This episode we feature Roy's 1150WHP 4 Rotor Mazda RX7 and it is without a doubt the cleanest 4 Rotor RX7 street car we've ever seen! We had the pleasure of filming a full dyno session and then took the car for a few rips around town. The 4 rotor screams to 9,000 RPM and surprisingly spools the 91MM GTX turbo very nicely. Paired with the S1 Sequential shifted faceplated t56 trans this car makes all the right noises! We're going to follow this build as they continue to dial in the setup so stay tuned...
