TVR Tuning Tips and Modifications
Maximise your TVRs driving pleasure
TVR made a wide range of real drivers car – shunning much of the accepted gadgets like power steering and Aircon. Read our TVR car tuning tips and advice and join our TVR owners club. We have a wide range of tuning articles covering all models of TVR from the classic Tasmin to the modern Tuscan and speed 6. Sadly TVR are no more and it is probably for this reason that TVR are looking to modifications and car tuning to upgrade their cars. Following our tuning tips you will avoid many of the common mistakes and actually achieve the car setup you desire without spoiling that essential TVR ingredient. Please join the forum for model specific questions and answers and to meet other owners and see what modifications they have done.
TorqueCars started providing TVR performance part tips, car track day setup and car engine tuning advice and reviews back in 2003 and have grown from strength to strength with a fast growing membership of all types of cars including many, TVR owners. We are currently one of the fastest growing car tuning clubs around and certainly one of the friendliest. In 2007 we also organised our first full car show.
Our TVR comprehensive modification articles on tuning and styling are kept upto date so for the very latest TVR performance part,track day setup and engine tuning advice, tips and pointers please check back regularly. We strongly recommend that you join our TVR forums and swap performance part ideas with like minded TVR owners in the performance part forums.
If you have a TVR project underway we would love to hear about it, the Gallery section in the forum contains some interesting projects. Scroll down the page to see our latest tuning articles for your TVR.

TorqueCars will review sports exhausts and exhuast design as they are very popular modifications, but sadly many mistakes are made.
The job of the exhaust is to break up the sound pulse from the engine, muffling the sound and allowing the exhaust gases to escape efficiently.
Suspension settings, lowering and stiffening
On the track your priority is fast cornering and suspension plays a large part in this. Track conditions are quite forgiving and you can make some compromises like using hard suspension and lowering the car for optimum aerodynamics and a low centre of gravity.
This works well because tracks are fairly flat and you do not have a carrier bag full of eggs in the car from your return trip to the supermarket.
Principles of porting an engine and big valve conversions
The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.
This allows for scope in the manufacturing process to allow for mismatched alignment.
Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
Boost controllers and remaps
Boost controllers
The turbo is driven by the exhaust gases and the faster the exhaust flows the quicker the turbo spins and more air gets forced in to the engine.
If too much air is forced into the engine then it will run lean. This causes an intermittent loss of power and you also risk putting too much pressure on the engine with a surge of power.

Hybrid turbos
As a rule the turbo engines are stronger than the NASP equivalents and are able to handle substantial power gains.
The key thing in a turbo engine is the flow rate that can be generated and this depends largely on the internal profiles of the impellers inside the turbo.
