SharkWerks / EVOMS 8800 RPM 3.9L 502 HP Engine Upgrade We have just finished our 8800 RPM 3.9L 502 HP Engine Upgrade. Just as the 2010 Porsche GT3s are reaching local dealerships with a new 3.8L motor installed, SharkWerks' Viper Green GT3 RS (AKA "ZKERMIT") is having its 3.8L motor removed. The 2010 997 GT3s feature a 3.8L motor, a bump up from the 3.6L featured in the 2007-2008 997 GT3. We built a similar 3.8L motor for ZKERMIT and battle-tested it for 19 months with tuning performance partner, Evolution MotorSports. So after 100s of dyno runs, many track miles (some with pro drivers), and several state highways worth of road testing, we decided to up the ante. Considering how great the 997 GT3 motor is from the factory, it's very hard to justify removing it from the car. http://videos.g33kd.net/3_9_Liter_Mo...re-removal.JPG Surgery begins. http://videos.g33kd.net/3_9_Liter_Mo...-removal-2.JPG The intake and accessory belt, hoses and electrical connections are removed to facilitate the removal of the 3.8L installed some 11,000 miles ago. http://videos.g33kd.net/3_9_Liter_Mo...es-removal.JPG Before the engine is lowered, coolant is evacuated. James must remove several covers, cross-braces and subframes, the rear sway bar, driveshafts, mufflers and SharkWerks bypass, transmission cooler lines and more. http://videos.g33kd.net/3_9_Liter_Mo...-removal-2.JPG The motor is gently removed from the car, carefully checking along the way to be sure nothing snags or extends beyond its capability. http://videos.g33kd.net/3_9_Liter_Mo...-removal-3.JPG It looks like Jürgen will be walking home today... http://videos.g33kd.net/3_9_Liter_Mo...on-removal.JPG A mountain of accessories and items must be removed in order to gain access to the internal components: fuel rails, oil filler, air conditioning lines, emission controls, Variocam electronics and harnesses, valve covers, heads, and so-on. http://videos.g33kd.net/3_9_Liter_Mo...assembly-1.JPG http://videos.g33kd.net/3_9_Liter_Mo...assembly-3.JPG http://videos.g33kd.net/3_9_Liter_Mo...assembly-4.JPG http://videos.g33kd.net/3_9_Liter_Mo...assembly-5.JPG |
The remaining accessories are removed. Each side must be disassembled independently. Heat shields, coil packs, valve covers, timing chains, camshafts, lifters... http://videos.g33kd.net/3_9_Liter_Mo...assembly-6.JPG http://videos.g33kd.net/3_9_Liter_Mo...assembly-7.JPG http://videos.g33kd.net/3_9_Liter_Mo...assembly-8.JPG http://videos.g33kd.net/3_9_Liter_Mo...assembly-9.JPG http://videos.g33kd.net/3_9_Liter_Mo...ssembly-12.JPG Bare water jacket removed from motor: http://videos.g33kd.net/3_9_Liter_Mo...tion-heads.JPG A collection of new, upgraded components to be installed: http://videos.g33kd.net/3_9_Liter_Mo...s-hardware.JPG Using the SharkWerks/Evolution MotorSports Spec 3.9 liter pistons with new liners, displacement is increased by over 8% (from 3.6 to 3.9 liters). The larger bore pistons also feature higher compression for increased torque and horsepower through the entire RPM range. There's a lot of time, effort, and R&D that went it to this so some of the specifics are going to stay under wraps. The new components reduce rotating mass by 2 grams per piston and 21 grams per wrist pin, ensuring the motor freely revs and responds especially well at higher RPMs. http://videos.g33kd.net/3_9_Liter_Mo...r-wristpin.jpg The Evolution MotorSports custom Exhaust and Intake camshafts – built specifically for the 3.9L, add more top-end power and overall performance. We set these up to be able to hit 8800rpms... http://videos.g33kd.net/3_9_Liter_Mo...-camshafts.JPG |
Re-assembly begins as James installs the new pistons and hardware. http://videos.g33kd.net/3_9_Liter_Mo...s-liners-1.JPG http://videos.g33kd.net/3_9_Liter_Mo...s-liners-2.JPG http://videos.g33kd.net/3_9_Liter_Mo...tor-valves.JPG http://videos.g33kd.net/3_9_Liter_Mo...nstalled-1.JPG http://videos.g33kd.net/3_9_Liter_Mo...nstalled-2.JPG In go the Evolution MotorSports custom Exhaust and Intake camshafts: http://videos.g33kd.net/3_9_Liter_Mo...-installed.JPG Cam timing is performed using Porsche factory tools: http://videos.g33kd.net/3_9_Liter_Mo...m-timing-1.JPG http://videos.g33kd.net/3_9_Liter_Mo...m-timing-2.JPG The motor, mostly assembled is almost ready to go back into the car: http://videos.g33kd.net/3_9_Liter_Mo...ompleted-1.JPG http://videos.g33kd.net/3_9_Liter_Mo...ompleted-2.JPG |
