UK-POLOS.NET - THE VW Polo Forum

Just found this whilst browsing the internet, dunno if any one has posted this before but do you reckon this acctually works?

From what i gather its exactly the same as an induction kit but with an electrically driven fan to cram s**t loads of air into your engine... sounds like fun but im not hot on this kinda thing.... opinions?

EDIT: never mind lol, just found out you get like +6%hp and for £300 and much less mpg its a bit poo

Quite frankly, no little electric fan is going to be able to push in enough air to create a positive pressure. If anything it will be a restriction that reduces your power!

hmm i dunno, the dual one seems quite powerful and spins considerably quickly but its expensive for the small gains it produces

belt driven superchargers and turbochargers have actual compressor blades spinning at 80+ thousand rpm, They are precision designed to withstand the forces involved.

These electric supercharger things will spin at 25 thousand rpm at their absolute maximum, and are spinning a plastic fan blade.

So I doubt these things even generate 0.1bar of positive pressure.

I live in Johannesburg, which is at a power sapping 1700m above sea-level. Normally aspirated cars lose anything from 15-20% of their power, even turbocharged cars lose 5% of their power.

Now don't you think if these things really worked all of us Joburgers would have them installed in ours cars. We don't, because these sorts of gimmicky things just don't work.

Saved me typing anything - thanks

Perfect........ Waste of money all these bolt on gizmos

80+ thousand RPM? Are you sure?

G40 chargers spin at 1.6 times engine speed as standard, that's a high revving engine.

There's a full thread on the Pitstop Developments forum about electric superchargers, it's worth a read.

lol i did think they were a bit poo

id try one if they were like £30 but for that sort of money its really just another scam i spose

a proper charger conv sounds like a laugh tho even tho pointless on my car lol

Yes, your right about the G-lader (but other superchargers are available ), i think he was generally making the point about turbochargers, in which case, 80k is the norm, 150k+ is not unknown

file them under the same category as the "power boost valves" that give you up to 70 extra horse power (yeah, right, how big's the horse?), ready-made chips on ebay, and all manner of other dodgy "tuning" parts whose makers scam chavs out of thousands on a daily basis

seen a couple of rather chavvy cars being sold on the works messageboard with such things included in the description!
