Porsche 986/987 IPD intake modifications to improve the poor design. (Boxster/Cayman)
The IPD intake Plenum is the best way to add the larger throttle body from the 911. However, previous testing has shown it has minimal benefit, if any, for torque and HP (th-cam.com/video/zRUHnGPJC0Q/w-d-xo.html). There are several engineering shortcomings to the IPD design, and we make several modifications to improve the performance.
Stay tuned, and dyno testing will be performed later this year.

Porsche 986 Boxster S Air Intake Modification Results from Dyno (Fabspeed + IPD)
มุมมอง 7K2 ปีที่แล้ว
We take a closer look at the installation and dyno results of the FabSpeed air intake, the IPD plenum and the oversized throttle body. Results were mixed, and did not achieve the desired gains as outlined from the manufacturers. The baseline car does have an aftermarket Fabspeed exhaust that added 25Hp in prior testing.

So, did it work? I have similar issue on Honda AL block
Youre a legend.
Great Review! May I ask if you have any other physical mods installed except for the exhaust (I know that there's an ECU tune)?
Great video. I reckon the boffins at Porsche might have got it right first time. We all love a bit more power, and as far as intakes go, you were very thorough. Now if some of those clowns that rip out their intakes could do their homework before posting BS on youtube, it might save some gullible enthusiasts from wrecking their cars. Moral of the story... get an expert's advice before you make things worse.
Nice video! Question did it work?
I've got a 2004 Toyota Sienna that has a hole in the (6 cyl, aluminum) block a few inches from the oil pump, due to someone putting too long of a bolt through the AC compressor attachment bracket. Finally got the oil leak diagnosed today. The bolt had pushed a flap of the wall of an oil tube on the block inward a couple of mm. The shop is going to see whether or not a welder will quote to repair the hole with the engine in place (after removing the radiator and a bunch of other stuff to give him access). If not, or if the overall quote is too much for me to stomach after all the other money I've thrown at this vehicle in the past year, then we are looking at a temporizing measure like JB Weld. Thoughts? If I end up going the JB Weld route, am I looking at living with an oil leak, or re-doing the JB Weld every couple of years, or what? Thanks.
Hi Mike, do you have any updates on this? I have a track day coming up and Id like to see your results as I too get smoke in hard turns. Thanks!
How did it work out? Would you still recommend doing this the same way? I took my Boxster S to the track and it spewed Pentosin out of the PS vent on top of the motor.
It works great. I run her, sticky slick track tires, and I am a track driving instructor, so I probably do almost 1000 labs a year. Have never had an overheating issue of the PS fluid.
A year later. I wonder if they made a change. Anyway, your choice of the word "significant" isn't all that quantitative. Keep in mind, a partly closed window won't let as much wind blow through as a completely open one. As far as a company, they are very self-promoting. Probably to try to justify their exorbitant prices. Silly as other aftermarket companies arn't so aggressive, still sell parts, and their prices are way too high as well (as it's Porsche).
Well summarized. As a recovering engineer, I wish I could give you harder numbers to make it more quantitative. But given the net gaps in the design, the engine would move a significant amount of warm idle under G-Force changes.
What about the ‚W‘ at the beginning?
How was the weld ? What kind of marine weld u used ?
The world lasted several years. I have since sold the car. I used marine JB Weld. I believe there is only one variety o this product.
Nice repair - But I think the Huhn solutions insert - which is considerably longer than the time-sert insert - caused this crack. A longer insert goes deeper into a thinner part of the engine block. This likely would not have happened with a time-sert.
You may be correct, but the time CERT inserts have a problem of pull out for Weik blocks. If they pull out, now, you are going to a secondary re-tapping process that has its own list of issues.
I rarely write anything in comments section, but this video was done very well. Found it very informative and well planned out. Great job to the author(s) of this video! Learned a lot!
Glad it was helpful!
the most comprehensive non manufacturer’s video on this type of subject you’ll ever find. Well done
Thank you Robert!!!
The only “jb marine weld” I could find was in a syringe “white” color but yours is a dark gray, ive got a coolant leakage from the side of an cast aluminum cylinder head on a gm ls engine. Would this be ok? I’m planning on letting it sit for a week
Mine was not in a syringe. www.amazon.com/J-B-Weld-8272-MarineWeld-Marine/dp/B000KKPFFA/ref=sr_1_3_pp
It the jb weld hold up through the time ?
