Cadillac Attack Ohio 2025

We had a great time at Cadillac Attack Ohio 2025.  Congratulations to our long-time friend Tim King on setting a personal best time and new world record with his Cadillac CT5-V Blackwing.  Tim set out to be the first CT5-V Blackwing with the 10 speed automatic transmission to run an eight second quarter mile time with full weight down to the floor mats, running a completely stock motor, transmission, converter, and driveshaft on an 18 inch drag radial tire.  Tim made several eight second passes, including a best of 8.91@158mph.

We also want to also congratulate Jorge Munoz on some very impressive times, set at the Cadillac Attack Ohio 2025 track rental this past Thursday.  Jorge was able to run four full passes with three of them in the in the 9.7s @ 141 to 142 mph.  His Brown Belt Performance Package is a strong and consistent performer allowing him to made three passes in a row with 1.38 60 foot time.  Very impressive in the summer heat with density altitude numbers of 2,500’ and higher!
