Today we tested the Mazda RX7 | Spirit R on a very busy track day. Lovely raspy engine and the car handled well... to a point. Watch to see if we can get our first official valid time on Youtube.

Mazda RX 7 info:-
(Evo.co.uk) Today the RX-7 is a rare beast, especially one that has been untouched by the greasy fingers of backyard tuners, but find one with a good history and sensible previous owners and the rewards are considerable. There is a caveat with the RX-7 though, as with all rotary-engined Mazda’s, the RX-7’s highly-strung engine not only requires lots of TLC to remain healthy, but also cyclical engine rebuilds thanks to the deterioration of rotor seals.
Featuring a sequential twin-turbo setup, the RX-7 employed just the one turbo at lower engine speeds to increase response, with the second only coming into play above 4000rpm. Although it reduced turbo-lag, that very 90s of issues still plagued the RX-7’s rotary engine, chiefly due to the engine's natural lack of torque. The other compromise of the turbos was the loss of the previous RX-7’s dizzying rev limits, this time the motor was limited to a relatively normal 8000rpm.
Launched in the UK in a single high specification to rival the Porsche 911, the RX-7 cost a substantial £32,000 in 1992, but after a year of slow sales, Mazda dropped it down to £25,000. UK cars were set up with the stiffer suspension and strut braces of the Japanese market R model but the second hand car market has subsequently been flooded with privately imported models, making it difficult to pin down the specific specifications due to the endless confusing Japanese model variants.
It’s a genuinely enjoyable engine; torquey with little lag, it delivers a solid shove from 3000rpm through to 6000rpm. Beyond that it runs out of puff a bit, yet still pulls meaningfully to the red line – signalled by the infamous buzzer as a reminder to take another gear. If you’re remotely intrigued by a car’s oily bits, the RX-7’s motor is special. It doesn’t dominate the whole character of the car, but it asserts itself nicely and sets the tone for a driving experience that’s outside the norm but delivers the goods.

The balance is beautifully neutral, with just enough bite from the front tyres to generate decent grip and response but not enough to induce oversteer. Likewise, the rear end has strong traction – not a surprise given the rear tyres aren’t exactly over-burdened with torque. In short, the perfect weight distribution and sweet ratio of grunt to grip ensures a harmony that lets the chassis work unhindered by dynamic imbalance. That it’s not fighting with an engine that’s too potent underlines the fact that sometimes less really is more.
