partnership? the benefits are obvious for both sides

Ah, see what you mean there Jake. The sideway clearence is what I meant originally.
Don't think the cam drive has been test fitted already, but he has made an intermediate axis for the left bank, so clearence for that left bank would be enough probably
Time will tell.

Roberto,
do that... And perhaps you could sell my stuff there in return???

That may work well. If you speak OK english we could talk on the phone as well.

R&D could get done much faster this way as well because of the number of projects that we have going on here and your own test engines..

I hate to change the subject but if you get the heads perfected for the type 4 will you consider development for a type one.

Sorry, just day dreaming my own 1600 carrea over head cam engine. It would be like Porsche's over head cam engine but minus one cam and a whole lot faster.

Well you can do it with a Type IV and have a much stronger foundation.

Don't get me wrong I know the type IV by far a better desighn and I would buy a set of these heads for my 914 before my Ghia, but I just love the little type one. And its a fun challenge to see just how far in the future you can bring it.

actually, you are not really changing the subject-
Ludwig Apfelbeck designed a Type 1 head first.
He is writing about some hillclimb racing with this engine.
Maybe he was "overtaken" by Formula Super Vee
before doing much with that.

Apfelbeck's book is still available on Amazon.

is this for real!?!

so hopefully we could all be running a 12 valve, twin spark, overhead cam type4 one day!!!!

AWESOME

YES, if you have the $30,000 necessary to PAY for it.......
NOT to even MENTION, the maintenance on it.....


Jake, don't give up on your heads

The VAST majority of Type 4 enthusiasts won't even be able to afford to DREAM about heads like that.

We need heads for around $1000 each, that will take a 2L to 8K, won't overheat doing it and make POWER.

Well okay, I need people to commit to them first before I'm going any further.

5 out of the 8 guys I had already verbally commit to my heads are now going this way if at all possible and to them money was not an object..

Apfelbeck heads are definitely a gem-

and there's a whole world between stock Transporter heads and ohc.
IMO Type1- or 356 style heads, 356 for the angled exhaust valve position,
will do a good job for a street car.

there's still a big questionmark behind Apfelbeck-
where and how to get rid of the heat off that massive piece of an aluminium head ?
Will this at the end limit those heads to an application for quartermile racing only?

Apfelbeck, btw. would be someone for some tough discussion with Jake Raby.
If i have understood his book just very little,
he was pleading for an ideal of a completely closed cooling jacket
for every cylinder and head- which he accepted to be impossible though.
Jake, if I remember an earlier posting right, just leaves away the under-cylinder tin.

Now please don’t get confused neither of you, both go ahead!

Good luck to both of you!
