So I have the Judge Ito porting templates (aggressive streetport) and I'm about to finish op 2 sets of irons with it (one set of used irons, one set brand new)
the porting goes quite wel but I'm a bit in the middle about how to finish up/clean up the port opening and closing edges. The original ports have been CNC machined and the angle of the iron surface to port is about 90° with a cut-edge. I can imagine this is quite hard on the side seal, eventhough the side seal still has a large area which is supported. So the question is... is it smart to try and get the extended port edges a sharp as possible or better to smooth it a little for easier transistion of the side seal from port opening to iron surface thx Neal |
"better to smooth it a little for easier transistion of the side seal from port opening to iron surface"
I like to smooth it and add a 1mm long, 45° bevel where the side seal rides. |
Excellent info, many thanks

The closing line should be radiused slightly, and polished like chrome. If you ran your tongue over that port at 100 MPH would you want the closing line sharp or radiused? All of the side seals vote for radiused. Lynn E. Hanover |

How about from the Man himself (Judge ITO) Hy Grizzly, Nice to see you're still around. How did your port job turn out? You have these templates as well, no? |

Yep i have the Template, i've used it twice now and i've not had any problems with it. I had a bit of a Crossed wire or two when i was reading up how to use it (well how the end product should look) but apart from that every thing is Good. Did you end up finishing yours? I noticed you had some of the Parts for sale a Bit back? Yeah I did, I ended up having 2 parts engines and although they were fine and perfectly rebyuildable, I chose to go for new housings and irons; I got them for a great deal so there you have it. I will be rebuilding one of my spare engines for a friend with thesame porting and have a big part of my costs refunded. Tomorrow I will have my drivers to press and install the rotor and stat gear bearings, then I'll do the port job again and finally rebuilding the engine. How are you running your engine? Seq, non-seq or single turbo? What else did you mod and how does then engine compare to the stock one in your opinion? Many thanks Neal |
