Rotary 20B turbo RX7 - Dyno & track
Built as an all-round event's car, Charles' Mazda RX-7 has undergone
serious chassis and engine changes including a Promaz Automotive
bridge-port 20B rotary engine. Boost
comes from a Garrett turbocharger while
the engine runs on methanol fuel controlled by a MicroTech LT16 computer
and LTC dash logger. Backed by a Jerico 5-speed dogbox, the clutch was
suffering on the Dyno
as the Promaz team got the car ready for Performance Car Mania. [

At this speed, the tire patch that is touching the ground is LESS than the
width of your index finger across each tire.
Furthermore each patch is encountering dust and small sand-like particles
often. If you could keep the pace with this car and remain standing next
to it, you could reach over and push it away from you sideways with little
The announcer claims that an additional burst of oxygen in the fuel causes
a loss of control, but in all likelyhood, the wind just changes ever so
slightly, or began to blow (even lightly) and it was actually this that
nudged the cars nose off by just enough to start a flat spin.

ALTERNATE VIEW This video is to show how a well maintained RX-7 idles when
cold-started. It will first idle at 3,000 RPM for about 10 seconds to build
oil pressure. Then it will drop to 1,500 RPM for about 15 seconds to warm
the seals. Then it will drop to 600-750 RPM resting idle after about 30-45
seconds. Car is fitted with a K&N Cold Air Intake with heat shield and a
2¼" High-flow Cat-back dual Exhaust
system. The smoke from initially starting it is normal. The engine does
this to lubricate the apex seals when the engine is cold.

'88 RX-7 SE - Racing Beat exhaust
I installed a used Racing Beat Exhaust
today. I took video of the car with the catback removed (just the
presilencer), and with the new Racing Beat Exhaust installed. Sorry for the video quality
and background noise, my garage is on a busy street and I'm still working
out the details of using this camera with high contrast scenes.

to a Mazda RX-7
