The Ferrari FXX Evo is the ultimate track car. But the problem is Ferrari keeps them on the circuit, in fact they don’t even move and there’s no chance you could get one of these monsters on the street. It just wouldn’t happen, unless you take the base Enzo and make your own, that is.

Edo Competition is a fast growing name thanks to his work on Italian exotica from his base in Ahlen, Germany. He had a 6.3-liter Ferrari FXX engine fitted into a 599 long ago, and he has given a good few Enzos a boost in the past. When Canadian Zahir Rana of ZR Auto went into business with Edo he wanted the ultimate car for himself, so the yellow Enzo that starred in his now infamous DVD is even badder, better and much, much faster.

Sadly it is not street-legal in Germany, and as we fire it up to take it out the garage the police arrive and stake out the car, it really is that loud. If it hits the public road, we’re going to have problems. But the estate itself? Well that’s a different matter.

It’s wet and Edo Karabegovic cannot truly put a price on the car, as the new back end moulding took three months and he’ll never make another, so there will be no heroics today. That rear end is an exact copy of the FXX Evo, produced painstakingly from photos and measurements, so it gets the same aerodynamic flips and monster diffuser. It’s where so much of the work went in, and it’s a work of art. There truly is no price on this car, but if you have hundreds of thousands to throw at your Enzo then the engine upgrade, clutch, new exhaust and suspension are yours from ZR Auto.

It whirs into life on the turn of the key and then comes the explosion of latent power, the noise is absolutely violent. And as soon as the police realized we weren’t going to hit the streets they left us alone, and we hit the 1km straight by the industrial estate. I can finally squeeze the throttle and with a slight squirm, thanks to the wet conditons, the Ferrari takes off.

From a standing start it will blitz the 100kph mark in 3.2s and it will hit 200kph in 9s and 300kph in 19s, on a dry day and the right road. Today isn’t that day, but a quick blitz down towards the first corner shows some serious grunt, acceleration and the harmonic yet hard edged Ferrari V12 racing engine.

Edo bumps up the displacement to 6.3-liters, fitted new camshafts, new titanium valve spring retainers and connecting rods, modified cylinder hears, exhaust headers, high flow catalytic converters, mufflers and air filters are all part of the supporting cast. The main trick here are the solid lifters that lets Edo rev the engine to an almighty 9600rpm. That’s a sonic boom of an engine, and it pump out 840bhp and 575lb/ft of torque in a car that weighs 100kg less than the standard Enzo, and that is a lot.

He’s ditched the old clutch, too, and built his own triple plate system, that means it will take standing starts all day long. It jolts just a touch more than the standard unit off the line but it’s bulletproof now.

KW Suspension from the MC12 Corse FIA GT car has given the car even more grip in the corners, with a lifter system that carried it across the broken carparks that we used on our shoot. Dunlop has jumped into the project wholeheartedly and is working on rubber that will go as fast as the car can, too.

Because there will be a record attempt before too long, Edo looks certain to break new ground with a roadgoing Ferrari. He’s refusing to name a speed, but don’t be too surprised if this car nudges through the 400kph mark when it hits the right track.