Once completely installed and thoroughly checked out, the car was started and idled briefly. Everything is checked again after a few minutes, and soon James has given the thumbs-up. For its maiden voyage, the 3.9L motor propelled the GT3RS on a 500 mile drive, from SharkWerks to northern-northern California's coast, to meet with Snowboarder54 (a friend of SharkWerks and a huge GT3 fan). http://www.youtube.com/watch?v=wNdwI4dmfTE Before any hard driving, the car was once again re-inspected by James. Now it's time to tune the car, which requires a 1500+ mile round trip to our performance partner and tuner, Todd Zuccone of Evolution Motorsports in Tempe, Arizona. http://videos.g33kd.net/3_9_Liter_Mo...goFinal001.jpg This also gave us a good opportunity to break-in and thoroughly road test the new motor. Somewhere in the desert, we tested the effectiveness of our green camouflage. Maybe Sand Beige would've worked better here. http://videos.g33kd.net/3_9_Liter_Mo...in-arizona.JPG Much later, the car arrives at Evolution Motorsports, to begin tuning on this pleasant 110 degree day. http://videos.g33kd.net/3_9_Liter_Mo...otorsports.jpg http://videos.g33kd.net/3_9_Liter_Mo...orsports-2.jpg http://videos.g33kd.net/3_9_Liter_Mo...orsports-3.jpg http://videos.g33kd.net/3_9_Liter_Mo...orsports-4.jpg Big thanks to Geri Amani of Redlign Autosports for enduring the Arizona heat and taking some of these shots. The car spent several days on Evolution MotorSports' AWD Mustang Dyno to tune and tweak every parameter of the fuel maps, ignition timing, camshaft timing and other parameters for safety, maximum performance, and reliability. http://videos.g33kd.net/3_9_Liter_Mo...orsports-5.JPG Todd Zuccone – Evolution MotorSports Founder and director of EVOMSit software development, used an ECU emulator / EPROM simulator module to live tune the ECU on the dyno. This type of technology allows live tuning of the ECU for instant mapping changes as well as live monitoring of the various EPROM functions. This is the kind of thing usually seen in Europe, but fortunately, we have some great footage which we will be uploading soon. http://videos.g33kd.net/3_9_Liter_Mo...orsports-6.JPG http://videos.g33kd.net/3_9_Liter_Mo...orsports-7.JPG http://videos.g33kd.net/3_9_Liter_Mo...orsports-8.JPG This is the emulator connected to the GT3 ECU which gets run through a special program on the laptop, allowing instant changes to be made to the ECU during the tuning process while still installed in the car. For a full overview of the EVOMSit Tuning process, please view this article. |
More photos of the emulator inside the car: http://videos.g33kd.net/3_9_Liter_Mo...3-9_kermit.JPG http://videos.g33kd.net/3_9_Liter_Mo..._kermit_02.JPG While in Arizona, we also tested our ultra-light straight pipe exhaust to determine what (if any) restrictions the stock side mufflers had with 3.9L of displacement. The results on our car were certainly interesting and we were able to eke out a little more performance and again save some weight (these are too loud for the street and designed for track-use only): http://videos.g33kd.net/3_9_Liter_Mo...orsports-9.JPG And finally, the results... Not too shabby eh? http://videos.g33kd.net/3_9_Liter_Mo...-93-octane.jpg 93 octane fuel, three plots on this first graph: 1) SharkWerks / EVOMS 3.9L with complete muffler bypass. 2) SharkWerks / EVOMS 3.9L with OEM side mufflers and SharkWerks Bypass Exhaust. 3) Stock 3.6L 997 GT3 base map. Stock catalytic converters, stock headers, stock intake. Tests performed in 4th gear. Todd created a different file specifically for the side muffler bypass pipes. The software needs to be modified due to the changes in exhaust back pressure: there is no such thing as one size fits all. http://videos.g33kd.net/3_9_Liter_Mo...