@@user-th6wn6xi1g lol, yeah me as well. I was pleasantly surprised to play a tune on them after the first thud!

@@Gunsncarsnstuff lol, truly. When driving these cars it's as though they will take on anything.

@@protomotive Is that your car in the video? or are you the drone operator?

​@@Gunsncarsnstuffmine is Polar Silver 🙂 This is a customers car we had just finished. I fly the drone as well.

@@dr.killebrew1983 I'll see if I can dig it out and do a part 2 🙂

Yes, they're awesome! Do you have a 993tt?

@@AAAAAK5 we build systems for Porsche only. Maybe try Dallas Performance or Hennessey. I think Prototech in Florida did a 348 maybe 10 years ago as well.

@@protomotiveThank You Sir ❤👍

Nice :) Lol, mine are anything but subtle. They're acid green like the Porsche 918 Spyder!

I went crinkle black, love them.

@@jordans4366 Awesome ! We will love to see final pics of your install 🙂And of course feedback on performance!

Best with proper octane, pump+met, race fuel or the favorite E85 :)

Yes we've done some really fun na upgrades on the 993s as well. What kind of build are you after? Big displacement? High rpm race? General performance updates?

@@protomotive I am tempted by the 4.0 L builds but don't need to go that far. I and looking for performance updates and upgrades with a solid increase in mid - range torque. Love the ideas of bumping up RPM's somewhat too. Would love to talk about options and budget.

@@jameswalter3136 Well, the increased stroke would definitely help that out! But yes, there are many other options as well. Feel free to give me a call, or shoot over an email to sales@protomotive.com and we'll figure out a nice upgrade path that makes sense now and in the future :)

@@toddknighton I did and he's quick!

I'm glad you're enjoying them! There's so much more to these engines than what you'll find in the shop manuals! We'll keep diving and finding even more :)

Luckily the heads are a bit narrower than the bore spacing so there's nearly a 3/16" or 5mm gap between them. So even where the fins are solid, there's still an air channel to help cool them down. It'd be interesting to 3D print these instead where you could route cooling between the back side of the combustion chamber and studs for even better cooling than oem. You might even get away with a 4 valve air cooled turbo head that way too. Stuff conventional casting / machining is not capable of doing.

​@@protomotiveindeed. I've seen similar billet heads where we measured about 20% drop in cooling airflow. We did cost up a printed head but the amount of machine time meant they were $6000 each before we even got to machining. I was also looking at ways to manufacture new exhaust port heat shields to help replace the missing ceramic liner.. meanwhile, 4v heads will always be extremely limited on power. I can't imagine those Swindon heads will support continuous power above 300hp.... water cooing ala 935 /956/959 is the answer now we can buy 200W water pumps cheaply there's no reason not to....

​@@robertcorbishley1712 no doubt 3d printing them would be 3x cost. But does have interesting advantages :). I did reach out to Swindon on the 4v stuff since we had many inquiries for using them on turbos. Like you I knew they'd be limited as Porsche already did the research and fixed it with water cooling on the 956. Swindon rates theirs at a max 500hp which may work na on a nicely built 4L. I personally wouldn't turbo them though.

Thanks for the correction. I didn't know Bob had come up with that design. I have tremendous respect for him. He's been quite the innovator in this industry!

All good and we got a few more sets of flame rings here if need them. Also setup sheet specs. Done many sets of these heads with Brian, including the 1st 993 set. All turned out excellent. More than a few won many races. Few sets ran with Jim Higgs JB Racing steel lined cylinders / CP X forged pistons, excellent results. Nice works. Very informative vid, love it, thanks for sharing. @EuroPartsWest @protomotive

@@bmday77 Good to know. Shoot me an email with the spect/setup sheet and pricing/availability on the flame rings you have there to sales@protomotive.com. Be sure to check out part 2 coming up this weekend, I hope. It covers all the thermal expansion rates and strength of materials. We found a few surprises in the data that was fun to share :)

You're very welcome :)

The little tiny one? Building a go-kart? Lol :) Or the big ones?

@@protomotive the big ones in front of yall

@@alexq624 Amazon, lol. Pulsar s480 turbo. 1.1 a/r. Compressor wheel is 80/113mm 7 blades 7 splitters. Turbine wheel is 96/88mm. That's the one with the antireversionary compressor housing powder coated red at the end of the video.

😎

@@cyrilperroud1130 that's awesome to hear! Yes a conventional gasket is used on the exhaust side on these. I'm sure Pauter would be happy to machine an oring groove in the exhaust flange if we requested it. Be sure to watch the next video in this series. I go over the strength of the different alloys vs temperatures. There's some surprises in there for sure!

Just when you think you got it.... I say otherwise.

Sweet!

@@kidnplaye4630 is there anything in particular I can help with?

Yes, but be sure to put the nozzle on the outlet tank. You never want to fill the intercooler with meth.. It'd be a bomb waiting to go off! Meth inj does have a purpose and functionality and when done right. It cools very well and raises the octane and only consumes when in boost. Otherwise you drive on normal fuel when you don't need it.

Yes :). We also have many mini jigs where we produce headers, exhausts, intercoolers, ypipes and all kinds of goodies for 996tt and 997.1tt. Even 991.1/991.2tt xpipe exhausts :). What are you after?

Thanks!

Lol, thanks :) I thought the POV of the boring head was pretty different, so I had fun with it :)

@@protomotive Are you at all nervous machining these expensive cases or can you just do it in your sleep? LOL

@@joebolognio5508 The liability is high, yes. This particular one was a brand new 4.0 Gt3 case from Porsche with brand new liner carriers. And having to work with 0% defect rate should make anyone nervous!

