WANTED - Chim ACT induction hose parts
Discussion
I'm looking to replace my tatty TVR tumble drier induction hose with the ACT upgrades, and achieve not only less tat, but possibly an unknown quantity of horsepower (LOL), mainly less tat.
I already have acquired the main length of hose, which has the joiner with it, but not the elbows (or the heat sleeve) - as highlighted in the photo.
I'm all lined up to buy directly from ACT, but thought I'd ask if anyone has one or both of these items that they no longer want or need, and I'd be happy to give you a fair price...

I have all that including a full length heat shield direct from ACT a good few years ago.
Trouble is it’s excellent and I’d never part with it,,, sorry
I happen to feel it’s a very good upgrade and worth every penny although I wasn’t sure at the time but all these years later still think it adds flow and just works much better.
I can’t see it ever failing either.

I've recently fitted the elbow between the AFM and Plenum and it seems to be working well.
I did notice that the first time I went out for a drive after fitting it, after a few minutes the engine started revving to 2000rpm in both second and third gear, even though I wasn't really pressing the accelerator, and then after about 20 seconds of this it returned to normal. I have been wondering if the ECU noticed the change to the airflow so was 're-learning' - I'd be interested to hear if you have anything similar happening after the install.
I didn't change the lower hoses as I've heard they are a little bit more fiddly but that may be something I look at in the future. I did recently replace the air filter and will just do an annual clean and re-oil on that going forward.

No worries, it was part of the ACT Induction kit but removed due to Powers MBE being fitted.
Hello, finally I have concluded my smooth bore purchasing journey.Long story short, thank you very much for the offer, but I no longer need your elbow. But I bet you can sell it readily should you wish.
It’s almost funny to look at the tumble dryer hose on the car compared to that elbow.
The silicone elbow from someone else turned out not to be ACT, nor suited to our cars by virtue of being a constant inner diameter that fits neither end of the system, so we agreed a return.
In the midst of that ACT made it very easy and sold me the parts I needed.
Next stop, fit it all.
I’m planning to fashion a bracket to support the filter higher up than it currently sits (on the bottom of the mouth), so will report back on my venture.
Again, thank you.
All fitted.
A couple of things that I discovered through the task:
ACT didn't provide any instructions or notes for what to do, even though it is simple.
I had to cut a reasonable amount off the plenum elbow to accommodate the AFM. I can only assume the supplied size allows people to remove the AFM with different ECU systems.
The neat detail is that the joiner between the longer length and the nose length makes the join at the bulkhead, so you're not trying to feed anything through the fibreglass.
The other detail is that the nose piece holds the air filter a lot higher and further forward than the original set up. I had to fashion a small bracket to attach to the upper part of the nose (and drill through to bolt it in place). No big deal, just did some measurements and bent a length of aluminium flat bar with big pliers.
Overall, I think the car has gained many BHP, and I need to cling on to the steering wheel with the searing acceleration.
Or is that all in my head?
Nice to be rid of the scratty tumble drier hoses anyway.

I must admit I was listening intently today, and I thought it was a bit louder somehow, but I’ve still got the AFM.
I think I do a lot of convincing myself at times
The AFM is only a slight restriction in reality. I think I do a lot of convincing myself at times
I’m not sure how much extra power is really achieved with the ACT full induction pipework but it definitely sounds faster
and there’s no question it flows better from filter through the wing and mines always felt more instant when the throttle is applied like the air is pushing up against the throttle butterfly more forcefully. The RV8 biggest restriction has always been the heads port and valve sizes which chokes off power so anything that reduces restriction getting air into the engine has to be a good thing and it could well add 5 hp or more for all we know.
Similarly de Catted the cars are slightly faster and you definitely feel the difference and some say that alone adds Upto 10 Hp so helping the inlet air speed might well do a similar thing.
Mostly in my cars case I think it helps low down and mid range power with less throttle applied.
The combination of the air pipe, no AFM and after market Ecu that can be programmed to offer more advance timing accurately is definitely faster at lower revs than without it but ultimate hp at higher revs is not changed much unless bigger valves and ports were to be used.
Regarding the extra timing advance one very obvious changes I felt after a new Ecu is how I can manoeuvre the car around on the drive without using the throttle at all. More torque for the same amount of fuel used equals more power.
