I met up with toofast4u over the weekend with his insane 03 Sonic Blue Cobra sporting a new Kenne Bell Blowzilla at 17 psi. Short, but sweet! He states he made 600 rwhp. Enjoy.
That thing sounded meaner then I thought it would. In person, it sounds mean as hell! He broke the tires loose at 45 mph with 315 Nittos on the back. Pretty sweet.
