supercharger for rc cars

[lloyd]

I saw a supercharger at the WRAM show. I am getting one for my HPI.
They have a web site at http://www.rbinnovations.com/

Yup, I want it. Hmm... I could fire up the mill and make one, but
there's probably more than $150 worth of aggrivation in the machining
involved ;)

How about a Super Nitro with a .21 and the blower?

Better yet, how about a car built from scratch with a XXXS style
single belt, 2 or 3 speed transmission, and the blown .21?

But I thought that these engines were pass-through exhaust, so the
pressurized air would blow straight through. Is this not true?

shumaker fusion... ofna .25 motor, custom gearing.... supercharged.... easy
100mph +

would be nice for nitro to take the top speed record away from electrics :)

It's technically possible to supercharge/turbocharge a 2 stroke
engine, it just takes a little more work to do it. Dunno if they did
that, but I assume that someone with more time and money than me will
test one before I have the time, money, and car to test it myself ;)

The actual record is still pretty low. Many, many of us have beat it
already (it's around 60 IIRC). Cliff Lett's runs aren't official until
Guiness recognizes them. However, if a group of us were to form our
own group to maintain speed records it would be a different story.
Hmm... maybe we should do that. Anyone up for it?

it says that it compresses air 20 times. at first I thought that was an
excessive amount of boost until this subthread came about, so that makes
sense, it has to be that compressed since it probably wastes half the charge
through the exhaust port before TDC and ignition. I wonder how many piston
rods are going to be bent from preignition....

just let me know when you get iut organized

[sanj.varah]

if someone cooled the air as well, ie pre cooled (intercooler) then
supercharged it, you could get soooo much more power!

being :-)

Actually you want the intercooler after the blower. Air gets hot when
you compress it, so cooling it before the blower would have less
effect.

20 times? That's about 279 pounds of boost. I don't think so, Tim ;)
10 pounds of boost (24.7 PSI total) is about all the engine can handle
IMHO. It's going to have to have a rotary valve on the output side of
the blower so it can be timed, and a non-cogged belt won't be able to
hold that timing. The more I think about it, the less optimistic I am
about the thing working as designed.

For the time being I'll just put a "supercharger" that I know will
work on my XXXS: a 2200 uF capacitor across the battery leads :) I
need to get to that, actually. Need to pick up another pair of Dean's
connectors so I can make it easily removable.

If this is going to happen I'll have to find a few people, 5 total
sounds about right, to form a governing body. I can't make rules
alone. Not fair that way. Any more volunteers?

One could try to increase the carnkcase volume with some extra gaskets
and also extra shims in the head.

I wonder if we run this at night if we will see flames out the exhaust?

[sanj.varah]

i suppose it works both ways because if the air is denser to start off with,
compressing that gives mroe pressure, admittedly the temperature of the air
rises but it may or may not (i'm not familiar with IC engines and
supercharging) give the same power as cooling the air afterwards.

I hope that made sense!?!

well i hope so

So do centrifugal blowers like Vortechs and Paxtons. They're still
blowers.

I have a quick question. Isn't this supercharger just forcing more
air into the engine, therefor leaning it out? If this is the case,
under these circumstances, the engine would blow the piston and
sleeve, maybe even the con. rod every other time you ran it. right?

But thats not what I'm talking about. If you pressurize the air going into
the engine, then it will just expand out the exhaust. So what effect is
this going to have on performnce when all that pressurized air just blows
across the piston? And even if it did work, why would it be any different
from leaning it out? All your doing is cramming more air in there,
assuming it works somehow.

[MikeF]

Im with you. I just dont understand how the 'blow through' configuration
would work. After all, the fuel relies on vacuum to suck it through the
lines...
Having said that, the supercharged OS .91 airplane engine looks pretty cool.
Draw-through design, presumably re-timed crank and ports to eliminate the
exhaust loss.
Costs a pretty penny though!

Look up roots blower and super charger...two different beasts...trust me..A
blower uses two three lobe rotary vane lobes, timed of course, to compress
air, while the super charger uses a turbine, just like a turbo unit to do
its job...the only thing alike about the two are they are belt driven...I
have installed and repaired enough of these to know the difference...on
1:1's

Not true...there is a valve that goes to the tank, where your exhaust tube
used to go, to force extra fuel in with the extra air....

it also "cramms" more fuel in with the air....like a Nitros system.

Perhaps you should know but unfortunately you don't.

A supercharger is ANY air compressor device driven by mechanical means via
the source power plant such as a gear set or more commonly a belt.

There are two primary types of superchargers...

Roots: utilizes 2 lobed rotors. The male and female rotor's rotate
counter to each other. As the lobes of each rotor travel past each inlet
port, air is trapped between consecutive lobes and the cylindrical casing.
The air moves axially (forward) throughout the case towards the discharge
port.

