 8600 rpms on top end.
 
My '02 completely stock including clutching and .92" track would see 128-130 on the speedo on very hard packed lakes, takes a mile or so to get there. That is 114-115 real MPH.

Also rode with triple piped Vipers and they were not any faster...they were quicker, just not faster on the top end.

now with clutching, different suspension, and 1.25" track I dont think i will see similar numbers again, but i will get to top speed a whole lot quicker.

I go on hcs a lot and the arctic boys over there seem to think a stock viper is heavy and slow and wont come near the top speed of an f7? What are you guys getting for top speed on your stock vipers? Below is the link to the discussion over at hcs.

That F7 is a fast sled. It will pretty much spank a stock Viper everytime. On my Vector, an F7 will take about a 1 sled-length jump on me and we'll hold even until about 80, then he'll walk away.

Now, a PIPED Viper, that's different. That will hold even or beat an F7 up to about 90-95, then the F7 will start to gain - it has longer legs than a Viper with stock gearing.
 
There use too be three f-7's in our group,and I would top end them with no problem,they are fast til 90 and thats it.
 
Had 123 mph when my Viper was piped. Guess that's going to be pretty hard to beat with the stock pipe.

when the viper came out in 02' a dealer had one out for a demo and they were running them wide open and getting 111mph stock, nothing else had that speed for that week. they are fast stock and my bet is it will beat a stock f7 on the top end. a stock viper not messed with will not touch a stock f7 on the bottom tho'.
 
My Stock Viper Mtn, was about half a ski lengh from beatin a f7 last year in the races... some dam close, killed it outa the hole, until about 60 ft at the end, it crawled up to me and took it, half a ski lengh or less for sure, it was neck and neck..

F7's come out of the hole hard! A stock viper with a stock track, even clutched with studs will most likely loose the hole shot. But F7's don't mph like a stock viper so the viper most likely will win the 1 mile race. A pipped viper will catch the f7 and go around at about 90-95. Now a pipped/clutched viper with a ripsaw or equiv. track will hang with it out of the hole and beat it in 600/800/1000 and top end by a lot.

I've beaten many modded F7's on the trail. So once you mod your yammi up you can hang with the modded F7's. But yes they are very impressive sleds!