-versus-93.jpg 91 octane fuel test, three plots on this graph: 1) SharkWerks / EVOMS 3.9L with OEM side mufflers and SharkWerks Bypass Exhaust running 93 octane fuel. 2) SharkWerks / EVOMS 3.9L with OEM side mufflers and SharkWerks Bypass Exhaust running 91 octane fuel. 3) Stock 3.6L 997 GT3 base map running 93 octane. A few things you can see- there's a big jump in tq/hp down low over a 3.6. This is very noticeable from the moment you drive. Where the factory cams/tuning begin to fall off this motor just keeps on going and going to 8800. In fact from peak power all the way to 8800 there's only a loss of 5hp. This gives you more revs to play with and you start off with more power in every gear between shifts. An even more usable powerband. It's been a fun journey getting to this point and we really feel like we've not only upped the displacement but in doing so have managed to keep the integrity and character of the GT3 motor. It actually revs even quicker and snappier than a factory 3.6 with LWF. She idles great, runs without any compromises and (to prove we're really green after some light-load fine tuning) actually managed to return on the journey home averaging 25.4mpg (a stock car going 75mph along the 5 freeway yielded 24.4mpg). For those interested in pricing and more details please see our product page or contact us. Only SharkWerks and Evolution Motorsports will be performing this upgrade, so your car can be sent to either location. The car really is peppy and a few local guys have already tried it (JWGT2, SnowBoarder54, Tony@TCDesign etc...) and the response has been good from these guys who we all look up to. We'll have the product page/pricing info shortly but we're looking forward to doing it again to a certain silver 07 GT3 with 33K miles in about a month. :) |
Amazing write up - please do this more often, i thoroughly enjoyed reading it. Like how Sharky is the wanker ;p |
i see nothing, seems there is a problem with all your hostings on g33kd.net |
wanker :lol: amazing work!! |
Great write-up, thanks! Two questions though, Porsche stated 3.8l would be the limit of reliable displacement for the GT1-block, how should that be interpreted? I see you're running on 91 octane and 93 octane, are octane levels always this low in the US? In Europe you can at least get 98 octane and 100 octane is often available too... Or does it have something to do with different octane reading (RON vs. AKI), in that case "your" 93 would equal "our" 97-98 RON? Just curious ;) Edit: Wiki to the rescue This higher rating seen in Europe is an artifact of a different underlying measuring procedure. In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe. However most European pumps deliver 95 (RON) as "regular", equivalent to 90–91 US (R+M)/2, and deliver 98 (RON), 99 or 100 (RON) labeled as Super Unleaded. |
Always enjoy reading your posts and this one simply is fantastic. There is a certain transparency and professionalism that infuses into the reader and really makes sharkwerks stand out from the rest. Keep it up! |
interesting stuff, solid numbers. |
One of the best write-ups I've seen on TS. Thanks for sharing, Dan! Kudos to both Sharkwerks and EVOMS for putting together this awesome package. Keep up the great work, guys! |
ohhhh my, you guys are insane , love it |
WOW!!! Sick work guys. Unbelievable song! |

Here's James starting her up for the first time with the 3.9. I think this was right around 11 PM that night. Sorry for the phone-quality video. :goingcrazy: YouTube - GT3 RS secret motor |
Was just checking this out on another forum, again awesome work guys |
One of the engine's (with the higher miles- who could that be?:) is getting more of a work-over... In the connecting rod department we do feel it necessary to get new rod bearings and bolts. Here's you can see a comparison between the pankl GT3 rod and a Twin Turbo one (yes I know it's a little bent lol!): http://videos.g33kd.net/gt3rods_v_tu...s/P1110996.JPG The Titanium GT3 ones are obviously lighter but by how much you ask?:) http://videos.g33kd.net/gt3rods_v_tu...s/P1110995.JPG Certainly helps the GT3 rev quicker;) http://videos.g33kd.net/gt3rods_v_tu...s/P1110994.JPG So after 37.5K on this motor you can see that there is indeed some decent wear on the rod bearings, which we're replacing. http://videos.g33kd.net/gt3rods_v_tu...s/P1110997.JPG http://videos.g33kd.net/gt3rods_v_tu...s/P1110999.JPG All well and good but never mind the work to do that but because we're dealing with one-time use stretch bolts you need 12X new ones: http://videos.g33kd.net/gt3rods_v_tu...s/P1120020.JPG http://videos.g33kd.net/gt3rods_v_tu...s/P1120021.JPG Take a long hard look at this $58 dollar bolt:P At least the bearings are only $19 a piece.... |
