On Friday I picked up my new Demon carburetor from FBO Systems in Beavertion. Josh and I pulled an all-nighter installing it in my Charger. We wanted to get it done in time for "Dodge Dyno Day" at Fast Specialties (and we did, barely). Things never go as smoothly as anticipated.

Turns out the old intake manifold (the 35lb orange thing in the second pic) has the wrong bolt and hole pattern, so it had to be replaced as well. The new one is an Edelbrock Performer. It weighs 14 lbs (big savings!) and is made of aluminum. In all, the car has a new gas pedal, driver's seat, throttle and kickdown cables, throttle bracket, K&N air filter, carb and intake.

With no sleep, we drove it up to Fast Specialties, in Vancouver, WA, yesterday afternoon, arriving just in time for the guys to tell us they were packing up to go home. After we told them what we went through getting all the parts on the car, Travis (the tuning genius) said, "well lets throw it on and see what it does!" I smiled and tossed him the keys.

The first run was a disappointing ~170 horsepower. Travis tweaked the carb to get the secondary butterfly to open and adjusted the
timing. The final run topped out at 210hp and 290 ft-lbs of torque. Its not as much as I had hoped, but its a start. Plus I got a 40hp gain just for driving up to Vancouver. Woohoo! The car definitely feels peppier than with the old carb, and it doesn't bog when I stomp the pedal anymore.

My distributor needs work next. It is supposed to vary the timing based on RPM, but its just keeping everything constant. I'll take it apart this week and see if I can fix it. That should improve things, and get back some of the low-end torque that's missing now with the the timing set for WOT.

I took my video camera, but due to lack of sleep I ended up with footage from only 1 dyno run and about 15 minutes of the inside of my pocket. Even through my coat the motor still sounds strong (<-- give it a listen). The last 3 pictures show the engine bay as it is now, how it was last year, and
how it was when I bought it several years ago. I like the progress.
