Accurate Power Measurement
REAL-TIME TUNING IN A CONTROLLED ENVIRONMENT
Checked consistently to ensure true BHP and torque outputs, Scooby Clinic's latest-grade rolling road is maintained in tip-top condition and operated by highly skilled technicians in the Dyno Shed. Safety of both car and personnel is paramount and closely monitored to ensure it is maintained at a high level. Unlike some facilities where the dyno is simply a tool for flashy numbers, we use our rolling road as a precision diagnostic and development platform – providing accurate, repeatable results that you can trust and compare session after session.
Our rolling road services cover everything from baseline power runs and before-and-after comparisons through to full custom mapping sessions and performance diagnostics. Whether you're verifying the output of a recent modification, troubleshooting a performance issue, or having a complete ECU remap developed, our dyno allows us to monitor critical engine parameters in real-time whilst simulating real-world load conditions. We can observe air-fuel ratios, ignition timing, boost pressure, exhaust gas temperatures, and knock detection all whilst the engine is under load – something that's simply impossible to do safely on the road. This controlled environment means we can push your car to its limits whilst keeping everything within safe operating parameters.

Whether you're chasing big numbers for bragging rights or simply want to understand how your car is performing, our rolling road facility provides the answers you need with accuracy and professionalism you can rely on.

Update: So been back to the clinic for a brake upgrade and while there they had a look round it for me and found a couple of bits needed doing to save me bigger costs in the future. All repaired to the highest of standards thanks for saving me again guys keep it up. Would recommend scooby clinic in an heartbeat I had a full engine build here and I'm very impressed with the quality of the build and the care they took with my pride and joy. Very very knowledgeable specially with Subaru's. kev put my mind at ease at every stage and the lads working there was also very helpful kept me updated from start to finish. Will be back 100%

Excellent customer service from the start, been a long project but come a long way as well, can't fault anything at all. Kev has been really helpful throughout, with comms and work done, Will be going back again in future that's for sure!! Cheers for all the help guys, appreciate it. 7 Year + Update: it's been over 7 years and I'm still with these guys, they've taken care of so many issues for me and I still won't go to anyone else for work even though visiting them is a 2.5 hour drive away. Their customer service is second to none and they treat me like fanily every time I come in. They've gone ABOVE AND BEYOND what any normal garage would put up with, so much so words genuinely can't describe how they've helped me through rock bottom times and not judged me or said a word about the state of my car, they were there for me and let me take my time sorting things out. I wouldn't recommend anyone else when it comes to who I go to work work on my scooby. My most heartfelt thanks to the whole team there, they work wonders and have a passion for subarus which I hope keeps shining as long as we can keep them running as I love them just as much. I'm sorry for putting you guys through what I have especially the apprentice that guys a freaking OG, he deserves a pay rise, but as well thank you for helping me keep my bucket of bolts going over the past near decade. You'll see me for as long as I can keep my Scoob going, thank you. Ps - don't tell anyone Dan makes a mean coffee or he'll kill me 👀😄

Ever since owning a Subaru I've always taken it staight to these guys if I need any work or simply some advice. After a recent accident, they repaired my car to a super high standard I couldn't have asked for more! The best subaru specialist in the UK

After recently purchasing a car I took it to scoobyclinic for an oil service and health check. The service was amazing and they really do have the right staff there. I asked a million questions and the staff was more than happy to offer advice. I only found out when I was there that they offer many services including engine and body work. I can not recommend them enough for your Subaru requirements.

Had them install a Syvecs Ecu and a fuel pressure regulator. I've had a fully rebuilt engine last year and I seemed to have a lot of hesitation around 3000rpm and mapped a few times didn't seem to fix my issue. Anyway, I decided to go for it and get Scoobyclinic to install a new ECU for me. It was my first time with them and I think they will be the garage I go to for all my future work/mods. Kev the owner kept me updated throughout the week and any new work that was carried out. They did come across a slight issue with my radiator where it was leaking and cracking and advised me that it would be best to replace. The car runs very nice so far. They guided me through everything that had been done and gave me some advice for future mods if I decided to take the car further (which I always will). They really looked after me and service was brilliant, worth the 90 minute drive for the service they provide.
