As I said, the DSM crowd used the standard 16g style 7cm housings on 20g, Frank series, Green, and Red (some Reds used 8cm housings) for a looong time before the vendors saw enough demand for a custom casting.

I don't think it'll take as long in the EVO world, there's already a built in market for big power turbos that'll bolt on, but the question is how many? Let's say a Red style turbo with a custom cast bolt-on housing costs $2299 (assuming $500 over what the Red costs for the cast housing), you're getting nearer to what a T3 style kit costs. As for something to use on a stock turbo, there's already the 10.5 hotside, which is probably about the point of diminishing returns for a 16g wheel. If a custom hotside cost $500, I'd sooner put that money into a BBK lite or FPWhite conversion.

I think if FP were to chime in, they wouldn't offer anything in terms of what they're working on anyway. If they already have a project like this in the works, the last thing they want is to have a new thread every day bashing FP for taking too long. They also wouldn't want their competitors to find out what they're up to.

We added a CNC mill stage to the process where it goes in and adds a big long smooth outlet instead of that little ridge, about 50% of the outlet is now CNC machined in a long smooth radius in the CNC mill. So even the non ported ones are partially CNC ported.

We also now offer a full ported housing option that is more than the early "gasket match" job we offered in the begining, there are pics of it here:

On the topic of larger turbine housings from MHI, there are not any larger than the 10.5cm2 . MHI made 9.0, 9.8 and 10.5 only, then they stopped making the car so MHI stopped making parts

Anyhow, with the red (or even green) there really isn't a real reason to go higher than 10.5cm² with porting. But if your running the stock turbo and your trying to pick up the HP there certainly is.

And beautiful as well! Is that the $100 port job listed as an option for the FP RED, or a more expensive service?

I'll bet that transient response would be extremely good. And it should spoolup quicker than the Red with a lot less backpressure than the Green.
