Fuhrcam engine development

Nigel - That is an awesome project you have going on! Carrera Speedster being the Holy Grail. You're more than welcome to share progress pics of that magnificent 4-cammer with this replica Speedster group! 

Welcome (back) to the Madness! 

Thank you for your kind comments, this is not actually a  4 cam motor, but a 356 1720 single cam engine. So not a true 4 cam but a replica.

Here are some more detailed shots of the manifolds I have developed.

Amazing fabricating skills, Nigel! Looking forward to seeing progress pics of that awesome engine!

wow, more please.

Lets start back in the begining the first task was to create the generator stand. The three piece Porsche engine is a very different shape to the original 4cam block so created a considerable challenge. My ethos from the start was that this had to be a bolt on conversion so that the engine could be returned to original if required in the future.

The photo's attached show the development of the sand cast mould tool and the finished item.

Dude,

More. Seriously. Crazy cool.

way cool................aren't you the same bloke on the 356 forum?

there is a very good chance that some of us may become your biggest fans........

 (no pun intended)

Very interesting project to me Nigel as I am working on getting my IM Carrera Speedster to look as close to the real mark as possible without adding a real 4-cam. I would love to see some more pics of your project but it might also be cool for you to "shed" (could not resist the pun)some light on your work space. Thanks for sharing your project, drive on!

Awesome!

Will these be mass produced?

WOW!  That is super cool and he's doing it all in a shed.

Did you catch the part where he's hiding injectors inside the faux upper valve-covers?

Genius!

Vinny AKA El Diablo was the originator of the "Fuhrcam" 

Thank you for the great feedback, I will take you through the development of all the parts of the engine parts. In response to the questions asked. Yes I am the engineer mentioned on the 356 Registry FauxCam thread by Bill Sargent.

All the parts you will see developed for my car can be reproduced to order as I have all the drawings, patterns and tooling sat in the shed. 

To give some more detail on the manifolds regarding the stealth FI, here are a few more photo's showing the fuel injection options. The primary injection is low down to produce more torque and responsiveness, this works well as it can be installed completely stealth especially in a Coupe and a Speedster as the fuel lines exit out of view and run behind the rear tin.There is the option for max performance to run a second set of injectors in a pair of throttle and control them via the ECU to come in at high revs thus giving superior fuel air mixture when required, but this is only really needed if you were competing and a bit overkill for the street.

The manifolds also work with Solex P40-11 Carbs the injector ports are not drilled. I have converted a pair of selects into throttle bodies.

I will go more deeply into the CAD design work behind the manifolds and the computer flow modelling and more in my next post. 

Thanks for following along

Beautiful work! I'll bet that looks and performs well. It is a testament to all DIYers, that you CAN do this if you put your mind to it and stick with it! 

Now you have me thinking! If I ever do EFI on my type 1, I could do the fake intake cam box welded to the intake manifolds with injectors. Take the insides out of a set of 44 IDFs and turn them into throttle bodies. SWEET! Along with my faux P valve covers on the bottom, it would be a good look.

Holy Crapoly, that's nice.

This is insane! Brilliantly insane!
