Title: Maybe stupid idea? maybe not.
Post by: Khare on 02 October 2009, 13:45
Right, I have been thinking about it in the past, and it probably is a stupid idea and you will laugh, BUT, in theory, it SHOULD work.

/Flameproof suit on

I have an old vacuum cleaner motor along with it's switch and the cable. I have tested it and it works perfectly. Now my theory is, if you mount it on the air box, using a power converter (which I have, 12v-240v) to power it, and then run the switch in the cabin to turn it on/off, do you think it would make any difference? In theory it should, as it is filling the air box VERY quickly with nice air. Like an electric supercharger style.

Views please.

Doubt it.

It might cause a build up of air pressure.  Engine might not run rich enough.

Give it a go though.

will only work if you put helium in your tyres at the same time.

If you try it, make sure you upload some pics. and show the test results.

noooo he doesn't want Helium he wants Tungsten Hexafluoride  :evil: Just don't let your tyres get too cold otherwise you'll have a sloshing in your tyres  :laugh:

If you run the vacuum from an intake in the bumper somewhere then you will get nice cold air. but not if its just sat on your air box sucking up your engine heat.

wait a minute....helium is lighter than air.....lightweight wheels reduce unsprung weight....see where I'm going with this?  :grin:

Obviously I'd have a good cold air intake running to it, both for cold air and to keep the motor cool.

I'm gonna get hold of an used air box and try some ideas and do some planning, I'm interested in what the results could be  :smiley:


Quick question. The power converter has a +ve and a -ve wire, can I run them straight to the battery terminals without fusing it? or should I fuse it?

You are due another eye poke for that!
Title: Re: Maybe stupid idea? maybe not.
Post by: Khare on 02 October 2009, 14:07
but think about it.....

When stopped, there no current of air in the air box, so the air that is sucked in by the engine is minimum. If suddenly the engine has a whole load of air available to it from 0mph, then my guess is it will pick up much better from a standstill.

No idea. Tested it though and it does flow a lot of air.

Car is DC Hoover motor is AC, what is your convertor? is it an invertor?
Yes use fuse's and have a fire extinguisher near by :evil:

You can actualy buy 1500cfm 12v DC impellors from RS/Trade specialist suppliers which will fit into the front of an 8v air box, i have measured it (Just like a large computer fan).
This draws 80amps from the battery and can be controlled like electric Electric S/C kits from the go pedal.

Best bet is to buy Mikesters spare 8v lump and fit it into your boot and call your golf a valver :laugh:

why not just spend £100 on one of these lol
may make a small diff, should check airflow as may not have enough for high revs full throttle

Khare bear just admit defeat and buy a 16v!  :grin:

This rates as a close second to you playing with your ECU week before a Rolling Road AND with a naff chip off ebay!

f**k me, I thought you were sensible.   :tongue: :grin:

No it's not going to do much at all.

It already has "air" in the airbox. It get's it from the engines vacuum. This motor would generate loads of heat so it would have loads of hot air in there and it could REDUCE airflow.

The airbox wouldn't hold any pressure so no forced induction. It wouldn't work. I see what you are getting at, cold air feed at standstill, well a heat sheild'd induction at the front could do this but it's pointless.
