where's all the high hp vipers at?

[jpnytro240]

Haven't seen any reviews or any results from any high hp vipers I'm talking 270hp+...I'm coming back to yamaha after a year on a pos turbo cat! Just wondering if there have been problems at these power levels as far as drive line and such..my nytro was flawless at 330hp and trailing at 270hp just wondering if the viper can take it like the nytro cuz believe me I don't want another headache like I just got ride of any insight would be helpful.

I take it no one is running a big boy kit yet?

Any drive line problem at 270+?

 

[CustomApexMan]

Honestly I would not even think about buying a kit with less. mcx 270 runs awesome don't even try it with out the intake through the hood

 

[CustomApexMan]

No but not alot of miles yet

 

[jpnytro240]

What kind of speeds you seeing?

 

[CustomApexMan]

110mph gust hanging the throttle for a few seconds

 

[jpnytro240]

So you should be able to gear it out in 600-700ft or so?

 

[CustomApexMan]

Well the field I was in is 900 ft I was hitting that just past half so around 500-600ft roughly have not done any long runs that's with a 8dn with ulmer secondary mod

Mine at just 6 pounds will shift out stock clutches and gearing in 900-1000' marked off, 109 mph bouncing off rev limiter. More than likely gonna jump up to 10-12 pounds over the summer.

 

[jpnytro240]

You both just have head shims or built engine?

 

[CustomApexMan]

.080 shim plus a split gasket so around .100 total. throttle response is great about no lag

 

[jpnytro240]

So yeah about the same as the nytro...what kit are you running?
