Any more info on this Kelly? Are the ports machined oval-to-round like the JGS flange? Who should I email direct for more info?

I am looking to buy a nicer-than-ETD flange for my next manifold. I've emailed a few places but received no replies I figured I'd have to make my own but would rather not if there's another source!

I bought the last 2 flanges rob (flipside) had for the 1.6, i think. They are SS and look like the etd ones except one side has circle machined into it so that the weld els recess into the flange. The outlet itself is still oval though. They are a little thin, but I will just make sure to do the runner to flange welding in bursts to not let it overheat.

Here's my $.02 on turbo manifolds from what I've read and experienced with my own car. With tubular designs short runners seem to give quicker spool since the total manifold volume is lower. Each pulse is also directed to the turbo inlet vs. log style manifolds. I can't imagine there's any scavenging effect at all on turbo manifolds because of the back pressure. Long runners don't help. If anything they hurt spool because the total volume is greater. The runner diameter doesn't need to be larger then the port. If it were, the velocity would drop when the flow hits the larger diameter. On the other hand, if the runner was smaller, the velocity would be increased but that creates a restriction at the port. My DIY manifold I made for my first setup was a log style and I was very suprised at how well it actually worked. The exhaust pulse had no direction what so ever. It just fired into a tank then had to find it's way to the turbo. I'm running a tubular manifold now that looks like the ssautochrome one. I'd say spool-up took a hit but it flows alot better at high rpm. With the log style running 10psi I could feel the torque dropping off as I approched redline. With the tubular it pulls hard well into redline. If I came across a deal on a shorty tubular manifold I'd jump on it and replace the one I have now. Those are the best choice imo and even Bell and FMs manifolds look like short tubular ones just made of cast iron. My recomendation:

-Keep the manifold's total volume as low as you can.
-Keep the ports seperated. (don't let one fire into another)
-Keeps the pulses directed towards the turbo's inlet.
-Use a large downpipe/exhaust and eliminate any restrictions after the turbo.

I believe all those Vibrant collectors are designed to fit a T3 inlet. I could be wrong though. I played with them at a trade show last year. They are schedule 10; they said they had plans to work on Schedule 40's but I have no idea how true that is.
