Subject: Order of the dyno testing...
Content-Type: text/plain; charset="us-ascii"
Order of the dyno testing:
After thinking about the way to test the engine to show what different items
will do for the Wasserboxer engine. The test needs to be meaningful, but not
take a lot of time to change parts out.
Determine a Base line: The base line will be a stock Vanagon.
The base line for my set up will be as follows:
(The improvements that are too involved to change for testing will be the
base line.)
Modified Cam, modified heads, ceramic coatings, Walker Super turbo muffler,
stock exhaust, modified throttle body, stock air filter, single tip Bosch
platinum plugs, non-synthetic oil: 20Wx50 oil, stock rocker arms, steel push
rods, standard fuel pressure regulator, non-synthetic transmission oil,
lightened flywheel.
Tuning step one:
(Listed only parts changed from above) Synthetic oil: What would be best
weight and brand? Will only test one except Redline (it will be last)
COST $25
K&N air filter. Cost @$50 (Lifetime filter: clean at 50,000 miles)
Bosch Quad tip plugs $4.50 each (My cost from local FLAPS, been shopping
there for 19 years)
Red Line synthetic MTL cost $24 to $32.
Step two:
1.25 ratio rockers @$150
Cromoly cut to fit push rods @$44 set
Step three:
Red Line Synthetic engine oil 5Wx10
(5 quarts at $8.50= 42.50, Lasts 10,000 miles / 3 normal changes = $14.67
actual cost per 3333 miles or normal oil change)
Step four:
Adjustable dual-diaphragm fuel pressure regulator, cost @$80. (Increased
vacuum response to changed cam duration and faster response to engine needs
than stock regulator. Because the engine can rev faster the FI pressure needs
to be able to respond faster to engine needs).
Also increase fuel pressure a few pounds say from stock 36 to 38 to 39, and
to see the results.
Advance timing a degree or two.
My transmission should be back here in about one and a half weeks. UPS
dropped it and damaged it, so it had to be returned. The plus side is that
the stock .483 R&P will be changed to a .457 R&P and fifth changed from the
.70 to a stock .85. Now it will be better suited to the changes to the
engine.
A date for the dyno testing could be the 13th or 20th of November. As many
list members are welcome to show up. We could do a cookout or something
during the dyno testing, maybe others would want to know what there is their
HP.

I could add each part and run the dyno test, but that would take more time.
Each hour is $100 (I am planning on two now), I do not know how long the test
would be for the results of each part? I have never done this kind of testing
If the consensus is: each item separate, then CD price MIGHT need to increase
some (This is also dependent on the number of people actually buying the CD).
Other ideas about testing?
