Has anybody fitted their CR-V with a supercharger? I've seen one on
the web. Unfortunately, no specific details were given such has
amount of performance increase. I'm just curious as to how much more
KW can be eeked out by installing a supercharger.

Thanks for that reference. I actually saw the supercharger at another
website and so I'm not sure if it's of the same make. Anyway, I've
checked out the website but... still not enough information.

By the way, what's the conversion factor from BHP to KW?

I don't have the conversion. My jackson racing catalog is listed in sae specs. The details I have is a 30 ft. lb. increase in torque (across the band) and 50 HP at redline



thanks for responding



Jesse

will the supercharger work for 99 and up CRVs or is it meant for 97-98 only?

there are two different kits, one for 97 and 98, part number 989-700, the other
for 99-01, part number 989-705
both cast the same, $2949.00
Jesse

are there things i can do to help with high-end and
low-end power without buying a supercharger, cause its
kinda expensive

Yes, there is something that will help your low & high end power it's called
DODGE VIPER!!!

Yes- you can add an air intake and exhaust upgrade to the CR-V. There are a
dozen other mods available (bolt-ons) but these are a good place to start, I can
email you more later if interested.

Air intake- a couple of options
You can either use a drop-in K&N air filter, which will fit in the existing air
filter box, or get a full-blown replacement air intake system, which goes in
place of the entire air filter system.
The drop-in is an easy option, costs about $45.00 from pep-boys or through the
web (if it isn't listed for the CR-V, I hear its the same as the civics of the
same year, but double check by cross-referencing part numbers). It will probably
increase engine output by 2-5 real horsepower. It might increase engine noise
slightly.
The replacement air intake system replaces the restrictive plastic/rubber elbow
between the air filter and intake manifold with a freer-flowing aluminum or
high-temp plastic elbow. The air filter is a larger cone-style unit which allows
much more air to enter the engine than the original or drop-in filter. You might
experience an increase of real horsepower of 5 to 10 HP with no other engine
mods. You will however experience a lot more noise when you press the gas
pedal--on my 89 civic Si the engine sounds like Chewbacca growling when the
throttle is opened, a noise some people like, others hate. They run between $100
and $200 or so and may require some minor modifications to the system. Both
K&N-style are oil-impregnated cotton filters which filter out a lot more
contaminants than the paper filter currently on the car. The systems offer a
lifetime warranty on the filters, with filter cleaning and re-oiling needed
about every 50,000 miles.

Exhaust- there are a few systems on the market available in 2 sections, the
header and the rest of the system. The header comes in different configurations,
made of different materials, and may be 1 piece or 2 piece designs. I can give
you more details on this in another email if you are interested. The header
replaces the existing, restrictive cast-iron 4 into 1 header with a freer
flowing system. It will also increase engine noise. a header alone will give you
8-15 real horsepower. They can run $200-500, depending on a lot of features.
The exhaust system usually has larger, freer flowing pipes leading to a less
restrictive muffler. depending on the design of the system, the pipes and
muffler may be made out of stainless steel or painted mild steel, amd may have
more than one tailpipe. an exhaust system will definitely increase engine noise
and can run from $300-600. There is such a broad difference in systems that,
together with an intake system and header, one might be able to create 15-40
extra horses.

After these mods, you might try a larger throttle body, a fuel-pressure riser,
adjustable cam sprockets, different cams, porting and polishing, lower engine
mods, dry-sump oil systems, racing pulleys........

Jesse

yes, but does a Viper come with a picnic table? room for 5? and how is it on
those icy mountain roads? gas mileage?, insurance? Cost of ownership?
reliablilty?

You know, I work as an engineer for BMW, I drive M3's & M5's every day- and I
still happily drive home in my wonderful CR-V SE every night. call me crazy.

Jesse

I call you a smart engineer, a friend that is a BMW mechanic locally, drives
an Accord V6 home very night.

