Back in the muscle car era, there seemed to be only one way to make more power, and that was to make engines bigger and bigger. These days though, there are dozens of ways to add power without adding displacement.

Among the most popular modifications for muscle car guys these days are turbocharger systems, which are finding their way on to more and more classic cars.

User “Wilde Racing” on the DodgeCharger.com forums is fabricating up his own twin turbo kit for his ’69 Dodge Charger project. It’s a heavily involved project that requires a lot of custom work, and the build thread is a very interesting read.

Now the Dodge Charger certainly has a huge engine bay, but that’s because it came with some huge engines. This particular Charger isn’t anything special, having been optioned with air conditioning and a 383 “B-Block” engine.

Previous owners of the Charger had done some questionable modifications, like cutting the floor and torsion bar cross-member in order to put in a floor shifter (this car had a three-on-the-tree manual transmission from the factory). Another issue is that the rear shocks came up through the floor due to some Dukes of Hazzard-style jumping.

However, the biggest challenge will be getting the twin turbo system to fit.

Wilde Racing is no stranger to custom fabricating turbo systems, having done a custom system for his 11-second truck. But the Dodge Charger presents its own set of challenges, and the turbo piping system requires the headers to be installed piece-by-piece.

The engine in question is not the worn out 383 but a beastly 440 capped with a slick Edelbrock intake manifold, and working around this portly powerplant isn’t easy. The project is still in its early stages, but if you want to see devotion and hard custom work, make sure you check out this thread.
