It uses the same supercharger as the Cosworth if I have heard the model numbers correctly from each manufacturer. It's up to personal opinion. Same thing on PD SC vs centrifugal SC vs turbo. All different. The powerbands are different and they will perform differently. And at some tracks, the car with more midrange will perform better by possibly eliminating a shift and enabling a higher gear through a turn, whereas maybe the straight away is long enough that the super laggy turbo can make up for it with sheer HP.
While it may be true about OE work for this platform, they did tear down the engine to do finite analysis of each part and determine what can be achieved at each level and where the weaknesses lie.
It's good speaking with you gentleman about this topic. I am not afraid to admit when I am wrong at all. I try not to speak about topics I am not familiar with. I have just been very intrigued and really enjoy the supercharger comments. I have had a special place for the Cosworth brand from their participation in other motorsports so I really like following their developments. Just like how grimmspeed has a lot of information and engineering. It is fun to see developments. I also have some Cossie pistons in my vehicle, so I am slightly biased.
And that is why i understand the skepticism. That aligns with why I was frustrated and stopped being a lurker. It was the statement that you would not want to do track days because it is heat soaked. The same way that there is not data supporting it is a track focused supercharger should also go the other way saying there is nothing supporting the opposite.
Have a good one.

- CARB certification (was told "months; been 9 months now)
- Track testing results publication (non published)
- "further development, higher boost, engine internals" (none has happened that has been released, that I am aware of)
Cosworth does indeed have quite a legacy, but past performance is no guarantee of future results. The last truly groundbreaking car I see from them was the Escort Cosworth; that thing was a monster.
Look at Honda for example; they make some of the best production car engines, but are failing miserably at F1 powertrains. Likewise, I doubt Cosworth's Indy/F1 engineers are working on the FA20 supercharger project, and vice versa.
As I've said before, I'd love to see a truly developed Cosworth product on the market; competition is great for the consumer, but other than their initial supercharger release, nothing else has actually been released.
