I finished my second project car with the help of HPA!

I have always wanted to build cars and customize not just the look, but also the performance and functionality. I just finished my second project car, a 2021 Dodge Challenger Scat Pack 6.4L. I upgraded the cam, added the phaser limiter, upgraded the springs, replaced the lifters and pushrods, a new mishimoto radiator w/ 180• thermostat , ported the heads and intake manifold, upgraded the throttle body, installed kooks long tube headers and high flow cats, and did various repairs (as I bought it as a salvage car). I’m attaching a few photos of my work. The video is from the Dyno session. It was done by National Speed in Wilmington, NC. I am learning the EFI section from HPA now, so my next project I’m going to attempt to tune myself.

The video was too large but here's the dyno sheet.

Congrats. It's a great feeling to see the final result working. Nice built.
