If you would, please explain why it wouldn't work.

There are MANY GMC 53 and 74 series diesels on the road. Sesign is somewhat
different but still a 2 cycle.

No, a diesel uses valves, just like a 4 stroke, hence the reason you can use
a turbo...they are not 2 stroke...look it up...

Because, in a simple 2 stroke engine, the intake and exhaust are open at the
same time for most of the stroke..so you would just blow the extra charge
out the exhaust pipe...

Ok, well technically you can, but for the reasons Jon mentioned, you
wouldn't want to. Basically you would have to seriously richen the fuel
mixture to achieve the same level of performance since the motor isn't
getting pressurized by the turbocharger (or supercharger).

Snowmobiles built for drag racing have turbocharged 2-strokes. They are
extremely fast too. So I guess it can be done. Perhaps the ports are
designed specially for the purpose, with less overlap?

Just use Nitrous....or as Vin Diesel would say "Naaaaws"

Sorry Jon but 71 & 53 series are, in fact 2 strokes. The blanket statement
that diesels uses valves is absolutely incorrect. Look it up indeed.

Not starting a war- posted info should be accurate.

Yeah, and re-timing an RC engine would take some serious work.
Anyone try a Novarossi? Costs less than a turbo!
True, it doesnt have the same cool-factor, but PLEASE, even a bone stock ST
is a pain in the ass to maintain....you wanna add a turbo?

Haven't found the diagram for this engine (53/71 GMC series). It is not a
reed valve engine. There are a huge variety of diesel engines. Will see
whait i can dig up.

Jon, Diesels are not limited to 4 stroke, but the two stroke Diesel is quite
different then the 2 stroke RC engine. It would be too difficult to Turbo
Charge a 2 cycle RC engine, but not impossible......just not cost efficient.
Here is a link that explains 2 stroke diesels.

Which post was that, the one in which you said "Hmmm...well maybe I am

talking about, seems to prove the opposite to me.

If you really want to know, my opinion is that you cant turbocharge a small
RC engine because a turbo that small is too thermodynamically inefficient.
you cannot turbocharge small RC 4 strokes for the same reason. (cannot in
this case meaning you cannot get any reasonable gain). You can turbocharge
two strokes, if fact some types of two strokes simply will not run without
being supercharged, as it is the only way of getting the air/fuel into the
cylinder with a conventional crank arrangement.

Thanks for the link Pat...and as I suspected, it uses valves (exhaust in
this case) and fuel is INJECTED..perfect for a turbo, but like I said a
typical 2 stroke would not work with a turbo, blower, or No2. Like Kerry
said, if it did you would see it on a ton of 2 stroke machines...

As I said..a typical 2 stroke cannot be turbo charged, as Pat points out,
yes there are designs that can and need to be charged, but thermal dynamics
aside, you just can not use a turbo, blower or No2 on a TYPICAL 2 stroke.

Greeting Everyone,
Just a quick note here.
My son and I have created a N2O system for typical 2 stroke RC nitro methane
engines. It would probably work on 4 strokes too, but we haven't done any
testing yet.
We have been running it on a T-maxx. It's very cool. We're in the process
of trying to get everything developed into a product. We've just about got
our patent issues finished.
I can tell you from experience that a 2 stroke can work very well on N2O

I'll be posting more info soon.

To answer the question, there is an increase in torque, hence hp. There
is not necessarily in increase in rpm.

There are lots of posts saying that it cannot be done. That is not
true. Two cycles can be turboed but it is not the most efficient thing
to do.

There was a post or two that said that the extra mixture would blow out
the exhaust. Well that does happen right now without turbos but we all
use a pipes to work with that. The correct pipe design will reduce the
losses, enough to show an improvement in power. Rather, the harder part
is where to find a turbo small enough for our engines? Any ideas?

Design considerations to maximise the use of a turbo: The advantage of
the turbo is that the intake duration can significantly increase. You
will have to increase the crankcase volume to hold the mixture and to
have a reasonable back pressure on the piston. The port time area of
the transfer and exhaust will have to inccrease to handle the extra
mixture. Scavenging become far more important to he head design that
compression efficency. Get a book on two cycle design to help you work
out some starting numbers.

i came by this thread on a google search and found it interesting so i decided to bring it back to life. You can in fact turbo or supercharge an RC engine but first off it would have to be mounted at the end of the pipe so it doesnt interfere with the exhaust waves. Secondly, the intake ports would have to be made larger to compensate. The crankshaft would have to be modified so that the blower could create pressure in the crankcase instead of vacuum which is how the rc engine normaly works. It would have to have a slot or something cut into the side that is closed to the carb after TDC for a slight duration. I dont see why one wouldnt work if the proper modifications were made to the fuel intake system.

WOW!!! That thread is 5 years old.

Starting at around $159 RB Innovations has been producing a supercharger for
nitro engine for around 4 or 5 years now.

I have a friend that has one on an OS engine in a serpent. It DOES add
power if it is tuned right. It is super sensitive to tune, and it seems
like it's only in tune when running wide open, and the bottom and mid
sucks. It's purely for top-end power. No matter what we did, we couldn't
make the same engine without 'charger push the car nearly as fast as
with, with the exact same gearing. I thought the same thing, that a
non-supercharged motor would have same or more power if tuned correctly,
but it didn't happen. It did take quite a while to find the sweet spot
with the supercharger, but once it was found, it really ran.

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