Centrifugal: utilizes a single impeller and centrifugal force to compress
the air. The impeller is the same device used in a turbocharger.

All superchargers are driven by mechanical means. Both Roots and
centrifugal are superchargers.

You are confused with a turbocharger. A turbocharger is also a
centrifugal device but uses a "turbine" power to drive the compressor
impeller. The turbine is usually driven by engine exhaust.

I forgot to add most importantly of all; the terms "supercharger" and
"blower" mean the same thing with regards to combustion engines as opposed
to a "turbocharger".

That's why it would need a valve between the blower and carb, timed
correctly, to make it efficient. Otherwise it'll be doing just what
you said. The engine will catch substantially more air before the
ports close, though. Naturally or supernaturally aspirated, 2 stroke
engines blow a good bit of fuel/air out the exhaust, which is why
tuned pipes exist.

Fuel is drawn into the engine by the air accelerating through the
carb. The more air goes in, the more fuel goes with it. Sure the
needles will have to be opened a bit, but it'll work. How do you think
blowers on full scale cars work?

It's OS, of course it's expensive ;) Their blown 1.20 from a few years

(Bubba looks out the office door into his garage where the ful scale
blower parts are living) Yup, I know what a blower is. I'm putting an
8-71 on a 502 BBC for my Camaro.

A few things:
1. "Blower" is just slang for supercharger. Call BDS, Paxton, Vortech,
B&M, GM, etc. and ask.
2. No mechanically driven superchargers use turbines. Turbines are
devices used to extract mechanical energy from the flow of a fluid. In
this case, it turns an exhaust driven supercharger (turbocharger).
3. There are 3 common types of superchargers: Roots (intermeshed lobed
rotors), screw (same concept, more vanes in a different
configuration), and centrifugal (take the turbine off a turbocharger
and replace it with a pulley and gearbox/belt drive/ball
drive/whatever). Roots blowers are the ones commonly seen sticking 2
feet through the hoods of insanely fast cars that you don't want to
mess with at the stop light ;) Screw blowers are fairly common on
production cars (the T-Bird Super Coupe had a screw type, I believe).
Centrifugal blowers are most common as aftermarket units on fuel
injected cars since they can be remote mounted easily and don't take
up much room (ever try and change the spark plugs on an LT1 powered
Z28? I have and have decided that it's worth the $150 the dealership
charges next time. Good luck getting a roots or screw blower in
there!)

I'm certainly not an expert, but I do know a few things about forced
induction. My project car is getting a Roots, as I said, along with a
bunch of other stuff. The conservative goal is 1000 foot pounds on
pump gas. The front wheels will be off the ground at least 2 feet.

A Blower on a 1:1 DRAWS in air from the carb mounted atop of it, along with
the extra fuel. Of course you have to rejet to get more fuel.
On this rc super charger, there is a pressure port and anti reverse valve
the pressurizes the fuel tank much like a tuned pipe...but pressure is
higher, forcing fuel into the engine.

One small detail i think you over looked. A BLOWER, ie 671-Jimmy, 871, is
mounted to the maniflold. And on top of that there is usually mounted a carb
or two, this system draws in extra air and fuel by vacuum, and compresses
it.
A Super charger on the other hand, has the discharge mounted on TOP of the
carb, forcing air, but not fuel into the engine. The extra fuel is added due
to the fact that venturi velocity is increased by the mass air flow.
There is a difference between a Blower and a Super charger, And I am not
that stupid to confuse a turbo with a super by the way.
I do not know where you guys come from, but around here, if you walked up to
a guy With a 671 on his big block and said nice Super charger, he would
probably smack you in the teeth..:)

Oh maybe I should have said impeller instead of turbine in my first post.

Find a reference you can post here that differentiates a blower from a
supercharger.

If you really want to get picky the term "blower" is a specific reference
to the part of a supercharger assembly that actually compresses the air OR
air/fuel mixture. The terms have nothing to do with the location of the
assembly in the intake system. Since about the early seventies the term
"blower" began to lose it's specific meaning in regards to the actual part
of the whole assembly as those less technically savvy began to interchange
the terms with each other.

Notice the paragraph under the picture of the Roots type blower
(supercharger)...

"The classic SUPERCHARGER is a Roots-type BLOWER which features a two- or
three-lobe rotor design. The Roots-type blower, such as this B&M street
unit, is actually a giant air pump that compresses the air charge in the
intake manifold and cylinders."

last I checked, all the top fuelies had this config:

air scoop
supercharger
intake manifold, with injectors.

carb models are the same, with carbs between the supercharger and the
intake manifold.

Those are a totally different setup.

Not with a Roots type. Carbs are before the blower. Centrifugal
blowers are before the carb/throttle body/whatever.