@@protomotive Very impressive!! Well done!!

Yeah definitely one of those underappreciated jobs for sure!

@@HORUS9 the tpc kit has been a great option for a nice cost. There's another kit made in the UK by ern or something like that. It's similar in cost to the tpc kit but a twin turbo system. We tune a lot of cars for both kits. But haven't bothered with making a system for the boxster since there's not only those but many shops custom fabbing systems for them already. So check them out and give us a shout when you're ready to tune!

@@protomotive thanks a bunch !!

@@HORUS9 you're welcome.. It was mrn not ern sorry. Here's a link. The tuning isn't great for the US cars. Maybe good there. www.mrnracetechnologies.com/

@@protomotive I've spoken MRN before.... They only deal with the 3.4 DFI engines and mine is a bit older so TPC is basically the best option.

@@HORUS9 hmm. The MRN cars I've tuned were all 987.1 Caymans. Non dfi cars. Basically your car just a cayman vs boxster. Yeah, here it is. 987.1 version www.mrnracetechnologies.com/product-page/987-1-twin-turbo-conversion-usa. But the tpc kit may be more readily available. Actually I can get them for you if you'd like. I am a dealer for them :)

I should hope so! 😊

Great show!

😂 Yes, thouest intercooler ist most grand! 😎

For sure. We should probably make a full video about it!

Lol, right? Then send it back out into the battlefield!

@@protomotive the true hillbilly way 🤣

@@sammybalamby Well, we are in Arkansas! I hear Banjo's playing in the back woods sometimes, lol :)

@@sammybalamby Well at least Arkansas FINALLY got a Porsche dealership :) Just opened in Little Rock. We are catching up!

Lol, yeah... And those are little guys compared to a lot of the turbos we run these days!

@@protomotive 🐌🤯

@@sammybalamby 😂🤣

@@toddknighton Lol, a single gt3794 like we ran on the orange GT2 produces as much as a pair of those gt2860rs!

There are definitely a few annoyances with the Abs/Psm system on the 996tt. My personal car was doing a strange thing where it would tend to lock up the front right tire in cold weather right in the middle of a corner. That turned out to be the Yaw sensor in front of the shifter. No errors... On the track, the PSM tends to lock up when part throttling out of high speed corners. There's a hack for that where people install a switch to disable the yaw sensor once you're started up. it won't flag any errors, keeps the Abs on, but disables the PSM which is cool. The better way to go is to install a GT2 or Motorsports ABS unit and remove the psm. With that done, I can code out the PSM from the ecu and all is happy again. So, there's a few tips for ya :)

@@protomotive my yaw sensor was doing a lot of random shit on my Autel diagnostic

@@protomotive Fabulous info, do you have a link?

@@sidewayssam this is from Planet 9 forum. Actually the "wiring work" is really easy. Not harder than hard wiring a radar detector. Just locate the Yaw sensor under the carpet on the hump, by the drivers right shin. Cut the ground wire (brn/yel) and install a rocker switch between the two ends of the ground wire. When you want PSM OFF, turn the switch OFF. When you want PSM ON, turn the switch ON, and cycle the ignition. I soldered in longer wires an installed the switch on the trim panel under the parking brake. This trim panel is really cheap and simple to replace. Plus the switch is easy to reach. On the street or in the rain, I have it ON. On the track, in the dry, I ALWAYS have it OFF. actual link: www.planet-9.com/threads/psm-on-or-off.27747/page-3

@@sidewayssam Mine never flagged an error for it, but replacing it solved the issue I was having. I did find a Non-PSm ABS I was going to swap out, but never seem to get the time to tackle that one.

Lol, Sorry? Yeah, there's just soooo much you can do with them :) They're an outstanding car to purchase for a baseline since they can grow with you.

Just showing off my Cat like Reflexes! :)

@@protomotive i think keenan has better reflexes than a cat!

@@sammybalamby Lol, no joke! I had to record him catching his toy in super slow mo and it almost looks like normal speed!

The TSB was on the 3.8 and 4.0 GT3 engine case freeze plugs, but is relevant to the 996tt/997.1TT engine cases as well. It was showing how to properly stake the freeze plugs in place to keep them from blowing out randomly. It was showing the large one by the bell housing on the bottom of the case, and the other large one inside the bellhousing. When you purchase a new engine case, they've learned the hard way and do stake them properly. I searched for it for a while and can't seem to locate it. When it turns back up, I'll shoot it over to you. It was originally sent to me by our distributor in the UK, NineExcellence. Ken may have it floating around.

Lol, yeah, tongue tied.

you got it eventually :p

@@sammybalamby yeah....

No, the drill for the 12mm studs perfectly clears the original hole. For the 7/16" head stud kits we use timeserts since the difference isn't great enough to allow perfect threads. But the 12mm threads come out beautiful and don't require the extra work on timeserts. :) BTW, never use helicoil! Timeserts are nice. Helicoils come out and don't add any strength.

With you as well!

Lol, yeah, only the US cars have a clutch switch. Apparently Porsche doesn't trust us silly Americans to not drive our car through the wall. Or the lawsuits they had early on forced the issue. Since all my cars have clutch switch disabled, it's just a force of habit to be sure they're always in neutral before starting.

Yes the k16s hit a wall in the low 600whp levels with big compressors where we've run k2471s up to 900 crank hp! We talk about that in our other video series as well :)

Thank you! We're glad you're enjoying them and learning at the same time :). 😊

Combined with great editing ❤️

We're working on it!

Me too!
