ALLPAR.COM can help you with loads
of information about your Mopar!
Here are some links of both discussions and articles written by Mike
Holler. He has some really interesting ideas regarding how to make
more power without radical modifications.
http://www.allpar.com/fix/holler/
The
2.2 and 2.5 scraper designs have been updated. The scraper
substructure is constructed from thinner gauge steel that is
approximately the thickness of a normal compressed gasket. The opposite side spacer has been
altered to become a scraper which operates on the downstroke versus
the upstroke for the scraper plate on the opposite side -- so now
you have a dual scraper system. A TeflonŽ version is also
available. $69.95
Please let us
know what engine you have, for example: early 2.2 NA, late 2.2 NA
common, block , 2.5 NA, 2.2 T with cast crankshaft, 2.2 T with
forged crankshaft, 2.2 T common block with forged crankshaft - NO
balance shaft assembly, 2.2 T common block with forged crankshaft
and balance shafts (stock T3 & T4), 2.5 T, 2.5 T - balance shaft
assembly removed.
FWD Performance is your
source for 2.2 and 2.5 Mopar performance!
Here is an
extremely informative article covering a 2.2 turbo engine rebuild by
Bob O'Neill. Pay particular attention to the oil pump outlet
modification and the suggestions on bearing clearances.
NEW!
There is now a dual windage tray and
baffles setup for the 2.2 and common block 2.2 and 2.5 engines with
balance shafts removed. The
setup includes oil baffles with trap doors for the sump and piston
bay segregation baffles that help to prevent windage from traveling
along the crank -- this is technology you see in Winston Cup
engines, for example. A special oil port block-off washer is
included for people that have not already removed their balance
shafts.The pictures below illustrate the setup. The setup runs
$399.95. The setup
will work with existing scrapers supplied by us or Gary Donovan.
What you will need to supply is a 2.2 turbo or 89-91 2.5 oil pan and a 2.2 oil
pickup tube as pictured below.

Neon 2.0
-- Also known as 420A, S4RE
or D4RE:
NEW!
Dual scraper that works on both the up and down stroke
$79.95
TeflonŽ
version $100 additional
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dual-windage tray setups
with oil pan baffles and trap doors for the Neon 2.0:
Note these pictures do not show the dual
scraper that now comes with the setup
 The
stock 2.0 engine in the "Cloud cars" (sohc and dohc -- often
referred to as the 420A block or S4RE or D4RE) lacks a windage tray
or any oil baffling in the stock pan*.
Many people have written to us and commented in forums that they
experience drops in oil pressure when driving enthusiastically.
The stock oil pan is actually a high quality piece it just
needs some oil control hardware.
We now make a dual-windage tray for this engine with louvers and lower
baffles with swinging doors. (See above pictures...) It attaches to a modified crank scraper
(steel or TeflonŽ) framework that has bridges across the crankcase.
The dual-windage tray has a top louvered section that can be
adjusted to closely follow the rotating assembly. Underneath this
louvered tray is a second tray with offset drain slots. The
trays are separated by a gap of 4.5mm. These drainage holes and gap
allow the top louvers to quickly direct the oil out of the path of
the rotating assembly. Conversely they also help to isolate the
rotating assembly from splashing sump oil that would otherwise come
through the louvers. The two lower oil baffles have three
independent swinging trap doors that help to keep oil around the
pump pickup during hard turns.
Another advanced feature are the four attachment baffles that hold
the windage tray assembly to the scraper frame. These are solid
plates that help to segregate the piston bays. Why? When one area of
the crank has a high concentration of oil in the windage cloud the
crank acts like a propeller and distributes this oil along its
length. By closing this path off the oil cloud is instead focused
into the tray louvers and of course the crank scraper. You can see
this type of feature in the Ford Zetec sump and other racing
engines.
Lastly, as you can see in the above pictures,
there is plenty of clearance for the oil dipstick and the dipstick
readings are unchanged.
The windage tray and baffles are $309.95 in
steel -- remember this includes the dual scraper. The dual scraper is
also available in a TeflonŽ version.
The dual steel scraper alone is $79.95.
*Important!
There is a steel and aluminum stock Neon pan as well as another
steel pan for this engine when installed in DSM vehicles like the
Eclipse. Each of these pans has a very different internal
shape and requires a different set of lower baffles and trap doors.
You must let us know which pan you will be using.
~~~~~~~~~~~~~
Early 2.4
as in Stratus,
late 2.4 as in P.T. Cruiser, 2.4T (as in SRT):
NEW! Now a dual scraper design for engines with balance
shafts in place. $89.95
The special joints allow for a gas tight seal. RTV silicone
gasket maker should be used to seal the scraper to the block and
pan.
This scraper is a replacement for the
stock pan gasket. The SRT4 and P.T. Cruiser Turbo gasket already has a
scraper built into it but this scraper offers far more coverage of the rotating
assembly. It has acceleration trap doors to help stop oil from climbing
the rear of the pan -- great for drag racers. During normal
operation the doors allow draining of oil from the side of the block
that settles on top of the scraper.
The difference between the early and late engines is the oil pump
and this changes the oil pan flange. We have versions for both
the early and late engines or whatever motor you create in between!
~~~~~~~~~~~~~~
For 2.4 owners that removed their balance shafts we now have a
dual-louvered windage tray with baffles and trap
doors available for the Early and Late 2.4
as used in the Neon and PT Cruiser, among other vehicles (see pics
below and additional info in the Dodge SRT4 section). It attaches to a modified standard steel or TeflonŽ
(Patent Pending) scraper framework. It has interior walls that help to segregate the
piston bays. This helps to inhibit the travel of excess oil in
a windage cloud from one area of the crank to another. The
windage tray, baffle and scraper setup is $359.95. You get to keep your high quality cast
OEM aluminum sump but with better oil control.
Also, you will get our special block-off washer to use to cover
the oil feed line to the balance shafts.
Latest updates!
Now dyno tested and proven! This
setup has a total of 5 independent trap doors -- two in the sump to
control oil movement from side to side and three on the underside of
the scraper frame. These three close under hard acceleration
when oil may try to climb the backside of the block. Ideal for
drag racing! In the front is a shelf that helps block oil from
climbing the frontside of the block under heavy braking. Ideal
for road racing! A dipstick guide tube makes installation even
easier. Directional screening now covers the louver openings on the
top windage tray.
New!
The setup now includes a dual scraper
We also have windage tray kits to fit
the various strap kits being offered: $409.95 for steel scraper kit;
Teflon $100 additional
Note: the baffle designs on all models
have been updated with a Teflon collar for the pickup tube.

