After a quick 1 week summer break Wind Tunnel is back with an eclectic guest lineup.

Dalton Kellett stops by as he and the rest of the IndyCar brigade get ready to tackle the Worldwide Technology Raceway this weekend outside of St. Louis. Kellett is part of AJ Foyt’s 2 car operation and when he’s not driving, this Canadian is on “Tick Tock” and other social media platforms encouraging youngsters to embrace the STEM curriculum.

15 year old Katie Hettinger  has already found her way into the record books at Hickory Motor Speedway. Her 5 late Model Wins at Hickory make her the winningest female driver in the track’s 75 year History! Jack checks in with Katie and gets the dope on what’s next for this young lady.

The acronym TRD stands for “Toyota Racing Development”. TRD’s David Wilson drops in and  explains why Toyota was the first OEM to jump headlong into driver development.

He’ll also share his thoughts on Toyota, Ford and Chevy’s collaboration in the NEXTGen Cup car as well as why the upcoming NEXTgen engine package will offer OEM’s some leeway in spotlighting their individual technologies.

All that plus a recap of the past weekend’s racing action.
