AlfaWorks built a bonkers 410bhp Alfa Romeo 4C

Here's how AlfaWorks turned a pretty Italian sportscar into a true tarmac-terrorist.

AlfaWorks have been on the 4C tuning scene for a while now. Back in 2018, I was lucky enough to get a passenger ride in the red 4C you see in the photo. At the time, it was running around 350bhp which, to me, felt like the speed of sound. I'd been passenger in quicker cars at that point but the lightweight, raw and hardcore nature of the 4C gave it a crazy sense of speed.

350-ish bhp AlfaWorks 4C launch with a giddy teenager's reaction...

I managed to dig out the short video I took and, as you can see from the reaction of my 16-year-old self, it blew me away. We stopped in the middle of a national speed-limit single carriageway, holding up cars behind, before leaving them for dust with a quick launch control. What an experience.

Since then, Jamie Porter and his team of specialists have gone to town even more on the 4C, increasing power to 410bhp and achieving 600Nm of torque. The 240bhp the car has as standard gets a shift on - so imagine 410bhp in a car that weighs less than 1,000kg!

This has been achieved by stroking the engine, from 1742cc to 1995cc. New pistons, a modified crank, different thrust bearings and con rods allow the engine to achieve bigger power, reliably. The key to optimising the 4C's performance appears to be maximising airflow from when it enters the engine, to the point it's shot out the tailpipes. The cylinder head is gas-flowed, rather than used to create an emission-friendly swirl, to increase flow-rate and get as much air into the turbocharger as quickly as possible.

AlfaWorks replaced the standard turbo with a Borg Warner twin-scroll unit, which leads into a free-flowing, heat-shielded, tubular exhaust manifold. To connect the engine components, you'll find an abundance of silicon hosing and heat protection to keep engine-temps under control.

Combine all of this with an SCS Delta Motorsport ECU and Bob's your uncle.

The car maintains Alfa's DNA driving modes, with full power being available in 'Dynamic' and 'Race' modes, whilst 'Natural' and 'All-weather' modes 'only' get a restrained 300bhp.

Adjustments have been made to the suspension to perfect the 4C's already superb handling. The setup also combats the 'tram-lining' issue as a result of poor road surfaces. Bigger wheels are also available, much wider than standard, with 8.5x18 in the front and 9.5x19 in the back. Pilot Sport Cup 2 tyres from Michelin provide a razor-sharp turn-in and great high speed stability, allowing the 4C to be pushed to its limit.

The owner of the Auto Italia tested white Alfa 4C 410 chose to keep standard suspension which shows that Alfa Works are willing to tailor the build to your personal preferences.

So, how much does it cost?

For a 410bhp 2.0-litre 4C, the full conversion will set you back £23,148 or just over 27,000 Euros. That's an additional two-thirds of the price of a used 4C, on top of the car itself. But for a month-long meticulously detailed build that, at the end, gives you a supercar slaying 4C... it might just be worth it.
