Rolling Road & Dyno Testing in London & Hertfordshire

Rolling road and dyno testing in London and Hertfordshire

Perfect Touch is home to a 4WD Dastek rolling road, one of the first four-wheel-drive dyno installations in the UK when we commissioned it back in 2006. A rolling road, or dynamometer, lets us run your car safely under load indoors and measure exactly what it is doing, so we can put real, accurate numbers to its performance and pinpoint faults that only show up on the move.

We use it for accurate BHP and torque measurement, fault diagnosis under load and setting up mechanical work, on everything from an everyday hatchback to a performance car of over 1000 bhp. It is a measurement and diagnostic tool, not a remapping service.

What we use the rolling road for

Wheel & flywheel BHP and torque measurement

Diagnosing faults under load

Replicating intermittent & on-road faults

Verifying mechanical & forced-induction work

Motorsport & track-day setup

Before-and-after performance checks

FWD, RWD & 4WD support up to 1500 bhp

Full colour print-out of every run

The ultimate diagnostic tool

Our dyno cell was designed and built by Dastek UK as a development of the original South African design. It simulates real-road driving with maximum safety for both car and operator, with a 20hp cooling fan up front keeping temperatures down. That makes it the ideal way to investigate problems that are impossible to catch on the road, using data-logging and measurement equipment kept inside the cell.

A rolling road session pairs naturally with our car diagnostics and servicing, and it is a core part of our race car preparation. It is especially popular with owners of performance marques such as the Subaru Impreza, Nissan Skyline and GT-R.

Rolling road FAQs

A rolling road, or dynamometer, is a set of rollers that the car’s driven wheels sit on, letting us run it safely under load indoors. It measures power and torque accurately and lets us diagnose faults that only appear when the car is working hard.
It depends on what you need, from a single set of power runs to a longer diagnostic session. Get in touch and we will give you a clear price before you book.
Yes. Our 4WD Dastek dyno produces accurately calculated wheel BHP, flywheel BHP and torque figures, with a full colour print-out of every run for your records.
We use the rolling road for accurate measurement, fault diagnosis and setting up mechanical work. We do not offer ECU remapping.
Yes. Our dyno supports front, rear and four-wheel-drive cars and handles everything from small hatchbacks to performance cars of over 1000 bhp.
Our workshop is on Sewardstone Road, serving drivers across London, Hertfordshire and Essex.
