I saw this at the Maikäfer show last week. Presumably high output street heads.
I thought some may like it.

Not yet, that single head was almost still warm from the mill...
Nice idea though - I like that layout better than JPM.
I think they should add the rocker support like JPM has though.

More and thicker fins = Better cooling?
Maybe someone should do that with a type 1 head

Should make for a pretty wide engine, in any application. They look like they are cut for semi hemi? Or the chamber is very small. The casting looks like a 10 pounder.

Those are some deep heads. No need for manifolds just make intake bolt pattern in IDA and your good to go.

That is the very same head I held in my hand! Someone asked me if I was going to make copies at home when I took several pictures of it. I won't by the way.

I'm not convinced by the fins around the exhaust port. They look restrictive to flow and counterproductive. There needs to be flow around the port and the fin spacing ought to be even around the circumference

Ah ha!!! Now I see the type 4 intake and type 1 exhaust....pretty cool. $2800 huh? Yeah, I'm a little short this week, will you take an IOU?

Those heads look ridiculously heavy. I don't see any advantage using them.

They were not ridicolously heavy. And they have much better ports than stock configuration.
You know, like they try to do in racing.

Extending the fins around the exhaust port is just going to conduct heat back into the head, and the extra fins below the ports aren't going to do much that's useful. Impressive bit of machining, but I think you need to have a competent engineer look at the design.

X2. Looks like they were adding fins just for the sake of adding fins with no real regard as to their function.

Way cool!
Although I kinda agree. If they have made it so the tins won't fit, then there was no need to keep the fins stock outer dimension. Should have gone another 6mm bigger!! |

They should start producing matching cylinder tins to go with those too.... Is that an opening for the thermostat connecting rod?

Yea, tins are a problem. Unless you have a baja, which wait no, it's still a problem.
Bugguy, these are race application heads, which need no flaps not thermostat. oh wait, they're marketed as street heads.
So constructive criticism: they need to be re-"engineered"

I think the holes through the middle is for air circulation, but I guess a thermostat rod could go through there too.
I'd say they would require much less tinwork than MS230/250.

Special 'tins'will be availible for stock fanshrouds as well as Porschestyle cooling.
The heads are only slightly heavier in weight and take stock rocker+shafts.
Valves are 45/40 or 45/38 Nimonic.
Btw.Edy Remmele(whom's outfit makes these heads)was quick to point out that these are prototypes.
He also makes type4 heads in various configurations-all his engines are built for driving beyond the quartermile mark. |
