Subject: Re: Venting outside air over engine

Hot is a relative term. The engine NEEDS to run hot to run
effieciently and all of the internal clearances are set so when the
metal of the motor is at operating temperature everything expands to
just the right size. To really know if you are running hot you need to
measure the temperature. Start off with calibrating the temperature
gauge. If the coolant is 220 then you can guess that the engine is
maybe 10 degrees hotter which would be normal. If it is having
detonation problems the things to look for are:
too lean a fuel mixture
initial timing off
vacuum advance or mechanical advance not working or not working correctly
Too much or too little or the wrong viscosity of oil
Make sure the coolant is a 50/50 mixture of anti-freeze and water
Wrong heat range spark plugs
Loose water pump belt
Bad pressure cap on header bottle
Too low an octane rating of the fuel you use
Finally the cooling system may not be carrying away enough heat from
the engine because of air in the system, blocked hose, bad fan,
plugged up radiater (air OR water side). The motor can live just fine
with the cooling system it has as long as it is working well. The
cooling system needs to be reliable with 15 PSI pressure in it to keep
the coolant from boiling.

<SNIP>

Roof vent adapted for the DeLorean would look really cool! An aftermarket kit 
is available for the Fiero, and I'm sure that it could easily be adapted for the 
DeLorean. Especially if someone was to perhaps intergrate it into the T Panel 
on the roof (kinda like the S7). And I'm sure that it wouldn't be a problem to 
install a snorkle thru the louvers. It's just that with limited visability thru the rear 
as it is, the pipe would hamper a bit of your vision. Maybe if you made the 
bottom section of the pipe clear... But I don't know if that would really even 
help with the angle of the eliptical shaped pipe, or if a strong enough material 
could be made that didn't discolor with the heat.

Then again, I'm just guessing about the visability problem, based upon my 
own observations. I never drove a Fiero (let alone one with that intake), and 
the problem of any visability might be overcome with one of those large, 
curved rearview mirrors for trucks that JC Whitney and others sell. I've had my 
eye on one of those for quite a while.

Try spraying some lubricant on the rubber bushing where the steering
goes through the front bulkhead. You may have to replace the bushing.
You could also try greasing the tie rod ends and ball joints. Make
sure that all of the boots and seals are not cut or torn.

Subject: R30 PRV Timed 10 degrees

According to Martin Gutkowski's PRV buddy, my R30 PRV (Renault) should
be timed 10 degrees. I've tried it at 13, but performance suffers.
Slightly retarded (by DMC standards) timing and a 40,000 volt spark
give me a pretty good jump off the line, even though displacement is
only 2.5 liters. 

Fully agree intake air is important. That's why I'm going to replace
missing fresh air hose. Fords can breathe under the hood. DeLo's can not.

Re: predetonation at full throttle -- I have no provision for fuel
enrichment (other that CPR, which is ambient cold sensitive only). No
Lambda system whatsoever. My CPR has no vacuum chambers. Perhaps one
reason stock DeLo's don't predetonate is extra rich mixture at full
throttle. Other is spark. Not only am I timed later, but my advance is
taken BEFORE throttle plates (by Relault design). Even with the plates
wide open I probably ignite closer to top than stock DeLo's. FWIW, 93
octane took the clatter right out. After dark I went back to 89 no
problem. 5 hours of cloudless sun, continuous A/C (freon on the high
side is HOT), and intake air from under the hood got me (until I threw
a bottle of octane boost in that first tank).

YES! I have been experiencing the exact same problem! And I mean EXACTLY!
I've tried lubricants, gaskets ...you name it but nothing seems to work. It
is especially hard to locate the problem because when everything cools down,
it works just as smooth as silk. But "stiction" is definitely the best
description for this ailment I have heard yet. (just a little sticking and
just a little friction) Arthritis of the steering rack maybe?   I hope
someone out there has a cure because this one has had me stumped for quite a
while.

Subject: ventilation behavior changed

This week I have noticed that when I start my car the ventilation 
flaps have to move back into position and there is a normal sounding 
vacuum hiss until the flaps are into position. I have had the mode 
switch in the Vent position for weeks and I am pretty sure the flaps 
remained in position while the car was off.

Is this the sign of a problem or is it normal and i just never 
noticed before?

Have burned my fingers badly enough to blister on another owner's car

Am just used to big blocks which never break a sweat. PRV is whole

Can't recommend bleed line from thermostat housing enough. Makes
filling the system a snap. Guaranteed no problems (provided thermostat
not stuck). Have also rerouted radiator bleed line to a Tee in heater

I guess it works (my pipe now replaced by hose).

This is interesting from two perspectives. 

First, this has just started to happen in my car. 
When I start it after it has been standing for a day
or longer, I can hear the vent flaps "moving".  No
problems with the air flows and I can move from vent
to a/c to heat and everything works.  Just the darn
noise of the opening or closing of the vents when I
start the car - no hissing, however.

The second perspective is that my car's VIN is just
for off of Adam's.  Coincidence??

Awaiting an answer.

Picture this:
Dual snorkles snaking through the louvers on the
outside portion of the rear window, meeting in a
centralized common airbox directly above the intake...

Could it work, or would the louvers be too weakened by
the cuts you would have to make in them?

<SNIP>

Nope, the louvers were added in for astetic reasons, according to 
several books. JZD was touring the Hethel plant where Lotus was 
building the DMC-12 prototypes, and completing the engineering work. 
While on the tour, JZD saw an Esprit with prototype louvers on the 
back, and decided that the DMC-12 must have them (IMO, I agree).

