The Typ3 Engine Project

The Typ3 Project starts something different.
Normally everybody asks for more displacement, but not the owner of this Project.
 
The car is used for vintage rally`s and sometimes it is used to pull a trailer with a historical Formular Vee.
So it was clear that the max. was 85.5mm Bore.
The next challenge was that it must have a closed engine compartment lid
 
 
 
Starting with a new AS41 VW Engine case
 
For the crankshaft it was the owner choice to take a NOS 69mm VW Crankshaft
 
8 doweled with I-Profil balanced rods with ARP2000 bolts
 
 
 
 
 
Close to 100 Gramm ligther wrist pins is always a good choice.
Try to remove 25g per Piston :-) 
 
 
 
Shortblock assemply with thick washers
 
37cc combustion chamber, the first cooling fin is gone
40 / 35.5 Valves
 
Lonblock with CSP Oilpump Cover
 

 
The cooling fan was welded and balanced with that large diameter ist a must for me
 
Upside down of the Longblock
 
CSP Phyton for Typ3 attached with the super short and curve manifold it is a challenge!
And you can`t use airhorns with the flat airfilters



 
The engine after Brake-In,
 
after the installation in the car it was once more a challenge to find the perfect Setup of the carbs and ignition to have no flat spot.
But we found the perfect setup and big smile on the face of the owner after the first testdrive told us.
 
Mission accomplished

Swiss Camper Special Assembly

The longblock went to the customer for final assembly.
He did a lot of engines overhauls, but only stock engines so he was happy do get this performance engine ready to finish.

On this photo you can see his self made stanless steel heater boxes


Engine is assembled an ready for the Break-Inn. Very nice assembly! Well done :-)


Engine after Break Inn

After all built-in to his nice Bay Window Westfalia.(weight: 1850kg or 4080lbs)
This is a very powerful engine together with the long transmission from the 2L Typ4 it is perfect to travel. Even with this weight it is easy to overtake or hillclimb.

Swiss Camper Special Part 2

 
There is always a lot of handwork to do ....


 
This is the layout for the rockers that I like
CroMo M8 bolts, SW15 Nuts, solid spacer and Porsche style adjusting screws


Shortblock
 
Checking the piston residue
 
 
JPS custom pushrods will replace the stock pushrods
 
 
227g weight improvement with only the pushrods .....

Swiss Camper Special

New Engine Project is the "Swiss Camper Special", the goal of this project is to build a TypIV Engine with a lot of torque and power and the full reliability to push a heavy Westfalia Camper.

It`s no secret that I`m a fan of the TypIV engines.
For me it`s the perfect Bus engine!

Especially when you but in some goodies like this:

96mm AA Biral Cylinder, a good choice
 

Measuring the valvepocket volume

 
Backcut grinding on the 44mm Manley intake valve

 
Machining of the new AMC cylinderheads
 

 
I don`t like the M7 rocker studs, I replace it with custom M8 CroMo rocker studs

 
Manley Line-up

 
Longstroke counterweigth crank with H-Profile rods and ARP 2000 Screws.
This crankshaft have an additional Tenifer heat treatment is polished and balanced
 

 
A big improvment on TypIV Engine Cases too:
Gene and Gary Berg case conversation invention
 
Thick washers a perfect flat surface and the correct torque!

912 Engine Project Part 2

 
It takes some time to have all parts together for a nice build Porsche 912 Engine.
This engine will have it all.....
 
The 912 Crankshaft after polishing looks nice
 
the new lifter where checked for the cambered surface
 
Looks good!
 
The Lifters are all in tolerance but I like to pair it with the rigth lifter bore
 
New JE Pistons, 2g difference that`s too much for me.
I`m a little disappointed about that, because a high price piston like that should be better in tolerance.
Anyway I brought it to 0,2g ;-)  
 
 
AA Cylinder: Measuring the length, the Ø and out of round all where perfect :-)
 
Backlash and axial endplay of the Camshaft
 
Good fit of the Rods!
 
Dial in the WEBCAM Camshaft
The quality and finish of WEBCAM is very good
 
 
Just to compare:
 left 912 Pushrod
mittle JPS custom Pushrod for this engine
and the VW Typ1 stock
 
The weigth of 8 Stock 912 pushrods :-(
That`s too much in weigth and they where too long too!
 
Ah, 202g ligther than stock!!
JPS Aircooled Aluminium Pushrods for Porsche 912 Engine, you have the correct geometry with the rigth length and reduction in weigth too.
 
Win win!  
 
 
 
The combustion chamber after masching!
On Porsche 356 and 912 engines the combustion chamber are not equal you have to fix all
 
The 3. Piece in place with CSP Oilpumpcover
