Re: [DML] delorean turbo question

["content22207" <brobertson@xxxxxxxxxxxx>]

I've had excellent results running a richer overall fuel mixture on
what is basically the same engine (8.5:1 compression). Is especially
noticeable at lower RPM's. Note that I have no catalytic converters to
be affected.

(Don't even think about igniting a carburetion flame war -- Renault
cleaned the 2.8L odd fire clock with a dual carb'd setup on the A310:
160 max HP, albeit at 9.5:1 compression).

Speaking of which: all super/turbo charging does is basically yield
the same results as simply increasing compression of normal aspiration. 

Regarding the exhaust system: If you route it UNDER the rear frame
extensions, rather than trying to squeeze it BETWEEN them, space is
opened up for all sorts of options, especially if you don't use a
muffler across the front of the engine. My engine compartment now
looks absolutely anemic next to a factory configuration.
