For the first tests to runn the type 5 engine I did use a small electric water pump , but the engine was to hot after some minutes . Today I did use a bigger pump , still the same . So I started to investigate the radiator and got a surprise .
The radiator contains maximum 1 liter water !
Flow rate ,maximum 1 liter in 30 second !
What company made this radiator ?

regards Udolahr

Probably the man who made the bronze valve seats

Am I the only one who starts thinking that this Type 5 replica was never intended to be a runner, just a static "Mock up"? It seems that a high percentage of the parts are just wrong.

How about the other one, that was stolen while Richard Day transported it from UK to France? Did that ever turn up again? and.... was it of better quality??

I belive the bronce valve seats are made in a machine shop. And the radiator in a radiator shop .
Every part in this engine , I had to make new or machine it to fit .
So you are absolutly right with your comment , "It seems that a high percentage of the parts are just wrong."
I am not so sure about a " Mock up " , because for a Mock up I do not build camshafts and crankshaft bearings and so on .
Yesterday I got a comment in France ," The other one got stolen , because it was not much better ".
Who made this car ? I got the info Uwe Hucke started it in south France and later the car went to England to get finished .
And was the stolen one running ?

The stolen one was NOT running, see the news item from my site: http://www.bugattipage.com/2004news.htm

De Dietrich (Bugatti T5) stolen

A replica historic car has been stolen from a car park in west London en route to a French exhibition.

Engineer Richard Day woke up on Saturday to find the white van in which he was transporting the model 1902 Bugatti had been stolen in Hounslow.
The £100,000 project to build the working replica was commissioned for an exhibition in Strasbourg to commemorate its industrial heritage.
Mr Day, who built the car in Bristol, says the exhibition may be postponed.
He had stopped for the night on his way to Strasbourg and parked the van, which was converted to a specialist car transporter, in a car park.
"I woke up this morning and my worst nightmare came and hit me in the face," he said.
"Somebody presumably was trying to steal a white van and will have discovered what is inside.

'Devastating' news for team

"It will be difficult for them because, like an Old Master painting, it will not be easy to dispose of something like that."
But Mr Day, curator of the Cheltenham-based Bugatti Trust, said he felt devastated because he had been responsible for something that a lot of people had put "so much effort" into.

The full-size working model of the 1902 De Dietrich Bugatti Type Five was not fully completed when it was stolen.
The project to build the metal-framed two-seater car with Victorian wooden wheels was funded by De Dietrich with sponsorship from the local authority.
The van it was inside was a Mercedes 312, registration number T485 ANP.
Scotland Yard has confirmed it is investigating the theft of a "high-value" replica car stolen from the A4, near Harris Close in Hounslow.

About the radiator:

The type 5 was the one with tubular frame members, which held the coolant as well, right? The enormous surface of the tubular frame could definately help dissipate heat.

today I did check the weight , this radiator has 45 kg . How is this possible ?

They probably used thick-walled lead plumbing.....

Lead is no good. You will need copper, or aluminium.

I just made some calculations . It is a copper pipe with 8mm autside and 5.6mm inside .The radiator should contain 2.5 litter , what is still a joke for that size engine .
Best of all the 10 copper tubes are not in one piece . Each tube is soldered tugether from 15 smaler tubes . Each tube is about 65 cm long . So we have 150 connctions soldered together Yes 150 . I belive that some soldered connections are filled up with tin . So only some tubes are open , and most of them are blocked . This radiator is only good for display . For running the engine it is useless .

Who has experience with this kind of radiator ?

Perhaps company "Blaak" in Heinenoord, Netherlands.

The ones I have experience with, are Nissan Micra, and Ford Escort.

have you spoken to John Underwood at Star Engineering in Wales? He makes all the good radiators for Bugatti and bentley etc.

For many years I am building radiators , most time honeycomb . For example , radiators for the 15 liter Mercedes aircraft engine . Or the 1908 Wright Flyers .So I know how the water flow-through should be for a 13 liter engine .The bad part with the Type 5 engine is , that the exaust manyfold is inside the water jacket .

I really like these radiators. How do you solder them together? Using soldering paste, then heat up the whole construction in an oven or by flame?

First you buy brass tubing 1/4 inch (6,35mm) autside diameter and 0,2mm wall thickness , and 4 to 6 meter long .Sometimes not easy to get , so you need a company making it for you . You cut the pieces with a cutting blade .You need some speed and many very fine tooth . Best is to cut 10 or 15 at the time . Press the hexagons at both sides at the same time . Put all the pieces very tight together in a wooden frame . You need a bath with soldering fluid ( acid ), put the frame with all the tubes about 2cm deep in to the acid for some secunds . Next , you need a bath with liquid tin , lay the frame about 8mm to 10mm deep in and wait , so all the tubes have the right temparature . And you do it with both sides . sounds very easy , but make the first one !
