Has someone tried these before ?
I wanted to add one to my 1.9td aaz (it has a K24 turbo), just to get some more boost at low rpm,
can it hurt my engine ?
There are kits on ebay in the USA for about 25 dollars and here in Europe they cost around 150 dollars , what the difference or is it just the price ?
-
Those electric super chargers always seem too good to be true.
Can they really make good CFM at decent pressure?
-
Most of the cheapo "electric superchargers" are scams. It takes a strong motor to produce decent boost pressure at the flow rates engines need, and strong motors draw a lot of electrical power.
-
These actually rob you of power most of the time.. They act as a restriction and can cause some odd turbulance (the turbulance doesn;t really affect a diesel too much though)... Like Turbine said takes a strong high RPM motor and a pretty big fan to move enough air to even equal what your engine would require without the turbo...
Just about all of these are the equivelent to the fan on your heater, some might rate up there with a leaf blower....
-
I'll bet if you bought one and put a balloon over the outlet it would have a hard time popping the balloon. Something cheaper than your heater blower motor is supposed to pressurize your intake?
-
I doubt they could inflate a balloon since the elasticity of the rubber could pressurize the air more than the fan... These things actually originated as an auxilary blower for automotive HVAC use..

may work on a lawnmower.

or one of these?
i would need a battery and bracket to hold the battery
it just seems like it would be more hassle then gain?

Get one and do it Duane.

i'd rather stick a K03 on it! then mess with all that electrical stuff!
you know me i hate electrical stuff!

Its not really hard to slap a turbo on a a N/A diesel. And you will get an actual increase in power.
-
Yeah, these are a real scam... Some guys have made real electric superchargers, but they use a remendous amoount of electic power and it has to come from some place.... Here's on that suceeded. Notice it has 3 LARGE custom built motors to power it.

:shock: wow all I can sow is wow. I have always thought the science of it was sound but never expected that.

sweet jesus.
The ebay seller's store page looks like a joke after seeing that.
-
Yeah, notice the small gauge wire on that cheep "blower" - what ? 12g ? So you're looking at maybe 30 amps ( 420w @ 14v). Your 1.9L engine needs just over 100 CFM at 3000 rpm. Look at the HP requirement for a 100 CFM compressor even at only 15 psi. Quite a bit more than a 420 watt motor can do for you.

They are a total joke.
They dont have the power to create any meangingful increase so you might as well flush your money down the toilet as opposed to buying one!

Use an air compressor to charge a fairly large air tank under normal driving, then a dump mode into the intake manifold, for acceleration. This would probably get you results as good, or better than the standard electric supercharger kit found on ebay, and the like.
this is not to say an Ebay SC kit is worth more than a pile of human excrement, only that an air compressor would be as useful as something useless, if not more useful.

laughing my ass off at last post :P
-
Those ebay superchargers are cheap overseas bilge blowers we use in marine to remove vapors from the bottom of boats (actually don't even use the cheap ones). Probably go to your local West Marine and get one cheaper.(or without the shipping cost$)
In front of your turbo - it would act as an obstruction.
That post with the Nissan is really funny, I wonder if any documented HP gains could offset the extra wieght of that stuff and all the batteries, etc.

What's anyone's opinion on 2 cycle superchargers????

It's going to be a bugger to reach under the hood and pull the starter cord when you're sitting at the light and decide to race the guy next to you. (Not that anyone in Ontario would even consider this - we know it's illegal).

LOL !!!! Yeah, if you can run the pull cord through the FW to start it when you want boost !! :-) I actually sat in a WWII aircraft that was similar to the Piper Cub. It had a pull cord through the FW to start the thing !!!
OK, you reminded me of a small accessory I want to add to my IDI Caravan. I have loads of room under the hood. I have a spare 65a alternator and a spare 2 stroke large leaf blower motor, and a fresh rebuilt 3.5 hp Tecumseh motor. I have been caught in the cold with a low battery on my diesel rabbit before with no one to jump me. So, what If I married one of these engines to the spare alternator for an under hood APU ? I would not mind popping the hood to start it if needed. Over kill ?
