Coffee Bean final assembly, Roaring Fifty Project

Final Assembly of the Coffee Bean Engine

 

 

87mm AA Pistons, I prefer the AA Pistons over the 87mm Mahle

Reason:

Better Pistons, not out of round, Pistons have the same weight and I like the honing of AA

 

 

Heads on, Oil coiler in place, JPS custom pushrods for sure! 

 

 

 

Nice Powder Coated Tins

 

 

The last step was done by Pädi!

Good Job, Looks beautiful

 

Only a few parts are missing and than we can start this nice street engine on our engine test bench and do the break-in

 

 

Next Engine Project:

 

Roaring Fifty, or Walter is hungry for power

 

 

Coffee Bean Part 2 and other Infos

Happy New Year to all my Blog followers!

 

 

This is Part 2 on the Coffee Bean Engine Project:

 

Maschine work already done!

Combustion chamber have a new shape

 

Volumetric measurement the combustion chamber after machining!

I will do it again after finishing manual work

 

Rocker work:

Oil groove for better Lubrication , Swivel Ball Adjusting Screws,

bore honing

Modifed NOS VW Rocker Shaft

 

Compare

German rocker above

Late style Mexico or Brazil rocker below

 

 

 

I don`t like the Mexico Rockers!

 

Modification on the intake Valves, Backcut with radius for better flow

It`s not done in 5 minutes ....

Measuring the Valve Spring for this engine

Seat preassure is 38,5 kg

At full lift it is 92kg with 1.5mm shim

 

With the light lifters, JPS Pushrods, modifed rockers and light retainers you only need single springs for up to 6200rpm

 

 

Some other Projects are done!

 

Westfalia Spezial is this nice Typ 4 engine called:

96mm AA Pistons

NOS 412S heads machined for higher comression with 41mm / 34mm Valves

and a good torque camshaft

 

This is a nice upgade when you rebuild the engine!

This is another Super Stock 1641cc this time with dual port heads.

 

Coffee Bean Engine Project

The Shortblock is already together

In this post we want to take a look inside .... 

 

 

Starting with an Industrie engine Typ 126 that has a slighty more than 3h run

                                                             Looks like new!
                                   

 

Crankshaft is a NOS German forged F-Typ

Dynamical balanced for sure!

Flywheel and Clutch too

The wrist pin of the AA Piston 87mm is too heavy

27g less than the AA, we take this one

An average weight Typ1 rod

556g in total and very good balanced, wit ARP bolts

 

Hmm let my remeber: 4x27g - wrist pin, 4x59g - rods, 8x22g -lifter

 

That`s 520g lighter than stock :-)

Here it is in the Case

The other goodies for the Coffee Bean:

Silverline Main and Double Thrust Cambearing

Clevite Rod Bearings

CB Ligtweight Lifters with 72g

As for all HP Engines

Thick washers and SW15 M8 nuts

The Pistons Need some honing because the wrist pin are too tight

Fabian`s idea for a Christmas present

 

A wine bottle holder, like it!

Super Stock Singleport

Not everyone is looking for the ultimate high-performance engine for its air-cooled vehicle.
Most of you  just want to ride with your well maintained Oldie with the regualar traffic. The problem is always when you need power for an uphill or to overtake a slow vehicle.

Than you may want to have a Super Stock Engine like this?

Looks completly like a Stock but ....... more powerful.

 

The reason to rebuild this engine was a loose Flywheel

This destroyed the crankshaft, the engine case

 

 

 

Broke all! Top piston rings

 

 

Broke two pistons...

 

 

Time for a new set of single port heads

This one are milled for an adequate compression Ratio

the intake is matchported to the EMPI SP Manifold

 

 

Longblock wit 87mm AA Piston and Cylinder a Camshaft for better torque and power.

Be careful with Singleport Heads and Camshafts, only a mild Duration will work with this! 

 

 

 

In-out pump and an additional oil sump will help to keep the engine temperatue in the right place on a hot summerday in a T1 :-)
