Hey guys I currently have an 03 cobra with lethal return fuel system running e85, arp head studs , stock long block with 21k on it and a 3.0 whipple. Car currently makes 760 Rwhp and 676 rwtq at 23 psi. I am looking at doing the on3 twin kit and curious about peoples expierecne going from a roots blower to a turbo set up . My main use for the car is the occasional high way pulls and sometimes the track. Just wanting to know peoples thoughts and if they regretted going turbo. Any advice or experiences shared would be appreciated thanks.