This is a popular example used quite frequently to describe a common 
difficulty with the engineering of the car: Constant Change. With the 
introduction of rear louvers, Lotus then had to re-engineer the rear 
of the car to accept them. Not bad sounding, except when you take 
into consideration that the rear was already complete, and now needed 
to accept hinges, a latch, side lips, and mounting points for the 
struts, that could handle the stress.

As far as keeping the engine cooler? Who knows. Many people attest to 
this, but I've no idea what they've based this upon. I can tell you 
though that one day when I left work to go home, I noticed a cicada 
crawling around on the edge of my engine cover, below the edge of the 
rear louver. Taking the car up to around 80+mph, the little insect 
was still crawing around. I looking up a couple of seconds later, the 
bug was gone. So who knows if he jumped out, or got sucked out. The 
only real way to know for certain if the louvers really are a benefit 
to the car, is to film one driving fully warmed up with a Infrared 
Camera, and the remove the louvers, to see if there is a difference.

solenoid thatcuts off the advance means that on a Ren engine, timing 
should be set up with the vac disconnected. In reality it doesn't make a 
lot of difference.

Busy playing with timing on a right-hander with Volvo ignition, finding 
its "sweet spot" around 8-9 degrees at idle.

My car also has Bauerle's deflector. The "deflecto-shield" also eliminates gas
fumes/smells from entering the interior.

I have never liked the open hole behind the fans that blows directly 
on the rack. I have had for many years a deflector I got from 
Bauerele Automotive in Radnor, Ohio - 740 595-3348. I trimmed it to 
suit me, but it covers the hole nicely and keeps the blowing heat 
and crud off the rack. It deflects a lot of heat away from the fuel 
tank too. I also serviced the rack with full synthetic oil (75w-90) 
which seems to have done the most to ease the steering effort.

I had DMCH drain and replace the steering rack lubricant and it made all the difference in the world.  But I can't say what the procedure entails.

It seems when the car is cool, the steering performs flawlessly, but as it reaches operating temp on 80 degree days, the steering rack seems to heat up from the radiator and begins to exhibit stiction. The wheel sticks where ever you tend to put. I've pulled the pinion cap and loosened the spring tension on the nylon slider by adding 2 custom paper gaskets to raise the pinion cover, but it only delays the effect and makes the steering a little looser when cold. It's been topped off with 90wt gear oil. Any one else experience this feature? Any suggestions.

Andrie, I pull the coldest air I can from the coolest place I can not being
to concerned about looks. That's from the right rear pontoon. I use a very
simple 2 7/8" flex hose from the bottom of the air filter hosing to the hole
in the pontoon where the hot air valve was.

Has anyone figured out what the air flow is doing around the rear edge of
the T-panel or around the louvers?  I remember reading that lotus added the
louvers for aero reasons.  If you put a scoop in the wrong place it could
actually suck air out of the engine compartment rather than feed it in.

Tom M. over on DMCFourm is making a new T-panel for his car with a scoop on
it, I haven't seen any pictures of it yet.

I will try to get photos this weekend for the lists... for some 
reason I'm not receiving e-mail consistently :(

This is actually the second attempt at the integrated panel/scoop (I 
discovered that a large scoop does not match the subtle lines of the 
DMC12).  This most recent venture matches the style of the car 
perfectly.  For now, the scoop is cosmetic.  My plan in stage 2 is to 
get a brushed or chromed aluminum duct constructed that would take 
the air and direct it onto the engine... similar to the McLaren F1.

With the heads off you are supposed to install blocks with bolts to

Subject: Re: R30 PRV Timed 10 degrees

You misunderstood: I said I was retarded (hmm, why doesn't that sound
right?), not DMC. Stock DeLorean is ALWAYS advanced more than me -- 13
degrees at idle (I idle about 10 because so little vacuum before
throttle plates. No real effect then so I could probably time with
diaphragm connected. And no, diaphragm doesn't have a hole because I
can suck rotor manually). Jumps close to 30 as soon as solenoid kicks
off. That's why DeLo CPR has vacuum chambers. Need to enrich mess out
of mixture the second those plates crack (talk about predetonation!).
My advance is gradual in sync with throttle plates, maxes around 20-25
degrees.

Stock DMC timing MUST cut into performance. Piston spends a lot more
time pushing against explosion than I do. Even though my displacement
is 11% smaller, have no trouble keeping up.

One of the tricks domestic manufacturers used in late '70's to please
government was increasing spark advance. Yields longer burn time in
cylinder, at expense of horsepower. 1977 460 is stickered 17 degrees,
1978 is stickered 20 degrees. Have moved mine 10-15 (don't fully trust
harmonic balancers after 100,000 miles so my final time set by ear).

Wow...I'm glad I didn't push too hard today then. I would have liked 
to have had this info earlier though. I've asked many questions on 
head gasket replacement and it never came up. 

Word is, if I ever want to get that pulley nut off, I'll need an air 
impact gun. Home depot sells one for $28.00 that makes 250 ft lbs of 
torque. Is that enough? Also, if I hook it to a rented compressor 
that makes 150 psi, is that enough to drive the impact gun to 250 ft 
lbs?

And my final question today is: I don't believe I moved the liners 
while I was fiddling around w/the crank pulley today, everything is 
still flush and I didn't see anything move, but if I did shift 
something and I re-assembled the engine, and ran it what would the 
symptoms be? How concerned about this should I be? Do I now have to 
take the engine out and apart?

Does the Saleen S7 have dual intakes that go around the engine
compartment and then meet in the center for the air box? because how
can you be able to see what's behind you if it was in the middle?
The Mclaren F1 doesn't have that problem because of the central driving
position.

I like the idea by Pete with a kind of shaker box like the Mustang Mach
1. That would give
a few extra horses im sure.

What if you reversed the right and left side louvers or some kind of mold
to
direct air from the side of the car into the engine compartment?

just a thought
