[DML] Re: More performance?

["Harold McElraft" <hmcelraft@xxxxxxx>]

How many people have tried to up the HP on DeLoreans? Generally 
speaking, whatever you do will lead to compromises in looks, 
durability, emissions, and drivability. Today's 3.0L engines can 
yield over 200 hp but what is doing it? The HP is attained through 
improvements in ignition, fuel delivery, variable timing, more 
valves per cylinder, etc. A typical 200+hp 3.0L today has complete 
electronic ignition with a central processor monitoring crankshaft 
position, anti knock sensors, throttle position, engine temperature, 
air temperature, air flow, atmospheric pressure, fuel system 
integrity and exhaust temperature. Fuel systems are extremely 
precise and uniform in fuel delivery. All this is being evaluated 
and constantly adjusted at processor speeds of 300 MHz or more. This 
is certainly no match for our 2.9L D V6.

That said however, the DeLorean V6 can, in my opinion, be improved 
best by improving the spark delivery. The stock mechanical spark 
system fails to deliver precise spark for efficient burn above 5,000 
RPM which is typical for mechanical spark systems. Over the years 
several dyno tests people have done including an extensive one done 
by DeLorean One on a twin turbo engine of Ed Bernstein's that 
showed, in addition to fuel delivery for the twin turbos, spark 
could be improved. Improvements in the spark will, I believe, 
deliver some key performance enhancements. Short of changing to a 
complete electronic spark I have been monitoring DMCH's Nology 
Hotwires upgrade and also John Hervey's ignition enhancements. I 
have decided to try out DMCH. As soon as the weather breaks here in 
NJ (think warmer) I am going to install a kit. My engine mechanical 
is completely OEM. I have nearly 40,000 miles on the current tune-up 
so I might not be doing a fair before and after comparison but by 
the time I get to PF I should have enough miles on it to know how it 
is going to behave.
