Default Whats the deal with SuperCharging? Anyone doing this? Looking for opinions on this

hello fellow nitro heads

Seen some info on the supercharger kits available by
"www.rbinnovations.com" and "www.mppa.biz"

the RB kit s pulley driven and the mppa is electric powered and is said to be better.

Is anyone actually using these kits and how do these things perform?
Are they worth the $160 to $200 investment and is there a big notice in power delivery?
Also are there any reliablty issue's?

Any input would be great.
thanx

btw.....i have a Mugen MT.12 motor

it doesnt work since these engines have no valves. also the exhaust port and transfer ports are open at the same time so any extra air you are putting in is just going right out the exhaust. it is a gimmick to take your money.

150 bucks to "look cool". i would buy some titanium or carbon fiber something to look cool and actually get a benefit. bseides the mt 12 is a good motor to begin with. if you really want to blow 150 bucks just save another 100 and get an ns3

Checkout mxwrench's 4-stroke thread.
it looks promising. cause we can use supercharger or even turbo charger on 4 stroke engine.
it'll be sooooo cool..

that would probably work, the only thing is the ducting would be kinda hard since the carb is usually at the rear of the block

Ya it would be money better spent if you used a couple hundred-dollar bills to prop up an uneven table. Supercharging a 2 stroke is difficult even on full scale engines, nevermind little nitro motors. It takes a lot of precise tuning to get boost to work on a full scale 2 stroke. Save your money when it comes to these things.

you can supercharge a 2 stroke. You are pressurizing the crankcase.. remember the fuel/air goes into the crankcase and is then forced into the chamber, the more you fill the crankcase the more that is available to put into the cyl. I have seen turbocharged snowmobile engines and with the right tuning they run very fast. However I have my doubts about getting a blower to work right on one of our motors... but... maybe the xtreem mag boys will dyno test one to see

You would be better off trying a cheap way to make HP by cold air induction- make a scoop that sits atop the roof and forces clean cool air into the carb- the roofline is the cleanest air coming across a race body. If you have a strong motor any extra power down low (low speeds) would be wasted anyway. Just be sure to keep an eye on your high speed tune since it will lean out with the cool forced air. The other posts are correct that mechanical forced induction is a waste on 2-stroke nitro motors since they are so finicky. The small amount of pressure you will get from cold air induction is about all you can use anyway.

If you want more power and plan to get that supercharger to get the power, just send the money to me. That'll get you the same hp increase and I'll buy me a new engine. Seriously, you'de be a lot better off to spend the money having your engine modded by someone that knows what they're doing or just buying a new engine that has more power to start with.
