If you guys want to run big boost, you are going to have a hard time short up running a turbo that is capable of running higher pressure ratios efficiently.
Shiv did you guys ever get the RB cars you were looking for? What kind of results did you get? Have you tested rbs with the flex fuel kit yet?
