a friend paid me to port streetport his FC irons. the center iron is actually from an NA i believe, so the primary ports started out pretty damn small, as you'll see in the pics.

we have to re-do the front secondary because i went a little too far down on the closing side and ended up doing a custom water injection mod :x

i know they're not the best pics, but let me know what you guys think.

 

Wow everything looks great, all transistions and the finish looks very smooth

Anyphoto of the botched secondary? just curious where you ran into the waterjacket

 

yeah i'll post some of the custom water injection mod here in a second. lol


it looks like i didn't really post any pics straight on of the port openings, which are important. i'll post some pics of those in a second as well. also, i made the opening edge a little larger larger than the template.

 

I like the soup can idea

 

here's the custom water injection mishap


better view of the secondary opening


better view of primary opening




it's kinda hard to see, but i added a .5mm bevel all the way around the port openings (more visible in the pic of the primary)
you can see in the shot of the secondary that i made the opening edge a little fatter than the template.

what do you guys think?

 

looks good.

don't feel bad. i punched through my first couple of Gen II housings when i first started, too.

 

.

 

hmm. no other thoughts/suggestions?

 

They look pretty good from the pics...those primaries look awfully big though, how far outwards (towards the water jacket) did you port? The bevel is only needed at the top/closing edge of the port. How long did it take you? Seems like you spent some time on it

Custom water injection mod looks nice lol.

These are for me btw.

 

Good choice on the white cheddar cheez it, except for the reduced fat taste horrible compared to the regular ones.

Porting looks good

 

How hard was that?

 

sorry i forgot to check this thread for a while.


i only went about 2mm out towards the water jacket. if you're talking about the secondaries, i agree, the ports are pretty fat, but there should be plenty of room for the corner seal. there's about 5mm between the outside edge of the port and the mark where the corner seal rides.


also, i'm about done with the new iron, and i'll be doing the housings tomorrow.

 

try to keep your lines (radius) as consistent as possible. focus more on the inside of the ports(runners) then anything else. tro to get a smooth transition into the closing edge of the port.(upper part) adjust your style of porting, according to the engines particular needs. drag,drift, road race.. etc.etc. bigger is not always better according to the applicaton and goals for a particular engine. here is a cell phone pic of a port I did recently. here you will see consistent lines(radius) across the port.

 

i think all in all, you did a giid job. would like to see the updated pics.

 

looks good as always ito!
