Regular readers might recognise this curious car. We talked about it back in February, and yes, it’s a Mazda MX-5 brandishing a 6.2-litre Hellcat V8 under the bonnet. Actually, the massive motor is too big to fit under the MX-5’s bonnet, but as you can see in this latest video, it’s not too big to fit the confines of the Mazda’s engine bay. That is, without some extensive modifications to wedge the supercharged mill in there.

Previous build videos from KARR on YouTube chronicle the progress of the bonkers engine swap, but the newest clip from Florida Car Culture shows the end-result, and what can be said that hasn’t already crossed your mind? A 707-bhp MX-5 is well and truly capable of obliterating tyres with reckless abandon, though to be fair, that engine in anything short of a semi-truck can atomise rubber with relative ease.

This smoking demonstration took place recently at Bradenton Motorsports Park in Florida, and we do mean recently. The first firing of the Hemi V8 was posted to KARR’s YouTube channel less than a week ago, so we’ll assume this burnout exhibition was the first major appearance for the FrankenMiata. The smoke show starts off a little slow, but then the driver hands over the controls to noted YouTube car guru and engine swapper Cleetus McFarland for some follow-up action. He doesn’t tread lightly on the accelerator, and by the end of the run, we’re not sure if smoke pouring from the engine bay is residual tyre smoke or something a bit more dire.

MX-5 engine swaps aren’t anything new. Since the sports car’s early days folks have dropped bigger mills under the bonnet and, to be honest, even the torque from a mild V8 turns the MX-5 into a crazy smoke machine. Considering the 6.2-litre Hellcat offers up six times the power you’d get from a standard MX-5, we hope the builder of this wild ride has a healthy stock of tyres on standby.
