Project Blackbird Firebird on the Dyno

Firebird owner showcases his turbo drag car, in this short, sweet and simple build thread.

Some build threads here on LS1Tech walk us through each step of the process with a detailed explanation of what was going on and why the owner went that route. Other build threads are short, sweet and to the point, including a mod list and a whole lot of pictures. The story of Project Blackbird fits into the second category, as forum member “ws602” laid out his entire build in pictures while keeping the text to a list of features. In doing so, he has shown how his 2002 Firebird was built up to send more than 1,000 horsepower to the rear wheels.

The Introduction

When the OP first introduced the forum to Project Blackbird, he did so by sharing a full list of modifications included in the build. He would share that same list every couple of replies, mixing it in with the many pictures that are included in the thread.

Lots of Images

While the OP would copy and share his mod list over and over again throughout the build thread, he did so while sharing a ton of pictures. Pretty much everything that went into the build to help make more power is pictured at some point in the thread, along with detail shots of the cylinder head ports, the inside of the intake manifold, a look at the suspension setup out of the car, the incredible wiring effort and, of course, completed images of the car in the driveway and on the dyno.

LSX Cylinder Heads

Speaking of the dyno, towards the end of this picture-heavy thread, the OP shares that his Firebird made 950 rear wheel horsepower at 11 pounds of boost with some tuning issues. Later on, he points out that the car eventually made 1,028 horsepower and 853.9 lb-ft of torque at the rear wheels on 11 pounds of boost in his LS-powered Firebird.

Again, there isn’t a whole lot of discussion about the build, but if you like looking at a “build in pictures”, the Project Blackbird Firebird thread is a great way for you to kill some time at work.
