| Guys, I was just surfing auction sites and came across an electric Super Charger. Just wondering what your opinion of these units is. If it does everything it claims (which i doubt) then it's a pretty cheap and easy power upgrade for $250..

| Your timing in impecable!! I just posted a response to a the same question on this thread.. http://soarercentral.com/sc-forum/messages/121829/61225.html?1211423004 |

| It seems they have become trendy in the last 24 hours. Basically it isn't going to work. Think about what size electric fan (and that is what it is) would be needed to keep your 4 litre engine happy at full RPM, and then to increase the pressure to improve performance. Then think how much current that would require if it was possible, and how much of a load that would put on your alternator. A few weeks ago a link was posted to a video showing a guy testing one on a car (non Soarer) and his vacuum/boost gauge showed NO change at all. |

| Thanks for the reply Peter/Tai. I can see what you mean, however I still not convinced (either way). I have been looking around and there is a mob in Qld (called Force Flow Racing) who seem to be making gains (and on large capacity engines too). They have a kit car running a 3.8Lt Commodore motor and a 5Ltr V8 Commodore that are both fitted with their hair driers. I think it's worth keeping the debate open so I have emailed the distributor in Queensland (and provided the link to this post) so we'll see what eventuates.. The website i am referring to is: http://www.force-flow.com/ and the pics of the 5Ltr V8 are here: http://www.force-flow.com/racing002.aspx |

| The web site is pretty short on facts. No mention of current drain for example and the resulting load on the cars electrical system. In fact about all they state, is the air flow as x cfm depending on the model, and up to 4300 RPM for the top model. CFM may work in free air conditions, but it's very difficult to make pressure with an electric fan, try it sometime. From Wikipedia about car turbos : "A turbo spins very fast; most peak between 80,000 and 200,000 RPM (using low inertia turbos, 150,000-250,000 RPM) depending on size, weight of the rotating parts, boost pressure developed and compressor design." Real superchargers use things like vanes etc to make pressure, they actually have to grab some air, squash the air, then pass it on and grab another lung full. |

| Thanks for the insightful post Miles. I'm not for one second advocating these devices (especially the ebay one that started this thread). I'm merely asking for educated opinion. There are photos of cars on race tracks using the force-flow devices, so until someone shows me that they are photoshopped or made up purely to rip people off I can't help but think that some positive pressure is better than none at all, especially at low RPM. |

| You got my opinion. There is no case for keeping the debate open. There is no debate. If I made a web page showing a (real) dog turd taped to my motor, and said it made +10hp, would you believe that too? |

I really hope you're not having a dig at me David. This is a FORUM. Which implies discussion not ridicule. I clearly stated I am not an advocate. |

| OMG not humourous jibes on an internet forum?!?!? What is the world coming to when you can't even trust people on the internet to be absolutely polite at all times? Next you'll be telling me those dick enlargement pills don't work! |

| Look I'm no idiot, but I have clearly put my foot in it this time. I concede that it is all total BS and I'll accept all criticism and ridicule in due course. For the record I thought the thing about taping dog sh*t to a car and making a website WAS pretty funny.. Oh and Miles, the dick enlargement pills aren't required. It appears that lately i've been making a rather big dick of myself without any need for them.. To think, I have rebuilt engines before..

| Also David, the reason i responded how I did was that Miles' original post (which I read in email) made no mention of the turd thing (he must have edited his post), so i thought you had just jumped in from left field with your reply..

| While I stand in the same field as Muzzy and Miles on the likelihood they might work, I am happy to see questions asked and answered. As Peter said, feed us their replies so we can see what they say. I notice that each of the installations shows a pod filter (probably more pod than filter) or in one case a ram air intake. If someone fits a turdocharger to their car in lieu of the stock intake, they are certainly going to get a real improvement in performance. It will just have a lot less to do with the turdo than they imagine. |

| Well I still have a stock intake, so I could save myself the hassle of making a free BFI simply by installing the Force Flow 8.0 Twin side by side Electric Intake Supercharger System for only $629.00 (GST Inc)
Please note the 8.0 twin system requires a y-join to connect the 2 electric intake superchargers to your intake system. The y-join is not included in this kit as it should be custom fabricated to suit the space in your vehicle. I might need some help with that part though, perhaps another Fix-it day would be in order? |

| Or you could go down to the local computer shop and pick up a pair of the exact same fans for <$20. I'd hate to see what happens when the fan fails and it gets sucked through the engine because it's mounted *after* the air filter. I guess that's covered by this from their site: Realm Enterprises (Global) Pty Ltd and Force Flow or any of its employees can not be held liable for any damage caused to a motor vehicle or any of its parts which has had Force Flow products installed. |

This is my main gripe for the things... Even if they do work even slightly, you could get a decent exhaust and intake mods for that price and probably get way more than 20hp gains.. and for a few extra bucks a uni chip or similar.. There is no need to flame Mark, there is no such thing as a stupid question. Just give your thoughts on the matter in a civil way |

If you then had pictures of that car on a race track on your website, i'd be inclined to believe... hahaha /End of thread |

| Couple of months. Nice too, but I love them both, so very different to drive. The 31 is a super smooth cruiser, while the 30 is more for hooning. |

| Mechanically-driven superchargers on road cars consume anything from 15kw to about 75kw of power. Simple arithmetic involving volts, amps, and watts tells you that a piddly little electric fan is not going to work This is an electric supercharger which does work http://www.turbomagazine.com/tech/0406tur_knight_turbo_electric_supercharger/index.html Spot the difference? |

That's more like it!! Looks pretty heavy with all the batteries though.. It's hard to beat liquid fuel for power.. |
