Looking at the pics of the 934 motors is it my imagination or are the fuel heads on those motors bigger than the stock 930 fuel head or is it a optical illusion?

Incredible information and exactly what I was looking for. After reading your
post the intake air issue really cleared up in this old head. It makes perfect
sense and very well may be why the air sensor plate issue existed in the first
place. Again you never cease to amaze me and I much appreciate your help.


G Man:

I used 6 AN braided teflon lines from the pumps through the filter and
accumulator and to the fuel head regulator and the same on the return
lines. I used 4 AN braided teflon lines from the fuel distributor to the
injectors. The ID of those lines is approximately 20% larger than the
original lines ID's.

I have read that the 934 fuel distributor was a larger unit from Mercedes.
This has never been confirmed though.

In the pic it looks larger. It is very interesting seeing you guys trying to squeeze extra hp out of a 40 year old system keep going I am watching with envy. Do you know if the 6 AN fuel lines are about what they used on the stock 934 back in the day?

If you look at factory 934 Pics. They used the same puny black nylon lines
from the fuel head to the injectors that were used on my 73 RS Lightweight
mechanical injection. The supply lines for the pumps etc were the same stock
rubber coated lines also.

That's good to know I think in the world of fluid dynamics the stock 3/8 lines are probably just fine for the kind of hp I want to produce. I am going to run 1/2 inch through the tunnel and put -8 to -6 adapters on the ends to keep my options open if the E-85 finds me needing more flow. I think the stock accumulator will be going bye bye and I will need a high flow fuel filter to put in its place.

Have any of you CIS guys put a vacuum gauge after the fuel door - before the turbo?

Much respect to you Cole for taking on these projects. I have always liked the cis system and have been asked many times why I don't just convert to efi and ditch this old technology and my answer has always been if it was good enough to win for Porsche it's good enough for me, besides i like mechanical things and cis is just that. Sure we could pick up power and response but the car looses some of it's character in the process. I am following this with great interest .....Ben

Ben:

This is my labor of love and I enjoy every minuite I'm doing it.

I like CIS also, it's old like me !!!! EFI is obviously a better way to go
if you need it and have a spare 10K laying around. I can't afford a big HP
engine and I'm perfectly happy with what I have and if I didn't have CIS
I'd probably get bored.

That is more or less how Corvairs were set-up, and I know that they were prone to throwing their belts . . .

Any updates Cole? I'd hate to see you fall off this planet. If you're still waiting on the TK intercooler then that's understandable!

p.s. Tell your wife and Gracie I said Hello!

Hey Bud hope your are well my friend. That VW is absolutely killer,
and that man defiantly knows what he is doing. The flatfan setup is really
ingenious. I'm way past the point of thinking about a flatfan and would
no longer have the room needed to retrofit one at this point. I would be
the first to say flatfans are about the ultimate in old school cool !!!!!


Ron:

You really made me chuckle, yes, very much like the old Corvair. I
had a service buddy that had a Spider and we broke a belt and got
stranded in the Bruno Desert in Idaho. I've hated Corvairs ever since.


Mikie !!!!!

Great t hear from you, hope all is great with you. I was thinking
about you last week because I have been getting way too much sleep
lately.

Sorry I haven't posted much but I'm just doing clean up and
some odds and ends. I did some rewiring and have 8 pages of
hand written schematics I'm redoing in ink so I can scan and save.
I sent my CIS and WUR out to Larry Fletcher to have it serviced
and dialed in on the flow bench. Chris still has my IC and we
should be seeing it in the next week or two. I tried to hold off on
it as long as I could because Chris has been buried with Linc's
build and the bad parts and coating issues really put him behind.
I should be ready to flame on once it gets here.

Cole

Sorry, you have to be kidding me, they are incredible !!!!!! I never
thought I would ever posses that information. I will never be able to
repay your kindness and will be forever greatfull.

I took a look at your wheel thread and the new Fuchs are absolutely
killer. And you defiantly made the right choice they will be stunning on
the car.


BB935:

You Sir are definatly a man of superior skills, absolutely awsome work.
Please post pics of what you have available it's like looking at lost art !!!!!

From what I have found there were only 31 cars built so if there was a set
with each car that makes what you sent a real Home Run !!!! I'll just buy
some better glasses.

Well I'm back from the dead. I've been dinking around with some of the
small s--- while waiting for the IC.

I was talking to Fairman and decided to take his suggestion and put in an
Innovate MTX-L. great little gadget. Gives you O2 and a nice small display. It
also has output capability and I added an Innovate SSI-4 Output module.
The SSI allows me to monitor RPM, Boost, AFR from the MTX-L, and I added a
pressure transducer on the WUR that will output control pressure to the SSI.
Should end up being a nice little package. The nice thing is the SSI has it's
own 5vdc power supply for your sensors and isolated grounding so you get
good clean signals. You can also hook up your laptop and record test runs for
tuning and download them to files.

MTX-L:




Transducer for control pressure:




Added a pressure gauge after the filter to check fuel system pressure:




Also been getting together some of the body parts.


Front bumper On:




Rear bumper lined with Thermo Tech and fit:






Couldn't find any rockers I liked so we made our own. Final fit before trim
and paint:



Finally have the IC back and on:








I'm ready to check out the new fuel pumps with a little gas and check for leaks.
I'll be putting the CIS back in soon and then it's waiting for a piece of IC pipe and ckecking out the MSD for some spark.

Cole
