Turbo 4 Rotor RX-7 SCREAMS on the Dyno | Mazzei Formula

David stopped in to Abel's shop to get his 4 Rotor tuned. Listen to the difference from start to finish. You can really see how our builds contrast and benefit from working together to keep pistons out of RX-7 shells. Davids IG: mazzei_formula

vullut The FD weighs nearly 1.3 tonnes. I ran mine at 430whp it was a good happy medium for a 13b, it was fast, fun and manageable.. If you go for much more power, You're getting into the territory of big laggy turbos, and RX-7s need all the low end power you can get since it has about as much torque as a pensioner with arthritis operating a screwdriver.