I sold the car 1 year ago, but it held up as long as I owned it.
Did you get power steering line issues? I’m going to get the full exhaust parts upgrade from ebay. Gonna get them wrapped before putting them all at once.
I added a P/S line cooler. There is another video on my site showing how to do it. Good luck!
Did you install the accusump setup yourself or have a shop do it? If you had a shop do it do you mind sharing with me the labor to install the accusump?
I installed it myself in the location of the current fuel filter. I move the fuel filter to under the hood, next the battery.
The poor oem design is superior to this thing because the wave of intake must bounce of each others bank to help fill the cylinders. This was very popular 10 years ago but no one had any positive dyno test with them.
I agree with you nine times out of 10, but Porsche also wanted to keep the Boxster in a lower performance category than the 911. As such, there are ways to open up the breathing capability of the engine, and extract more performance.
ANYTHING by IPD is crap....why are you even bothering with this nonsense!!
It is the easiest way to install the larger throttle body.
Great series of videos. I have an 02 S [same color, too] on which the previous owner had installed a full Fabspeed exhaust and tune, and I was considering the ipd plenum as well. now I’ lol spend the money on something else.
Good luck! Fun car ;-)
did gasket on Peugeot KFW engine, now coolant weeping from 3 spots on the block!
Is there a question in here? Sorry...
no I was saying I replaced the gasket but the block weeps (engine was overheated) car still working, just needs coolant every week, would be impossible to weld the block as the holes are invisible@@mikepetersen3
why didn't you just buy a 996 plastic plenum off of E-bay for $65 ? cheaper way to mount your 996 throttle body
In hindsight, I would.
So is the IPD plenum a scam or not? I just put one on my car, with the GT3 throttle body. Still working out some bugs (CEL).
Did you solve the cel if so how?
@@captainbuzcrust7415 I did. My shop used GIAC for the ECU tune. Working with GIAC, it was determined that there was a line of code that should have been deleted for my setup. I can’t recall the exact detail, but I think it had something to do with the fact that the ECU was seeing more air than it thought it should be seeing and threw a code as a result. Well, the “more air” was a feature, not a bug, so that line of code was removed. (I *think* that’s what the issue was.) The shop had to eat the cost of the second re-flash of the ECU, since it was an error on their part (they probably worked something out with GIAC). No more CEL.
IMO, opinion, the most value of the IPD is to upsize the throttle body, but you can also use a 911 plenum to do the same thing. .
I'm wondering if you went to E-bay bought a $60 OEM 996 plenum to mount your 74mm throttle body and ran it on the dyno to see the difference from an OEM plenum and the IPD plenum would it be the same or better than the IPD
The only downside of the 996 plenum is what inlet tube to use. Im sure there is a solution out there, but I have not looked for it.
😉😉
Have you dynoed it yet?
It's on my list of thing to do!
awesome content ; keep sharing please
Sorry, have been so busy, not enough time ;-(
Very well organized comparison between the two systems. Thank you for sharing the thoughts
My pleasure!
Update this dude ruined his shit that’s why no update from himself
Interesting review. Thanks. We’re planning to install an accusump on our 98 boxster and not sure if a deep sump kit is also needed. Still researching ….
They both have pros and cons. no easy answer on this one...
Interesting, update would be great
Sorry, have been so busy, much less time for this. Unfortunately!
We need more updates
Sorry, this is still on my to do list to bring the car to the dynamometer. I had good intentions last summer, but my ear was busier than I wanted.
@@mikepetersen3 Hi! some progress on the boxster?
The exact same thing happened to my M54 engine. Maybe it isn't a good idea to put inserts in this motor? BTW my engine has never overheated, I've owned it since new.
Thanks for pointing this out. I assume my crack was due to the overheat, but it may be a week point in the block for all engines, even those that have never experienced high temps.
You need to have a dropped center (50 mm) in the oil pan and sloped from the sides to the dropped center. The original baffle design needs to be utilized with a 50 mm vertical dimensional increase along with better oil return from the heads to the pan. These modifications will work to address flaws and the oil starvation problems this engine suffers from. Electric scavenge pump system would be the easiest way to get the oil back from the heads to the oil pan.
