VIPER MPG

[tapex_07]

What are you seeing for MPG's?
Please list model of sled, turbo or n/a (and any pertinent info related), track size, driving style, air temps when checked, odometer, and type of trail you were on (hilly, slow twisties, long sweeping curves, lots of straight, or off trail only).

I know it seems a little ridiculous with all the details, but they all matter. And it'll help explain why we are seeing the numbers we are. Also, try to report full tank runs only.

Is this US mpg or IMP? 16us = 19.2 imp, so votes need to be in the same format.

My 14 XTX from new with stage 1 MPI would not brake 9 mpg even at 5#'s of boost. At 12 #'s it was a flat 8 on the button. I had to run 50/50 race gas and would be limited to 80 miles out and 80 back on that setup. I did have it switched to 9 on the low side and could run pump or at least less than 50/50. That sled is being re worked to be 350 hp + and should be done this week and we will see ho big of a pig it is now!!!!

My 15 has the old turbo, fuel pump and 4th injector from the 14 in it and is running stock motor no shim and is switched at 7 (pump gas) and 10.5#'s (race gas) and is soo much better I only have 390 miles on it so far but on a 90 mile ride last weekend it only took 1.4 gals more fuel than my buddy riding my 2013 Pro R 800 and he never goes over 60 and I never go under 100 ! I did not actually do the math but 90 miles / 8.4 gallons comes to just over 11 mpg.

Best ever was 17mpg on trail, just cruising. Average would be 15.5-16.0 the way my sled is setup. With all the playing I do, the MPI turbos this weekend were using about .5 gallon more than me and Shagman's turbo was getting the same as I was if not just a little bit better.

130 mi per tank easy. Anything over 100 don't care. 87 is cheaper than water!

15 RTX N/A Mbrp trail can 16.5 mpg mostly trail and a little aggressive riding.

15 ltx dx n/a, 2000 miles, ulmers intake, magnaflow can, 1.6 ice cobra track, 13 mpg average, I run mine hard on trail and try to mix in off trail whenever possible, should get better with the Evo flash.

XTX SE MPI 180 turbo

10 mpg ridden hard I have 1,100 miles on it

I am guessing gearing change would help mpg

15 LTX with Hurricane turbo. 16.2 mpg last weekend in wet heavy snow

Kind of odd that years ago Vectors were getting 16-17....

 

[cannondale27]

Heck the old carbed Nytro was 20mpg saw it bunch of times and not babied either. Suspension probably is reason for less MPG but easy trade off!

Vector has the detuned 120 hp triple, same motor as nytro and viper, just different computer tuning.

900 miles on my LTX LE with MPI trail turbo.
1st couple tanks were only 9-10 mpg, now running 13-14 mpg.

I can tell you my 14 with a stage 1 MPI would not break 9 with the stock 21/41 gears. My 15 is pushed even higher hp and has 26/44's in it and last weekend ran almost even mpg with my buddy on my pro R 800 riding like a girl and me blasting him all weekend and then waiting at the next stop sign. So it is closer to 12

Roughly 12 MPG, 2015 rtx le with 1.7 inch track and 21/49 gearing. (Hurricane turbo) In the boost lots but I can't complain. With the 21/41 gears combo I was around 15 mpg .
