how much horsepower does an 03 MTN Viper have?

[catmechanic]

just wondering what this thing has. its all stock. i was thinking 135 but im not sure. any help???

 

[valin]

I believe the Vipers were around 115.

 

[catmechanic]

really? i would have guessed more than that since they have power valves. it is the same as an srx only with a single pipe. what did the srx have for HP?

 

[valin]

140 ish, depending on year.

 

[Thumper1]

i thought the vipers were around 118-122 HP?

 

[catmechanic]

i think that 125 is right. thats what i found through a google search.

 

[valin]

Could be 120-125. I always thought they were about the same hp as the red heads, but maybe they're more. I dunno. All I can tell you is that it's not enough

x2 on 118. Remember that is sea level, you will loss some with elevation.

I would guess 120 to 125 cuz I remember them being about 15hp less than the Firecat when they came about.

Nothing some tripple pipes wont fix.

Seen them dyno as high as 127 and as low as 119. 122 -124 is average. Can hit 150 with pipes.

On the dyno:
Stock Viper (single pipe) is around 115-117.
Triple piped is around 144-146

The DYNO sheet I have seen shows them peaking at 115.4 @ 8400 with a nice flat forgiving power curve...above 110hp from 8200 - 8800
