Any boost level is safe if you are set up for it.  If you are planning on 
retaining the stock fuel system and not using an intercooler, you should 
be safe with about 6 PSI.  By modifying the existing system to increase 
fuel pressure you can get a more or less reasonable state of fuel delivery 
to match a supercharger.

The DeLorean PRV is (by modern standards) quite low compression.  Even in
the early 90's there were cars stock with 9.0:1 and higher compression
ratios, significantly higher than the DeLorean, running factory-stock
setups with 8 PSI of boost or more.  The difference is that these cars
have modern engine control electronics.  With the necessary fuel and
ignition system modifications you could probably run about as much boost
as you want to without any internal engine modifications.  This may be
more than you want to get into - but I bet you could get 250+ HP out of
the stock engine.

Since you are using a Vortech supercharger it is almost like a belt-driven
turbo.  You probably will have more in common with a turbo install than
with something like a Roots supercharger.

I'd recommend just getting appropriate sized pulleys and not worrying
about any more complex plumbing.

> 2) What timing should I use?

Less than stock? Beyond that this will depend on your power targets, how 
much boost you run and how you modify the fuel/ignition system.

Use the highest octane fuel you can get, especially while you are just
getting the new system dialed in.  Most major cities have somewhere you
can get 100 octane unleaded racing gas.  It's good insurance on an untuned
setup, but you should be able to get by with regular premium once it's set
up.

Methanol injection I would not worry about, you are not building a P-51 
here :)  Water injection is actually a really cheap and easy substitute 
for intercooling, but it's sort of a big hassle because you need to always 
keep the water injection tank full and the pump working, etc.  I think of 
water injection as something that drag racers use, not something for a 
street application.  But you could, it's just a matter of hassle.

> 4) Should I use an aftercooler? (where should I put it and where can 
> I purchase one that will fit?)

If you plan to run more than 6 PSI of boost, you should use one.  Finding 
one and making it fit, well, that's the fun part.  I'd recommend coming up 
with some sort of air scoop (route air in from the nonfunctional side 
scoops?  A snorkel sticking up above the car?  A water intercooler plumbed 
into the engine cooling system?  All sorts of ways you COULD do it...)  As 
far as what to use, just go to the junkyard and look at the turbo cars 
they've got.  It's just sheet metal, you can put it practically anywhere, 
and the intercooler does not care if it is hooked up to a turbo or a 
supercharger.

There's no piggy-back setup for the DeLorean.

If you want big power gains, replacement is the way to do it.  If you are
happy with 6 PSI of boost and ~175 HP, you don't need to.  Just consult
someone who's put in an Island turbo system and make the same fuel
modifications (essentially, this boosts fuel pressure causing more fuel to
be injected based on the same signals to the injectors).  An inexact, but
surprisingly effective, approach.

For big power, switch to a draw-through carburetor setup or (better) to an
aftermarket EFI like a Haltech.

Subject: idle speed regulator

Hi everybody!
I have had my car for 3 years now, I realized this summer that the 
idle speed regulator is disconnected. 
Is this bad?
I plugged it in and the only thing that happend was that the idle 
raised to high.
I diconnected it again and the idle went back to normal.
Does anybody know what the regulator does, should I leave it as it is 
or should I fix it?

Subject: Dealer address, engine number, and other info

Unfortunately, I do NOT have the original window sticker that came with my 
car (though I do have have other goodies). I wanted to create a replica 
window sticker for shows, etc that would be as accurate as possible. My 
question is , is there a way to find out what dealer my D was orginally sold 
from? Also, there ia a spot for port of entry and engine number, is there a 
way to estimate or guess those?? (I believe my car was originally purchased 
in the Boston, MA area. Any help would be appreciated. Thank you.

Subject: Petition: Encourage Curtis & Ulga Bryant

At the DeLorean Club of Ohio (DCO) meeting this past weekend Ken Koncelik shared
that Curtis was thinking of taking a year off by not showing/coming to Pigeon
Forge because people may be tired of looking at his car and/or not wanting to
hear him do a tech session on customizing. Even though customization tastes vary
among owner to owner I know that all of us in the attendance of that meeting like
seeing his car & socializing with him at the shows. I would love to think there
are others who share this thought.

We decided to do an email petition to show Curtis & Ulga that there are owners
who are not tired of seeing their car & want to see them at Pigeon Forge & future
shows to come.

If you share the same sentiments as the DCO simply shoot a reply to me [off
list]. If you wish to send a personal greeting to Curtis & Ulga you may do so.
Since they are not "on-line" I will print out all the replies of support and Ken
will deliver them to the Bryants. Please respond by February 20th.

Just wondering if its anyone on the list.

Subject: Re: Supercharger help

The idea that " boosts fuel pressure causing more fuel
to be injected based on the same signals" may be
correct on more modern MPFI systems, but I do NOT
believe this to be true on our Bosch systems.

