Challenge
The workshop needed a way to show its services and measured cars, and to let a visitor see straight away how much their car could gain.

For SJ Performance, a chip-tuning and dyno workshop in Ljubljana, we built a website that presents the services, measured projects and the path from a message to a dyno run.
Visitors land on a hero with a car and a call to enquire. Services follow, from Stage 1–4 and the Mainline ProHub dyno to EGR, E85 and hardware, featured projects with power before and after, the process and contact on Leskoškova cesta.
The site also includes a power calculator. A visitor picks the brand, model, year and engine and sees how much power and torque the car would roughly gain at each stage, along with a price.
The site runs on Next.js with Tailwind, in Slovenian and English.
Solution
A Next.js site with services, projects, a dyno section and a power calculator by brand, model and engine.
Results
A calculator where a visitor sees the rough power and torque gain for their car, plus an enquiry for an appointment.
