What is the top speed of a stock scrambler 5002wd?2nd what mods will i have to get to beat my friends scrambler on my trailblazer?

 

Hope your pockets are deep. To beat a stock Scrammy, your going to need the full reed conversion kit from HPD (including all the options). And even then it will be a close race.
The Blazer is nice, but it was never meant to compete with the scramblers

 

at least he doesnt have a scrambler 400,
or youd be without all but the faintest of hope,
you should visit HPD's website or hot seats,
the money youll spend just to beat your freinds,
you can pick up a used scrambler 400, 2x4 or 4x4 for a little more, and that will beat a 500
oh yeah, top speed on a sc500 is 65 mph, sc 400 67 mph
