To put in one perspective if you are interested in 1000foot hard pack runs. My friend who just sold his viper had about 6 go's with me a month or so ago. This Viper had Slp triples on it with a 136 x1.75 on it. Again , it's not apples to apples since my Nytro at the time had the stock 1.25 x121. But in all races the nitro was ahead and even on a roll on had more mph. Even he was impressed with the Nytro after driving it...............not enough though since he went out and bought the apex..........LOL!
I'm sure this won't be every case but the Nytro does have great torque and power , not exactly the best topend. Mine has gps 'd consistant 97 mph and has gone 98. Now with a 144 x1.75 91 consistant with a 92mph. And it will rip your arms off ..................for a couple hundred feet anyways.
