Richer doesn't make more power. Less fuel to air does though, to a point.

Unless the model aeroplane is 4 stroke it won't work on that either. I do find it funny when people with R/C engines which are 2 stroke put super chargers on them, I mean its completely stupid...when you have your intake stroke your exhaust ports are open for scavenging, any excess air is going to be used to scavenge the cylinder!
They do absolutely bugger all!
I do love my R/C cars though, tiny little .21cc nitro engine, 2 stroke, but the car will do 0-40mph in 1.5 secs and then onto 70+mph with its 3 speed auto gearbox and 4WD. Great fun! Bloody expensive when they break though, which is inevitable!
Oh and yeh, electric superchargers from ebay, waste of time!

I think it was disrupting the airflow, TBH not sure if it was MAP or MAF.
Gbduo, I'd love an RC nitro car, but I'd only play with it for 30mins and it would never get used again, thus wasting £200.

FACT*: If you wire two up, one behind the other in the intake tract, and make the first one spin faster, then you'll create a lovely area of compression, and you've actually then converted the engine to a turbine!

The Roots TS was similar, but one of the opposed pistons did the exhaust ports & the other the inlet. But those SCs are to replace the inlet stroke, rather than to increase power as such.
IIRC, DD made a 6V-92T with a turbocharger on top on the supercharger!

.Then it is just the cost of running them! they are good fun! Better if you have a local racing track though which uses R/C cars but most of them are now using electric cars because of noise regs.

People are confused that many superchargers are borrowed from the old Detroit Diesel two-stroke (as in a Jimmy haulin' hogs); they had a conventional wet sump & an exhaust valve.

But yeh, normal strimmer 2 strokes and simple 2 strokes ain't gonna work with 'charging!

Go on ebay, you can pick up the Schumacher Menace or XTr (the two I have with good speed) for less than £100 now...

, I'll want one now . Is that a full kit, nitro car, remote control etc for £100?
