quick post before i hit the hay, a little idea that has recently brewed in my head. concept: to "charge" your airbox before a launch...

1. remove the small piece that connects the radiator holder to the air intake pipe.
2. bolt one of these on to the intake pipe: http://www.ebay.com/itm/Boat-In-line...s_Gear&vxp=mtr
3. use a manual switch (or a sensor that knows when your only in 1st-2nd gear?) to start / stop the blower

end result: the blower will "force assist" air into the airbox, resulting in more + cooler air entering the airbox when you are goosin it

thoughts? comments! lets hear em!

 

This is going to interesting with all the comments and answers.

 

good luck getting 3 inch piping to fit in a mini.
especially 8 inch straight section of it.
and really if you have the box vented front and rear, it will supply all the air your motor will require.
Sometimes more often than not, i think you are trolling us.

 

good point about the 8" length. i disagree about the 3" issue, a simple silicone reducer would take care of that.

to be honest, i have only recently heard this "trolling" term, and im not totally sure what it even means, at least in this situation... i am simply interested if any other modding engineers have thoughts on my ideas. i want them to either be proven, or dis-proven by others who have experience, knowledge, or insight

 

Calling a troll a troll?

 

First here is something similar (not in price) but it's meant for car intakes:

Secondly, here's why it won't work:

first, that basically is the same thing, just over priced, painted black, and a filter stuck on it. oh, and it comes with a switch :P

second, we already have a supercharger... that is what your first link says its for, "supercharging" your naturally aspirated car. so, thats exactly what we are NOT using it for. its not working on those hondas bc an engine will take in wayyyy more air than one of those can put out, resulting in restriction.

instead, i want to "assist" the supercharger by forcing air into the air box, making less drag for the engine (not only that, but cooler outside air). using the blower will not in any way hinder the original workings of the engine, as it would be placed in a non-restrictive situation....

 

believe me, i have much better things to do than devote brain power to pestering online forum peeps whom ive never met.

if i want to **** someone off, all i have to do is go to work

 

Even at idle your engine is producing over 20 inches of vacuum. This is enough suction where if you submerged your intake in water it would lift that water almost 2 feet above the ground vertically in your intake hose. This is why even idling though a flooded street can still hydrolock your engine, because all it takes is a little water to get sucked into the intake and within split seconds its inside your cylinder which has hardly 100cc's when the piston meets TDC.

So what I'm saying is this blower would have to be able to produce quite a bit of pressure for you to be able to pressurize the air box while the engine is at idle.

ALSO, you would never actually pressurize your airbox. By pressurizing your air box you would also be pressurizing your intake, your intercooler, your manifold and thus your cylinders. More air means your ECU would compensate with more fuel which means higher rpms. So essentially this would end up being a gas waster if it did anything at all. Even though the throttle is closed/partially open during idle I still doubt that much of a pressure charger would actually build up in the air box. And like said earlier, this ''blower'' would end up creating a restriction when the engine is off idle and accelerating.

Any sort of other inlets to the air box that may be actuated open or closed during this pressurization would be silly to have to execute with electronics and a control unit to shut the secondary inlet when throttle is at idle.

Honestly, if you wanted a better idea it would be something similar to an air pump used on air suspension systems, along with the pressurized storage tank associated with said systems. The pump could run whenever pressurizing the system so that it could blowoff the pressurized tank into the intake manifold activated by a switch similar to nitrous. However, again this would lead to issues with tuning where you would create a much to lean mixture and would have to compensate with additional fuel injector etc.

All in all, its just silly talk because this would all be much too complicated to execute with any meaningful results.

 

man you need to stay off eBay....

It seems it's the center for all your brilliant engineering ideas lol. Erik06MCS explained it well as to why its a pretty useless idea.

I'm with Colingreene on this one...some of these ideas are so whacked that I say to myself....he has to be messing with everyone. Not trying to be mean...but sometimes its just

A lot of us have been around these MINI's since they came out in 02 and have tried and/or seen everything possible with them. You're trying to think of complex solutions to things that either a) don't need a solution or b) have a far more simple and effective solution already out there

 

1. ebay is awesome. i have plenty of "ebay projects" that have / will turn out sweet

2. i have much better ways of messing with ppl, so you guys dont have to worry. i ask these questions and post ideas here Because you guys have been around the cars for 10 years now.

3. not comparing myself to them, but im pretty sure everyone said something similar about the Wright Brothers back in the day...

 

It never hurts to ask or try.

 

Astro, I love the thought that goes behind some of your "creations".

 

Me too. I've never met you, but I picture you as the guy from that 90's movie. Honey I shrunk the kids.

 

And I'm sure up to a certain speed that this would work. Like you said 1st/2nd gear. After that I would say it would be useless seeing that eventually the speed you are going would move the air into the air box faster than the blower. I could see this being semi useful in drag style racing or maybe even using the blower to move the heat out of the engine bay during slow traffic situations. With some stratigec placement of course

 

1. Cut hole in hood, cut hole in airbox
2. Mount a pusher-type of one of these in the middle of said hole under hood, on top of air box
3. ???
4. Profit

 

Not into cutting up the hood, but on the right track. Maybe make it pull air from the cowl instead. Do some sort of mod to go between the airbox and plastic cowl peice?

 

isnt all this what a turbo is for?
