Un­leash Hell­cat

Wheels (Australia) - - Firstdrives -

Trackhawk’s en­gine is lifted from the Dodge Chal­lenger Hell­cat, so it drips with mo­tor sport­derived tough­ness. It runs a forged-steel crank­shaft, forged-al­loy pis­tons, pow­der-forged con­rods, and al­loy heads fit­ted with hol­low-stem, sodium-cooled ex­haust valves. The su­per­charger runs at a max speed of 14,600rpm to de­liver full boost of 11.6psi. Its twin­screw ro­tors are coated with a mix of polyamide and other nano resins to en­able tighter clear­ance be­tween the ro­tors. It’s a beast of a donk; its out­put com­fort­ably eclips­ing the 474kw/815nm made by the same-size (and also su­per­charged) Gm-sourced LS9 fit­ted to the GTS-R W1.
