DOHC 4 valve heads - current status

[Bugat5speed]

Hi together,

just finnished the current batch of cylinder heads on my milling centre. Attached one picture of 4 heads. Cutting the fins was time-killing, but after the first head was done the mill did it whilst I could do other jobs. Since the 1st batch in February some changes were made to the mold (inlet channel, position of valve seats, etc.).

Robert Bernauer will get them the next days to accomplish them with valve seats, guidance, valves, etc.

The camboxes are nearly finnished, also the manifolds and other parts.

Hope to give you more info soon.

Martin,

Very nice, looks so much better in alum, compared to the prototypes you showed me while we had some beer's last years.

I will show Ana, the progress, but I know she won't truely understand.

Hi Martin,

Those are awesome! I am really looking forward to this.

What are the details, your vision for the engine?

-displacement
-based on which case
-cylinders
-street/race
-fit in the stock engine bay
-cooling system

Could this be a reality in our street cars?

What is your timeline?

Sorry for all the questions, but if your looking for a test vehicle in North America, let me be the first to volunteer!

Hi Pete,

some answers to your questions:

own case (molds are just being built, engineered with CAD like the heads also)
Porsche cylinders, custom made pistons
street or race, whatever is wanted
engine is only 1-2 cm wider than an original type 1
something in classic style (f.e. like Jake Raby`s project)
will not be a cheap option, so it depends what you want to spend for your street car
timeline is much depending on budget. The things cost quite a lot. We want to have a prototype running in autumn
what is meant with displacement? Sorry for this stupid question, but my English is not perfect.

Hope to have given some details for you.

Thanks for your interest in the project.

Martin,

No worries, your English is great. Displacement is the size of the motor. 2L, 2.5L, 3L?

As for cost, what kind of money are you thinking? How expensive? You can message me.

Thanks, and i'm looking forward to the updates.

Great progress Martin!
Its a pity (imo) that you didn't choose the type 1 or 4 engine case as a base to make the heads onto. Any particular reason why you and Robert choose to also have a totally new engine casing type made for these?

Is cylinder spacing larger or similar to type 1 or 4 (or 911 perhaps)?

Thanks,
Walter

Any updates to this project?

Hi, I have just seen this post (late bloomer), why not take the type IV to the next level? And then there the pricing, all the way to the moon, wow. At one time I wanted a large displacement engine, but priing went through the roof 4,000.00 US for a set of heads. It makes for a slow build, I don't know about most members but I am a lowly diesel mechanic. My money does not come that fast. It would have been nice to hear that you sold your parts to thousands on this planet; not hundreds. There will be those that will buy, I'd like to see you be a seccess. High cost of parts and slow buying will effect your investment. Just for an example, look how the type IV market sputters, it should have really taken off by now. However 1000.00 pistons, 2000.00 cranks, 4000.00 heads, 1000.00 connecting rods. I think CB Performance is doing it correctly, not too high in pricing. O well . A good type IV case that would ealily reach the 3.5 displacment, and use none grommet type of oil cooler interface; would have been great.

What about the type 5 engine (Vanagon oxyboxer)? Not sure how many ribs the case has, but from what I understand they're supposed to be a lot stronger, can be converted to accept type 1 crank and heads, and run air-cooled.

progress?
