HOT LAP POV 4 ROTOR Turbo Sequential RX7 Barber Motorsports Racetrack! Wicked LOUD

Mazzei Formula Seven, piloted by test driver, Bryan Longshot Leonard on Barber Motorsports Park Racetrack. Testing the new sequential air shifted transmission and brake package! listen to this glorious shakedown, over 110db of rotary !

[@Slowcarfastbeans]

For cars that have straight line acceleration as their predominant strength, road courses are just drag strips with turns at the beginning and end. The problem solving is how quickly can you straighten the wheel before trying to use all the power…and most high power cars are either a lot of power or none.

[@H8er-Maker]

@@Token_Black_Guy I like Rob's cars but that AWD basket case is made from more Subaru, GTR & 1 off custom parts than Mazda parts on it. I realize that this doesn't have much Mazda left on it either but it still looks like an Rx7. Checkout Defined Autoworks channel he has a nice 1 also.

[@natorious314]

@@H8er-Maker Hard to build a dream car from manufacturer correct parts when the manufacturer doesn't make parts to meet your needs. It's definitely a basket case, but at least it's built for the love of the car. Dude has probably created as many rotary fanatics as Gran Turismo did with putting our butts in a 787B.

[@JDub33333]

Sounds like 90s F1 mixed with 80s Le Mans. This is epic.

This car is hands down my favorite build on KZbin! I keep a screen recording of your first dyno session with the air shifter just to go back and watch every week or so, I literally watched it six times working overnight a couple of hours ago (was showing it to some fellow enthusiasts who were shit talking Mazda lol)

[@von...]

hey, you should help Rob brainstorm what kind of body he should build for his 4 rotor build! Between you finishing your cars and being close with the defined autoworks guys I think you have some good experience with functional, but aesthetically pleasing, design choices. btw this video was insane and I love how you get pro drivers to shakedown your car, knowing that they will give you the best feedback to improve upon. I am also hyped you are at the point where its going to stop being shakedown track days and instead be just dialing in the setup :)
