When I was at the 2001 SEDOC meet they were giving test drives of the upgraded cars. The exhaust note at idle is incredible sounding... it literally sounds like a v8 burble. But under hard acceleration the car sounded like a chainsaw on crack... LOL. I know I'll be getting the exhaust system as soon as my budget allows though. I've got a good excuse to splurge since I need new manifold gaskets anyways... haha!

Subject: RE: Speedo Angle Drive Question
Don, regarding one-piece speedo cables which eliminate the lambda counter - a
few years ago I had some made up but there was little interest in them. I
still have one left if you are interested, for $59.95 plus $3.85 Priority
postage. It is braided stainless steel, Teflon lined, just like my regular
custom cables.
Also, to the person who asked about eliminating the angle drive altogether,
that would be difficult for several reasons. One, the nut that holds the angle
drive also retains the spindle in the steering upright/knuckle. Not something
you want to replace with a pot-metal speedo cable nut. Second, there is not
enough clearance for a single cable to exit the spindle and point back to the
firewall. But mainly, the angle drive is not a 1:1 ratio so without it your
speedo would no longer be accurate.

Subject: Re: DMC Houston Performance
I spent about a week at the DMC Houston center while my car had
about $10,000 of repairs/upgrades made (not exhaust or engine
performance-related...just things that needed fixing or that
improved daily-driver reliability). I was able to listen to (and
drive) two individual cars that sported the performance exhaust that
DMC Houston sells. BTW, in each of these cars, the whole DMC
Houston engine upgrade had been done, not just the exhaust system
upgrade.
The overall effect was that the exhaust had a very nice deep,
throaty tone. Another thing I liked was the effect of the
performance cam upgrade on the exhaust sound (a loping, 60's muscle
car sound). I definitely liked the tone of the new exhaust, and
prefer it over the stock quiet system. It was louder (than stock)
inside the passenger compartment, but you could hold a conversation
over it unless you were really stomping the accelerator. Remember
that you will be listening to a 6-cylinder engine, not an 8-cylinder
engine that I associate with 60's muscle cars; the effect is very
similar but not exactly identical. It's definitely cool, though.
I have also decided, because I liked the way the new exhaust sounded
to me, that eventually I will get the new exhaust system, whether or
not I go with any other engine upgrades.

If you have just the exhaust how does it sound and does it make much

Subject: RE: rough running
I found a rotting and loose vacuum hose on the UVO (unidentified vacuum
object) on the distributer. I stuck it back on and it's slightly better.
So... I need to order a bunch of that little stuff and start replacing a lot
of it, probably. What is the OD/ID of our vacuum hose? Does anyone offer
nice pretty hoses?
For anyone with the braided metal-exterior hose (sleeved or otherwise): how
hard is it to keep clean? It would look nice clean, but I imagine would get
dirty-ugly quick.

I went home sick the other day and ended up leaving the car out all night,
which is unusual for me. It's out all day through all kinds of weather, but
never all night.
The very next day (Tuesday) it started running rough. It's VERY noticeable
with the A/C on, not so bad with it off. Cold starts are much worse than
warmed up.
Gas smell can be kind of strong after the cold starts.
About a month ago I did the distributer cap, rotor, plugs, wires, o2 sensor,

It's very hot and humid here. I'm thinking condensation and grounds.
So I'll start with the ground points tonight. Any other ideas?

Subject: Angle Drive Cable Windings
Nope: mine is wound like a left handed bolt -- "threads" angle from
right front to left rear. After reading replacement procedure for this
cable, am convinced to try splicing a new end on first. Couldn't work
any worse...
Have test fitted tension spring I'd like to use in splice. Is wound in
other direction, so threads on without too much difficulty, but
catches cut loose ends of outer cable windings when removed (counter
clockwise -- same direction as wheel rotation). That must be what
wheel disc did (something compromised outer windings and at 80 mph
wheel did rest).

Bill
Are you sure that the cable was not a replacement itself. Once upon
a time I was going to replace the inner cable because of a crimp -
so, when I got ready to put it in I noticed the new one was in fact
wound the wrong way - the original one was not. After some checking
I discovered that they come both ways depending on the application
(I had gotten a universal cable that comes with a cute plastic end
with some epoxy to hold it in place). I could not find a universal
that was wound the correct way and eventually went with the OEM
replacement, which was wound the correct direction.

Subject: Re: Eliminating Angle Drive
My idea for eliminating the angle drive would be to remove the angle
drive and have a photo-optic transducer in it's place driven by the
square shaft that used to turn the angle drive. This would make the
speedo electronic to interface with a digital dashboard like a Dakota.
You would lose the Lambda counter but I am sure you could duplicate it
with a digital counter in the speedo and light a light as a reminder.
Of course it is cheaper to just stay with the stock set-up even though
the angle drive is pricey. Make sure you have the lower cable support
bracket to keep the cable from hanging and everything should last a
long time if you lubricate it once in a while.

Subject: Receiver wiring harness equivalent
I've finally decided to break down and replace the stereo in my daily-
driver car with something from the current century.
I've purchased from Crutchfield before, and one thing they offer as a
freebie is a wiring harness connector that can be used to connect the
new receiver into the existing harness without having to hack
everything to bits. They have a selection of over 100 such little
connector sets to choose from.
Alas, the DeLorean is not listed as a recognized vehicle (not an
unusual occurrence for most DeLorean owners), so which wiring harness
freebie to take advantage of to splice into the existing harness is
not obvious.
Does anyone know whether the wiring harness connector for the in-dash
recceiver for the '83 model (ASI receiver) was also used in any
mainstream vehicle? Of the 100+ solutions offered, it would be
convenient if one of them had a compatible connector that could be
used to avoid hacking up the DMC's wiring harness.

