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. [

Why I picked the GT35R for my RX-7 over the stock twin turb
I cover the basics of turbochargers in
simple terms to explain why I chose the GT35R over T04Z or T78 or T88 etc.
It's all about air flow. Sure there are technologies that make the turbo more efficient in more applications but
the turbo is most efficient in an area
known as the compressor map.
Exhaust back pressure plays a huge
part when dealing with quick spool small turbos.
Large turbos deal with spool up and lag
I chose the GT35r for near stock spool up with more efficient 400 hp

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.