There is no "signal" for fuel.  The fuel is regulated
by a mechanical valve which is controlled by air
pushing down on a large disk.   Increasing the fuel
pressure will also increase the resistance of this
valve/plate setup.  The end result will be LESS fuel
to the injector.

The Bosch people I have spoken to claim that a
REDUCTION in fuel pressure will increase the fuel
flow.  (Yes, I know..  this does not seem right at
first glance, but after closer inspection it DOES make
sense.)  I have not verified this myself, but there
are some good books on the Bosch fuel systems.  

Similar fuel systems are used in some high HP
applications (on other engines), so it is likely that
adjustments can be made.

My suggestion for this project (assuming I thought it
was a good idea to add a supercharger) would be to
FIRST replace the antique fuel injection system with a
modern EFI system (multi port) that is able to handle
forced induction.  This alone should buy you a few
ponies because the stock air meter and intake is very
restrictive.

A list member has already done a good job adding EFI
using a commercial system (Good amount of information
on this in the archives).  A cheaper alternative would
be the "MegaSquirt", which is a build it yourself EFI
system.

After the engine is running well with the EFI, then go
ahead and add in your supercharger.

Subject: Re: The Latest Issue of DW from DOA

I've read many negative comments over the past few years on the mailing list 
and abroad about the DOA.  I have been a member myself for 10 years +, and 
have no intention of leaving, as many have done.  I think based on comments 
like this one here...

"Instead of this main audience, the DOA has chosen a TARGET AUDIENCE... 
those who are really more interested in a lifestyle than a car. They want to 
flaunt DeLorean ownership as an experience akin to being a member of an 
elite country club which has an exclusionary membership policy"

... you're forgetting a very important element to the DeLorean and its 
history.  This attitude taken, is what John DeLorean's original intention 
and vision was.  How many times have we heard it, the DeLorean is a car for 
the Bachelor who's made it.  The car went up against Covette, Mercedes, 
Porsche and another elite vehicles.  This car wasn't intended for the 
average Joe.  Just because DeLoreans are more affordable today, than they 
would have been in 1981, doesn't mean they should be treated that way.  It's 
not a right to own a DeLorean, but a privelage.  And the DOA continues to 
respect that ideaology.

My guess is something has happened on the connection to the idlespeed 
thermistor located under the intake manifold, and a previous 
owner/garage has got the idle working on the brass adjustment screws 
rather than go after the source of the problem

Subject: Raffle Car for DeLorean Car Show

At the DeLorean Club of Ohio meeting last Saturday, Ken Koncelik showed 
his raffle car.  It is a work in progress, but I must say that it 
appears he is doing a thorough job.  Based on the work done so far, the 
winner of the raffle will get a very clean, well restored DeLorean.  It 
has lots of fresh paint and powder coating, giving it the appearance of 
a new car (if not better than new).

This car could be a nice introduction to DeLorean ownership for anyone 
who is considering taking the plunge.  It would make a great daily 
driver.  You could drive it to work Monday through Friday, then win 
first prize at your local Saturday night cruise in.

Subject: '82 VINs moved to '83s?

Back in July 1999 there was a thread (copied below) asking whether 
there were some '82 Deloreans which were reclassed as '83 Deloreans. 
It appears that under the headliners were markings indicating an '82 
VIN number that would be exactly 5000 lower than the VIN on the VIN 
plate. Did anyone ever find out why or if this actually occurred. 
Could there have been '82 cars which were pulled out of the 
production line for some reason (quality problems) for example then 
finished in the '83 production year? At that time production was 
slowing, stopping and starting. This may explain why there seems to 
be gaps in the chronology of the VINs and why the month of 
manufacture switch back and forth on a few vehicles.

12000?)

 
  I looked under some headliners on the 82 and 83's we have here in 
the shop:

VIN 11004 JAN 82 - says V11004 on both doors, under the headliner
VIN 16328 AUG 82 - says V11328 on both doors, under the headliner
VIN 16428 AUG 82 - says V11428 on both doors, under the headliner

What I want to know now is, Ray Haug owns 16348 AUG 82 - what's under 
his headliner? Also, Bryan Pearce owns 11529 JAN 82 - the way the 
doors are marked on 16328 and 16428, you'd think his would be 16529, 
not 11529. In fact, Knut, owns 16344, have you ever had your 
headliners off and looked?

The story grows more curious...

Subject: Long Island - New York DeLorean Motor Club

Dear Fellow DeLorean Enthusiast,


I am interested in starting a local Delorean club for the Long Island and
New York area.  Some of the goals of this club would be to:

     1) Socialize with other DeLorean enthusiasts.

     2) Offer technical assistance to members in the group.

     3) Have some more fun with our cars.

If you or anyone you know would be interested in being a part of this
endeavor, please contact me off list at linydmc(at)d2tech.net


Thank you,

Dave & 6530
