4 valve DOHC engine aircooled Options

[bugat5speed]

Hi together,

I´m from Germany and have a company called Bug @ 5-Speed. Do a lot with Porsche 5-Speed gearboxes, sports shifters and other things. Have a new project running which is a new flat 4 engine for vintage cars like Porsche 356, 914, 912, VW Beetle and others. The engine is a 4-valve DOHC engine with a own crankcase with 5 bearings. Attached some pictures of the heads. I have molds for the heads and other parts and I have a own milling centre to machine the parts. The engine will give a reliable high power. We expect easy 100 PS per 1.000 cc. The capacity will be between 2.000 and 2.500 cc. The engine will reach high revvs (8.000 and more) and will stand this due to the 5 bearings of the crankshaft.
The design of the engine will be a little like the one of the old Porsche 356 Carrera engine. So it also fits vintage cars what concerns the look of it.

Am currently checking the interest of people and would be very pleased about replies to my posting. I hope that I´m in the correct column and that nobody of the admins minds this information.

The engine will not be cheap, as it is developed completely new. Can´t give an exact price at the moment.

Will check the forum regularly, but also would like to answer some mails on this matter.

Thank you for your interest

I inquired awhile back about a neat short cast aluminum pan for the suby that Martin makes. It looked pretty good. I wanted a bigger, gated solution that I got from Kennedy and Speedway. I also like to make my own solutions.

Martin has a lot of advanced stuff.

I found out a long time ago (from vw's and motorcycles) that heat sucks power out of a air cooled motor a lot. The harder and longer you run it the slower it gets. The more power it makes the harder it is to keep it cool. At some point water gets better at cooling high performance motors. Mercedes has a elect. controlled water thermostat for their new bad a$$ v8. I like that.
When you add a drysump cooler of course it helps but the heads never really get the cooling they need for high tech performance.
Guys that like to spend a lot of money on cars should like this approach as it will cost more than you can imagine but it will be pretty neat at the same time.

More power to you Martin, I'm sure it will be very interesting.

The dollar exchange rate might improve our prices in the next year too.
