I heard that one respected member on this forum made 250hp with k1 turbo...so I guess k24, wich is bigger, would make 250+ hp with correct supporting mods and good mapping... I am talking about flywheel figures... either way k24 was made for great middle power and good response, so its nowere near laggy k26 which is ofcourse capable of 300hp..., but it all depends on where u'll need this power: street, drag, track...
