Enginetuning
Ignition, fuelling and flow optimisation for maximum power without sacrificing reliability.
Ahlqvist Racing
and Tuning
We work in racing – tuning and dyno testing of small engines, with karting as our speciality. We are not only chasing power; we know the tenths are what decide a race. On top of that, we develop our own software for racing and rental karting.
OUR FLAGSHIP APP
A.R.T Racing Timing
Live timing for rental karting. Data is read straight from a Mylaps decoder and pushed to the browser in real time, so drivers, spectators and organisers all follow the race on the same screen.
- Live lap times, positions and gaps
- Reads directly from a Mylaps decoder
- Big-screen and mobile views for the whole venue
- Built for rental kart centres and race organisers

Dyno Testing
Power measured before and after the work. You get curves, numbers and a report – no guesswork.
Rebuilds & Blueprinting
Teardown, measuring, balancing and assembly to exact tolerances – porting only in KZ. We also replace conrods and bearings on most engines.
Race Support
Race preparation, tuning between heats and troubleshooting when it really counts.
Rental Karting
Service, engines and tuning for rental kart operations – equal karts and consistent lap times.
3D Printing & Tools
We design, print and sell tools for karting – dial gauge stands, jigs, measuring aids and custom parts. Printed on our Anycubic Kobra S1 Ace 2. Have an idea? We build it.
Precision Electronics
Repair and service of racing electronics – AIM MyChron dashes, MYLAPS transponders, looms, sensors and connectors. Board-level work, not just replacement.
Software & Hardware
In-house systems for timing, measurement and data analysis in rental karting and racing.
Dyno Testing With Proof
Every engine is measured before and after. You see exactly what the tuning delivered – power, torque and how the curve behaves across the whole rev range.
- Power and torque curves
- Before and after runs on the same dyno
- Printed measurement report
- Flow and ignition troubleshooting
The Workshop
Shots from the bench – dyno runs, balancing, crankshaft truing and measuring down to hundredths of a millimetre. We only port in KZ, where the rules allow it.

Winning Engines in Karting
We have a proven record of winning engines – everything from Raket 95 Micro to KZ2, including Rotax Max and IAME X30. KZ is the only class where porting and machining are allowed; in Raket, squish and ignition timing may be adjusted, and on the X30 we hone the cylinder and match the pistons. We can also replace conrods and bearings on most engines. Every engine is fully measured – precision, balance, tolerances and dyno testing, all documented with real data.
CLASS
Raket 95 Micro
Fully rulebook-legal build – precision, balance and verification on the dyno. Squish and ignition timing may be adjusted.
CLASS
Raket 95 Mini
Tight control of tolerances and balance, verified with before and after runs. Squish and ignition timing optimised within the rules.
CLASS
Raket 120
Clean, carefully assembled engines with a balanced crank and a dyno-tested curve – squish and ignition set for the class.
CLASS
OK-Junior
Measuring, balancing and dyno running – nothing outside the rulebook.
CLASS
Rotax Max
Every dimension measured and matched, balanced and dyno tested – the build stays within the rules.
CLASS
IAME X30
We hone the cylinder and match the piston for the right clearance, followed by verification and dyno testing.
CLASS
KZ2
The only class where porting is allowed: porting, machining and dyno testing.
Software, Hardware & Data
We build our own software and hardware for rental karting and racing, and analyse data from both track and dyno. Lap times, power curves, weather data and logs turn into concrete decisions on setup and engine choice.
Products
Two in-house apps for kart and racing people. Try them live – get in touch for a licence, customisation or purchase.
LIVE TIMING