A few more fun things for today fellas... In go the lifters.. http://videos.g33kd.net/cam_timing_g...s/P1120010.JPG And the intake plus exhaust cam shafts... http://videos.g33kd.net/cam_timing_g...s/P1120023.JPG There's a few fun tools here including the factory timing blocks that you can't really see... It's a two person job really with some MEGA wrenches:D http://videos.g33kd.net/cam_timing_g...s/P1120013.JPG On goes all the top side "faff" including the wiring harnesses, intake manifold etc... http://videos.g33kd.net/cam_timing_g...s/P1120037.JPG One other change we're making is removing the gt3 pulley in place of the RS one (also used on new 2010 997GT3s mind you) as we're getting a much more rev-happy engine here... Original one comes off: http://videos.g33kd.net/cam_timing_g...s/P1120038.JPG On goes the RS one... http://videos.g33kd.net/cam_timing_g...s/P1120041.JPG In reference to the earlier post about the factory rear main seal and the leaking you get... this is a picture of how it's supposed to look- no leaks with the 996gt3 one. http://videos.g33kd.net/cam_timing_g...s/P1120046.JPG |
Been busy for a few days so here's a few more updates and for the silver car;) Here's those magic steel liners that help make the bigger 3.9L bore possible:D http://videos.g33kd.net/end_of_builds_gt3/P1120093.JPG Those trick head studs: http://videos.g33kd.net/end_of_builds_gt3/P1120103.JPG The rods along with new bearings and new rod bolts: http://videos.g33kd.net/end_of_builds_gt3/P1120090.JPG And installed: http://videos.g33kd.net/end_of_builds_gt3/P1120104.JPG All in... http://videos.g33kd.net/end_of_builds_gt3/P1120141.JPG Gasket... http://videos.g33kd.net/end_of_builds_gt3/P1120109.JPG More.. http://videos.g33kd.net/end_of_builds_gt3/P1120134.JPG Some cam timing (two person job along with some factory tools and then some:D) http://videos.g33kd.net/end_of_builds_gt3/P1120152.JPG Most of it assembled... http://videos.g33kd.net/end_of_builds_gt3/P1120155.JPG Ready to go back in the car... http://videos.g33kd.net/end_of_builds_gt3/P1120157.JPG Back in the car... http://videos.g33kd.net/end_of_builds_gt3/P1120173.JPG The "stereo":) http://videos.g33kd.net/end_of_builds_gt3/P1120089.JPG Then looking to the other lift we have a pair of other 3.9L's:D http://videos.g33kd.net/end_of_builds_gt3/P1120184.JPG |
But the silver one was not yet done... Slight smell of coolant in the front and with 37.5K of unprotected mileage the front radiator was a little worse for wear... Off came the bumper... http://videos.g33kd.net/end_of_builds_gt3/P1120105.JPG With some cleaning look at some of the stuff she'd collected: http://videos.g33kd.net/end_of_builds_gt3/P1120110.JPG Here's the old one vs' the new one... Not a pretty sight;) http://videos.g33kd.net/end_of_builds_gt3/P1120112.JPG With the new radiator in place we added some protection with the Cargraphic screens: http://videos.g33kd.net/end_of_builds_gt3/P1120124.JPG http://videos.g33kd.net/end_of_builds_gt3/P1120125.JPG And now the silver one is ready for some action again.... but before you know it in comes another whitey:P http://videos.g33kd.net/end_of_builds_gt3/P1120182.JPG |
This is such a nice build. This car must be a beast with that much HP and high rev. Great work! |

Thanks for all the interest, support and encouragement during this entire process guys... It's officially released now;) I know there are a lot of Excellence Magazine readers here and some may have already seen it and ours just came in today. The latest issue (April 2010) features a familiar face on its cover: http://videos.g33kd.net/997/gt3/2007...nuary-2010.jpg With minor revisions to the graphics and a new set of wheels, ZKERMIT is back with its 500-HP, SharkWerks-built 3.9L motor to run alongside a red 2010 GT3 (this car may also look familiar, as it's owned by a SharkWerks customer and is featured in our project gallery here). ;) http://videos.g33kd.net/997/gt3/2007...-january-3.jpg The article covers the editor's 1000 mile road trip in our car, through the finest backroads and hills to be found in the northern California coastal area. Be sure to look for this issue at news stands and bookstores for all the high quality photos and some other good articles. The article can be previewed by following this link. More information is available in our 3.9L product page here. http://videos.g33kd.net/997/gt3/2007...-january-4.jpg In case anyone wanted to see how the car looks with its new image, here's a quick video: http://www.youtube.com/watch?v=txd9B1ZUhqk |