Windage System for SRT-4
I felt it appropriate to share my initial
results after installing your Windage System for the SRT-4.
Unfortunately, I am not a lab, and it was not the only change made.
However, the other changes should have had little difference on
performance. I put in a new set of plugs and wires, though there was
no indication of a problem with spark, and could not tell any
noticeable difference in the car from doing so. I also replaced the
3" Mandrel bent exhaust with a similar 3" Mandrel bent exhaust,
which removed the muffler. (This could have gained 5-7 hp). The only
other real change made, was to put your windage system into a car
that already had the balance shafts removed. We carried it to a 1/8
mile track. The previous trap speeds on the car were 87.45 mph in
the 1/8. The new trap speed was 92.95, or about 40-45 hp of
increase. Let's just say, I'd have been very happy with half that
improvement, especially for the money spent. I'd recommend that
system for anyone who wants to make power from their SRT-4!

Some customers like to use the special oil pump pickup made by
Darrell Cox Racing.

No Problem! We have a special baffle designed just for this
application and it doesn't cost any extra if you specify it when you
order your setup, otherwise it is only $35.00:
Some racers are using the early 2.4 pan and oil pump in later
vehicles since it is easier to run a remote filter and cooler with
that setup. If you are using the early 2.4 pickup
please let us know because we also have a special baffle just for
that pickup.

There are a number of variants.
4-Bolt 6G72:
The dual scrapers ($74.95) work on both the up and down stroke. The
tight clearances of the girdle to the inside of the pan dictate that
the scrapers have varying coverage from the first through third
bays. The scrapers are made from 18 gauge steel and are to be
sealed with RTV silicone gasket material. The windage tray
runs $199.95. Note there is another design for two bolt
blocks -- see below.

Wayne Kasel was incredibly helpful in the
development of these parts. He supplies high performance parts
for the 3000GT and Dodge Stealth using both the 4-bolt and 2-bolt
engines.

Below -- the main bolts are installed and torqued and then the
screening insert is installed.
(Girdle is not included)
  
The windage tray covers the entire rotating assembly with
directional screening. The screening strips oil away from the
rotating assembly and allows it to pass through to drain to the
sump. Simultaneously the screening shields draining oil on the
floor of the pan from being hit by high speed droplets of oil and
aerated:

dyno curves began diverging at 2800-2900 rpm. He did a
baseline pull with a CRE girdle and Milodon louvered windage tray in
place. He cannot recommend the CRE girdle highly enough, by
the way.

This picture shows the
first test pattern fitted to the block:
Kevin, this is just a note to let you know about the results of
installing the crank scraper on my 440 Chrysler drag car. I won the
first time out with it on the car and the oil pressure has NEVER!! been
this stable while racing, or hard on the brakes. Plus, the car ran the
best E.T. ever in weather that was less than ideal. I can hardly wait to
give it a little tuning.
Thanks for working with me,

NEW! Rear windage
tray for big blocks
During hard acceleration in the big block the oil rushes to the back of the
motor where it can then easily splash up and hit the rotating assembly.
This robs your engine of valuable horsepower and can allow the rear bay rings to
become overloaded with oil -- a prime cause of detonation.
The small tray we make is designed to work with most existing
windage trays and complements the dual crank scraper we manufacture.
It closely hugs the rear most counterweight and helps to shield it
from oil that reaches the back section of the pan. It
incorporates an adjustable scraper to quickly eject any oil that does enter.
The ovoid drain hole matches up to a hole in the scraper pattern;
a small extension shields that hole and directs the ejected oil to
the side of the pan. This extension can be trimmed to fit
within existing windage trays:
Rear of stock pan
$49.95
LA: 273, 318,

Dual scraper design works on
both the down stroke and up stroke of the engine! $69.95
Teflon version for $169.95:
New downstroke LA scraper with shield and
screening. This version is pan and
stroke specific -- also it is important to know what main caps you
are running. If your pan is similar in design it can be
adjusted by the owner using basic sheet metal hand tools.
Designs for additional pans will be done with owner's pan being
shipped to shop for fitting or detailed pictures being provided.
This design reaches into the 1st quadrant ATDC and directs oil into
a shielded area. This area has directional screening within it
to slow the oil and then protect it as it travels to the sump floor.
The louvers are adjustable. This price is for the downstroke
scraper only $199.95
