Is that still runnings stock gearbox and clutch?

Nice blue twin, exepting the turbine ...

Lovely colour. Is that Pearl Blue?

Some nice feedback received from another happy customer, thank you Ron. Check back later for more photos and videos of the work carried out on this very powerful turbocharged TVR Chimaera 450.

"Great job, the car drove very well on the drive home. Very smooth and great power delivery, excellent throttle response. A first class professional job, thanks to you both.
Kind regards. Ron B."

That’s a nice car

Many thanks for your review Rob and good luck with your future racing events.

"I took my 1979 Morgan Plus 8 down to the boys at Lloyd Developments having found them on the internet. V8’s is what they do!
My car is a 3.9V8 with a 224 Kent cam, flowed heads and SU carbs which I use in the Classic Marques and Morgan Car Club Sprint and Hillclimb Championships.
I had an unresolved mid-range rough running issue which a number of “experts” had failed to resolve inspite of rolling roads and other failed diagnostics. The Dyna Hub Pack Dyno interested me as it presented a different approach to the problem. After just an hour and a half the issue was understood, addressed and resolved.
I would really recommend this team, a warm welcome, friendly and knowledgeable staff, and good coffee!! I won’t hesitate to go back in the future.
Many thanks

I can agree with the above,Lloyds built a big valve 4.8ltr engine with canams injection for my morgan +8 , the performance is mind blowing.
