IPD Intake Plenum Installed - Dyno Results!

Leo,
I know that you just got your turbo and like me you're looking for every goodie to install on it.. I went down the same path and wasted a lot of money.
After you get the exaust the next GOOD mod is lowering springs. Depending on which brand you get it will lower your car 1 inch to 1/2 inch. The car will look better and handle better. If your still looking for performance you'll want to get a good Tune..There are lots of good ones out there. Do your research. You dont have to get a Softronic tune through Vivid. Dont let them tell you that.
Stay away from plenums, throtttle bodies, bigger Y pipes and headers. Big waste of cash. I know it's tempting but dont do it..
Bigger intercoolers can be good but... If you have the exhaust and a tune your car will be a beast and will have all the power you will need. If you still want to spend money take some track instruction, DE, Autocross events. Money much better spent.
Keep that old airbox around just in case you have issues with the Fabspeed unit.
Welcome to the forum!

Phillip,
I really apretiate your suggestion and I think you are 100/ right! I'm listening to all of you guys that's why I joined the forum because I know you guys have a lot of experience.
Thank you

phillipj,
Can you tell us more about why all those intake (and headers) components are a waste of time... I may have missed it but has anyone ever posted dyno results proving that those components failed to do anything or hurt performance?
Appreciate the words of wisdom... the sales spiels are tempting to believe of course...

In fact most of the vendor claims aren't backed by any real data.

The problem with aftermarket parts is that they are engineered poorly, fit poorly and have very few hours of testing to back up any performance gains. No matter what they say.
They just throw numbers around like "15 hp and 20 lbs of torque". "Our dyno tests show.." What dyno tests? Under what conditions? With what fuel? I had all that Vivid "agency"crap on my car. As well as the IPD stuff. I has so many problems with the poor fitment and other issues that I took it all of and went back to stock. At that point I realized that if there were any performance gains they were so miniscule that I noticed really no difference going back to the stock set up. I felt like an idiot.
Now headers are not a waster of time but...For $5k are headers worth a few hp? You can port and polish your stock manifolds and get great results.
The stock air box is very difficult to improve upon. If you notice the 2011 GT2 RS runs the same box as the 997-1 and 997-2 TT (although the cover is CF.) If the creators of the GT2 RS at Porsche could have improved upon the intake they would have.. They had the budget.
That's my 2 cents.. I f you want more performance run better gas. Give these cars a tune and good exhaust and they are awesome. If you really want more you'll have to upgrade the Turbos and IC's. Which is another slippery slope.
I have friend that is building a 1000 hp 997 TT that will run on pure E 85. We'll see how that turns out... For me I'll stick with the trouble free 550hp I have.
I hope this helps.. Just my experience and opinion.

All I have is the Protomotive (race gas) tune and a Techart exhaust. I also lowered the car with H & R springs and put 15mm spacers on the rear.
At one point I had the plenum, GT3 TB and larger Y pipe. Took it all off and went back to stock.
I also had on the Evoms BRV valves, Took those off too. Might put them back on though.

The problem lies in trying to improve a system that is already designed incredibly well. Although in theory a larger plenum, TB and Y pipe would increase air flow and hence increase HP. But it's not that simple.. Each component has to work together along with the ECU which need hundreds of hours of testing to perfect. Do you really think some little machine shop that make plenums have the same resources for R & D that Porsche does?

You can't really 'mod' it better than stock, personalization, yes.
I think an exhaust n tune and minor suspension mods for adjustability are really all you need.
Don't get sucked in by all this bs. I'd stick with a known tuner like fvd and their 555hp level 2 package...hmmm!

I just got through testing and evaluating the IPD dimpled plenum and y-pipe on my 2011 911 Turbo S: Improved hp, torque and 2mpg better mileage. No question, road and track improvements.
The y-pipe was the biggest surprise: total improvements at low-end of throttle- up to 30mph. Shocking change that made me warn valet parking to "watch it."

IPD
I don't know how to re-post but someone here challenged IPD data. They ended up buying it after IPD put one on a Dyno with exact same circumstances b4 and after and gained a lot of Hp. Not hype at all about their plenum.

^^^I read that thread on 6speed. Don't know what too believe. . As a engineer I understand their design improvements promote laminar flow by reducing turbulence in the "plumbing", but the power gains with just the plenum seem almost too good to believe
