My mazda Rx7, has a 12a peripheral port motor, with a modified nikki carb (the carb it originally come with) It still needs a bit of tuning, its a little bit lean at idle and on the primary circuit, so Ill get that sorted in the next few days, got a bit more power than the motor when it was just extend ported! I will eventually put an IDA on it but will run it like this first at the drags and see what we can get out of it!
Rx7 Shakedown at Gingerman Raceway
Just a couple shakedown laps with the new clutch/flywheel/miata trans
installed in our NASA PTC/TTC Mazda Rx7. This was at gingerman raceway
during a thursday test and tune. The fastest lap of the day was in the
high 42's. Once all of the issues with both driver and car have been
resolved it should run somewhere in the low 38-high 37 range.
The Gingerman Test and Tune days are an amazing value, if you are ever able
to do one we would highly suggest it. Very relaxed atmosphere at a very
fun and challenging track. Just kinda hang out and beat on your car

On this episode of Ignition, Carlos Lago convinces Mazda to hand him the

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. [
