[quote name='Judge Ito' date='May 27 2003, 08:13 PM'] This is not a Judge Ito vs Rob at pineapple porting thread. I actually know and have done business with Rob Golden and think he is a great person and I consider him a true rotary engine brother. At my shop I only do the porting for that reason, so I could control how an engine is being ported on a consistent level. I could only wonder that something like this might have been overlooked by Rob because he is probably Extremely busy with work.
When You say I spend hours making my ports look shiny to make them look pretty your a little off. I don't spend hours giving my ports the final details in work to make them look pretty, I spend time because through out my years of porting I have come to learn what works and what doesn't. From customers engine making serious power at low boost and customers engines making serious power at high boost. (15lbs of boost on a street port 459rwhp to 701rwhp street ported engine on 36lbs of boost with a nitrous shot in top of that boost on stock 2mm apex seal) I through the apex seals that I use just to keep convincing people how well stock 2mm seals work. From bridgeported to P-port from wild to mild, you name it I've done it. I seriously ported a 20B 3 rotor engine that we expect over 1200rwhp I'll keep everybody posted.
To close my comment I just think this was something that was overlooked, because Rob is an excellent engine builder and porting expert. Just my 2 cents.

I seriously doubt he is talking about Vosko's port. I'm thinking hes talking about the pineapple ports not being ported in the beggining of the port runner???

hmmm.. are you refering to the port being polished too smooth and the fact that it will cause fuel to form in droplets called pooling and cause poor atimization ... ? Or are you one of those people that thinks you need to cut out the lower and upper curved corners of the runner right next to the port opening?

So having the ports polished too smooth is a problem ? What about guys who polish rotors as well ? Any benefits to doing so ? Your honor (Judge Ito) ........what do you think ? Thank you.

I usually finish up with 400 grit roller drums.. they take out all the casting flash and rough spots, but still leave some scratches.. Once I've got it smoothed out I try to run the drum threw in a way that will cause the air to swirl in to the pocket of the port so it will get kicked in to the combustion area with more velocity and create a better atomized a/f mixture..
