Looking to upgrade intake for Panamera Turbo.

If talking about iPD Plenum i cannot see big difference between stock Y plenum and iPD. The configuration is very similar comparing to 911 models (where iPD offering Y-pipe instead of stock T-pipe)

Agency Power carbon Y-Pipe is 3" inches however it is not 3" from the beginning of pipes. Also i'm worry about the engine movement because carbon intake much harder than stock and can be cracked.

What is you experience? Please advice.

 

You should buy the turbo S manifold , its really worth because It has more top end! And its only 850-950$ new in box . Also for the price the y-pipe arent worth wright now but later yes ! Like Renaissancemen showed us on the cayenne forum , in whicg the stock y-pipe is very restrictive .

 

Do you have part numbers for Turbo S manifold and other things which need to be changed at the same time?
I already found that Turbo S has different intercoolers too (part number: 97011020961, 97011021061)

 

Turbo S have bigger intercooler ? Strange ... pm about the part

 

What do you mean not worth it now but worth it later?

 

I know Nick outside 6speed .. it wasnt worth at the time because of 3 months time to be costum made from agency . And 1.5K for an y-pipe vs 4k for bigger turbocharger set from fvd , well no matter how much you increase the diameter of tubes they wont produce like new turbochargers .

 

When you change to turbo s manifold with throttle body 82mm, will agency power y-pipe fit 82 throttle body? Also do you need a new MAF sensor from the new 82 mm stock plenum.

 

where to find the Turbo S manifold ? how much ? and , will improve approx how many HP ?

 

Suncoast parts will have/procure a manifold.

 

Porsche part number for X80 Power kit Manifold - 94811001675

I already installed it.

 

Any pre and post-install dyno or VBOX tests?

 

I have FVD tuning for next parts: Manifold, BMC filter, Supersprint downpipes+x-pipe+PSE Exhaust mufflers, AP diverters. Haven't any dyno tests yet and it's not important for me, 'cos it's always better to know how to car really goes on a road (thanks to Racelogic) instead of clear dyno numbers (which maybe very different from one dyno stand to another)

0-100km/h 3.1-3.2sec
100-200km/h 7.3sec

98 octane, +12C. Stable results.

Btw, i just setup Supersprint HJS 200cell cats. 100-200 was drop to 7.6sec. (but on winter tires)

 

You lost me there, with SS Downpipes your time dropped to 7.3 or went up to 7.6?

 

I wrote that it's dropped to 7.6sec after installing HJS sport cats 200cell because the result is worse(!) than with SS downpipes (which is 7.3sec).
Different words - with downpipes car goes faster for 0.3sec on 100-200km/h.

However, i like the mid. rpm range more on HJS cats. I assume that backpressure playing important role in it give the feel that car goes smoothly (less turbo lag?).

 

SS downpipes? Downpipes either with or without CATS. You're saying cat-less you gained .3 sec.... Turbo cars dont need the back-pressure and as such a cat-less setup on any boosted application will remove restriction and always yield gains.
