When visiting Whipple a few weeks ago I got the chance to see a few of the new compressors they've been working on. Not only did I get a chance to see the soon to be released 2.9L and 4.5L but had the opportunity to see them run the all new 4.0L compressor on their blower dyno. Art Whipple asked me to find him a low mileage 03-04 Cobra as he wants to be the first to sport the 4.0L on his own personal ride.
So here's what a 4.0L Whipple sounds like on their blower dyno. You think this is loud you should have only been there to here this baby scream!
