**2JZ RX8 Drift Car**

One of the builds we completed last year on our dyno for full power mapping running the full LINK ECU setup.

Got to 620bhp at the wheels before we ran into a fuel supply issue and the Wastegate being flat out too..

Soon to be out on track after the owner Declan makes the necessary changes needed so I can get the full potential out of his setup.

Look forward to seeing it in action 💥

Sorry for the sound quality, our camera microphone couldn’t handle the noise 😅👍🏼

Ginetta G40R Dyno Session

We had the pleasure of meeting Ian who brought his Ginetta in for a power run and afr check on our dyno. We found it was running very rich and slightly down on power and torque.

After discussing what the options were, it was decided we spend some time on the dyno fine tuning the fuelling which resulted in a small increase in power and torque and much better drivability which is what the main goal was.

Hopefully some better results on track for Ian 😀👍🏼

*******We’re back!*******

Hello again to all our customers, friends and followers.

So after 10 months of no updates I thought I should really update our social media, since we’ve had lots of people asking if we are still trading…

So first of all the answer to that question is YES we are still trading. 😀
We stopped briefly while moving workshops.

We are currently operating temporarily from a small workshop in Willowholme industrial estate, this was kindly offered to us at very short notice and allowed us to stay open as a business. So a big thankyou to Briony Fawcett and Geoff Parsons for the help with the temporary premises.

Another question has been about the services we offer..

We are still offering all the same services just at a different location and due the size of our workshop we are a little restricted but will try our upmost to accommodate you.

This includes:
Servicing & Diagnostics ☑️
Air Conditioning Service☑️
Engine Rebuilds☑️
Engine Machine Shop☑️
Remapping☑️
Dyno & Custom ECU Calibration☑️
Custom Wiring Solutions☑️
Custom Stainless Exhausts ☑️
Motorsport Fabrication & Preparation☑️
Restoration Work☑️
Vehicle Transport & Recovery☑️
Race & Trackday Support☑️
Trailer Hire☑️
Specialists in JDM, Performance & Supercar☑️

We’ve had a very busy year so far, working on some really nice projects, meeting new people and getting out to various tracks doing transport and support work at Silverstone, Croft and Spa-Francorchamps!

We’ve also got a new employee, Mrs Angela Underwood (aka the wife) is now helping out in the office, taking bookings, answering the phone and generally organising everything. Which has took a massive load off, so we are getting slowly caught up with outstanding jobs.

We have also started another side to the company called Underwoods Plant and Trailer, this is for our Plant and Trailer Hire customers which has been working away in the background for the last year.
We’ve got various machines and a few trailers that get hired out daily. All clean, tidy, professional and available at short notice, so please bare us in mind for any trailer or machine hire and if you could give that page a like and a share that would be very appreciated!

I can’t thank our customers enough for trusting us with their vehicles and it’s a pleasure to work on them. (Most of the time).
You keep our business going and we Thankyou for supporting us! Running a small businesses is harder than ever so every little helps!

A few photos from throughout the year so far..

Thanks
Scott Underwood