Hey guys, It's been a while since we updated this thread, so I thought I would post some new pictures. We now have a few more 3.9L motor upgrades in progress. Our 996 GT3 was started, but with customer cars coming in, it took the back burner and will probably be completed some time later this month. The current focus for James is completing two customer 3.9L 997 GT3s. Both happen to be white non-RS models. So many white cars! http://videos.g33kd.net/997/gt3/2007...-Canada_06.jpg First up, the domestic GT3 shipped to us from southern California: http://videos.g33kd.net/997/gt3/2007...rade-white.jpg http://videos.g33kd.net/997/gt3/2007...e-white_02.jpg Bumper removed: http://videos.g33kd.net/997/gt3/2007...e-white_04.jpg And more: http://videos.g33kd.net/997/gt3/2007...e-white_05.jpg A void in the engine bay: http://videos.g33kd.net/997/gt3/2007...e-white_06.jpg Ah, there it is: http://videos.g33kd.net/997/gt3/2007...e-white_07.jpg Coming apart: http://videos.g33kd.net/997/gt3/2007...e-white_09.jpg http://videos.g33kd.net/997/gt3/2007...e-white_10.jpg Old pistons/hardware: http://videos.g33kd.net/997/gt3/2007...e-white_13.jpg New EVO studs: http://videos.g33kd.net/997/gt3/2007...e-white_11.jpg Coming together: http://videos.g33kd.net/997/gt3/2007...e-white_16.jpg Shiny horsepower: http://videos.g33kd.net/997/gt3/2007...e-white_17.jpg http://videos.g33kd.net/997/gt3/2007...e-white_18.jpg SharkWerks/EVOMS 3.9L spec camshafts being prepared for installation: http://videos.g33kd.net/997/gt3/2007...-Canada_08.JPG http://videos.g33kd.net/997/gt3/2007...-Canada_09.JPG Cam timing: http://videos.g33kd.net/997/gt3/2007...-Canada_10.JPG http://videos.g33kd.net/997/gt3/2007...-Canada_11.JPG And it's almost done being re-assembled... then it will need to be installed, tuned and tested extensively prior to delivery. I mentioned there were other 3.9L cars at our shop. The other 997 GT3 shipped to us all the way from Quebec, Canada for the upgrade. Here it is, parked next to another Canadian car, a 997 Turbo: http://videos.g33kd.net/997/gt3/2007...ade-Canada.jpg It's interesting that we actually have yet another 997 Turbo (cabriolet) here from Canada that will be shipping back this week. And before it has a chance to begin surgery, another 2010 997.2 GT3 rolls-up for a quick update: http://videos.g33kd.net/997/gt3/2007...-Canada_02.jpg Disassembly begins: http://videos.g33kd.net/997/gt3/2007...-Canada_03.jpg Motor removed: http://videos.g33kd.net/997/gt3/2007...-Canada_04.jpg http://videos.g33kd.net/997/gt3/2007...-Canada_05.jpg http://videos.g33kd.net/997/gt3/2007...e-white_07.jpg A regular track junkie, he asks us to rebuild his LSD with Guard: http://videos.g33kd.net/997/gt3/2007...-Canada_07.JPG With all of the parts ready, James continues to assemble motors into the night... More pictures and video to follow soon. Thanks for reading. |
So with the cam timing done... [http://videos.g33kd.net/997/gt3/2007...inished_06.JPG The rest of the engine is assembled and goes back in the car. The final touches include our exhaust (and tips) along with the 91 octane EVOMSit tune and she's ready to rumble or be broken in as another SW 3.9L is born: http://videos.g33kd.net/997/gt3/2007...inished_14.JPG We also added the gt3 radiator screen kit for protection: http://videos.g33kd.net/997/gt3/2007...inished_07.JPG http://videos.g33kd.net/997/gt3/2007...inished_12.JPG With a couple of hundred break-in specific miles done we did the first oil change and now she's ready to be picked up and back off down to the Los Angeles area;) http://videos.g33kd.net/997/gt3/2007...inished_15.JPG I'm going to the airport to pick him up in Kermit too:D http://videos.g33kd.net/997/gt3/2007...inished_16.JPG The Canadian car is a couple of weeks away from being picked up but I'm especially interested to see how much of a difference there is from the LSD work performed by Guard. As a company I can't say enough good things about them. In fact, our 996 GT3 diff is over there right now;) |
Lucky owner no doubt! |
Very cool stuff, guys! Glad to see you're staying busy. Can your 3.9L engine be swapped into the 996 GT3? |
