My understanding is that any changes to plenum/throttle body (if executed correctly) can yield big improvements in throttle response.

In my humble opinion too many people on here seem overly fixated with horse power numbers.

I totally understand why people do this, the TVR crowd can easily put a ruler on their members, take a picture of it, then post it on Penis Heads (in the format of a rolling road graph).

But what gets completely forgotten in this arms race for bigger & bigger numbers is what I believe to be the most important element of all.

HOW THE CAR FEELS TO DRIVE!

To this end a lighter flywheel or an ACT twin plenum may have little or no impact on the slang waving graph poster's horse power figure.

But a TVR Chimaera with those two mods is certain to go from feeling dull & average, to feeling like a lithe and alive sports car.

You can't post the results of how your car feels to drive on Penis Heads, but you sure can feel it yourself every time you go for a blast!

Ask the question, "Whats more important you you?"

Emperor's new clothes syndrome is more common....

Trying to belittle folks that try and measure their improvements with some kind of sanity seems well, rather absurd really????

You can get a load of trouble with the twin plenum now- they are getting old, and the seals / bearings around the throtle spindle wear out and let in air, so you cant get a stable idle.

I might use two other TBs then, new ones, have anything in mind that would suit? Or just anything between 60-70mm?

I did try a twin throttle bodied adapted plenum.

When tried on the rolling road it gave a worse figure then standard.

We then found that the engine build on my 4.6 that had just been done was absolute st, (suddenly adopts angry tone as the memories flood back!)so the test wasn't really relevant.

Simon, (Sardonicus) now has the plenum and may well try it one day.............

FWIW the ACT twin has 2 x 55 mm throttles, and that is good up to and including the mid-300 bhp range...

I tried the Act twin and was very happy with it. Not much on bhp but great throttle response, as Dave says it's this that gives a car a nice 'feel'. Only for the supercharger it would have stayed on.

Forgot to say mine is absolutely massive, and it will get even bigger with a supercharger!!

Thank god the two above (& ChilliPenis) all understand not to take this TVR ownership too seriously.

Belittling sanity checks and Emperor's new clothes aside, it's just a clucking hobby for clucks sake!

Does having a huge encyclopedic knowledge of an ancient long since discontinued aluminum V8 come with a sense of humor bypass or something?

You just wait till I slap my Supercharged LPG powered wang on the table, then you'll all find out what a huge cock really is byebye

As per above.

Oh and 'don't make important what you can measure, try to measure what's important'.

The moment you got left standing by cars with half the power/weight, you might want to concede that just maybe you've been developing your car into the wrong direction? After all, on a dispassionate SWOT analysis of our cars I cannot imagine 'lack of power' comes up as the main Achilles' Heel, anyway...
