Spyros is the man! reading all the posts he has in that thread is awesome. When i built the original atmo 1.9l 8v in Preens mk1 it had 42mm inlet 35mm exhaust valves, schrick 272 cam, porting and polishing, 10.5:1 compression, fully balanced, lightened flywheel, 1 5/8" 4 into 1 tuned lenght extractors 2 1/2" system and running on twin down draught 40mm webbers etc. The list goes on but my point is it was essentially totally worked for a nicely drivable street car but only made a maximum 170bhp. It is not easy to get big numbers from an atmo engine and keep it driveable or do it cheaply. I like webbers and ITB's but for out right power forced induction is the way, keep the revs down to below 8000rpm max and vw's respond very well to psi..