You make it sound so nice you almost had willing to spring some more cash
trying to find more ooomph for my V. Question though, are you speaking of
what these type of mods would do in general or what these specific mods
would do on a CRV with a B20 engine. From what I've read elsewhere, there's
little power to be gained from intake, filter, or exhaust mods, and some
have actually lost power with them. I think I read somewhere that some major
intake manufacturers don't even make intakes for CRV because of this (AEM?).
If it takes a supercharger kit at $5,000 to get 50 horsepower I don't think
its realistic to expect anywhere near 40 hp with intake/header/filter and
exhaust. I think everywhere that you've listed a range for hp gains you
should dump the high end # and stick with the bottom (15-40 horse?). Also,
one should consider that often with exhaust mods you gain a tiny but in very
high rpm peak horsepower but you lose usable torque, which is what you want
90% of the time. My $.02

Thanks Michael. I am talking general numbers- these numbers aren't CR-V-specific
and reflect general claims by aftermarket performance manufacturers across their
product line (for Hondas). Keep in mind that considering the displacement
(2liters) and design of the engine (a very efficiently designed aluminum
twin-cam engine) there is a lot of power potential in this engine that is not
being utilized by the mass-produced and mass-marketed stock engine. The stock
airbox is (relatively) restrictive as is the cast-iron intake manifold, which
does not utilize power-increasing technologies such as coatings or cylinder
scavenging (a 4-2-1 header will increase low-end torque, a 4-1 header is for
high-end torque).
On top of this, one main reason performance decreases with some of these
bolt-ons is the resulting lean-running condition (due to "too much" efficiency
of the performance upgrades). There is so much more air entering the intake
manifold with an air intake system that the fuel has a hard time keeping up with
the boost in air supply. That is why it is almost imperative to add one or more
of these components: A fuel-pressure riser(B&M makes one for Hondas, don't know
if its compatible), Higher pressure fuel pump (Holley (& others) makes a few for
Hondas, again don't know if its compatible), larger fuel injectors, a
reprogrammed ECU (bullfrog & others), or some type of electronic "cheater
module" (there are a few on the market) to deliver more fuel for the given
volume of air.
I don't recommend "throwing" these components in indiscriminately as soon as you
can afford them. The best thing to do is properly "blueprint" the engine, add
the components a few at a time, test the results on a Dyno (or by the seat of
your pants). Then share your results with others.
Not to get into semantics, but the Jackson supercharger runs $3000, comes
complete (less replacement manifold gasket), is super-reliable and maintanence
free, and can be installed in a few hours by any weekend mechanic worth his
salt. If I had 3 grand to spend and was really disappointed with the output of
the CR-V engine I would go for it (I should mention I am not disappointed with
it, and don't plan on any performance upgrades in the near future. I spent my
lust for speed on my heavily modified 89 Civic si)

Thanks for the $.02

Jesse

These type of mods (intake, exhaust etc...) would really benefit from
changes to the Factory Engine Managment system.

Powerchip (http://www.powerchip.com.au) have a chip for the CR-V starting
from AUD$715. They have several different chips tuned to suit different fuel
octane ratings.

The 98 Octane chip is claimed to give an extra 13kw (or 17Hp - from memory I
think 1HP = 1.34kw).

I don't have one of these yet, but would be interested to hear if anyone out
there gets one!

Hey, I'm with you. I think by the time you add up the time and money trying
to get significant gains out of bolt-ons you will have bought a
supercharger. I used $5,000 because I figured by the time you paid for
shipping and installation you'd be around that figure (I wouldn't trust any
weekend mechanic installing major internal engine parts on my beloved
V...that includes myself). But I also agree that it's not really worth the
money trying to make the V go really fast. If I want to go fast I'll go hop
on my hayabusa which can run zero to 60 in under 3 seconds and will eat most
any viper for lunch.

CR-Vtec. nuff said? no, add a turbo. make the jackson look like silly.

lates

it will look even sillier to see your turbo blow up



Jesse

Jesse, where did you find headers for a crv? The intake is the way to go. I
have noticed a big difference. I also have magnour wires[8.5]. MSD offers
help for the eletoric part, [They do away with the present coil and you can
use an extermal one.] thanks Marc

I saw a set for sale on ebay. Check out Item # 597635341 .



you know, I debated an external coil on my SI, its only worth it if you use an MSD module or something similar. I upgraded to the thick MSD wires on my SI, but just for looks. The honda ignition is excellent,and well up to the task of igniting the mixture. I just wish they did away with the distributor on the CR-V. NOONE uses a distributor any more.
