  6. James Sims


  7. Ross Hamilton

    Ah man I wish I had known you were here!

  8. That Auto Garage

    That’s so heart warming, you’re the man Brent!

  9. GordoWG1 WG1

    As an old-school carbie guy, checking the vehicle was actually getting full throttle is one of the first checks I made - had some with a 1/2", or more, slack which made my tuning efforts even more noticable to the customer when it was taken out 😉

  10. Thorn Matthew

    So amazing to witness the enthusiasm in this group of young men. Great job sharing the knowledge and fostering the next generation of gear heads. ⚙️

  11. Jared Spear

    Awesome job Brent and Jamie! Teaching the next generation is always a blast and a great public service. These young men will never forget the experience they had building this car and then tuning with PFI!!

  12. Brayden

    Wow that made a lot or torque!! I wish the PFI dyno would read torque properly

  13. Joshua Knowles

    Welcome to VA Brother!!!!

  14. Redman147

    Brent's laugh is contagious. I'd love to see more videos like this. Spreading knowledge and seeing young minds meld into one to accomplish a single goal for their school and themselves.

  15. Redman147

    VA Tech on point with getting parts they need. Almost like Brent's back in his own shop. So smooth with all the work. Boys on point. Hope they do well in their race.

    I wonder if these kids realize this will be the best automotive memory of their careers? .. and if it isn’t - then they will be killing it. I’m rootin for em. We need more mechanics and automotive professionals.
