my Boxster has had these mods on the car for two years, stainless steel headers, K&N filter, running a 996 74mm throttle body and plenum, large intake pipe from airbox to throttle body, de- snorkeled and bypass mod done to stock exhaust, finally a standard flash for the ECU :) love it
MAF tube and intake manifold are the limitation on the 3.2. and headers of course. If you're moving enough air to start maxing the OEM ECUs ability you'll have issues with MAF scale and the larger TB. MAF tube is in front of the TB... You'll start hitting the max airflow if you're doing everything else right. These motors should make 305-315 at the tires when full bolt on... And they don't... Which means most people are missing the key components of intake manifold and MAF tube. Which I know why, it gets difficult to make changes on the ME 5.x to change MAF tube size... Solution? Run a factory 996 3.4 ROW flash. It will make another 20-30 HP over even a tuned 986S file.
Agreed. My 2.5 is 2.9 making 305 with my mods. Kicked in vario cams early at 4600. Those VR tunes are garbage cookie cutter. Open them up in Win OLS they look like a child did the checksum.
@@HORUS9yessir especially a 3.2 986. However the later 986 has a different ECU, so I don't know about tuning/ECU limitations as much. As far as I now for all M96 though, 3.2 intake MANIFOLD/exhaust is total crap, and MAF tube is tiny. Most people only address exhaust and airbox. The throttle body/plenum are between two bottlenecks, doesn't do crap. The car I'm referencing is a 3.2 turned 3.8. Ran ok but factory tune put down 272, which is right on the edge of what any bolt on 986 will ever make. Where as a 3.4 with bolt ons (not including the nice pistons/bottom end in the 3.8) will make over 300. So either go standalone and ditch the MAF tube on speed density, or use a 3.4 ROW ROM as a start and use the larger MAF tube (get a straight one from a BMW with the honeycomb collimator to fit the MAF sensor. I think they're off a 540i or something. Also I think 911 runs slightly* higher base pressure
It has been constantly proven that the IDP plenum does almost nothing to increase hp. It’s just a shiny piece of aluminum that’s is nice to look at. It is laughable to pay $700 for a 2-4hp gain. Good content tho!
So m97? I don't know if the chain guides are any different to the m96. Cam chain guides wear and break so early on these. Pushing further than 7 would in my mind break them sooner. This will cause cam deviation. You didn't show the graph or mention when power drops off. 2 cents from an ol fart that has the 2001s. Great video. Thanks
@@ipstuned service is one thing but leaks from cracked 20yo plastic and crusty O rings is another. It would be good content for the channel if nothing else
Nice to see actual dyno results. Great vid man keep em coming
Appreciate it!

What is your standart flash? I have the same mod list.
112 degrees!! OMG
Wth what you doing here!
You should include a parts list with links, and a running tally of what the modifications have cost for the whole project.
Also, how much was the HP increased after the install of the parts but before the tuning?
@@bleibow I am curious if I can do this modifications without tuning the 986.
@@jeremyocampo1529 yes. You can, the ecu will compensate for the extra air flow
@@eblevinda okay thanks. I’m planning to just doing some bolt ons like bigger Inter throttle, better exhaust, etc.
This is awesome dude you’re killin it!!! Keep going
Boxster is a great car. I hope one day I will buy one.
Maybe you could overlap the graphs and pause for a second or have a table with the power from each mod

Would you need a 996 3.4 VIN to do that?
+Hi Friend, Can the same advice be applied to a 2005 boxster s with the 3.2?

Torque gains are nice
Great work
Screamer!!

Good content tho!
Cool video’s, nice job you have. 👍🏽
+30hp is not bad
I also want to make a boxster track car thanks for the video it helped me a lot !!
That is awesome thanks for letting me know!!
Good luck with your project!
@@ipstuned thanks man but I have to buy the car first 😂

Great video. Thanks
Where is your shop located. Great video.
We need some driving clips
Any chance you can help me with a parts list or where I can get the intake tube?
Can the same mods be applied to a 2005 987.1 Boxster S with sport chrono? Does having the 987.1 or sport chrono change the process significantly?
Is it actually 250 hp to the wheels as in 294hp at the engine?
Are you going to smoke test for vacuum leaks? Mine had dozens from old cracked plastic and rubber. I’m betting yours does too
Engine was service before buying it
@@ipstuned service is one thing but leaks from cracked 20yo plastic and crusty O rings is another. It would be good content for the channel if nothing else
didn't it make 249 in the last video as well?
I thought he said, "239 hp."
I have a 1999 BOXSTER not the s can this be done to my car ?
Yes it can be done ! The power output won’t be the same but the gains should be similar
Are you located in texas?
@@ipstuned no I’m not but just wondering if this can be done with a BOXSTER not the s
Ok thank you sir 🤟🏽👍
I own a 2.7 boxster. All the bolt on parts are the same as the 3.2 only the 2.5 has different headers
Where in Texas are you located?
what mods on this car? only whats in the desc?
アイバンさん可愛い❤️
英語だから何言ってるかわからないけど可愛い☺️
Could you also use these parts on a 2000 986 2.7?
Yes
