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.
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.
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.
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!
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
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.
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?
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.
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.
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
@@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.
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
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 ….
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 😫😟😫
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
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.
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!)
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
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.
