How To Choose

Four Decisions, In The Order They Matter

One: how many driven wheels. If you tune xDrive, Quattro, 4Matic or anything with an active centre differential, you need a mechanically linked 4WD rig — a single-axle dyno cannot measure those cars safely. If your work is front and rear-wheel drive, a 2WD rig is a third of the price and upgrades to 4WD later.

Two: inertial or braked. Inertial measures acceleration against a known mass — accurate, simple, and all you need for power runs and customer printouts. Eddy-current brakes let you hold a fixed rpm and throttle opening for part-throttle mapping, steady-state work and transient testing. Brakes can be added later on the inertial models.

Three: where it goes. Above-ground installs faster and can be moved; in-ground gives a flat floor and easier loading but needs a pit. Both are available on every car and van model, and the 2WD rig is also offered as a mobile unit.

Four: what you are putting on it. Car and van models take 3,000 kg per axle; the VT-2/Truck takes 15,000 kg with up to 6600 Nm of braking torque; the VT-1 is the bike rig, with a quad version available; and the VT-PTO measures straight off a tractor power take-off.

Before You Spend

You Might Not Need To Buy One

A rolling road is a serious purchase and the honest starting point is whether you need to own one at all. If you are putting a handful of cars a month on it, hiring dyno time is cheaper than owning, housing and maintaining a rig — we run dyno power runs on ours at Birchwood for exactly that reason. Buying starts to make sense when the dyno is how you earn, not something you use occasionally.

When it does make sense, the mistake we see most is buying for today. Every V-Tech 2WD rig upgrades to braked and to 4WD, so the money is not written off when the work changes. The second mistake is buying more brakes than the work needs — an inertial rig measures perfectly well, and brakes are for mapping under load, not for bigger numbers.

We are a working tuning shop before we are a supplier, which is why we will talk you out of the wrong model. See how we use ours for live dyno calibration, or the full technical detail on V-Tech Dyno UK.

Buying Questions

Buying A Rolling Road, FAQs

How much does a rolling road cost?

The range starts at £14,500 ex VAT for the inertial single-axle VT-2 and runs to £77,000 for the fully braked 4WD-linked VT-4/B4, with the VT-2/Truck from £94,000. Motorcycle and PTO models are quoted per enquiry. Those are prices for the rig — delivery, installation, commissioning, software setup and training are quoted per site.

Can I hire dyno time instead of buying one?

Yes, and for a lot of people that is the right answer. We run dyno power runs on our own V-Tech 4WD-linked rolling road at Birchwood, Warrington — see dyno power runs to book time rather than buy a machine.

What is the difference between a dyno and a rolling road?

In UK usage they are the same thing. “Rolling road” is the workshop term for a chassis dynamometer — a set of rollers the car drives while power and torque are measured at the wheels. An engine dyno, by contrast, measures an engine on a stand with the gearbox and driveline removed.

How accurate are they?

Relative accuracy is better than 0.1%, from 3,000 real measurement points per second using V-Tech’s own technology. Correction to DIN, EWG, ISO or SAE standards is built into the software along with an ambient pressure and temperature weather station.

How much power can they measure?

Up to 2000 HP with the appropriate configuration. V-max is 300 km/h on the car, van and motorcycle models and 200 km/h on the truck dyno.

What comes with it?

DynaVTECH software, built on V-Tech’s patented TrueForce II torque-measurement technology: power and torque in inertial or braked modes, constant-rpm and steady-state runs, live logging of boost, AFR and temperatures overlaid on the same graph (plus OBD/CAN data with the optional interface), comparison of up to four runs, correction standards with ambient pressure and temperature recording, and branded printouts with your own logo stored in a database.

Who installs and supports it?

We do. DC Remapping UK handles spec, pricing, delivery, installation, commissioning, software setup and training UK-wide, with a standard 1-year warranty, extendable by a further year after a V-Tech service inspection, and free software updates while under warranty.

Why buy from a tuning shop rather than a distributor?

Because we use the same equipment. Our own V-Tech 4WD-linked dyno writes customer maps at Birchwood every week, so when we tell you whether you need brakes or whether the inertial rig will do, that is from running one commercially rather than reading a brochure.
