The torch forum ? Is that where you're getting raked over the coals relentlessly for using Divlars by that former poster ? What wuz his name scabbykneez930
You know I jest. Much respect to the Kman for his build. Now you just need to get a real turbo and turn the boost up

Mr. 70'sBush, I wonder if FreakyKeniky's "torch forum" comment was a tell regarding his counter culture lifestyle - torch 'v' flame - hmmmmmm ?!?!?!

Butt that Dilivar torching idea makes sense, too (unlike the idea of using Dilivar - egads, USED Dilivars, even - in a fresh engine build! )!!!

Big ports don't fill the cylinders well at low rpm. Port velocity is low and atomization is poor. Big overlap cams make it worse by lowering the dymanic c/r.
The only way to claw back some off-boost torque is to raise the static c/r.
This is most likely why the factory did small ports and no-overlap cams; to make the Turbo a little more driveable off boost. I recall that no one liked the driving characteristics of the Turbo Carrera with bigger ports and a 6.5/1 c/r.

Surprised the K27 falls off at such low boost. You know what that means? One must use a modern turbo!
That's my plan; Give my car a Garrett for Christmas

Sorry no update in a while. My schedule dictates small clumps of time when I can work on my own stuff. Our focus is exhaust systems so I'm building a custom system for these mods. A client wanted to do the same build so that is where my custom headers went. He also got my custom turbo. That build should be done early January so hope to have some data.

Thanks for the reply, Brian.

If your stuff isn't perpetually on the back burner then you're not a good business owner. I'm looking forward to seeing some pics of the headers you came up with and seeing some dyno numbers of you get them.

By the way, I bought a set of NA headers off you about 9mo ago for a 3.4L high butterfly project I was doing. We made 315hp at the wheels.

Woh, that's a big number!

Yes it's a little frustrating as I am anxious to see what this engine can do. It's still pretty much stock and runs really strong. Slowly but surely we have replaced all the aged worn out items. This car was a shed rescue that had never seen the first hint of maintenance best I can tell. Now it's a really nice driver.
The owner has promised pictures and data once the engine is done and they get the car to a dyno. We have some CIS work to do as the power level should be far beyond typical range.

We were pretty happy with the results. Here's a video of one of the final pulls of the day: https://www.facebook.com/TLG.Porsche.Service/videos/1256719951035914/

Brian have you had time to get this project wrapped up and dyno tested?
Just curious what you ended up with in terms of configuration and output.

I have put the entire package together twice now and have been contacted by clients who wanted to do the same to their engines. So twice built twice sold and still not on my 930. Both clients were EFI so I cannot use their dyno data as I am sticking with CIS. My estimate is that full engine management of EFI and ignition will gain 50-75 HP at the wheels over MSD and CIS. The focus becomes drivability; it's not difficult to make power with these engines but it is more difficult to tune in off-boost torque with huge heads and big cams. That is really where electronic engine management has it's greatest advantage in my opinion. Could be we end up with electronic ignition control but fuel will remain CIS as I want to see what I can get out of it just for my own curiosity.

I remember around 9 years ago there was a guy in Sweden (I think it was Sweden) that got around 600 HP with CIS.

I think he was using a CIS Flowtech fuel head and enlarged intake ports in the heads and bored out flat intake manifold ports to match but I don't know what all else he did to the motor, what cams, or what was done to the fuel head... or if it would idle.

I guess a search would eventually find the post if it's still there.

I think you are taking of a 2.7L based motor with fabricated center box feeding the spider runners. The CIS was lifted from a Porsche 928 V-8 motor. The two additional injectors were plugged into the system for extra fueling however I do not recall where. Also do not recall I it was twin turbo but power level suggests it was.
Fuel, high boost, probably high revs. I do recall it as an impressive level of innovation given to a collection of realitively inexpensive components making that power.
Search 2.7L, just like the very first 911 Turbo.

Jim, the fellow you are referring to's name is Micke. He was able to get big power using progressive boost in the midrange. The boost was tailored to correspond with the fuel output of the CIS. I don't plan on doing that but may need to if it starts to go lean at the top. The flow tests I've done on my modified CFT 007 unit shows it will support 500WHP.

Marty, the guy you are referring to did build a twin turbo 2.7L with 2 extra fuel ports using a 928 fuel distributor. It was a really outside the box thinking kind of build. However, I am interested in achieving matched flow per cylinder using only the six 009 fuel injectors. I have headers built with O2 bungs on each primary so I can adjust the FD and balance the air flow and fuel. Having all 6 cylinders average 12.0:1 AFR at redline on this engine ain't gonna cut it.

Do you have a data logging system for 6 F/A simultaneous readings?

Why do you need that? It would be expensive and difficult to do with anything off the shelf. I suppose you could whip something up to measure 6 voltages and convert them, maybe an Arduino or something would be a good choice.

However, 6 EGTs gives you just as good a fidelity if needed. It does make an excellent diagnostic tool to help you determine things like sticky valves or a fouled plug, or even which plug top/bottom if you can turn then on/off separately. I could see using the info for trimming the injectors on an EFI setup as well, but even there EGT is good enough.

The shop we used to dyno test our exhaust systems does. I want to do this one myself and planned to cobble together 6 AFR gages so I could tune the fuel distributor while the engine was running. It may not be feasible but I'd like to try it. I have all the parts needed and the O2 bungs are already in the header primaries. Course at this rate it may be a while before I have time.

That bank F/A can difficult to monitor and expensive.
Wanted to offer the aircraft world has combined gauges for 6 cylinder air-cooled motors that displays 6 EGT plus one TIT in side by side bar form. It will switch to give you CHT in bar form comparison

Not F/A however these are the long established standards for air-cooled performance and monitoring as they have the same problems with air manifolds and MFI not taylored to each cylinder in factory builds.


If our old friend Bob Farmer would share his findings relating to 911 cooling distribution and his fixes this would be of great helping holding CHTs equal for maximum spark advancing.
Anyway with CHT on all 6 you'll have this to consider also.
