Default RE: TURBOCHARGER on my nitro car, and it works

The RBInnovations supercharger does not in fact "supercharge" RC engines. The extra air that is forced in through the carb merely blows out through the exhuast port as killer89 mentioned before. Therefore when the air and fuel is forced out of the exhaust, you are merely leaning the engine by taking away the fuel and replacing it with air. Therefore, instead of paying $180 for a heap of metal, you can just lean out your engine. Also you have to realize the supercharger is draining HP and torque from the engine by giving extra load to the engine to spin the vanes.

BTW, shvdcat if you want to race supercharged, watercooled engines, why don't you come on down and race my Charger. Then afterwords I'll smoke you with my Rustler.

P.S. I believe he is running a traxxas engine, not a marine engine. So he did have to modify it.

lol, the little chart on the RB site is just a basic "how 2 strokes work" with the word "supercharged air" added to the chart.

You also used rbinnovations as an argument... I could make a site selling powerade for RC cars saying that boosts horsepower as a fuel additive.

I dont understand how people can backup these superchargers or turbochargers. The science is just not there to make them work.

YOU CANNOT COMPRESS AIR IN A OPEN CHAMBER.

I dont know how much more clear one person can get. The best upgrade for your engine is to just get a tuned pipe. Do some research and find out which tuned pipe is best for your engine. I gurantee that you'll get more power out of a $50 Tuned pipe than a $180 supercharger or this guys turbocharger. They're purely cosmetic and if anything, hurt performance.

Alright - I have had enough!

This is rediculous! This member comes on to share an idea, and gets nothing but grief. Everyone bashing in this thread should be ashamed of themselves.

If you feel that this member is being untruthful, explain so in a proper and polite manner. There is no need for the kind of comments made here.

This thread is now locked.

The very same concept of making a radiator. Head onto youtube and search for how to make an intercooler. In all honesty, this is a huge waste of time.

Posting the same thing in at least 3 different threads is not a good idea; some folks get a bit annoyed by it FYI.

Also It doesn't appear that your setup is any different than the last photo you posted. Have you tested the various exhaust systems on the engine yet on a test stand?

Sadly no, I ruined the fuel cooler by working on it with hands free tools so ill have to buy another one once I get a drill press, the holes I drilled were pretty horrid, but I did change the stainless exhaust tube for a clear hose with a short stainless endcap tube, and waiting one the Co I'm working with to send a new turbo

Snake those turbos are just gimmicks...

I bought a few and they are just mass produced Chinese castings. They are meant to be with your keys, not on an engine.

I'd like to see what kind of tolerances they're made to, and if spun fast enough, will they actually produce air pressure above atmospheric. At some point, I'm going to take a RB Supercharger and modify it to actually produce some air pressure and test it out on a small aircraft 4-stroke. I have a .46ci that would be a good test subject. A turbo would be even better on a 4-stroke, but making a working turbo that small requires some very tight tolerances and very intricate machining processes.

Not much. The housing are cast, and so are the impellers. I have a few I'll take pics of.

I was planning on getting a air matress pump on a spare magnum I have laying around just to experiment. I think I made a post last year saying the same But it's a pain to tune and I'm a lazy bum.

I'll get to it this weekend since I'll have the car up on jacks and I have no tv.

Here are some pics of the second gen turbo i believe. They have an updated impellers according to their website.

One of the major issues is the shaft and bearings. The stock shaft is some type of jewelers/watch bolt, way to small and easily bent. I guess you can use an rc tie rod if the center is an adeqaute diameter for the bearings and if the threaded shaft end are small in diameter.

Maybe searching a watch hardware supplier website or going to a local hobby store and check their screws/tierods/pushrods

I will say that the CNC is interesting to see, the small box and the idea of the airplane pumps. It seems like a ton of work for a minor amount of gain. Even if you seal the engine up and down I cant imagine that the amount of compression you will add will be that much. You can only fit so much atomized nitro and air mixture into there at once. I know that RB has marked this for years under a huge cloud of controversy. They know that it does increase the temp of your vehicle and they compensated for that with an increase in pressure from the exhaust to push more fuel. If it works in providing you with a minimal additional amount of thrust and you enjoyed building it then more power to you. For those who don't see the value in it, or don't see the pros overriding the cons... I'm right there with you.

Hey I know this was years ago, but do you know how you made it and if so, do you have plans for it?
