26 PSI RX-7 GT35R Single Turbo
Ever wonder what happens if you hit fuel cut at 26 PSI on a turbo RX-7? Watch me do it on accident while
For those wondering, I had the ECU set to 20 PSI expectation and wastegate
to 26 PSI. ECU will go 3.5 PSI over its limits before it cuts the fuel.
Small logical error can make a huge difference.
I got lucky. I attribute a large part of that to the pre turbo water injection keeping my knock low and
combustion temps low while tuning.
Every gear is neutral on my RX-7 lol.
I blew the transmission on my 20B rx-7. Technically its not the gears
inside the transmission, its the output shaft penis thing on the end. You
can see it stuck in the drive shaft. I also (previously?) snapped the
spine of the car, the powerplant frame.
This is the stock transmission on a 750 hp car lol. i aint mad
What its like owning a 3 Rotor 20B RX-7
I have one of the most amazing custom RX-7s in the world. I want to share
my experience of owning and driving such a unique car.
I explain where the engine came from, why its so special, and what it does
to a Mazda RX-7
7500rpm on my single turbo RX-7
Flame away. I totally misshift my first pull. The second pull I hit the
overly rich area in my map. I can't give it full throttle. lol. Then the
good pulls. Enjoy
Mazda Rx7 4-rotor race car. The making of a Defined Autoworks Beast. [Offical Video]
Never before seen footage showing the assembly/start-up of our custom
4-rotor. It is the first 4-rotor since the 787b to use triple spark plugs
per rotor. It is also the first since the 787 to feature telescoping intake
manifold. Custom made slide throttle body system. A world first however is
the use of a center main bearing and 4-piece eccentric shaft. Quick specs-
9.7:1 rotors, lightened and race clearanced. Race main bearings, and race
rotor bearings, ceramic NRS 2mm apex seals. Custom stationary gears, Full
custom Peripheral Port in each rotor housing (defined auto), Aluminum side
housings for reduced weight. Needle roller bearing in the center housing.

Water injection installed and operational
My 1993 rx7 has a fully operational preturbo water injection system installed! I have to
install an inline fuse for the solenoid but it's amazing!
I'm running 15 psi until I install my 3 bar sensor.
