Cosworth Power Package/Parts Teased

Lots of people don't need another belly button though

Guesses? I'm saying this PD blower setup alone is 9-10k as a guess.

There is such a blower. It's called the Eaton TVS900. Same displacement as the Sprintex, but it revs 26.7% higher and thus flows more air than the Sprintex 210. It's also just as efficient, but with larger efficiency islands so it will ultimately run a little cooler. Judging by Cosworth's advertised horsepower numbers, I'd say that is the blower they are going to use since the calculations I did for the TVS900 were spot on with those numbers. For me, it's bittersweet, because that's exactly what I wanted to do: same mounting location and all. I just haven't had the funds to do it.

What would be interesting is if they use the standard Eaton case. If so, there would be some additional room for improvement with a better case design to get better VE across the board along with higher adiabatic efficiency. Even with the standard Eaton case, it should beat the snot out of the Sprintex blower up top while matching it nicely in the low end and midrange torque.

Also, from everything I've seen, the Sprintex supercharger kit has what looks to be an extremely restrictive intercooler setup. A more conventional heat exchanger would have less pressure drop across the intercooler core without much of a sacrifice in heat exchanger effectiveness. In fact, for the same pressure drop, a conventional exchanger design would be more effective than the Laminova setup Sprintex is using.

I have a feeling the Cosworth setup will perform well...pricing on the other hand will just have to be a "wait and see".

Good info and after looking into this abit more I don't think you're far off at all on your assumption. Wait and see yes we will indeed.

whats wrong with the standard Eaton case?
You'd think that Eaton with all their resource would have this pretty well developed?

From a strictly manufacturing perspective, there is nothing wrong with the case. From a performance perspective, however, there is much more that can be done to increase the VE and adiabatic efficiency. Eaton, like every company on the planet is in the business to make money and the law of diminishing returns makes it such that further increases in performance result in substantially higher costs to manufacture. The bottom line is that if you want more performance than the standard Eaton case provides, you gotta pay to play.

What sort of mods then? would they need a new case or could they be done with inserts and the like?

I'm presuming your talking about a less sudden expansion of area out of the blower exit?

If they come out a NA 250WHP package, it will be more interesting for my car

Well it's a nice dream, and if remotely close I'll bet ya that would be double the cost of what a Turbo that would give you 350 would cost.

I know fi is easy to get horses, but I am not a fan of fi, so I rather do na mod

Cool well as long as your wallet is "Cosworth" fat you'll be golden.

[Ruckus]

Nameless and cosworth ftw

[Panda Mao]

i'd luv to see them make a intake manifold for our cars or even only possible....individual throttle bodies on a flat 4 motor I can only dream.....

This is what goes on inside my head every single day as I decide what to do with my BRZ.

I'd love to get 250 NA.
