- Many people here are discusing about BluePrinting as making
- your engine to fit factory specs as close as possible. This
- is true but a lot is still forgotten. You also have to balance
- everything (pistons, cranks...and clutch) to get a smooth
- running. This all is in the specs (weight of piston is xxx).
- Also volume of manifold openings should be matched on both
- sides on engine (they are in pairs, not the same). Volume of
- burning place (in heads above pistons - soory my english) must
- be the same. This is required to get same power out of all
- cylinders. It also effects on tremblings. Pressure of valve
- springs must be same and the rise of valves also. Actually
- easiest way is to thing the engine as one cylinder copied
- to 8 - everything is the same. Tremblings take a lot of power.
- Different weight, cylinder power and volumes causes this.
- (btw, compressor charger on a Dragster takes 600-800hp to run).
- A long time a go I read that saying 'blue print' comes from
- factory spec-papers that really where printed with blue color.
