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.
