Fredrik speaks!!!

Fredrik may have the ultimate 8v 3.1 yet....years in the making....!

Chris White

Keep in mind that the 16v power shift (1krpm) is mostly due to people using the stock cams in the stock timing...there are ways of addressing that!

C ANDERSON

The car will mostly be a street car maybe a few DE's . Been using the S2 for DE's since it has all the suspension mods . also have another stock 951 .
Sure would look good with a 16 valve head !

Also have a S2 trans with LSD could use with it.

Thanks for all your help.

I have read this whole 3.0 registry at least 2 times and still can't decide.

Thank you,

Mine is currently waiting on an engine stand (hope it doesn't bend!) with everything else for it sitting neatly in boxes beside it patiently waiting for my return so I can begin installing everything...

If I continue to spread info at this pace, in 15-20 years the spec will be common knowledge...

Yes, its been in the making for some time now, and it started with me getting in contact with Rennlist Official Clown (Lart that is). I bought an S2 longblock from him, and as I was hunting for some other parts, he directed me to Chris.

So, the block was shipped from California to Marietta, and then the madness began. From the beginning the spec and budget was kinda limited, but as time passed and my career started to develop (and my knowledge about these cars), we came up with a spec that now feels really good. Chris has been a lot of help here, suggesting parts and solutions, thanks CW!

Now we are entering the final phase of the build.

So the basics are:

3.1L MID block with piston squirters, gt35r turbo and SFR stage II headers.
Some head work will be done...

Tuning will be handled by Duke, an of course he has been a lot of help too!

Chris and Duke, I got no secrets about this one, so if there is anything that should be mentioned, please do so

so chris do you think twin exhaust cams clocked in with no overlap is the answer ??

Chris White

Don't forget the dry sump system, the new radiator w/oil cooler, SFR intake, Nice rods, Wossner pistons, knife edged crank, aluminum flywheel, custom Kevlar clutch, Milledge cam and the head work is being cone by my specialist – the same guy that massage the head on the 440rwhp @ 16psi 2.7 engine a couple of years ago.

We are getting close…the head work has taken forever but the guy is a little fanatical about his work. Copper barium seats, custom manganese guides, custom valves (almost 50mm intakes – this only works because of the 106mm bore), the ceramic is diamond bit ported – so far the flow increase on the exhaust port is over a 30% (approx 210cfm)

This one is the top of the line 8v engine….

Chris White

A combination of low overlap and event timing. I will be really tweaking the valve timing on the engine dyno shortly (man, making the adapters is just slow work!). Playing with the intake timing will change the tuning of the powerband. Once that is done we can see where changing the cam profile might yield more power….

Chris White

To be honest with you the 8v set up is a better choice to 90% of applications. The 16v stuff is about getting every last bit out of the displacement and it is also about just being a little different. I have worked on 600hp 8v engines – you don’t need that kind of power unless you are GT racing. So I am sure you can make enough horsepower with an 8v to accomplish your goal (street / DE). On the other hand opening up the hood and showing a 16v does have a certain visual impact that many people like.

I’ll just give you the quick pluses of each –
8v
many parts available
Track proven for many years
Lots of tuning info available
Low end torque

16v
Top end power
Exclusiveness
Efficiency
Just plain cool…!

Take you pick!! If you want any other candid opinions feel free to drop me a line – chris@944enhancement.com

C ANDERSON

Thanks Chris,

I believe losing bottom end power would not be worth the cool factor , there is another side to 8v who would know it is a 3.0 ? Stealth.

And if a 16 valve head gets hurt gonna be expensive to fix and seeing as how have a real nice S2 will keep the S2 head around for a spare.

Thanks again ,

And to get this master piece the supporting goods it deserves we have FueLab digital 1300 hp fuel pump and fuel filter, upgraded fuel lines, CEP fuel rail, 1200 cc injectors, Link G4 EMS, new engine harness, large intercooler, Tial BOV+WG etc... there will be many hours spent on setting up the EMS-system to perfection.

C ANDERSON

But that is the fun part !

Have most of the supporting hardware from the prior 2.5 will need to move up the injectors. more countless hours tuning, my favorite part .

Decided on the 8 valve so will be moving forward soon. thanks for all of yall's help that is an official word in Mississippi.

And I hope you are going to make sure Fredrik has some really good brakes...

Fredrik H

As the caring guy Duke is he set me up with a pair of Volvo 142 drumbrakes, for a killer deal of 3k... Machining included..

No seriously, steel braided lines and 993tt rotors and calipers installed..

Tom M'Guinn

Did someone say stealth? Here is my 3L dressed up to look like a factory 944 turbo. Only the most diehard 944 fan would be able to tell the difference (based on the coolant port at the front of the head).