Nice link...and it only proves my point...In all of your Experienced

No place in that article is there any difference made between a
supercharger and a blower. Your lack of comprehension skills are showing
I'm afraid now making it easy to understand your confusion. Too bad you had
to turn this into a pissing contest only proving your lack of knowledge
rather than taking the opportunity to learn something. I would enjoy the
opportunity to read specific information supporting your claim. Perhaps you
could point out a direct quote and the resource rather than spouting off
your misinformation as fact.
I on the other hand have posted the appropriate information and at least
two sources confirming the facts.

NO! <grin> better yet a supercharger or sometimes referred to as a "blower"
achieves performance increases by increasing the density of air entering the
combustion chamber.

superchargers are connected directly to the crankshaft by a belt unlike a
turbocharger which is driven by exhaust gases. the positive connection yields
instant response, in contrast to turbochargers, which must overcome inertia and
spin up to speed as the flow of exhaust gas increases. a supercharger is a way
to get around "turbo lag". also I might point out that the lubrication system
also differs, in that, a supercharger is self-contained whereas a turbocharger
requires engine oil. end result is a highly reliable system with instantaneous
throttle response!

Increase the density? Oh, you mean like supercooling the air as it enters
the combustion chamber? Didnt think so <grin>.

They both do the same thing. They increase intake pressure by forcing air
into the cylinders via *slightly* different methods. Big deal, its not
rocket science.

ok blowers and superchargers are the same regardless if its positioned before or after throttlebody/carbs to prove my point look at jackson racings superchagre for the civic si...

look at it then replie...

I did not follow your link, but I do know that technically they are the same
thing. It has become common though, to use the terms individually to
describe one or the other

A "supercharger" is simply a device the forces a pre-compressed volume
of air or air/fuel mixture into an engine. A turbocharger is a form of
supercharger, although in the common usage, it is just called a turbo
or a turbocharger. A blower is the name given to a mechanical
compressor used to do the same thing (roots type, screw compressor,
ect), and is another form of supercharger. A belt-driven, centrifugal
superchargers are not commonly called blowers OR turbos, but they ARE
superchrgers because of what they do: compress air or air/fuel before
it enters the cylinder(s) of an engine.

Unfortunately, from what I've seen of RC scale superchargers, all I
have seen ARE belt-driven centrifugal superchargers, but often
incorrectly labled as "blowers". Keep in mind that the term "blower"
is pretty much a slang term, like "huffer" (common gearhead street
lingo for a roots-type supercharger).

Inline position of the supercharger does not change it's name, wether
it is before of after the carb. On the big rides (TF/FC, TF/D, as well
as their TA counterparts), fuel is injected both above AND below the
supercharger (no carb involved, all fuel injection).

Just something I picked up from a bunch of years of putting them on
real cars and bikes.

Superchargers on RC car engines don't work, they look cool, but they do sod
all for the power. I had a guy I know who has installed a few on real cars
in his time explain it to me. Summet to do with valves and ports. Been
there, done that, got the t-shirt.

They must work to at least some degree, a friend of mine helped a
friend of his radar his car doing before and after he put on a
supercharger, , it DID make it faster, something like 66mph without,
and like 81 with. it was quite the jump, but they estimated that twice
as much fuel was being used.

There is no reason a supercharger wouldn't work on a nitro enine, but
much of it's advantage will be lost outside the RPM range at which the
pipe works best because alot of the compressed charge would simply go
through thecylinder and out the exhaust, , ,but when the rpms are
where the pipe works best, that would be stopped. I see why one, if
they only looked at a blueprint and didn't know how the engine and
pipe work togethe, would think it would not work at all, since the
exhaust port is higher than the intake, thus is closed sooner. Also,
and crankcase leaks would severely cut the effectiveness of the
supercharger drastically.

People have sucessfully used superchargers on full-size 2-stroke
engines, I personally saw one at Bonneville in the 80s on a dirt bike,
I seriously doubt they went all the way to the salt flats without
knowing what they were doing.

I have to say though, espically on a nitro engine, unless you did alot
of engine mods, you would be spending quite a bit of money, and
wasting butloads of fuel, and risking ireperable engine damage for
very little power gains.

I saw a supercharger at the WRAM show. I am getting one for my HPI.
They have a web site at http://www.rbinnovations.com/

My self and three other friends bought the Losi Aftershock. We all worked together tuning each truck. I myself decided to purchase the RB Supercharger. To my disappointment I did not notice any gain at least nothing to mention. The super charger installation was simple and could see no error on my part. To further my disappointment I purchased a NOS kit from RB that I also notice no improvement.

I have attempted to contact tec support several times with no reply. I am left with no options other than to return the product to Tower Hobbies. Products are only as good as customer service. I strongly suggest they re-evaluate thair marketing strategy.

As you can see I took great pride installing the system. http://www.masonic175.org/images/Potluck/losi/losi.htm

I went through a lot of work and money in hope of some performance gain. You would be better off to buy a larger engine.

Thanks for the website, anyway, how much will it cost for the affordable but quality superchargers?
