I'm curious as to why Do88 doesn't already have a plenum available for the 991.2

They will list it soon as it’s now confirmed to fit.
@do88 performance feel free to chime in on anything I may have missed out on.

This post is what convinced me to put the IPD on my 991.2: https://rennlist.com/forums/991/985450-991-2-carrera-ipd-plenum-testing-results.html
My car already had BMC filter, Kline inconel headers, soul sport cats and anti-drone x pipe. I felt a noticeable bump in power in the midrange after the install. Then I had a custom Cobb dynotune to bring it all together. The car is a blast!

Thanks-doesn’t look like that link is working-curious as to what the findings were.

Being completely honest, I am one of the non believers that it will make a difference on a relatively stock/bolt on platform. I plan on dynoing and overlaying some runs in the next few months to see if there are any midrange gains. I will also pull out the dragy and see if there are any differences on the road. For me, it’s an easier pill to swallow being half the price of the others if the gains are not there and I don’t think it will hurt performance in anyway.

I’m in the same boat - I don’t think these plenums will make a noticeable difference (if any at all).
IMO, the biggest bottleneck after the intake inlets is the stock Y-pipe. It’s tiny, crushed, and generally looks to be a poor flowing piece that can be improved on and actually make power gains. Only problem is there’s not much room/clearance to play around.

I took a close look at the y pipes to see if there was any room to work with and can say there is very little if any at all as you still have to fit the intercooler ducts…unless the ducts are modified or remade, I don’t see it happening.

Brand X had an Expensive part that makes dyno proven claims of power. People argue it won’t make that Power and that brand X did their own dyno.
Brand Y makes a cheap copy at half the price, with clearly an inferior design, and it doesn’t make any power.
The wrong conclusion that is drawn, is that Brand X must be lying and theirs must not make any power because the half assed one never made any.
Sorry, it’s faulty logic. I see it all the time with Headers and Exhausts. Brand X has done all the engineering and spent the money to ensure the subtle differences actually contribute and make the item perform.
Almost 4 years ago, the very first mod i bolted to the car was the IPD Plenum. The week before I was at roll racing.
There was a modded RS3 running E85 that every race we were locked door handle to door handle. He was so proud that he ran with a car that was 3 times his price.
I had the IPD bolted on and went back next week.
I pulled on him every time. Before IPD, we were door handle to door handle. After IPD, he was locked to my rear bumper. You can argue about how little difference that is, but a win is better than a dead heat in my book.
About a year after that BGB Motorsport was sick of all the arguing about if it worked or not and dynoed before and after. It was a clear 15hp in the mid range, but up top resumed back to normal power. So it caused a bubble in the middle, but did not add to peak power.
Having had my car dynoed so many times and now up graded turbo’s I know why this happened.
Stock turbo’s fall off a cliff up top. Plenum by itself is not enough to over come this.
Will Brand Y and Z make any power? i don’t know. But if they don’t, is has nothing to do with the fact that brand X does make power.
My other point is, the IPD is most likely the lowest cost mod on my entire car, yet causes the most drama.
When you see the IPD beside the stock plastic piece of crap, your eyes tell you it will help.
Just like the huge mandrel bent TiAL tubes. Way superior to the weasel squashed plastic stock ones. Won’t make you leap tall buildings in a single bound by itself, but eventually there will be a sum of all the parts benefit.
just my .2c.
