On JKms rollers the K04 converted cars with REVo stage 3get neigh on the same figures as the OEM k04 cars with revo stage 2+.
So on JKms rollers your looking at 320-330hp, others 350-360hp. (390+ on AMDs
) Have you gone nuts on the chassis mods, Id get the full raft of them done,and you'll benfit from the money on a more regular basis, as let sbe fair a stage 2+ @ 280hp isnt a slow car by any means, and the mk5 chassis isnt the sharpest of the bunch when standard
