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
Oil groove for better Lubrication , Swivel Ball Adjusting Screws,
Modifed NOS VW Rocker Shaft
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.