All very good points. If Porsche would have included a true dry some lubrication, not messed up the IMS bearing, and not giving it fried egg headlights, I'm convinced these vehicles would be worth to 2X what they are today.
No matter how many videos come out of ipd products sucking people just can’t let it be that Porsche engineers know more than them snake oil guys over at ipd 😫😟😫
There are still many ways to improve the engine, it's just the IPD is not one of them.
MaxSpeed makes a cheaper version but truth be told both companies have robbed Porsche owners since day one. Only benefit is it allows for running the larger 82mm tb and tubing. I’m amazed that ipd is still in business
Does the 82mm fit and work on a 2.7 986? Just looking into things and want most bang for my buck but bigger isn't always better
@@captainbuzcrust7415 yes
Hey friend, just did this to my transmission case. However, I did not drill any holes. How bad did I mess up? Wish I would have looked for this video before doing it. Great video production.
The holes prevent further cracking. However, your stress fracture may be at a point where no further cracking will happen irregardless of the holes. I wouldn’t lose any sleep over it, just keep an eye on it. Worst case, if it starts to leak, you can always redo the repair.
Just seeing this video after thinking I want to track the car just a few times a year. If one does not use a deep sump are you destined for damage on your first few track days ? Is there a kit or porsche solution you do reccomend ?
The problem becomes more pronounced with higher G loads. Track tires, lowered suspension, etc. will all compound the issue. If you are running street tires and only doing one or two days per year you should be fine. However, if you want to sleep better at night the deep sump is the best insurance policy
To be fair, I add a whole 150 lb passenger to my car and got maybe 0.5 seconds added to my 60 second laptimes in autocross (where weight and handling are extremely important). Adding weight to the back is worse than adding it to the center, but a few lbs is probably countered by the addition of 1 horsepower. Any more than that is purely positive gains. Edit: I hadn't watched the whole video yet when I made the comment, but that power loss is rough. Maybe a tune is needed to fully take advantage of that intake.
There is a longer discussion above, but I can assure you that the loss of horsepower down low is not a tune in issue. Is this car is designed for track use, I’m less concerned about low rpm performance. And the modest gains above 4000 RPM still make the solution livable.
Can i do the same to stop coolant leaking from my engine block? I am planning to use JB steelstick though
it should work as long as the oil is not coming from a high pressure zone, i.e near an oil feed channel
@Mike Petersen Oil isn't coming out. But unfortunately, steel stick didn't hold. Coolant still drips.
A second thank you for producing... having watched your air intake + exhaust videos, which are both well documented & detailed, I am now confident and clear about how to prioritise our budgeted dollars on a new project 986 S we are kicking off (new intake? no; upgrade exhaust? yes!)
Thanks for the kuddos!
thank you for producing the video... incredibly helpful and well done !
Thank you!
There is less resistance to the flow of air with laminar flow vs turbulent flow. Anything that increases turbulence increases flow resistance. Resistance is a function of gas viscosity and the diameter of the tube to the fourth power. Frank
You are correct.
How is this holding up so far?
Still holding
I just asked a dealer if I might fix a leak on the oil pump cover on my Yamaha R1 with JP Weld. It seems my bike has been leaking out of that cover and into the belly pan after an accident which scraped down the edge and one of the screws which secures it to the gasket. The dealer said: "JB Weld? That NEVER works - I've seen it a THOUSAND times." Which I interpreted as meaning it probably will work. Aka "stealerships". So thank you for this video.
I don’t think JB is a miracle fix, but it’s worth a shot. Depending on the damage you may want to use RTV as the base and add JB on top after it has cured.

POOm???? Help?
Fix your engine with glue ha ha.
Next time you need help, I hope nobody offers you creative ideas to fix your problem.
Going catch can route? Intrigued what youre doin in place of the aos delete
Keep the AOS. It will self drain into the block. But remove the main 3/4” vacuum line to the air intake and cap the intake port.
@@mikepetersen3 can you explain the reason and benefit of doing this? I am rebuilding an m96.21 and deleted the secondary air system
Don’t do it.
So how would you suggest to fix the crack that leaks oil as it’s near an oil passage line?
@@mikepetersen3 he would hire it out. You would do it the good old fashioned way which works just fine! Well done sir
