john, I have never installed a tonneau cover on my trucks, so can't help
there. But, I received a catalog on Ford truck accs. I must have
ordered it over the 'net, because it has a local cusomizing shop sticker
on the back, but I know I didn't get it from there. Anyway the cover
says 'The authority on Ford pickup truck accessories'. They have a new
Lund hard tonneau for your truck. It looks, like a hard tonneau and a
Lund fastback cab extender combined, plus has a rear wing/spoiler. The
picture shows the whole tonneau lifting up from the rear. This thing
looks REALLY COOL. The cab extender is for real, if you have a rear
slider there's a carpeted shelf and a rear window. It must keep the
full bed capacity length under the shelf, I'm guessing. I will say it
is by no means inexpensive thought at $1400 for short bed and $1500 for
LB!!!! I'm sure you didn't have that kind of money in mind, but if
you're interested let me know, I'll at least give you the # to my local
shop, maybe they can help.
Stupid question time -
Where is the plug for the block heater?

Jim, thru reading I see that K&N says that thru R&D, they have developed
the filter to allow for maximum airflow thru the filter. Apparently the
size and shape of the holes in the material have been very carefully
designed to accomplish this. They are also larger the the 'holes' in
the paper element, that's why you need the oil, so that smaller
particles will 'cling' to the oil. I plan to install one, but haven't
yet so I can't tell you if you're going to notice it. I've seen claims
from anywhere from 5-30 hp increases! For $55 bucks even the minimum is
worth the money. That is a comparable rate to what I have seen. Btw,
if I put one on my 3.5 hp lawnmower will it become an 8.5? And if I
then add a Splitfire plug will it add 5 more hp? Just kidding. Just
trying to show that if you put the filter on a 100 hp motor, it is
unlikely you are going to gain 30 hp, that may be why the descrepancies
in hp gain.

It is usually tucked under the air intake on the driver's side, next to the
second battery. It is tie-wrapped and attached to something under there.
I don't remember exactly. It is on the fan side of the battery area, not
the fenderwell side.

Subject: glasspacks, exhaust; attn Lubster
A few weeks ago I made the comment about how glass-pack mufflers can
hinder your new exhausts peak performance. Chris Lublin wanted me to
dig up the article that I read on that and let him know what it said, so
here it is Chris and to all else who may be interested.
It comes from a magazine that HotRod Car Craft produced called 200 power
& performance secrets. I did not get permission to reproduce this, but
as I see it, I'm just piquing others interest to buy the magazine and
I'm not getting any personal gain from it whatsoever, except to know
that I can help someone w/this info. The article is called Exhaust
systems: myth vs. reality.
Myth 1: Straight thru 'glasspack' mufflers outperform high perf 'turbo'
mufflers because a noiser exhaust has less flow restriction:
Adding plenum volume to the intake manifold helps overcome inlet
tract restrictions by 'cushioning the blow'. Properly designed mufflers
perform the same function on the exhaust side, effectively increasing
plenum volume by providing an expansion chamber for the exhaust gases.
Unfortunately, 'glasspacks' --the original high-performance muffler
design--feature a single tube w/louvers and fiberglass packing. While
they look effecient, the glasspack's straight-thru design doesn't allow
for gas expansion. Glasspacks are further handicapped by hight internal
turbulance (caused by the internal louvers) and a short life span (the
fiberglass packing quickly deteriorates). The straight-through design
is subject to reversion, which upsets the travel of the sound waves and
Modern high-performance quiet mufflers use advanced accoustical
technology to both control sound as well as to tune the exhaust pressure
wave for improved performance. The result is a mellow-sounding muffler
that also delivers superior performance.
I don't want to write the entire article here but there is more on dual
pipe crossover tubes and some other stuff. If interested e-mail me
There is also a chart showing which exhaust size is best for a certain
hp range on a given motor:
Power (hp) Single Dual
200-300 3.0 2.25
300-400 3.5 2.5
375-450 4.0 3.0
450-550 4.5 3.5
550-650 5.0 3.5
I figure that covers about all of us.
Hope this is informative enough for you,

In a message dated 1/11/98 7:44:56 AM Eastern Standard Time, jorson sky.net
have a 97 Ranger 4.0L and have a couple of questions.
The advantage of not having to replace paper elements is clear, however,
how about the performance issue? Does the K&N filter improve
performance? Is it noticeable or just theoretical?
Also, how about cost? The truck store wants $45 for the Ranger filter
and another $10 for the cleaning kit and oil. Is that the going rate?

Subject: RA drop brackets......
I have been getting cold responses everywhere I look for 2 inch RA drop
brackets for my 92 Mazda Navajo (explorer). I understand they are not
completely necesary, but I want to eliminate the excessive wear the bushings
are currently experienceing. I am looking for any one who has built this type
of thing regardless of the model to tell me of any pertinent facts to
consider... I figure quarter inch plate and 2 inch square tubbing will be the
stock I will work with putting the correction a bit over 2 inch but close
enough, all grade 8 bolts... Other than that I was just gonna make it a
straight drop, no forward or aft off set, is that OK? Thanks for any

Subject: K&N for a Powerstroke?
I just bought a Powerstroke and was wondering if any one else has put a K&N
filter in their truck. I talked to a PS mechanic at a Ford dealer and he said
he was concerned that the power of the tutbo would pull some of the oil out of
the filter, thu harming the turbo charger.

This fellow is wrong. Lot's of turbo-equipped Diesels use the K&N
setup. Banks, for one. I've a K&N in my truck. Nope - the guy's just
guessin' and guessin' wrong.
