All you speed six owners who have/are giving your engines some breathing space should take your cars along to Spa. two day event on the 27th July.
Hope to catch you soon!G
If Andy Race is not doing the pilgrimage this year I am going to book another trip across to Spa. Why don't you come along and maybe there is others who might want to indulge stretching there horses legs and joining in. It is such a shame the TVR track days have died it was a good social event with good people. I am going to Donington in September with Book a Track (Unsilenced)if that interests you and others as well.
I find it quite odd that you go to spa for example and it is chock a block with German and Italian cars, you have Lotus that has a very healthy track calender but TVR is one of them makes that folk just want to polish, I just don't understand why when you consider the history and speed of them.

I suppose because to some degree TVRs are thought of as fast road cars not track cars. The Lotus Elise is the other way around. However when you factor in the very low weight of TVRs allied to the responsive, race-inspired set up from the mk 1 tuscan onwards, they do actually make very capable track cars. It seems it's also easy to forget that TVRs have considerable (for a company of their size) race history including finishing several class wins in British GT, a very popular Tuscan race series and even competed at Le Mans!
Trouble is, unlike a 4WD rice burner you have to know what you're doing to get the best of a TVR on the track.
It's great to see them used on the track though. As mentioned elsewhere I was at the Nurburgring in my Sagaris when a black mk1 tuscan S appeared in the mirrors, gaining at a rate of knots. I had to up the ante (considerably!) to keep him in sight for the rest of the lap. Its was great to see one being driven like it was designed to be. It was really flying!

Then try and do all TVRCC trackdays there are
Are there any Graham ? I thought they threw the towel in on the basis it was to much like hard work and would rather have another meet to talk about what they talked about last time, Edited to say I have just looked on there web site and they are still advertising the 2008 season. They don't even know what year it is.

Mark, once mine is re-mapped correctly will see about getting the 4.3litre & re-engineered cars out together.
Shame not too!
I will be running mine in on track at oulton park as its local, as is donington.
Then try and do all TVRCC trackdays there are.

I'll be up for a trackday too guys, Oulton or elsewhere, avoiding clashes with competition dates. Would be fun comparing our variously modified cars, and I'm not fussed whether it's TVR only. Shame not too!

In fact, joining the Lotii, Porkers and Fezzas can be childishly amusing

Yes i would be up for this to depending on timings etc.
Good - maybe should start another thread then - Graham?Would be good to entice any modified Tams/T350's/Sags to a fairly central trackday.
Mine's only been set up on dom's dyno to make the most of it's 200 cell sports cats. It's hardly what you'd call modified. I prefer 'optimized'. But hopefully it still counts! I hope to be taking it to le mans for a trackday on the bugatti circuit at the end of may. Goes without saying that it would be nice to see some other trevs down there!
I have one of these Engines now in my Tuscan. Having taken the trouble to go and meet Dom, and having met a lot of people in this industry, I was very impressed with his strait forward approach.
My Tuscan was a 2000 4lt “standard”, with 24,000ms, no rebuild. Engine was good, but valve guides had wear, so oil consumption was a bit higher than normal.
I was only interested in a rebuild with increased performance, hence the appeal of the 4.3, especially with the 5 year unlimited mileage warranty. I left my Car with Dom after our meeting, not expecting to do so, and just over 2 weeks later, it was ready for collection.
Dom’s running in advice is very sound, not to much pussyfooting around, but obviously warm it up correctly, and no labouring, and as little M way use as poss. I am a great believer in running a car in a quickly as possible [ time, not speed!! ], so did the 1000ms in a 3 week period. It was immediately apparent that there was a Big increase in torque, making it easy to run in. Mechanically still like a typical Sp6 although this decreased when the semi synthetic oil went in. My Oil pressure was also lower, before rebuild, mine had 60psi on the go, and 18 on tickover. On the running in Oil, 55psi and 8 on tickover. Dom confirmed this was fine, and would increase when the oil was changed, which it did.
TVR power fit a running in chip, and very sensibly do not allow full throttle. They also use normal mineral Oil for the running in period. Consumption was minimal during this time.
Andy at APM is approved by Dom to service his warranted Engines, so before returning to TVR power, I went to APM for the Oil change to semi synthetic, filter and tappet check, plus a look at his insane Drag bike!
Next Day to TVR power for the RR set up and re map, plus abuse from Dom!
After they set up the throttle bodies which had a couple of weak springs in allowing them to flutter when the engine was running, the re map took place and power run.
Mine has standard exhaust, de-catted and made 360bhp @ 6250, and 347 Ilbs torque @ 4800. Both power and torque curves are very linear. Working on 15% loss, this is as near as dam it 415 BHP, and 400 Lbs torque.
The drive home was Great!, now the engine really comes alive, Big torque, great power and very smooth and mechanically quieter. I don’t think the rear tyres will last long!
Oil pressure tops at 65pi and is around 12 on tickover.
I thoroughly recommend this engine, especially with the warranty it comes with, the car was quick before, now its ballistic!
Talking to Dom, its quite apparent the exhaust makes quite a bit of difference, the one quoted on TVR powers web site at 430 bhp and 390 Lbs torque was an S exhaust with another induction kit [ cant remember ] for more power but less torque.
Hope this gives any potential 4.3 owners an insight.

