Air Intake question

Hi all, before I get shot down I am seriously asking this question. the link I have posted ( http://www.ebay.com/itm/BMW-Electri...Parts_Accessories&vxp=mtr&hash=item3a6d7a1f29 ), does anyone know about it or have any recommendations for or against it/
I am just asking and really dont know about it. Reading about it seems interesting or is it another one of those wank things that wastes your money/ Honest opinions please but dont shoot me down.
Thanks in advance

 

I call bull shit on those. Save your money and buy some fairy dust. More chance of getting extra killer wasps out of that stuff than one of those.
Cheers Dave

 

if your going to get one get a half decent one. brushless is the only way to go

Spend your money on a list of stickers for the mudguards. Any of these type of things are complete bull shit. For a supercharger to make enough pressure to increase performance , they generally consume over 30% of the engine horse power just to turn them. For a little electric motor that size to make in excess of 100 hp is crazy talk.

 

Closest you'd get.

I did the numbers a few years back with multiple heavy duty brushless motors.

Say at 6000rpm your 3l motor your motor draws 18,000l of air a minute, or 636cfm.

Your best force flow at max 60amps is 800cfm, which is like 25% more and enough make some positive pressure.

Problem is 60amp draw is a large massive amount and your really not getting anything for your trouble. Its really not that much more than a bottleneck and its costing you quite a large draw. If the device were to be set to open at lower RPMs then it may beef up the curve a bit, but still costing you a huge amp draw more of the time.

If I was to do it seriously, I would get 2x60amp electric chargers, capacitors to suit and use one for each side of the motor. But the cost is getting quite large at $1500+. And then the results may or may not suit?

Both the battery and alternator would need beefing up and some heavy power cables also. This makes the cost even higher at 2k+

My conclusion was it was possible but not reasonable or economical.

 

I have seen one of these (the OP's link) in our workshop. It provides no more airflow than a good computer fan. I would say forget it. total waste of time in my opinion. There is an electric turbo that was mentioned on the forums a while ago and >>>>> http://www.aus300zx.com/forum/showthread.php?t=304886&highlight="electric+turbo" <<<<<< here it is
