Z1 on the Top Gear Test Track?

28 Nov

Well, kinda…read on.

If you’re reading this, chances are you own or have owned several modded cars over the years. I’ll go out on a limb and guess that most of us enjoy our cars in daily driving and rarely (if ever) see a race track.

Thankfully, Forza 4 for the xbox 360 is packed with a large variety of detailed cars, mods and a lifelike physics engine so you can enjoy some of your present/past machines on the worlds most famous tracks.

I was able to build our old, sadly missed FC RX-7 and it’s accurate down to the rare Mazdaspeed front spoiler. With identical mods, the total power and power-curve are shockingly accurate.

Even more impressive, the game even realizes that one cannot perform traditional “headwork” on a Mazda Rotary engine.  Rather, the game allows you to select various levels of intake/exhaust “porting” options just like a real Rotary engine builder would perform.  Our setup was simple; street intake and exhaust mods, a street port, an upgraded fuel pump and ECU, and a large front mount intercooler for the stock turbo. The results are around 300 horsepower and 275 lb feet of torque; plenty to push around a relatively feathery 2600 pound car.  I even added an adjustable final drive set to 4.30 to simulate the coveted 1989 RX-7 GTUs unit in our old car.

Finally, I did some research and found the actual spring rates from our coilovers and the anti-roll bar sizes, rim diameter and tire sizes to match the game setup to that of our real-life car.

With our virtual car completed, it’s truly a blast to take a spin around the famed Top Gear test track, or try to tackle the corkscrew at Laguna Seca.
