After owning my ’93 RX-7 FD3S for 2 years, I decided to get a baseline dyno run at our SLCrotary Dyno Day. I purchased the car from a friend as a rolling chasis in 2008. My main focus for the car was to just have a reliable, fun, weekend cruiser. The car is “mostly” stock aside from intake and exhaust mods to help it breathe.

Here is a bit of information about the 1993 Mazda RX-7 FD3S as from the manufacturer via Edmunds.

It has the stock 13b-rew motor with the stock twin sequential turbos working almost flawlessly at 12psi. You can hear the bit of hesitation I’m trying to figure out during the primary/secondary turbo transitions in the video.

So, the final results were 244 RWHP and 211 TQ.  Overall I’m please with the results, and its right about where I expected.  With the factory specs of 255 HP and roughly a 15% drivetrain loss, that puts me about 30 HP over stock.  For the next year, my primary focus will be on getting it ready for the track at Miller, but inevitably, I will need more power.
