here is the website where you can see more pictures of the supercharger & read about how it functions. www.mppa.biz
I am familiar with the RB innovations Supercharger. I did alot of research on both of them before I made a purchase. The only thing I didn't like about the RB kit is the fact that it is belt driven. This means that it takes power to make power. And not to mention the RB kit cost alot more when you start adding the upgraded features (intake manifold, under drive pulley's, belts, air filter kit, etc). Once you have bought all of the components your looking closer to $250 - $300 dollars. I got my MPPA SC for $159 including shipping. It came with all the wiring, speed control, Y-harness, intake coupler etc. The only thing I had to supply was a battery & as mentioned before it's not even required to use a seperate battery for the SC, just my preference. You can use the standard (4) AA receiver pack if you want to. Also from my research I found out that the volume of air that the MPPA electric SC produces is a whole lot more then the RB innovations product can produce. And thats if you run the MPPA SC at only 6v and the SC can produce even more airflow when you supply the supercharger motor with a 8v power supply.
It kinda sounds like a hair blow dryer & has a nice tone when you pull the throttle kinda like a wooooosssshhhhhhh sound.
I know all about the so called (myths) of supercharging a 2 stroke engine. I have been into dirt bikes for a long, long time. So I am very familiar with the 2 stroke process. I can honestly that even though there are no intake valves like in a 4 stroke engine the supercharger does work on a 2 stroke. It mainly helps with the scavenging process which allows the cylinder to clean out the old fuel & help draw in a fresh supply of new fuel. Another thing I have noticed with the MPPA supercharger is it seems to cool the incoming air charge. If you touch the supercharger after it has been running for a while it is very cool. So as anyone with some kind of automotive knowledge knows, cool air is denser >>> (molecules are closer together) which means you can pack more air into the same amount of space. This allows you to burn more fuel during each combustion cycle which inturn produces more power. It really is an amazing process. If any of you want to learn more about this I suggest you read this http://www.idavette.net/hib/nitrous.htm
It's an aticle about nitrous oxide & how it works. Nitrous is basically a "chemical supercharger". There is alot of info in this article that will help the unknowing understand how turbo's, superchargers & nitrous effect the combustion process.
As for my stock (polished, bored & port matched) AE exhaust system it seems to work ok. I been thinking of replacing the pipe to something with more volume, but the distance between the front tire & the intake manifold is limited. If anyone has suggestions for a good pipe, my ears are open. I seen there is a company that makes CF exhaust pipes but I think they are alittle too long my application. I can't remember the name of the company but I think it starts with the letter (V). I noticed the pipe in last month's issue of RC car action. It was a very nice looking piece, but I'm sure it will be pricey. I kinda like this pipe http://tsais.com/products/exhaust/cu...e/TS13C640.jpg
but I'm sure it's more eye candy orientated then performance wise. Sorry they didn't have a enlarged picture of the left hand side pipe. I figured this pic would do.
