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. [

12 Rotor Engine Running- Different Angles
Watch the last part of the video where there is a glass of water on the
engine. The engine runs so smooth it does not even ripple the water.
Looking at the glass on the back, you are seeing the reflection of the Exhaust tubes bouncing on the flat
surface of the water. The water actually does not even have a ripple.

Sick RX7 Takeoff - LOUD
Orlando Cars and Cafe - Watch and Listen to this highly modified Mazda RX7
take off. Originally was filming another car but heard what sounded like
gun shots. Turn around and see this 600+whp RX7 just backfiring like crazy.
Watch and listen as he gets absolutely no traction in first gear and then
just rockets off.
The car was putting down 600rwhp @16PSI of Boost with the potential to put down 800rwhp
at 27PSI on race gas.
