1978 Mazda RX7 with a nikki carbed 12app

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!

My 12app RX7 on the dyno 166rwhp on a nikki carb
This is my 1978 rx7 series 1 on Top Speeds Dyno in Richmond Nelson NZ, It has a 12a peripheral port engine with the factory nikki carburator (modified a little) as the induction, When I drove it into top speed it was making 132rwhp and now it has 166rwhp and 153ft lbs torque so Im pretty happy with as these engines made about 87rwhp out of the factory, I will eventually put a 50mm injection perfection setup on it and it should gain alot more! But for now Ill put it on the strip like this and see how it goes, When the engine was extend port it was running consistant 14.4 seconds on the 1/4 and had around 110rwhp so it should go alot better now!





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 Car Specs: '83 Mazda Rx7 12A VERY mild street port (about 140ish whp, allowed 160 whp in my class ) Modified OEM Nikki carb 2400lbs with driver (allowed 2340 in my class) Miata Trans 225/45-13 Hoosier R6 Autopower cage 4.6 rear gear (stock is 3.9) welded) Tokico Illuma front/Tokico Blue rear Shocks Eibach Race Springs Ground Control front coilover kit Ground Control front camber plates 1 1/8" (28.5 mm) front sway bar/no rear sway bar Panhard bar Energy Suspension poly bushings Fuel Safe Fuel cell Urethane air damn and a bunch of other misc stuff

Testing the home made wotbox(flatshift/launch control) on rx7
Just finished my home made wotbox, I have used a megasquirt 1 v2.2 and used two outputs to drive a couple of relays which are in series with the positive side of the coil, one of them has an earth to the clutch switch so when the clutch is out it keeps the contacts closed on the relay, when you put the clutch in it disconnects the earth and the ecu takes control at whatever limit you set it too, in this video its 3500rpm, the second solenoid is for an overall rpm limiter, also using the shift light function of the ecu. The car is a 1978 rx7 with a 12a peripheral port engine with a nikki carb, Hopefully this will make flatshifting and launching easyier!
