We’re currently searching for a volunteer to have the first ever CT5-V Blackwing cat-back exhaust system. You will need to have a CT5-V Blackwing (with either A10 or M6 transmission), and still be running the factory catalytic converters. You would need to drop your car off near Cleveland, Ohio...

We installed a ported supercharger, ported throttle body and GPI cam package on this CT5-V Blackwing . It already had a set of Kooks headers installed as well as a custom cat-back exhaust, but needed a little more bite to go along with the bark.After completing the parts installation and getting...

There are a lot of CT4-V Blackwings out there without the CF1 and/or CF2 carbon fiber packages. These cars have black plastic front spoiler pieces, one on each side. I believe the CT4 and CT4-V might use the same parts. Will have to verify. Does anyone know what these are called? And who...

Now that HP Tuners has granted us access to tune the E99 Global B ECMs, we’re finally able to tune these cars to the nth degree. Check out our latest 747 whp dyno chart, running Brown Belt Performance Package on E65 fuel plus methanol injection. New parts recently added include the ATI Super...

This week we completed CT4-V Blackwing Blue and Purple Belt Performance Packages in house, tuning with the newly released HP Tuners access to the Global B ECMs. First chart below is a Blue Belt running 93-octane pump gas. Notice that our tunes don’t just hit the peak power number for 50 or...

It took our team more than one year to hit 700 whp with the CT4-V Blackwing. The CT5-V Blackwing should easily cross that threshold next month, on pump gas, only two months into the process. We did four baseline runs over the last 15 days, ranging from 614 to 621 whp on a DynoJet with SAE...

Our new carbon fiber intake system for the CT4-V Blackwing is a work of art. And it also performs! Internally, this revolutionary new airbox design functions in a proprietary manner that increases airflow and boost, without the ECM being aware of the changes. If you bolt this intake to your...

We just received an early production piece of the soon to be released Tapout Tuning carbon fiber intake lid for the CT4-V Blackwing. We're currently in search of a CT4-V Blackwing owner close to central Ohio who is willing to let us test this first piece on his/her car. If you're interested...

Charley had a good friend drive his car up from Florida to our shop in Ohio for the Blue Belt Performance Package. After installing Green high performance air filters, Gigs ported throttle body, Brisk silver racing spark plugs and Tapout resonated downpipes, we strapped the car to our DynoJet...

The first step in putting our flagship CT4-V Blackwing into the nines was to add 300 horsepower. We crossed that bridge a couple days ago. The second step is figuring out how to launch the car under boost. Our team is making progress on that front as well. Crank up your volume and enjoy!

What takes 15 months, 11,000 street miles, 228 dyno pulls and eight track days spread over Florida, Texas and Ohio? Crushing the 700 whp barrier for the first time ever with a CT4-V Blackwing. Today we reached a new milestone with the Brown Belt Performance Package on our flagship car when it...
