370 inj's, Gov.springkit, AFC sprgkit,WOW!

I just returned home from vacation
and the Scheid Diesel Rally. I told
Koa Man, A-bomb, and David B. that I
would post some "results" so.....
here we go.......

Prior to the rally, Scheid Diesel
installed the 370 Diamond B injectors
in my truck along with the governor
spring kit and the AFC spring kit.
For those of you that don't remember,
I previously had posted about a "flat
spot" or "lag" on the low end after
having a new TC and valve body
installed. Well I am here to tell
you that the flat spot is GONE!!

"Koa Man" if you read this post
I sincerely want you to know how
much I appreciate all your input
in helping me decide to install
the 370 injectors.

Now for the "baseline" results
of all these modifications.

DYNO H.P. BEFORE MODS- 224
DYNO TORQUE BEFORE MODS-625

DYNO H.P. AFTER MODS- 381
DYNO H.P. AFTER MODS- 1069

0-60 time BEFORE MODS- 8.92
0-60 time AFTER MODS - 6.75

Top Speed BEFORE MODS- 104MPH
Top Speed AFTER MODS - 118MPH

(Note: I had planned to run
the truck on the drag strip at
the Scheid Rally on Sunday but
because of rain they had to
cancel this. I will do this
locally as soon as possible.)

SMOKE- Before the modifications
I had black smoke off the line
but then it would clear up. If
I accelerated at 60-80 it would
smoke until I let off the throttle.
NOW, I seem to have less black
smoke on take-off but when I push
the throttle hard between 60-80
it seems no worse than before.
Loaded and level takeoffs, smoke
is acceptable.

EGT'S- The EGT'S don't seem
any worse than they did before the
modifications. The first run that
I took from Scheid Diesel's Terre
Haute shop, I punched it all the
way to the floor and held it there
until I got to 115 MPH! The EGT
gauge was reading 1215 degrees.
That is with the probe in the
exhaust manifold. Air temp. that
day was about 82 degrees. This run
was witnessed by John Pezan from
Scheid Diesel and my wife who was
sitting in the back seat!! On my
way home the air temperatures were
slightly higher than they were in
Indiana, and I pushed the truck on
some 4-5% grades on I-77 in VA.
and one time I did have to let off
some as the EGT was creeping above
1350!

The difference in the throttle
response is VERY noticeable! When
I accelerate now the truck will
continue to pull up to 3400 RPM.
Before the modifications to the
pump, the governor began cutting
fuel off at about 2600 RPM. Now,
it goes right past that and on top
end I go past my old top speed of
104 FAST and the engine continues
to pull hard to it's new top speed.

I am very happy with the results
of all these modifications. I want
to sincerely thank Dan Scheid, and
his following staff of people at
Scheid Diesel,(Terre Haute) for
everything they did for me: John
Pezan (J.P.), John Wood, Kent,
Lloyd, Larry.


Koa Man, Piers, Joe Donnelly:
Thanks for the help on the advice
of the 370 Diamond B injectors!

The "flat spot" is GONE!!!!!!!
