Hi Guys,



This is what I've built over the last months













and here are the results on the Dyno yesterday ; 368 Hp and 440 Nm ( 330 Ft-Lb I think ? ) of Torque @ 0,4 bar ...



By the way : the thinner line on the first chart are values from the days when it was a non Turbo ...













Have to get some Km's on the odometer and then back on the Dyno for 1 bar of pressure and something like 525 Bhp ....



Not bad for a simple dutch guy, is it ?



Cheers, Frank

Haven't seen this set up before, where is the impeller and what is the aluminium cylinder in the front of the engine bay? Very nice power readings. Look forward to hearing more about its performance.

Is that a PWR water to air intercooler? Where did you put the radiator and fan?



What boost were you running and what size injectors? Did you have to upgrade the fuel delivery pump from the fuel tank to cope?



Looks like an excellent build.

WOW! Not sure I would do it to my "Baby", but I sure would like to have 368 ponies to play with! Look out Corvettes!!! Does the 6 speed trans and Diff handle all this new found power okay???

You gotta post some info!!!! What kind of engine work/prep, general setup etc.....

We started from scratch. Took an old 968 engine and had it re-alusiled. Wössner in Germany made the pistons on a 8,5 : 1 ratio and some Australian guy sold me the con rods via Ebay. Crank is a polished standard one.



The Turbo is under the home made inlet manifold and is a Garrett GT3076 with an 0.82 AR, rather modest for a 3 liter engine but should be good for some 525 hp @ 1 bar. It stands on a home made engine-support ( is this the correct word for it ? ). It currently runs on 0,4 bar of pressure which you can see on the second chart in my first post.







The inlet manifold ; from mold to product :











We chose for a water to air PWR cooler ( the cylinder in the front of the engine bay ) which has the radiator and it's own fan on the airco condensor location. Since my car is a true CS ( with M030 ), I don't have airco or any other luxury equipment. The electronic signals are being sent by a VEMS programmable management system, the pressure handling is done via a Blitz boost controller.



Injectors are 675cc Siemens on the standard fuel pump.



Then the gearbox and <acronym title='Limited Slip Differential'>LSD</acronym> : do any of you guys run a 968 with similar power output and experienced any problems with the gearbox or <acronym title='Limited Slip Differential'>LSD</acronym> ? I know mine is working fine at this moment but will it hold the 525 hp ? if not what's the solution ? I can't find much info about gearboxes here, I did read the topic on the RL forum but that's all about changing gears and final drive while I'm looking for info for a stronger complete gearbox ...



Finally, this is what my 968 looks like now ...











Cheers, Frank

Yeah, the 01e should be good for 525. Nice ride. You might want to consider changing the gearing to utilize the turbo better. Turbo s had longer gears. Im hoping to start tearing my 93 apart, for a turbo conversion by spring. Gonna finish my 86' with a widebody conversion first.

Nicely done! I wish I had the money to take on such an endeavor, I planning on going the SC route, which I think to be my best option.



Until then I will silently live vicariously though you and the others. Again very nice!

What a beast! Very impressive work . Would love to see some videos on You Tube at some point. Thanks for sharing!

Yee gods that's sexy!



Is this a street only machine? Or will it see some light track work too?

Looks like a very clean and well sorted installation. Overall your car is beautiful.



Congratulation and enjoy driving,



Jay

WOW! DOUBLE WOW!! That's a very impressive piece of work, especially considering the rarity of these cars, I'm sure you had to do everything from scratch, with very little, if any, guidance. OK, on my way to pick my jaw up off the floor...

Thanks guys !



Has indeed been a challenge to get all bits sorted out but a real challenge is what makes (car)life worth living, isn't it ?



The car does see the Nordschleife on a regular basis ; and some tracks here in Holland ( Zandvoort ) and Belgium ( Zolder / Spa Francorchamps )







Cheers, Frank

Holy Crap! That was easier than typing a whole jealous paragraph <img src="/forum/images/smilies/968/smile.png" class="smilie" alt="" />

Gauntlet down Bob. New injectors, that fancy water cooled intercooler, chip, a tad more boost and a disclaimer that your not responsible <img src="/forum/images/smilies/968/rolleyes.gif" class="smilie" alt="" /> DR1 SC upgrade kit on the way <img src="/forum/images/smilies/968/wink.png" class="smilie" alt="" /> .

Just curious - how's the throttle response? With the compression dropped all the way to 8.5:1, the engine definitely has the potential to endure monster boost without detonation. Is there much lag? Again, I'm awe-struct by the apparent quality of your work.

Very nice looking build. Impressive power for only 0.4 bar boost.

Throttle response is somewhat better then stock, since we got rid of the Dual mass flywheel and clutch and installed a new Spec clutch and Alu flywheel. The throttle body is also bigger dan stock ( 70 mm ). I've done only a few Km's yet but did not experience any turbo lag ; pressure is there from 2000 rpm on and it's ready to rock from 2750 rpm on, a rev count that I don't use that much in normal traffic.



The thing I did notice is that it is a very driveable car. My right foot determines whether it runs like a well awakened 968 or like a well awakened F16 <img src="/forum/images/smilies/968/wink.png" class="smilie" alt="" />

Some extremely nice work. Most impressed with the fit and finish it really looks like a show piece but one that will smoke most 911s



Way to go!

" one that will smoke most 911s "



I'm guessing it should smoke most 911 Turbos.. as for the regular 911, even the GT3s, will probably be embarassed.. <img src="/forum/images/smilies/968/glare.gif" class="smilie" alt="" />

The conventional wisdom on 968 turbo builds has (rightly) been that they are truly custom, one-off mega-dollar affairs. But now that we have two recent examples, and one (Monstrous') in the planning stages, is there any chance that those who have recently created these magnificent beasts could put together a "How I Did It" (Young Frankenstein reference for those old enough to remember - kind of a fitting one, I must say...) guide for those of us to consider when that winning lottery ticket turns up, or, more realistically, when the kids move out of the house?



I realize each of the recent examples are still very much custom creations, but I'm wondering if they could somehow form the genesis of a more-or-less standardized package, including designs for the intake and exhaust manifold and mounting brackets for the intercooler (that a local fabrication shop should be able to replicate for less than the cost of a new Cayman), along with recommendations for pistons, connecting rods, injectors, modifications to the ECU, head studs, and whatever else goes would go into replicating one of these amazing motors. I realize it will never be a straightforward bolt-on affair, but it would be nice to see a few more of these 911 Turbo killers rolling around.



Thanks.
