Tar can easily be dissolved and removed with mineral spirits or lighter 
fluid; neither will harm the finish. Both are available at the paint store; 
lighter fluid is also called naphtha.

This discussion is better off continuing over on the BTTF newslist.

Bob,

After seeing the same information on the DVD a few months ago, I did
contact Stephen Clark (BTTF.com) to see if he had someone to contact
about verifying this info.  He recommended trying a chat session with
Bob Gale scheduled earlier this year, but I could not get through
with the question or he just ran out of time to answer every request.
I am still pursuing other contacts, with no verifiable details yet.

As far as identifying the possible Porsche engines, the field does
narrow quickly based upon the production periods of the movies.

As for choice of Porsche engines, the flat six of the 911 models
would have been a real challenge to fit in a Delorean without some
substantial modifications to the engine cradle area.  The early,
normally aspirated 944 engines (4 cylinders) put out about the same
amount of HP as the stock PRV V6, at 135HP through 1985.5 models.
While the 944 Turbo engines put out substantially more HP, these
engines were first offered in 1986 in the US, so the only Porsche
Turbo 4 available for the first movie would be the 924 Turbo and
that model made less HP than the normally aspirated early 944. 
However, Turbo engine transplants also imply complicated exhausts.

Although I would have to listen to the details again to be sure, but
on the DVD, I think Bob and Bob alluded to more use of the Porsche
engines in the second and third movies, allowing the possibility of
using the later model 944 engines, either the 16 valve 944S engine
or the even more powerful 944 S2, 16 vavle, 3.0 Liter 4 cylinder.
The 944S is just shy of 190 HP, while the 944 S2 makes 210 HP.

In any case, the engine sound used in the BTTF movies does not appear
to be a Porsche Turbo engine (they all have a distinct Turbo whine),
so it is much more likely that a modified 944 engine was used, for an
easier install or the air cooled, flat six was engineered into the D.

Until we find out from the BTTF gear head in charge, this topic will
probably keep us guessing for a while longer.

Later,
Rich W.
