This picture here is the actual size of the template.

Looking very nice Ito!



how do you go lining the template up so it is lined up with the port. Is there like a common hole in the template that say lines up with the thru bolt hole/s on the iron?



cheers

Lance, it lines up using the two dowel pins. It's going to be one template sporting the primary and secondary ports 2 in 1

Thats a good idea!



i must say i am really looking forward to the big street port one https://www.nopistons.com/forums/pub...IR#>/smile.png

Ito,



In that pic above, it looks to me like the distance from the edge of the o ring groove to the intake opening is around 10 mm. Is that right? Isn't there a risk of the soft corner seal falling in there? What about a risk of the bottom half of a stock 3 piece seal falling in there?



Or are those problems avoided by running solid corners and running the seals with the triangle piece facing this port opening?



Thanks,

Brian

That measurement your talking about is exactly 11 mm. Ill post a picture of the apex seal and corner seal plug traveling through the port opening.

Brian, here this picture will show that the inner peace of the 2mm 3 piece apex seal will be supported by the side housing. The corner seal plug could be removed from the corner seal or use solid corner seals. I prefer solid corners seals since they are stronger and could take some detonation better then the none solid ones. Either way this is the largest streetport available without going into a wild streetport and not exposing the sideseal to the opening of the port itself. This port will be reliable and creat some nice power.

WOW, what size monitor do you have? That port is almost 6 inches wide on my monitor! https://www.nopistons.com/forums/pub...IR#>/bigok.gif
