Subject: Re: Re: Fuel Octane

I agree that 89 isn't what would be considered high octane. I can't see
any
problem using that in a combustion chamber designed for "regular" fuel.
I'm
a bit curious though why you're running the spark retarded 3 degrees. The
DeLorean spec calls for 13 degrees advanced and 10 is 3 degrees closer to
top dead center. With 89 octane fuel and your hotter ignition system why
not try
advancing to 15 degrees and see if you notice any pinging. If not, you'll
see a bit less fuel consumption and maybe a bit more power. As seasonal
temps go up you may begin to experiance some pre-detonation though so it's
a "play it by ear" thing.

Andy,
I entirely agree, it is the same reason I just purchased mine. I am in the
process of doing a complete engine overhaul. The whole engine is getting
torn down, all gaskets, O-rings, etc. are being replaced as well as the
water pump, air pivot switch, bearings, etc to make sure the engine is
completely tight. The air bleeder kit will help be completely bleed the
system once it is all back together.

If you are buying it because you are accumulating air in your system on a
consistent basis, then that indicates a bigger problem that should
probably
be addressed at some point.

Subject: fan over-ride switch

On my last DeLorean, years ago I installed an over-ride switch to manually
turn on the fans if needed. I cannot locate any paperwork or diagram how I
connected what to where. I recall that the wires were only in the cockpit
area, non of them going directly to the fans themselves.
Can anyone assist? Send me a sketch?

Took the car out of storage and drove it yesterday for the first time this
year. Started on the 1st turn. When they are fixed correctly, what a great
feeling!!! Temp gauge stayed between the lines and the air works!
