FC THROWBACK: 640BHP MINI SUPERCAR SLAYER

Welcome to this week’s FC Throwback, where we take a look back at some of our favourite previous feature cars. This week it’s 1320’s MINI from way back in 2014…

A road-legal 1.6-litre, front-wheel drive MINI that can out-accelerate a Bugatti Veyron… impossible right? Wrong.

The Bugatti Veyron is easily the most famous fast car in the world, and understandably so. It’s a record-breaking monster, and with an eight-litre, sixteen-cylinder, sixty-four valve, quad-turbo engine, it’s got to be almost untouchable, right? Well, almost.

Most other supercars certainly can’t get close to it. Where as a Lamborghini Gallardo will run a 1/4 mile drag strip in around 12 seconds at 125mph, a Veyron would do the same in just 10.4 seconds and hit just under 140mph in the process. What can get close to it however (in fact it would be the Veyron that would be playing catch up), is the car you see on these very pages – this cool looking, but surprisingly normal, MINI.

Let’s be honest, most people wouldn’t expect a common, small-engined hatchback to match even the Lambo, never mind the Veyron. But ‘most’ people would be wrong, as UK-based MINI nutters 1320 MINI have proven with this hypercar-killing super-sleeper.

This car’s life began almost ten years ago, when 1320 picked it up as a fire-damaged MINI One from a salvage auction with the intent of having a bit of fun with it. The car was quickly repaired, fitted with the supercharged Cooper S engine, a Quaife diff, and a set of drag slicks, and instantly bashed out a 15.5sec 1/4 mile at 86mph on the strip. Which while miles away from the speeds of the aforementioned supercars, was still faster than a production Cooper S.

As the years passed the car was gradually tweaked and got faster and faster on the strip, and even did a stint in the Time Attack championship in 2010. But fast forward to 2013, and it was time to get serious.

Many would suggest you’d need an engine swap to something much bigger than the single-cam 1.6 MINI lump, maybe even a four-wheel drive conversion for traction. But the guys at 1320 wanted to keep this car as a true MINI. The engine is still running the standard block and crankshaft – albeit with Wossner forged pistons, steel rods, CatCams supercharger cam, and highly modified cylinder head. One thing it’s certainly not is naturally aspirated like a standard MINI One. It’s not even got a little supercharger or turbo like the hot Cooper S models. Instead it runs a flippin’ massive turbo – a Forced Performance GT3586HTA billet turbo from Owen Developments, complete with trick Tial turbine housing.

1320 really is a one-stop shop when it comes to MINI tuning, and they’re expert fabricators too. This is evident from the amazing manifolds – an equal length tubular exhaust manifold, which sits the turbo right over the gearbox, and an alloy inlet plenum complete with internal trumpets, and a 3in drive-by-wire throttle body. More of 1320s fabrication skills are evident with the massive, ice-filled chargecooler that keeps inlet temps at bay, and custom alloy header and oil breather tanks.

Finally, a set of huge 1350cc ASNU injectors feed the engine under the control of a 1320 ECU. Fully mapped in-house, the final result is claimed to be around 640bhp at 29psi boost, with the engine revving way beyond 9000rpm and loving every minute of it. There’s more power to come too…

It’s all well and good having power, but big power and front-wheel drive usually means massive, uncontrollable wheelspin, rather than rocketing off the start line, so how does this MINI do it? Well, the most obvious things are the 15in M&H drag slicks they fit to the front on the dragstrip (instead of the 16in tyres they run on the road), but one thing that never changes are the flat black Rota Slipstream alloys.

They’re not only light for maximum performance, but suit the car’s super-sleeper look perfectly. Amazingly for a front-drive drag car, it hasn’t got the weird stance you’d expect, with massive tyres sticking out of the arches and a jacked-up rear end. In fact the car looks damn good with a low ride height and the wheel and tyre combo sitting perfectly in the arches. Even the suspension is amazingly normal, with rear springs set very stiff to prevent the rear-end squatting down, helping give maximum traction. And while there’s certainly a few other little suspension tweaks, the car is still simply a modified road car.

Considering it’s pushing out nearly four times the power of a standard Cooper S, it’s amazing that it runs a standard Cooper S gearbox – albeit fitted with a twin-plate clutch, heavy-duty driveshafts and a Quaife ATB diff to improve traction. Running a standard gearbox is one thing, but most powerful cars smash gearboxes every other week. But 1320 have discovered the Cooper S unit is freakishly strong – the current ’box has been in the car for around six years now!

The final thing that helps this car get the power down is the ECU. It not only features two-step launch control – which gives them the ability to launch at full throttle at the perfect rpm and boost pressure for the ultimate acceleration – but boost is automatically increased as they blast down the strip. This allows them to run the engine right to the limits of traction, and give the full 29psi boost the moment the car has enough traction to put it down.

Outside, the MINI is totally in contrast to the usual wild and garish drag cars, but it’s all the better for it. While it looks great in red with the black highlights, a closer look shows how well the performance of this car is hidden, with the black front grilles doing a great job of hiding the cooling setup. The exhaust tailpipe is just as subtle looking as the standard item; it even has the ‘One’ badge on the tailgate! Amazingly for a drag car, the styling exercise continues under the bonnet, as 1320 have very cleverly designed the custom wiring loom to make things look as tidy as possible, and even cut and shaved parts of the bay to give it a smoother look.

Things stay just as classy and ‘un-drag’ like when it comes to the inside, as while the car has safety features such as the hardcore Kirkey bucket seats and custom rollcage, the interior is fully trimmed. Remember, this is a fully MOT’d road car, and 1320 wanted it to look like one.

There are plenty of trick additions that aren’t easy to spot at first glance, all in the name of performance. These include the Race Technology digital dash – they’ve even relocated the fuse box and ECU for easy access when doing quick tweaks between runs in the FWD Drag Series.

Although 1320 don’t want to strip the interior or add fibreglass body panels, they estimate, without any more tuning, it would be running 9sec quarters if they made it a hardcore stripped out drag car. But that’s not their aim; they want to go as quick as possible while keeping it as a true MINI. The current monster billet turbo is actually capable of over 700bhp with increased boost, and the engine certainly isn’t at its limit either, so once the new fuel system is installed, the guys plan to increase the boost to at least 35psi. In the fantastically capable hands of 1320, will this MINI monster get down in to the 9s on the strip and even give a £1.5 million Veyron Super Sport a run for its money? We’d be willing to put money on it!
