Chrysler Crossfire + 55 Kompressor = Krosspressor

Illustration for article titled Chrysler Crossfire + 55 Kompressor = Krosspressor

The Chrysler Crossfire's 20% Chrysler and 80% Mercedes, but the best Mercedes engine given to us Americans was the SRT6 supercharged 330 hp V6. Someone's fixed this slight by dropping a very Bruce 55K V8 into a Crossfire. Krosspressor anyone?

If you've never heard of SPEEDRIVEN it's because, until recently, they haven't had much of a voice. Now that Jo Borras, formerly of Switzer and RENNtech's on board, expect to hear more of the loud, V12-powered screaming from the little shop in Palatine, Illinois.

Let's start with this Crossfire, which takes a 55K "Kompressor" mill and adds it into the engine bay of the underloved Chrysler-badged product. Note, the AMG 55K put out a maximum of 500 hp at 6100 RPM stock with a hair-rising 516 lb-ft of torque. Stock.


The physical swap was done by Rudy Coparty and all the work to make it work done by SPEEDRIVEN, including adding a rear differential from an E55K, programming the transmission, and giving it a custom manifold-back exhaust to give it the appropriate growl.

This car's a driving test bed for technology from the shop and, other than the PMY color, a good use of an extra engine. But why would you have an extra engine lying around? More on that later.

Duper, especially since Chrysler has been using older Benz parts for a while.

It makes so much sense, somehow...
