ACT Performance Products and Carbon Design Technology have joined forces to produce a range of carbon fibre induction products for TVRs.
New induction products for TVRs
ACT makes Speed Six carbon fibre airbox
Tim Lamont (ACT) and Allan Thompson (CDT) have announced the release of the first joint product, a replacement air-box system for the Speed Six engine.
Features
- Full Autoclaved Carbon Fibre construction for Strength and Durability
- Optional individual internal trumpets to maximise torque
- High quality stainless steel catches
- Supplied with free-flowing Pipercross air filter
- Fitment suitable for TVR Tuscan, Tamora, T350 & Sagaris
The project has been helped along by TVR Tuscan owner Richard Wallis (BigGriff) who has been enthusiastic and kindly let us use his air-box and trial fit in his own car to help develop the system.
Prices
- Standard Airbox, icluding new filter: £755
- Performance Airbox, includes internal trumpets & filter: £875
Prices exclude UK delivery & VAT.

Theres a german guy who made something very similar and completed it with a cold air induction kit. If i remember correctly he claimed somewhere between a 15 and 20 HP gain for his system. It was advertised in the german TVRCC-magazine. He also said that the original TVR-airbox wasn`t really airtight.
You can contact him trough tvr-deutschland.com even if this particular product is not yet on that homepage.

Not cosmetic. It actually does what the TVR one does not.... filter the air.
The one we took of was not even square so air was getting in all round (common apparently). In addition the standard ones are very thin and fracture on the stub pipes and the casing.
Find out how much TVR will charge for a 'standard' one before you decide that it is poor value.

Its a straightforward fit.
The best way to get the improvement is to have a remap at somewhere like Austec like you would with any modification. You will get the maximum out of it then, but even without the engine will breath more easily and with the novelty of filtered air!!
Once mine is remapped I will post the results and we can get an idea of the improvement level.

Tim at ACT is also looking to add a cold air inlet pipe. Once that is available I will fit that as the TVR one is not nice!
Hmm. Personally, not sure about any real-world gains with that. The existing set up is unusual but may be just as effective, as it most certainly effectively picks up cold air from beneath the car.
The std set-up doesn't have any 'ram air' effect, but any research will show that actual gains from ram-air alone below 200mph are tiny, any real gains are just from avoiding hot underbonnet air, which it already does.
A cold air intake at the front of the box will favour the front cylinders over the rear as well I think, unless restrictions are added. Not good.
Guess it needs full scientific testing to prove out, but I'm sceptical that it's a step too far I'm afraid.
(this relates to T350 pickup from chassis level - not sure Tuscans are same)

Would look great for Tamora, T350 , Speed 6 Cerb & Sagaris you can see it, but Tuscans no .
One good point it wont melt so thats always a good thing
As for ram air i have had this for 6 years and i can say responce at over 4000rpm or over 100mph is stagering concidering standard unit acts as a vacuum sucking air out as engine is trying to draw air up from ground level (ie chimney up side down)
People can be sceptible ,and to be honest only small gains in BHP are seen but- when you hit the loud peddle out of any long or short corner say on track its amazing
