Ito san.. What kind of side seal to corner seal clearance do you run on higher hp turbo engines? I'm assuming that a long side seal will expand more than the apex seal does.. I usually run a .015mm cleance and I've had no problems with blow by, but I've also heard that a tighter clearance will pick up 10 hp or so..
Dragon I see you want to get the good info. Side seal clearance is responsible for some nice equal compression on both rotors and extra power. I clearance side seals according to the application. N/A or turbo application. Ill reply later with my specs I need to surf to pineapple racings website for some pineapple racing 6port better flowing sleeves. Ill be back. Im building a bridgeported 6 port engine and using the stock auxilary sleeves with the 5 and 6 ports bridgeported also. Ill make sure to take pics. So far it looks like a wicked port.This engines is going to have 12 port openings using the 5 and 6 port sleeves for low rpm torque and opening at around 5,500RPM. I want to see how much power increase the bridgeported 5and 6 port will add to this engine when they open.

itos neighbors must be used to the smell of burning rubber. I've seen plenty of videos of huge burnouts in front of his shop and those are only the ones that were videotaped and uploaded

Alright, Jude Ito, your honor, how do you keep the apex seal end square when you are reducing the length? Any tricks you know? I was extremely careful and it seems quite square but not perfect. I am assuming the ends wear in after break-in so it is not extremely critical to have it perfect. Any thoughts?.........
