DYNO CELL - Rolling road
The Atspeed Essex workshop facility is host to a spacious 32x14ft sound proof dyno cell, featuring an external spectating room for safe, comfortable viewing.
*FREE WiFi internet access*The dyno cell is very well lit, and clinically clean.
The dyno cell has numerous cooling and extraction fans, and is capable of changing the air in the dyno bay 4 times a minute, resulting in a more accurate, safer test environment for you and your car. The main cooling fan is capable of keeping a well designed cooling system on a 600+ BHP car cool for many hours of continuous dyno testing. All temperatures are constantly monitored at all times.
OUR DYNOInside the Dyno Cell lies our 1000BHP Clayton 2WD chassis dynomometer, capable of inertia (2000bhp) and FULL LOAD testing upto 1000BHP, whilst handling speeds of up to 200mph. This rolling road has one of the highest capacities known in the UK, making us popular with some of the UKs leading tuners.
The Clayton Dyno is embedded into the workshop floor, its low profile allows even the lowest of todays modern race cars to be tested without the common ride height issues.
DYNO SOFTWAREAtspeed use Land & Seas "DynoMax Pro 2000" software. This allows pretty much limitless channels to be monitored, including: AFR, Boost, Torque, BHP, Exhaust Gas Temperatures and many MANY more! Dyno print outs are available, and graphs can be overlaid for comparison. The dyno max software also has a "playback" facility, meaning there can be more time spent analyzing, and less time spent wasting fuel or wearing the engine out. The playback can be viewed in realtime speed, and slowed right down to fractions of a second, making it ideal for fault finding or accurate mapping. These are just a few of Dyno-Max Pro 2000's features, the possibilities with this software are almost endless.
The Atspeed Dyno Cell is also host to Land & Seas weather station, which automatically corrects readings to industry recognised standards. Wether it be summer or winter, result consistancy can be maintained.

BASIC TESTING PROCEDUREMany people are put off by the horror stories of the past regarding rolling roads and the stress and strain on engines as the dyno operator tried ever further to make the big dial on the wall read higher. With the latest breed of computer technology and rolling roads, this is all a thing of the past.
A typical dyno power run now lasts around 8-10 seconds at full throttle. During that short time we have live recorded all the required data we need, air fuel ratio, bhp, torque, rpm, manifold pressures, temperatures etc.
Firstly the car is reversed into the Atspeed workshop, here a quick safety check of the car is carried out, such as wheel/tyre condition, engine fluid leaks/levels, driveshaft CV boots, condition of coolant hoses etc. All basic stuff, but the vehicle must meet these simple safety checks before any dyno testing can be carried out.
A stainless steel lambda bung can be welded into the exhaust system at the collector, to allow the wideband lambda probe to monitor the exhaust gases, two probes are fitted for V engines (one for each bank), this is recommended for accurate Air Fuel Ratio (AFR) readings when setting up light throttle openings where slow exhaust gas speed is achieved. So vital for mapping of carburettor tuning. However for a simple power run, a lambda probe can be inserted up the tailpipe for accurate full throttle AFR readings.
The car is then placed onto the rolling road, and securely strapped down in place. Vehicle information is then entered into the Dynomax Pro software, such as engine size, tyre size and any specific vehicle information. Other additional sensors for boost pressures, oil/water/air temperatures, exhaust gas temperatures (EGT) may also be added. The vehicle is then driven slowly to synchronise engine RPM with roller speed, for accurate RPM readings. Testing is usually carried out in 3rd/4th gear. We are now ready for testing.
A baseline run is then recorded usually from 2500-3000rpm up to maximum power. Of course carefully monitoring engine conditions and behaviour. Automatically the dyno slows down to a stop, and the recordings are analysed and displayed as a graph.
Armed with this information we can repeat tests over and over again to within+/- 0.1% accuracy, graphs can be overlaid and prove any gains we have made. There is no guesswork with this technology.
