Nice! I thought they sounded interesting. I am hoping to run mine for another year or so before I upgrade so hopefully they will have a bit more 'good' history by then.
Keep us posted!
Will do Nafem. I'm going for the Fury as it has a potential upgrade route that may extract more if I am stupid enough to try it.Keep us posted!

I'm doing mine bit by bit, as bits wear / break / fail.
Larger rear tyres (255), Nitrons / ohlins, Brake disc upgrade to Tuscan S spec etc.
Ultimately (if and when) it goes pop, 4litre Red rose engine.
Not spending the pennies till it's need though.
Very sensible approach! I am dithering over Nitrons V ohlins at the moment and need to research more hence the post to learn from wiser people.Larger rear tyres (255), Nitrons / ohlins, Brake disc upgrade to Tuscan S spec etc.

I would like to reduce the level of roll you get and see if I can get the car to react better to rough surfaces.
Over the past couple of weeks I have made a few decisions about the upgrade for the T Girl. As TVR are now no more and they never got around to developing an S spec for the T350 I’m going to do it myself, or rather I am going to spend the money and some very talented people are going to build it for me because I can’t build a damn thing!
What I am after is the sort of performance step-up that was achieved for the Tuscan mk 1 when TVR brought out the S spec . It’s about refinement as much as performance and so it means modes to handling and ride as well as an engine upgrade. I am also thinking about some mods for the cabin as well, sorting out the seats, the sound system, the detailing of the trim- nothing to do with performance but still stuff I want to sort.As part of research for the upgrade I took a trip today out to Silverstone Performance today to test drive Boss Cerbera’s T350 with the 3.8 Wilder engine upgrade.
This is very much first impressions based on a fast blat around country lanes near Silverstone circuit which was enough to give me a feel for the differences between the engines.
Phil took the wheel first and we spent an exhilarating few miles travelling very rapidly! Then he was kind enough to hand over the keys and let me have a drive (bare in mind we had only met about 30 minutes before that and he had never seen me drive!)
First impressions are very good. I was surprised that it was the smoothness of the unit that impressed me mos t-it feels very refined and mechanically quieter( The Boss wasn’t happy with the exhaust fitted but as I have the Power exhausts fitted at the moment it was quieter than mine). I can always hear a lot of noise from the head on the standard 3.6 but this was notably absent. It’s difficult to explain but even though I was not holding back the engine just doesn’t sound stressed at any point of the rev range and if anything it seemed happier at higher revs. The engine is also very tractable, pulling away in high gear with minimal revs without complaint and certainly none of the vibration I can feel when doing so with my current engine.
That’s all well and good but what I really wanted to learn was how much of a increase in power do you get and the answer to that is it feels like plenty! There is a notable punch in the back when you can really go for it and even in a higher gear the power just keeps building.
In character it’s very much a Speed Six experience ,the more it revs the more it pulls and it really loves to rev. On the first straight bit of road ( Ha! Dips and bumps and camber changes, bloody awful surface and as narrow as a stripper’s thong) I found myself reaching for gear after gear ,it really encourages exploring the top end and the joy is you can do so without worrying about what might be going on under the bonnet-it just doesn’t feel or sound as if its under any stress.
And neither did I, which has a lot to do with the SP12’s and the set-up of the test car because although the lane was dreadful I had real confidence driving at speed. I
Must admit that when Phil took me out at first I thought he might have been pushing it a bit but when I was at the tiller the car felt very well planted and the ride had none of the joggle and hop that you get on the standard set-up.
Sorry if this all sounds a bit over the top but the truth is I had a bloody good drive this afternoon and it has given me a lot of food for thought.

I've done the following performance upgrades to my T350: tvrpower 4ltr rr engine with power eprom and de-cats, the ACT carbon airbox with trumpets, tvrpower sports pipes, 330mm 's' spec discs with ferrodo ds2500 pads, nitrons, poly bushes and sp12 wheels.
The car is much easier to drive and more predictable handling wise, theres nothing i'd swap it for at the mo however as always i'd like a bit more power so its being re-mapped just now, to improve performance further would cost big ££££ and i can't justify it and the car doesn't really need to be quicker. Cant wait till summer to show it off at a TVR gathering as its in for a full respray just now so should be mint when it returns!

Phil was a bit coy about the specifics on the set-up but he put a lot of the improvement down to the wheels being 25% lighter and the geometry which he didn't want to say to much about at this point. I'd only just met him after all!
Good to meet you yesterday Steve. I didn't mean to seem coy - I thought I'd told you everything! The suspension is bog standard. Just SP's geo settings and SP12s shod with 225F/265R tyres. The improvement is primarily a function of the reduced unsprung weight but the combination of wheel offsets, front/rear tyre relationship and geometry we use for the T350 provides the balance of the gains. SP12 offsets differ from both TVR OE spec and aftermarket generic specs. Most people have come to realise that TVRs are very sensitive to small changes in geo and that relatively small adjustments make a difference - wheel location (determined by offset) is part of this mix. The next step up from this is Ohlins (which you've got!). Glad you enjoyed the drive/engine. Standard Speed Sixes feel pretty eager and smooth so I've found describing the Wilder engine as such kind of falls on deaf ears - you have to experience it to know the extent to which the Wilder is more of both, not to mention a lot more powerful and urgent. Just to pick up on a couple of points... tractable - we pulled off that roundabout from 950rpm in 5th. The reengineering of the engine is comprehensive but, as you noticed, retaining the character of the Speed Six was important. There are a number of factors at play which make the valvetrain run quieter and they're important to the perception (as well as the reality) of the engine's integrity.
It was good to meet you as well Phil and an excellent demo. Thank you for supplying the detail-we covered such a lot of ground yesterday I obviously had forgotten some of it! 
I am still amazed at the amount of development work that has gone into the Fury before you announced it but it is a great result and I very much like the idea there is more to come - when it's ready of course.
Good to see some positve development on the Six at last.
