The Mazda RX-7 is a front-engine, rear-wheel-drive, rotary engine-powered sports car, manufactured and marketed by Mazda from 1978 through 2002 across three generations, all of which incorporated use of a compact, lightweight Wankel rotary engine.

2023年3月9日 · A stock 93 RX7 will rev to 8K. On stock ports there’s no increase to the power band after that so not much point. I’m sure a street port will increase what you can get out of it at higher rpm, but it really depends on the size of the port and if …

2021年12月6日 · How does it effect performance, and stuff like gas mileage, weight, and the iconic high-revving character a rotary engine has? It depends what you're using it for. It will almost certainly make less power than most 2 rotor engines, unless there's something really radical going on with the porting.

2019年12月3日 · Aided by a Work GTX5593 98 mm Gen 2 turbocharger, the car now produces a neck-snapping 1,000 HP and 650 lb-ft (881 Nm) of torque and revs through to 10,000 rpm. This video offers a taste of the...

2024年11月5日 · Throttle response is smooth, and you’ll enjoy exhaust notes through the RPM range, which redlines at 9000 revs! One might doubt the handling of a Mazda RX-7, but the double wishbone suspension, low ride height, and lightweight chassis make it an easy-driving car even at high speeds.

2016年4月9日 · Who revs up before shutoff? I usually rev up to about 5k 3 times and cut the engine at 2500rpm when it's revving down. People tell me it's better to hold at a steady 3k for 10 seconds, but I like the sound when it hits 5k.

2020年12月1日 · Few vehicles sound quite as remarkable as a Mazda with a high-revving rotary engine and this RX-7 is perhaps one of the most incredible in the United States.

2015年8月6日 · I can't seem to get the car to rev past 6000 rpm under load, no matter how much fuel I pull from that area of the map. It seems like a misfire or soft rev limiter, but I'm not getting any sync loss or cutout on the tach. It will free-rev past 6krpm (the revs to ~7k in the data log are with the clutch in)

2003年2月25日 · I think I have figured out the how and why of idle speed control for the RX-7. The ECU needs to determine when to enter the "lean best idle" mode. It looks at the clutch status OR the neutral status to determine if the engine is connected to the wheels, (basically does the engine have a load attached?).

2009年4月22日 · 87 rx 7 rx7`s should rev to 3000 when started cold then it should settle to 750 to 1000 after about 30 to 60 seconds. mine suffers a similar problem. so far I have been told various answers, mostly involving the bac valve, lambda sensor, air flow meter, etc. try starting of by adjusting the idle adjust screw (on top of the throttle body under ...
