  3. Has anyone received/tracking info on Whipple kit ?

    I understand. When I get these updates I speak directly with Dustin. Being that we're longtime friends I can get in touch with him easier than most.

    Hey Guys! We took our Whipple Supercharged 2024 Mustang GT to the track to see what it would run. This car does have the manual transmission so we knew it was not going to be as easy as our past vehicles, like our 2018 Mustang GT Project Goldmember, which went mid 8s. Jared was a little uneasy...

The closed valves do lessen the sound, significantly, but it is still louder than stock. I would put open valved at 8ish/10 and closed 3-4/10 where stock is 2-3/10. We have plenty of...
  20. So how do we think a stock car is going to hold up to the Whipple kit?

    Here's Igor's 2024 dark horse with the 10 speed automatic. He's been beating on it pretty often and drove it down from NC to put it on PBD's dyno to see how it would do compared to our MT82 GT. His car is 100% stock other than the Whipple stage 2 kit and it was running on pump 93 with no octane...
