Escksu Clutched December 31, 2011 Share December 31, 2011 OK, I know there has been countless threads on the net about it already. Decide to do my own review of it to answer the question. Bought a kit from ebay. http://www.ebay.com/itm/290635061663?ssPag...984.m1497.l2649 Thats the exact kit I bought. Bought 2 pieces 4" to 3" reducers from Man Exhaust today and install it. Wiring is quite simple. I wired it to the fog lamp relay thus I could turn it on or off thru the fog lamp switch. Thus the big question is does it work? Is it snake oil? Will it do wonders? Drove it around for ~100KM today as I was running some errands. In short, it does work to a certain degree. I ensure there is minimal placebo effect by turning with the switch on and off numerous times. Run at different RPMs, level of throttle etc. The amount of power boost is very slight. Its very similar to turning off the AC on a small CC car to gain more power. It does what it is advertise to do. Gains of around 5-7HP. Thats all. So, why aren't manufacturers using this device when its so cool?? Reliaibility and durability. These devices are not made to last at all. Housing is just fiber reinforced plastic and motor is a simple brush motor (though its using ball bearings). At best, it will last you around 600-800Hrs of use. After that you have to replace the carbon brushes or the housing. Fan blade is metal so it should last a while. So, can it be made to work? Yes, it can. Provided there is proper R&D. Eg. cast aluminum housing. brushless motor (there are water cooled motors as well). Fan blades that are designed to deliver high air pressure etc.... Electric superchargers and hybrids are already under research right now Btw..... I am not sure if this device can be used on vehicles running MAF. Mine is MAP so its not a problem. ↡ Advertisement 1 Link to post Share on other sites More sharing options...
Escksu Clutched December 31, 2011 Author Share December 31, 2011 Btw, if you want to see an electric supercharger that is definitely working and not snake oil stuff. Google Thomas Knight electric superchargers. It does work but its power consumption is really insane. You need a separate battery for it. Also, it can only run for very short periods of time (~20s). Only good for drag racing. Not for daily use. Link to post Share on other sites More sharing options...
Vega Turbocharged December 31, 2011 Share December 31, 2011 What car you install on? Do a dyno with and without the charger on. Like that you don't have to second guess. Link to post Share on other sites More sharing options...

Parallel air filters improved FC about 10%, besides better acceleration. But engine sounds like tuned for racing. I believe a 100HP engine = 110HP engine? 1 Link to post Share on other sites More sharing options...

I ever consider that electric supercharger (it can work) before I decided to install parallel filters. Link to post Share on other sites More sharing options...

Escksu Clutched December 31, 2011 Author Share December 31, 2011 (edited) Supercharger drains 900W from you're battery but your alternator only produces 400W? WTF My alternator is 85A one which is over 1000W. Btw, 900W is just the peak power consumption. When RPM increases, power consumption goes down. Unless you purposely jammed up the motor, it will not consume anywhere near 900W. Edited December 31, 2011 by Escksu Link to post Share on other sites More sharing options...
5936 1st Gear December 31, 2011 Share December 31, 2011 Yes it worked. Is your fan installed before or after air filter? I always have the phobia that blades spinning at high RPM may disintegrate and enter engine through.... I placed fan before air filter, as a security measure. Though I lost precious air pressure generated by the fan. 1 Link to post Share on other sites More sharing options...

5936 1st Gear December 31, 2011 Share December 31, 2011 good Has your FC been affected with this upgrade? My FC gone south slightly. but it's worth the experience. Especially during the first few weeks of "discovery". Link to post Share on other sites More sharing options...
Escksu Clutched December 31, 2011 Author Share December 31, 2011 good Has your FC been affected with this upgrade? My FC gone south slightly. but it's worth the experience. Especially during the first few weeks of "discovery". Not at the moment for me. Its still about the same. Maybe around 0.2-0.3KM/L lower. But can't tell cause I am trying out various driving patterns to see the effects. So, its not my usual driving style. What I like most is the low end torque. Cause it did improved for me (for myself, others I don't know). I can be more relax on the clutch. Previously need to control more to prevent engine vibration.

Good-Carbuyer 1st Gear December 31, 2011 Share December 31, 2011 Why not sequential filters? I have no idea how this can work. Can share the logic/theory for this method? Link to post Share on other sites More sharing options...

Especially during the first few weeks of "discovery". I am also experimenting on some RC brushless motors. They are better quality and spins faster than the supplied motor. Btw, I am still trying to find some high pressure blades which could improve the efficiency a little. Just treat it as my past time hobby...... ↡ Advertisement Link to post Share on other sites More sharing options...
