2008 Mustang Roush 427R Dyno (Detroit Rocker Cams & Headers) at Brenspeed 490R Package 9PSI

The Roush 427R is a great car. Although the M90 is not capable of massive power you can upgrade it and have a VERY FUN tire shredding street car. The torque comes in fast for sure considering you are working off of a 3V platform. Need an install quote? Email quote@brenspeed.com we are located in Indiana.
