Here is the blown 340 in my challenger. The motor went together with the blower in 1998 and is still going strong! It was originally carb'd with X heads, but has had edelbrock heads on it since 2000 and EFI since 2001. This is a old pic, and its kinda ugly, but it only has more miles and ugly on it now. I've run it as high as 15lbs, but my final tune on it is setup for 10lbs. All I got out of the higher boost setting was more tire spin and more broken drivetrain parts.
