Yeah, I imagine 450 hp will do the trick at any speed too, but can't vouch for it since I have never had that kind of power under a 190E 2.3-16 hood. When you start working the chassis keep us informed. All our 16 vavles are stock, including the self leveling rear suspension. Works pretty good if you keep after the spheres. Once they go solid the struts get beat to death and the connection to the bottom of the strut, an aluminum part with a female thread with a steel stud screwed into it to hold it to the hydraulic cylinder to the mounting block, gives up the ghost resulting in banging and a rock hard, non-functional rear end. And those rear struts are not cheap.
