rnfried,

What is around, and under the steering column? One item looks like a Delrin bush, of some sort, the other a support?

Best,
B.

Hi Bernard, I do not want to live with a slacken steering column as it is normal for these cars. It´s a reinforcement, an aluminum bracket on what the outer column tube is fixed and a kind of a delrim bush as bearing for the column in its tube. There is another delrim bush on the other side at the firewall, see photo with the engine. Regards, A.

How about that rear window when driving at high speeds, is this window glued in?
so it stays in also with high speeds and high cabin pressure?

Hi René, the rear window is not glued in. The rubber gasket fits very tight so I hope that the window will stay also at high speed. In order to avoid high cabin pressure I built in a big vent to the bottom at the rear end. I hope that will work proper. I do not have any high speed experiences until now because the car needs still some work at the diff mount. Regards, A.

Hi Arnfried

... "wanabee..." racing, I know it's AN stuff, I have the same for my brakes and fuel. The thing is that they can allso be sourced in stainless and black anodized color. Mutc more understating and more classic imho. But again you car is stunning.

If you go to a TVR meeting in north germany please let us in Dk know.

Grüss

Thanks madsvlund! In case I am going to participate on a TVR meeting next year I let you know, Regards, A.

I like what you did with the rear lights very much. It's a small touch, but I think it makes a huge difference.

That car needs a set of TVR inlet manifolds fitted. Would look the dogs @&*#'s!

Where would one acquire such an item?

Hi B.
I am the keeper of the original mould that TVR used for their Le Mans cars.
If anyone has an interest, please send me a PM.
Cheers,

Hi Grantura MkI, I guess the best inlet manifold for this car at all are the "Derrington HRG 45" ones which belongs to the rare HRG Derrington crossflow cylinder head. And exactly these parts are in. I don´t know what you mean about "TVR inlet manifolds". Regards, A.

They look Rather Fantastic a nice finishing touch

Thank you Andrew, I never have seen these manifolds before. I am happy with my ones. Anyway – the developer of the crossflow cylinder head was not TVR but Derrington HRG. I can imagine that reals TVR fans wish to meet their favorite logo everywhere

Regards, Arnfried

These were developed by the TVR factory racing programe in the 1960's. I am not suprised that you have never seen them. I was lucky enough to be in the right place at the right time and purchase the original molds.
Enjoy your TVR,
D.

They look pretty st to me and would need a hell of a lot of work to make them anywhere near as good as the Derrington manifolds !
They have TVR cast onto them though so no doubt that would make them seem faster

As they are just out of the mould then I would expect that
I guess your door stops (uprights)looked that way before some work was done on them

Now thats the sort of feedback than I needed. I will be straight into the foundry first thing in the morning. I will inform them that I have had a professional surveyor do his job and survey their work. They will be told that the castings are rubbish and should come out of the mold ready to fit.
Fingers crossed that they return my money!

If you want TVR written on them then they are good. If you want them to be as good as the period Derrington manifolds then they will need countless hours porting and most probably material adding to them. if you look at the Derrington versions they are very neatly swept and change in port diameter over their length. It may be the photos but the TVR stamped affairs don't. Why don't you do a back to back test on Arnfrieds car and prove me wrong? The castings look like castings bye the way and perfectly fine. My comments were related to their form and design which may have been something similar to what TVR cast on their own back in the day but ultimately not as good as the Period tuning companies products.

I will look forward to the back to back power print outs.

Do not hold your breath...I am not a bench racer.
The last TVR that I fitted these two had a Huffaker MGB motor. It would not be fair to put it up against other lumps...regardless of there intake set-up.
You can have all the power in the world, but at the end of the day, it comes down to the talent of the person behind the wheel!

I see, thats going to be exciting then when you take her out when she's ready for it
But indeed a good valve/vent system in the car could work very well.
You see a lot of those cars with vents in the rear glass but then you have to be a bit careful with water, but with a good working valve/vent system you don't need the "glass"/vents.

A long time ago I saw for the first time in a BMW Z3 how those cabin vents/valve's work, those were rubber valve's which open when there come's pressure say by slamming the doors or on higher speeds, but they also close themselves when pressure goes lower etc.

You only have to find the best ways were to fit them and to cut them in

So keep us posted how you solved that with such car.

Fabulous castings. How can you say they were from the original TVR castings. Mine were factory original and said HRG on. Assuming yours were factory "Le Mans" spec and other,s weren,t how can you prove it and regardless, any performance advantage? How much increase in bhp if any? Who cast them ? Got invoices? I am not saying the moulds didn,t end up in LA but it would have been more likely they didn,t!

I know who made the bumpers and rear uprights. Did they make the Le Mans HRG style inlets???

Hi sTeVe R,
I have PM you with several pictures. Never claimed HP boost with these units. I am very familiar with intake manifolds that work well with Webers, as was the factory.
Best to you,

Slow M said:

Arnfried,

I did have one picture of your M with the Alu wheels.
Yes, The dark ones suit your car so much more.

I made a hard sunroof panel for my M. It won't add rigidity to the body, but it shouldn't leave, either.

For the windshield, I'm considering "buzzard bars," or a mirror rod, to connect the upper and lower windshield "frame."

I suppose, when you get those last few details sorted, you could try a cam that moves the power band further up the rev range, to take advantage of all that breathing, at the top. Then, a 3.31 gear, and (theoretical) 267kph is in your pocket.

Best,
B.

Hi Bernard, I do like your enthusiasm. To achieve 267kph is not my goal even when I live in Germany with no speed limit (.. at certain parts) on the "Autobahn". I am going to leave the engine and the diff as it is. A car for the road with a weight of less than 1000kg, an engine with 233hp and a five speed gear box makes a l lot fun. To people who are looking for historic cars as a nice accessory the brand TVR seems to be underestimated. I guess they do not understand what we like and how much fun we do have with our toys. Find here another pic of 3142TM with the dark wheels .. for your collection . And interior pics as well. Regards A.
