Have been intreagued by the Zilla for years now and am considering trying to find a good clean one. Anyone know the stock horsepower of the lt500 at the rear wheels? how about after adding a pipe and jet kit with a K&N? Thanks!!

 

A good healthy stock zilla with good compression will push 45-50 RWHP stock.
What makes a zilla so much fun though (IMO) is the massive torque on tap at low RPM.

pipe ect im not sure, though as with any other 2 stroker, im sure it wakes it up.
(mine had that when I bought it..)

 

when they are measureing power to the rear wheels what gear do they do it in 5th or 4th i am only asking cause i beleive 4th is 1to 1 and 5th is od and mine made 40 to 45 in 5th but it isnt stock

 

I believe they use third most of the time.

 

so if they do use 3rd mine is makeing great power then
