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. [

20B ROTARY ACTION! 20B DATSUN 1200 & 20B MAZDA RX3 - TNT 28/12/2013
On the final Test and tune at Willowbank Raceway for the year, Brad Mcilroy
was out testing his Mazfix prepped 20b Datsun 1200 ute as well as Russ in
his 20B powered Mazda Rx3. The PRODAT was testing some changes in the rear
end, keeping the newly added 10.5 inch tyres as well as some changes to the
4 link, and after a few tweaks had the car complete a full pass of 7.95 @
165 mph with a small back off down the deep end, a little slower then what
the car has run but a little more stable down the track. The Mazda Rx3 had
some issues most of the night but managed to get it down the track for an 8
second pass, also off its best, but once sorted should be back down to
where it was running before.

20B rotary RX-7 Spirit R: The Ultimate Street Mazda
Built by Promaz Automotive, we think it's hard to go past Steve's wicked
Series 8 FD RX-7 if rotaries are your game. Limited to around 1500 unit's,
the Spirit R was the last of the RX-7's and featured a lot of upgraded
factory parts as well as a low 1100kg weight.
Now powered by a lethal Promaz triple rotor 20B extend port rotary engine,
power is aided by a Garrett GT42R turbo
and MicroTech fuel system and transmitted through an Albins 5-speed gearbox
and KAAZ rear end [ http://www.promaz.com.au ].

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.
