Jimmy Vernon & Carey McMahon's turbo tyro still has plenty of bite

This car is older than I am! Though I’ve been racing for quite a few years through different state and national categories. After I was getting some good results, Carey McMahon (who also races a De Tomaso) decided to throw me the keys to the Sierra.

I’ve just set a 1:39.3 lap time, which I believe is a new record for the class. (This is for Group A Touring. Mark Skaife previously set it at 1.40.2, in a Skyline back in 2013 – Ed.)

The Sierra is really nice to drive and really opened my eyes to the technology they had back in the 1990s. I’ve driven a quite a few late-model cars in recent times, but jumping into a real raw race car that some of the legends of our sport were racing is just awesome.

I noticed some little things, like the car doesn’t produce much downforce. At a track like this, where the speeds are quite high through the corners, you do notice a little bit of instability. But the car still does everything you ask it to.


The power down is aggressive but nice and the car rotates well – it’s just a really good package. It is aggressive and feels like it’s going to throw you out the back window when it gets going.

Ed’s note - The Sierras in original race form had a reputation for being challenging to drive. Our 2013 feature with the legendary team owner and driver Dick Johnson had this to say about the 1993cc DOHC 16-valve Cosworth engine: "We used to run them in on the dyno without the turbo hooked up and flat out they made 90 horsepower. I kid you not. Put a turbo on it with 2.4bar of boost and it made 680 horsepower. And it used to come on like a light switch." Jimmy is now moving on to the recently-announced TCR Australia series as part of the Gary Rogers Motorsport crew and is looking for additional sponsorship.
