Let me make this real simple...25rwhp on K16/24 turbos. That's what it's good for. Dyno verified before and after the mod.

pca911turbo is infamous around these parts

And all you did was let the car breath a little better. No other modifications needed. But how could you increase TQ/HP by other mods and not do this one?

A "T" shape is the most restrictive shape for any fluid dynamic flow. I have taken fluid dynamics in college and it is my understanding that curved will produce more TQ. Maybe that is why Porsche went with that design this time around!

OK my confusion...I thought you were talking about the "T" shaped when you were talkng about straight (as that is what is stock on a 996TT)...my bad. I am still a little confused because the part that is being referenced in the thread is an aftermarket intake (curved) not a Porsche part...or are you saying the new turbos have the curved intake?
