port and polish

[SkYwAlKeR]

can we obtain same result with manual p&p compares to CNC m/c ??
anyone? coz CNC damn xpensive lor

vr difficult... if can be done easily, humans wouldnt have invented cnc machines....

Correct, CNC (Computer Numerical Control) accuracy is about 0.005mm or 5µm.

But IMO, there's only a certain extent CNC can do its job which still requires porting by hand. A bit of inaccuracy or carelessness in initial measurement could jeopardize the port work? No kah?

yeap... thats why we have bench flow testing... for a common engine, the specs needed to pnp a cylinder head is already tested hundreds of time thru R&D...

but for a new engine, bench flow is needed to try and error on whats the best spec for that particular engine...

Sifus, could you share with us which professional workshops that have a flow bench & high precision porting tools that also guarantees improved airflow?...i'm afraid most of us only knows of Powerzone & Matspeed where other alternative tuning w'shops would also be useful for our future reference...many thanks...
