Street Car Takeover – 660HP TT Rail Job

January 29th, 2018

What could be more entertaining than a little Willis Jeep with a big old (twin) turbocharged V8 engine? With most of the cumbersome body eliminated, the vehicle is not only lighter but also much easier to work on. Although not the prettiest car in the lot, it does have a certain Mad Max meets Speed Racer quality that is very interesting. Let’s take a closer look.

At the heart of this creation (that has been named Deathtrap) is a salvage engine that drives some other rudimentary but key components. The driving force is a 5.3-liter LM7 (GM) engine with steel cylinder head gaskets and aftermarket high performance cylinder head retaining studs/nuts. The bottom end was left intact but up top a set of LS6 valve springs were added. Forced air induction duties are handled using a pair of Borg Warner S366 turbochargers. A Turbo 400 automatic transmission with a RoadRunner torque converter transfers power to a junkyard Ford 9-inch rear differential. A cobbled Ford Crown Victoria front suspension keeps things going straight down the track. The Deathtrap makes 661hp  and 805 lb.-ft. of torque. It is hooking on Mickey Thompson rubber and has posted a best (quarter-mile) elapsed time of 9.95-seconds @ 135 mph.

This critter comes out of the hole hard, sticks to the track like glue, and consistently blasts from A to B without incident. I love it!
