We connected our new Brown & Miller Racing Solutions (BMRS) PTFE vacuum line to the billet adapter on the intake manifold.
We connected the other end of the vacuum line back into the factory rubber vacuum hose just before the 1-way check valve. Overall, this brake booster vacuum solution looks significantly nicer than the factory rubber hose, and will hold up to far more vacuum.
After installing a temporary K&N air filter, the new DBW intake manifold is now ready to go with our 80mm Mustang throttle body.
I was extremely excited to now have the ability to determine the curve and response of the pedal to adjust the throttle sensitivity for drivability, heel-toe downshifts, and overall control. Having been a part of the throttle calibrations of most 2015+ S550 Mustangs for Ford (including the Shelby GT350, GT500, and even Ford GT), I couldn’t wait to dial in the pedal calibration for the NSX, which is one of the major benefits of going to a DBW setup.

Very clean installation.
I like it when modifications are thoroughly thought out.
Any plans to replace the fuel rail crossover hose? Those get nice and crispy after 30 years of use.
Yes, the entire fuel system is going to be replaced and upgraded in a future article. Stay tuned!
This project is heating up! Excellent work and execution. I can’t wait for the next update.
So sick, bro.
I’d love to see an article about DBW and throttle mapping!
We could do that; there is a lot of information on HPAcademy.com though.
Not that it is necessary with forced induction here, but wouldn’t independent throttle bodies eliminate the space issue entirely? Gorgeous work either way.
While ITBs would eliminate space issues, it will cost (depending on which brand ITBs) $10K – $15K – $20K or more to have a DBW ITB setup with a custom plenum for forced induction. Our solution of cutting the stock intake manifold, making a billet adapter plate and used Mustang throttle body was around $500.
