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. [

while i'm busy fakeing my speedo :-)
READ THE DESCRIPTION BEFORE POSTING BULLSHIT
the speedo shows a little bit too much speed because of the shorter
real top speed at 13.500 RPM (removed limiter) is 291 kph.
all speeds are in KPH, NOT MPH!

RX-7 FD3S R1 - 422 HP - 504 HP - Dyno and Street Footage
This is a video of my RX-7 FD3S. It has 422 RWHP on a daily driving setup,
tuned by me. It was also recently tuned by Steve Kan, which got it up to
504 RWHP. At 422 to the wheels, it does the quarter mile in 11.8 secs. At
504 RWHP, it probably does it in the low 11 to high 10 second range,
depending on the tires and traction (duh).
Anyways, let me know what you think...