Subject: Spark advance (UVO?!) hose
Unidentified Vacuum Object is the spark advance diaphragm. Moves rotor
button farther from cylinder top at higher RPM's.
If my R30 is representative, 3/16" hose works excellent. You don't
want pretty hose -- you want tough hose. Environment is harsh in
normal engine compartment. In DeLo is positively brutal. HOT. No air
circulation. If you intend to drive the car, get the toughest 3/16"
hose available.
For years I have used fuel line hose in vacuum applications. Holds up
excellent. IMHO looks pretty good too (I'll repost larger pic of upper
air assembly to #5939's photo album. That's my spark advance takeoff,
using fuel line hose, just before throttle plates -- R30 configured a
little differently than stock DeLorean).
Speaking of which: you should not feel any vacuum in line to spark
advance diaphragm at idle. Stock DeLo uses solenoid to shut off until
throttle plates open. If you've got vacuum to diaphragm at idle,
engine is horribly over advanced. Won't really idle unless you over
retard distributor body or over enrich fuel mixture, either of which
will kill performance as throttle plates open.
Note also stock DeLo has vacuum lines to control pressure regulator
and a delay valve, all of which must work properly -- as soon as
throttle plates open full vacuum is shot to spark advance diaphragm.
Is one heck of a jump in ignition time. At previous fuel mixture
you'll get predetonation (spark knock/valve clatter). To compensate
DeLo briefly enriches fuel mixture at CPR . By the time delay valve
equalizes vacuum in the CPR, vacuum spike at spark advance diaphragm
is over.
Complicated, eh?
IMHO whole arrangement can be simplified greatly (actually, that's
what Renault did with R30):
1) Remove vacuum from CPR. Then becomes warm up regulator only.
2) Move spark advance before throttle plates (like a carburetor). Will
get moderate advance only in time with throttle plate action.
BTW: Extent of my vacuum system is:
-Direct line from upper air assembly to spark advance
-Big line from passenger intake rail to vacuum canister and front of
car (plus little line back to heater core shutoff valve)
-Auxiliary air valve (for fast idle) engineered from BMW between upper
air assembly and cold start tube (I moved from original installation
at driver intake rail for balance)
That's it. Beautifully simple.

Why can't the small cable be made from a flexable solid material. Why does
it have to be like the bicycle cable with squared and soldered ends.Surley
it doesn't have to move over an 1/8" or less.

Are you sure that the cable was not a replacement itself. Once upon
a time I was going to replace the inner cable because of a crimp -
so, when I got ready to put it in I noticed the new one was in fact
wound the wrong way - the original one was not. After some checking
I discovered that they come both ways depending on the application
(I had gotten a universal cable that comes with a cute plastic end
with some epoxy to hold it in place). I could not find a universal
that was wound the correct way and eventually went with the OEM
replacement, which was wound the correct direction.

Subject: Replacement Angle Drive (For Right Hand Drive?)
Could well be. Entire engine is a replacement, so I wouldn't put it
past PO.
Does anyone know if replacement angle drives were once offered with
cables wound in wrong direction?
My housing is labeled "Smith Motor Accessories Ltd, England" Part
#862401/11.
Hey! Wait a minute! If my angle drive was designed for a speedo on
RIGHT side of car (driven by PASSENGER wheel), would be wound
correctly. Do I have a right hand drive angle drive?
BTW: Am having difficult time locating cable with 1/8" square end.
Even struck out at local truck repair facility. Have a backup idea
that should generate untold controversy... (watch this space...)

Subject: Re: Re: Eliminating Angle Drive
While we're on the subject of eliminating the angle
drive altogether and going to an electric speedo, why
not use the original speedo drive point on the
transmission? An electronic sensor that's just
counting teeth on a trigger wheel wouldn't care which
direction it's rotating. Would it?
This was the first I'd heard of there being an unused
speedo output on the tranny. Can someone point me to
it? (Anybody have a picture?) I will be using an
electronic speedo on 02650 and would rather mount the
sending unit to the tranny rather than the front
spindle. I'll happily post the process/results on the
website.
Thanks

Subject: Re: Eliminating Angle Drive
It's a little more complicated than that. On the side of the trans
(actually the differential housing) there is what appears to be a
freeze plug. Immediately behind that is the back side of the ring
gear (i.e. the side without teeth). It would be possible to put some
kind of sensor in that hole, but the hairy part is that you'd have to
put something to count (teeth, magnets, etc) on the ring gear
carrier. There is nothing in place.
This is very similar to electronic tach applications used in other
cars, BMW for example uses a pickup on the diff housing to read the
ring gear rotation.
In the "other" application of the DMC Renault trans recall that the
ring gear is flipped over. I suppose that there is something
installed in that application to drive the speedo, but I've never
taken apart a Fuego trans to see what.
Honestly it would be easier to put a transducer on one of the inner
CV joints (like many aftermarket cruise controls).

Probably beat you to it.......When I got my car, I saw that the prior
owner had replaced that short piece of cable with a hunk of 1/8"
welding rod cut and ground to the right dimensions. Actually worked
pretty well until the housing of the angle drive broke. I had no idea
that this was not the original design until the new one arrived.