We will see you at Cadwell then on the TVRCC track day in September. The more modified TVR's the better.My Tuscan was a 2000 4lt “standard”, with 24,000ms, no rebuild. Engine was good, but valve guides had wear, so oil consumption was a bit higher than normal.

It has been a while since my last update on the Power 4.3 because I wanted to wait until it had been run in and I have had a chance to stretch its legs. It’s taken some time to get here, partly because my exhaust is none-standard and that led to a bit of head scratching and some late nights at Power as it wasn’t quite making the numbers, and partly because of a clutch issue ( TVR’s hey! Immaculate timing)
Dom being Dom, I wasn’t going to get the car back until it did make the numbers so it’s been living in Coventry for a little bit longer than originally planned. Dom has been a star burning the midnight oil, so has a certain ex TVR engine designer/developer who will remain nameless but was more than happy to contribute. Talk about dedication and pride in their work!
So finally I got my hand on the car last night at around six (I want to mention the Trimar team as well who sorted out the clutch problem in a day) and was able to try it out properly.
Now I live 8 miles from Trimar, but it took me nearly three hours to get home. It’s a completely addictive experience the 4.3 and I simply could not stop driving the beast. As soon as it was hot enough I let it have its head. First impressions past 4k are the power just keeps on piling on with no sign of letting up. It’s also incredibly smooth, maybe due to the very high spec crankshaft used (it’s a damned expensive item) maybe just due to the care in the build. I have not really spanked it yet, I want to let it loosen up a little more, but I have not detected any tailing off at the top end as has been suggested for a longer stroke engine. It might be there but I cannot detect it. Also it may not rev quite so freely as a 3.6 due to the increased inertia, I am not sure yet as I may be imagining the difference, but it certainly loves to rev and never feels ‘strained’.
The torque is a big step up and redefines the character of the engine and the car. I used to love revving the nuts of the 3.6 and it seemed to love it as well, but now the torque means you can cruise along in 4th or 5th at low speeds and then, with a flex of the foot it will surge forwards. Just for fun, I stuck it in 5th and dropped the speed down to 30 then gave it some gas. It was a bit like a jet taking of, that firm push in the back that builds and builds with no let up unstill you are at ‘interesting’ speeds. No bogging down, no fuss, just more and more power.
That's not driving it properly though.Rev it and it's wonderfull,a really good step-up from the 3.6 and you'll be reahing for the next gear and wanting to do it again and again.It feels a lot quicker subjectively,which is what it's all about after all.
Long post, didn’t mean to go on quite so long, but one last comment on the sound. It’s definitely different, richer and deeper from tickover to flat out. The 3.6 used to shriek, a really angry sound which was great fun but the 4.3 yowls, as the citizens of Oxfordshire and Berkshire learnt last night.
Yes, it is a noisy engine, but it is a fabulous noise!
Big thumbs up from me and a big thanks to Dom.

OK then I'll ask, what were the numbers in the end then Dom being Dom, I wasn’t going to get the car back until it did make the numbers so it’s been living in Coventry for a little bit longer than originally planned.

It’s the big jump in torque that impresses me the most, making it a really nice Road engine.Yup,sure are. Big grin time! I agree about the torque being the big benefit.It makes for a very different drive and although I loved the rev crazy 3.6 the 4.3 feels so much more relaxed.Did Dom talk to you about the Supercharger option for later on ( next year?).
On numbers I am a designer,I don't do numbers. I have just asked Dom what she made on the final run so more news later.
