After 3 grueling weeks, the team at Boost Works is proud to announce that we have the world's first tuned, twin screw powered 2015 Mustang GT!

The car laid down a very healthy 653whp/533wtq at 12.5psi, at 17 degrees and .80 Lambda. We have logged over 30 dyno pulls, and around 100 miles of street tuning for drive-ability. It has been a challenge to say the least, but our team pulled through and got the job done. We've learned a lot about this new platform in the process, and we feel as though we have a firm grasp on the S550.

We did end up switching back to the stock throttle body, as the tuning software (both SCT and HP Tuners) lacks the proper tables to log and manipulate the parameters necessary to get the car running properly with a larger throttle body. So, even breathing through the tiny stock TB, we were able to pull out some very nice numbers.

For now, we will offer 2.8 liter kits, with 3.6 liter kits being optional for those who are looking for bigger power in the future. For now, both will be tuned on the stock TB. We will have a 2.8 liter car on the dyno when we get back from SEMA. We expect around 600whp on 93 octane as well. These Mammoth setups have so much potential! And, while we couldn't scrounge up any mammoth tusks, we did find something somewhat fitting.. :)

Thanks for sticking around for this build.. It's been fun! The car will hit the track soon on slicks to see what we can get out of it as it sits. Stay tuned!

93 octane.. Originally we planned on running around 15 to 16psi (around 725-750whp) which would have required c16 or e85. When we were forced to switch back to the stock tb from the 168mm big oval, it knocked the boost down to 12psi or so. At that level, we decided to try it on pump gas. We didn't see any knock on the dyno or on subsequent street pulls. We're at 17degrees, which is still pretty conservative.. I'm sure that has a lot to do with it.

I figured that's all they would need. Everyone is so quick to judge the IRS poorly, but it only needs a little work to fix the wheel hop. I can't wait until you guys get the tables to tune the larger throttle body to see what this thing can run on IRS.

I love IRS.. When set up properly, it's much better than a solid axle.

Took the car out for a spin today.. I've always been a turbo guy, but I have to see that these big twin screw blowers are winning me over.

The drive-ability is beautiful, and having nearly 500wtq on tap at the touch of the pedal is really nice. No lag, no waiting.. Just instant power. Car gets 24mpg on the highway at 75mph, and is a blast to drive.

We really couldn't have asked for more with this setup. Outside of R&D, the install was pretty simple. No oil lines, no crazy plumbing, or cutting on the car. Just bolt it up and go. :) With the advent of these big twin screw blowers, it really makes you wonder how much longer turbochargers are going to be in the mix on these big HP cars.
