I'll be disappointed if it is not nicely higher than the 997TTS' 530hp.

I'm happy with my 997.1 TT. No new TT for me until they decide to go for the Flat-8 TT with a more aggressive body.

Dual stage turbos are more for achieving flatter torque curves and better response. It makes a lot of sense achieving big power goals while getting NA like response.

lets imagine the possibilities of a triple turbo gt2 rs... 3000lbs.
a billet k16 for low end. two gt35's for high end.

i would imagine quarter miles in the 9s

I think a tuner or Porsche could set up a car with twin-959 two-stage turbo's, with four turbo's total, running a smaller turbo in series with a larger turbo ala the 959 but with a pair on each side in parallel.

Expensive, but, using appropriate hardware components, manageable.

Why can't they just put in a pair of Tial Alpha 3076s and make 10 the loudest?

I don't care how many turbos are on it, did they do anything to strengthen the engine internally?

Hey, somebody gets it!

I don't see a need for three... But two sequential turbos has every right to exist. I dislike the -more is better- mantra (unless we are talking about American products).

I mean, a few reasons for twin turbos is to allow for smaller turbos, quicker spool, etc...

With bigger turbos, it takes a few seconds to get up to speed, so the smaller turbo would compensate for that.

(Reminds me of the quad-charged GT-R... just don't need it)
