Mazdaspeed 3 BNR S4 Acceleration / Sounds
In this video, we get some sights and sounds of the MS3 with the Bnr S4 turbo, Cnt Racing catted downpipe, and stock catback with two resonators deleted. This will be the last video with this Exhaust setup because it has proven to be a restriction at 22 psi or higher, robbing horsepower and causing knock. The car has been de-tuned to approximately 300 whp at 19 psi for safety until the new Cnt Racing catless turboback Exhaust system arrives in the mail. Then we'll be able to start running more Boost and make more power efficiently. If you enjoyed this video, please Like, Share and Subscribe! Thanks for watching:) Mods in this video: 1.
