Porting Templates
No plans at this time for 13B-RE Cosmo porting templates. Perhaps if something comes through the shop, we could make templates from that job, but most of our jobs are so specific that we would not want to use them as a basis for a template. Unless you had the identical setup, the port timing and size may not suit your application. Also, we do a lot of asymetrical porting (different porting for each rotor) to balance flow for a specific manifold.
The templates at the CNC shop will take a week or two. I try not to rush vendors because we get better pricing letting them do it as fill work and when I am in a rush, they will know it's important and hopefully step it up. At least I am now dealing with someone at the shop that seems organized and on top of the jobs. The other person I was dealing with was the owner, but he was a bit scatterbrained and mixed up jobs all the time. The work they do, however, is first rate and very affordable, so it's worth the hassle.
I would be happy to hear any schemes for locating the exhaust porting templates, but I think I have a solution myself. There are any number of ways to locate it within a couple milimeters, but I want much better precision.
Once I have the exhaust porting templates, I plan to offer a complete kit. This would be the intake and exhaust templates, a small bottle of layout fluid, a scribe and basic instructions. We may also do a porting video to sell as a DVD.

I just sent the CNC laser cutting shop the "medium" streetport 13B-REW file. It affects the size of the primaries more than the secondaries, but they are both bigger. This is about as big of an -REW streetport template I am likely to ever sell, because things get tricky if you go much farther and the people who know how to deal with that are capable of determining their own port timing. You can always modify the template with a die grinder if you want the consistency of using a template for your large streetport.
Nice!!!

I have both sets of irons in my garage, and they are very similar apart from the port runners on the re being much much larger (they look like they are as large as they possibly could be).
the secondairy port opening on the re is bigger, but the primary is smaller.
I have to go back on what I originaly said here, this is not true, I just made construction paper templates of the rew ports to compare to the re, the secondairy port openings are identicle, in position size and shape, the re runners are much larger at the opening, but they taper down to the port. The rew primaries are significanly larger and shaped differently. They close about the same time, but the rew's open much sooner.
So back to the original question, is there any good reason rew templates won't work on an re?

The CNC laser cutting shop just called. All of our intake templates are done. 13B-T, 13B-6PI and 13B-REW medium streetports. I will go pick them up tomorrow and do the final cleanup (deburring, polishing), then add them to the web store.
Blake,
Are the 13B medium streetports the largest port you will template for the FD motor? If you can post a pic against a stock port as you did for the small street port, that would be great.
Thanks,
Anthony

The intake templates are here, in my hands. Everything looks great. I am pealing the protective coatings off, deburring them and taking photos this afternoon. I may have them on the web site this evening, if time permits.
Here are the photos of the new templates. As requested, I did a closeup of the -REW medium streetport over a stock port with a scribed small streetport. The 13B-6PI template is easy to identify due to the auxiliary ports, but the 13B-T looks a lot like the -REW plates. The etching in this batch is very light, due to the power level they used on the laser and the protective coating over the parts. You can see it better in the refelction than straight-on.

Also, "agressive" is not a word I care for with regards to porting. It implies that larger is better. A smaller port, better designed will outperform a larger, poorly designed port. Also, different timing specs are good for different purposes. We have done streetports that put down better power than most bridgeports. If you know what you are doing, you can do more with less and make fewer compromises. Just keep in mind that the port outline is just a fraction of the formula. All the "magic" happens in the bowl and runner of the port.

I wasn't using "aggressive" to define "bigger"; but rather a higher volumetric flow. Agressive would define how fast it pulls money out of my wallet at each fill up.
Blake, instead of camparison to a different company could we just get a look at the 6pi compared to a stock port, like that layover you did with that 4 port one? I deffinatly will be getting a set in the near future.
