[DML] Re: Dyno Results - Grand National Delorean

["d_rex_2002" <rich@xxxxxxxxxxxxxxxxx>]

How much Horse Power? How much Torque?  These are two
questions that come up often when people as discussing all
configurations of engine setups in the Delorean, from stock,
to single turbo, to twin turbo, to all varieties of engine swaps.

Most of us have seen the engine dyno numbers on the DMCH
upgraded engine but for some people, like myself, the proof is
in the RWHP (Rear Wheel Horse Power) when the enigine is
tested, fully installed in a car, putting the power to the ground.

Today was that day for the Grand National powered Delorean
at the Buick/GN club Spring Dyno Technical Session, April 17.
A few club members saw my car at the World of Wheels show
a few months ago and they asked me to join their club.

To see more details of my setup, 3.8L Turbo with stock 5-speed
Delorean transmission, check www.DeloreanMotorCars.com
under the High HP Delorean link.  I did this Dyno test with stock
Delorean wheels and tires sizes.

Although I am not "done" tweeking the Grand National Delorean,
including replacement of a malfunctioning intermittent coil pack,
I REALLY wanted to know what kind of potential the engine had,
since no significant changes have been made in about a year.

The Results:

Really nice sunny, spring day, 75 degrees and 75% humidity.
DynoJet Dyno and DynoJet Performance Evaluation Program.
My Delorean tested in 4th gear, from 2500 RPM to 5000 RPM.
Coil pack "cut out" consistently at 4100 RPM (need to fix that)

Peak power delivery observed between 3200 - 4700 RPM at a
near flat, very slight curve, trailing off quickly after 4750 RPM

Rounded Up Performance Numbers  165 RWHP,  255 RWT

Actual Max Rear Wheel Horse Power   164.79 @ 4300 RPM
Actual Max Rear Wheel Torque  254.94 @ 4600 RPM

For some direct comparisions, check out a variety of engines
tested on the Dyno "at the rear wheels" at the link below:

I'm looking forward to see how I do after I replace the coil pack
and maybe upgrade to a programmed chip.  Should be good.

Later,
Rich W.
