Hi All,

I'm hoping for a bit of advice / experience relating to the ACT Superflare Trumpets and Gasket and the full smooth induction hose kit. The loose change pot dictates that I'm going to have to do this in stages and before I commit I was wondering of others who have fitted these components, have you noticed any significant difference in driving / torque etc and then how easy it was to install. I've read about the difficulties in working the trumpets loose and cleaning out the old adhesive before refitting. Any tips would be really welcome.

My thought is to start with the trumpet conversion and then when funds allow in a month or two purchase the full induction kit.

Is it worth it ? Car is a 4.3

Many Thanks

Jeremy

I would be surprised if you would notice that much difference. If it still has the coiled wire set up on the air intake, I would give that a good check over to see if it is collapsed at all. On both my cars, it wasn't the best, so I changed to the smooth bore pipe set up, which can be fun to instal at the radiator end...

Other than that, provided all is working as well as it should do, spend the money on petrol would be my advice!

The trumpets, gasket and smooth bore elbow are the cheapest 10-15 bhp/lbs.ft that you will ever get from a healthy 4-4.6 litre RV8. The trouble is the slippery slope after that... wink

I fitted the superflare trumpets, thermal gasket, smoothbore induction kit and a V8D MC1 cam all at the same time. The car felt a lot quicker, also a lot smoother. Dyno checked after it was installed and it now makes a solid 240hp (good for a 400). I have an old dyno chart somewhere with before figures, but can't remember what they are off hand.

Well worthwhile upgrade in my opinion. The car drives really smoothly now, I'm really pleased with the results.

It's a bit of a pig to fit the induction hose near the radiator, but otherwise it's all pretty straight forward.







Lots of other bits have changed since this pic!

I got the old trumpets out by inserting a length of pipe in them and giving it a wiggle and they came out easily. This was a 4.6 with the standard Rover ones.

Yep, they come out easily with a wiggle.

Make sure you lay the new carbon trumpets out on the table first and see how they fit together. It's a bit of a jigsaw puzzle.

Don't do it... Just don't.....
Take a step back and ask yourself this one question.... Why do I want to undertake modifications that will increase my engines power output?
I firmly believe that many of the 'perceived' increases in performance or better 'driveability' are psychologically induced by the fact that achieving them has lightened your wallet. By quite a bit.

Spending money on the mods you are talking about will probably make the car feel better/faster (in your mind) but in the real world it'll probably make feck all difference... I spent the best part of £8K when I had my engine rebuilt (it needed rebuilding), and it worked out at about a thousand pounds per 10BHP gained... fecking madness... (from a financial perspective) but it is awesome to drive...

The only real way to cost effectively turn your TVR into a proper quick (by todays standards) sports car is to go FI...

If you don't you will forever face the humiliation of being left in the dust of chipped up BMW's and Golf R's......

And that's not a good place to be wink

Meh. If you want to start a pissing contest with modern FI cars, buy a modern FI car. At least that won't chuck you into a hedge a**e first whenever it comes on boost. biggrin

Some people just want to get the best from what they have without effing-up the car's character. There's a HUGE potential for refinement with the RV8 TVRs and very little of it has to do with chasing outright numbers.

It's the reason people pay hundreds of thousands of pounds for a Singer Porsche or Eagle E-type. In simpleton performance terms, they too might be eaten by chipped BMWs and Golf Rs. Do the owners care...? Of course not. One is a perfectly honed, very analogue sports car custom built for its owner giving the driver a fully flavoured blend of sensations, the others are digital boxes on wheels that happen to go fast.

£100 per BHP sounds about right for naturally aspirated tuning, but then you have a brand new, perfectly balanced & smooth running engine instead of the old mill that was there before so another way to think about it is that you've restored a major part of the car and got the extra performance thrown in for pretty much free.

Also, £100 for one bhp that only needs to pull a tonne (give or take) is only half as bad as £100 for one bhp that is burdened with a 2 tonne kerb weight. wink

It would be nice to see some figures on paper for these modifications, the trumpets and hoses cant seriously gain anything more than a couple of HP surely?

I'm about to embark on a few modifications and am planning to get a few power runs on a rolling road before, during and after so will see where my money went yikes

My car is a 450 and has a worn camshaft and as such I will be replacing this towards the end of May, adding stage 3 heads, replacing the trumpets and also including a 72mm plenum as well. I'm sure a few other things will be added to the mix during the process as breathing appears to be the key issue with getting a few more BHP from these engines. Towards the end of the year I am going to get Dom to fit one of his MBE systems and then leave all alone for many years hehe

I'll get a base run, a run after the camshaft is done and one when the MBE is set up and see what my money bought me.

not sure what the spec is for your planned heads but I would be fitting these bad boys if it was my money and doing all that work: http://www.v8developments.co.uk/products/heads/sta...

Peter (Phazed) saw noticeable benefits from these over stage 3.

ACT had several on their website, can't find them now. It is more than just 'a couple' of BHP, though, anything between 8-15 bhp has been observed on otherwise standard engines. Particularly the trumpets are very effective, you just have to look at their shape to see why they cannot be compared to putting bellmouths on the OE pieces of tube...

May I ask what the BHP before figure was? Also, what the torque before and after figures are too? If you have them smile

I think you've missed 'Chillis' point by some margin, he speaks sense and his meaning is lost on the humour. So, I have a FI car, didn't go through a hedge backwards first time on boost or the many other times even on a trip to Italy and back [did do 'before it was FI though] wink Have you been in a FI TVR? Have you driven a FI TVR? I ask because most who slag 'em off haven't been near one and merely quote what a mate says or something read from another idiot.
Back on topic, don't expect a noticeable increase but it all helps in the bigger picture and it's a start, makes sense and Tim makes some quality products of which I have most of. I'm all for doing what you can, when you can and good luck to you.
