The Mazda Rotary Engine Part 1
Educational film by Toyo Kogyo about the Mazda Rotary Engine. Shows how the
Rotary engine works with comparisons to the Piston Engine. Also shows the
Mazda RX500 test vehicle on a banked circuit and the Mazda Cosmo Sport (or
110S). Originates from the late 60's.
In honour of the re-union race at Mallory Park this coming 28/29 August
(get your butts down there!) here is the tiny bit of footage I have of
Thundersallons/Silhouette racing. I loved these cars and races as a
marshall, well behaved drivers, spectacular cars, fast and noisy, just what
First clip has Tony Sugden's Skoda and Mick Hill's March BMW (anyone
confirm/disagree?) arguing over the same bit of Thruxton tarmac, big spin
for Tony. Next its a Class-B Silhouette race at Brands and a fast starting
Toyota Sarlet knuts the Brands bank. Then off to Donington and a race I was
at, hence the brief pause, that's me on the wall on the right. The cars are
Pete Steven's works Carlton leading from the Wilson/Birley Armour-All RX7,
Whale/Hodgetts ex-BTCC Supra (now with a proper gearbox, lol), Wallace
Sierra ?, Dell/Boarer Sarlet, Maries/Nash Holden, Chatfield BMW M3,
Jackson/Liles Astra, Morris/Morris 309GTi, Morton & Bridger/Mortlock
Sarlets, McLaird yellow 205. Awesome cars. The Cunnigham/Chalmes Manta
spins at Redgate and gets a whack from John Quartermayne in the SD1, then
Morris spins the 309. Stevens lost the race to the RX7 when a wheel
bearing went South, hence all the smoke.
Next its Brands and a rear view from the Stevens GM Carlton of Ron
Cumming's Aberlan Honda Legend, I remember Tony Wolf running a white Legend
as well, same car different owners and paint? We then see a very rare spin
from Stevens when he has to slow to avoid the ex-Sean Walker BTCC Sierra
RS500. Anyone else have footage of these awesome machines, let me know, and
see you at Mallory next weekend.
'The Godfather' 20B RX3 on the Dyno at Pac Performance
After carrying out a full rebuild on Sam Sadek's iconic 20B RX3 coupe the
time is now nearing for the car to make its comeback to the race track.
We strapped the car onto the Mainline Roller Dyno last night to give it a bit
of a tickle and she put down an easy 1100rwhp...
We can't wait to see Sam enjoying this beast once again on the strip!!
MAZDA RX7 Rotary Engine, How It Works
MAZDA RX7 Rotary Engine, How It Works
The MAZDA RX7 rotary or Wankel engine is a marvel of engineering. It has
won more races than any other vehicle in its class. Rotary engines develop
a great deal of power for their weight (power to weight ratio). They're
also able to develop high RPM bursts like no other internal combustion
engine. Learn the details of it operation, how the rotor transfers power to
the output shaft, what it the stationary gear set, what is the rotor to
output shaft ration and relationship. Get all the specifics on the rotary
engine's operation here in this video.
Presented using advanced software CG animation technology to help you
understand. Part of our Automotive Technology Rotary Wankel engines and
MAZDA RX7-RX8 series shown here on this channel. Enjoy...

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. [
