Is there such a device that would enable to have the supercharger be turned on or off at will? I would love to have the power when you want it like a shot of NOS, but wouldn't need it all the time since I am a daily driver with my Max.

 

Well if the Supercharger is what takes the place of the intake, how would you get air into your engine ?

 

Like I said, I was just curious if this had become an idea to anyone. I personally would have no idea how to make this idea work.

 

project anyone ???
there could be a way ... couldn't it work just like the thermostat works ... when you want air on your feet you press the feet button when you want the air on your face you press the face button ..... this could be the equivalent of having the air come through the super charger, or a filter (there would be enough room for it) ...

 

It would have to be designed for it... Using an electromagnetic clutch like that on the A/C compressors and then you need to integrate an air bypass as well.

The BOV sort of does this... at high vacuum... it bleeds off the extra boost so the S/C doesn't work so hard.

 

I was actually thinking about something along the same lines, but completely reversed...

I am into RC cars and there are two speed trannys (and even 3speeds) available for gas powered cars.

What I was thinking was having some sort of system to increase the SC speed at low RPM to get the maximum boost and then fall back to normal at crusing speed. Kinda like a 2.8 - 3.0 from 1000 - 3000 then it falls to a 3.2 or something like that

 

Heck! Might as well go all the way.. make the whole thing electric and NOT belt driven Some one suggested a leaf blower before

 

Yeah your ignition key will turn it on and off...hehehe
Daniel B Martin and I had a lengthy thread about electric blowers, non leaf type. We spoke to vendors all over North America about the requirements needed to move enough air to provide 10lbs of boost. The problem is that the current technology is too expensive. there is a company in NY that said they had a 5 inch blower that could move that air mass but it was like 15k and had a short life expectancy(like 3 yrs) I guess it was designed for the space shuttle, I don't know. but We explored a dual blower system with cheaper components, but it required like 36 volts to run. the technology is there, but its just too expensive to make a quality electric blower thats less than 5 inches in diameter that can move 200,000(or something crazy) litres of air a minute and only run on a 12 volt battery. We did come across an electric S/C thats being marketed to boost 3psi for 350bucks or so.

 

i've seen the electric s/c. while i don't want to believe what they say i saw it not only levitate itself but try and straight up fly away and move a dura-log with ease just from airflow. it's iffy though.

Crack Mack: WTF you smoking?!

SLC I30t: There was a thread on those a while ago, basically the conclusion is that the electric supercharger would melt itself before it could make 3 lbs of boost =P.

Chunger: actually a BOV is there to relieve the backpressure that suddenly occurs when the throttle plate closes. This prolongs the life of your supercharger and allows it to remain spooled between gears. That's why you hear the PSHHHH when you let off the gas, that's the blow off valve opening and bypassing the excess boost that would otherwise back up and work against the SC.

My idea for an on/off would be simple, install a wastegate type device that just vents boost when you want it off and hook it up to a boost controller. Voila.

 

yes but that way would have it always turning and stressing your engine with no gains. you would have to run some boost to get power back, the a/c clutch idea is a good one

 

My SC'd Max is my daily driver. I hardly ever race although I occationally go to the track. My drives normal, but the power is there when I want it. All I have to do to utilize that power is to press on the accelerator. I still have my fpr switch hooked up the the vacume line so the fuel pressure in under pressure only when I am under boost..

Come to think of it, it has been a while since I've seen my boost gauge on the positive boost.. By the way, my car dyno'd at 277fwhp before my latest pulley swap. And that power is available to me immediately or incrementally.

=)

 

I have an HPI RS4 of an altezza and an A4.

 

that good ****.....

 

Just don't floor it... no floor = no boost = won't waste gas

 

any of you rc guys want to buy a airtonics m8 radio 2months old...

 

That's the primary function but on our S/C kit it does as I state also...The BOV bleeds air out at high vacuum.

 

yeah, but it might be cheaper =P

besides you don't need much power for just cruising around and boost is just a push of a button away...

ur right though you might lose gas mileage..

 

I think someone's been watching The Road Warrior!

Remember that vehicle chase in the very beginning where he's got that red button in the car to clutch/declutch the SC on the engine? That was cool!

 

hell yeah...he pushed the button, and all you heard was that high pitched "whine" and he was gone ...of course the effects kinda sucked back then though and the car was really only fast forwarded on tape(ala The F&F)!!!!

 

Why in the world does no one use mechanical advantage to run the super charger more efficiently? Using a substantially larger wheel on the crank and a very small one on the charger shaft would speed it up alot! Granted, it would rob more horsepower, but you could easily make up for it by increasing fuel pressure, etc. As far as the whole electric supercharger idea goes, it should be cooled just like a turbo, and be fed a larger amount of electricity run the motor faster. I have a theory that curving the blades on the "fan" and having more than one "fan" on the shaft would increase it's air flow capabilities. I really think this can be done, it just requires some engineering. I think I'll start to build an electric supercharger that will be better than even a regular supercharger! Wish me luck.

 

The only problem with overboosting is that you increase cylinder pressure. At one point you have gaskets splattered all over the inside of you engine bay. Or else everyone would be running a .00001 pulley.

 

I guess your going to apply solar cells onto the roof of your car?
Go ahead and do your own research, we'll talk when you find out what Daniel B. Martin and I already have. Good luck

 

the stillen unit does coem with a larger crank pulley, but you can only make it so big.

I don't see the point of doing this. The wole point of a SC over NOS is it is always there when you want/need it. If you drive your car like you normally do, you will hardly even know the SC is there. It's not like you just touch the pedal and you're pinned to your seat-back. It only kicks in under full throttle/high RPMs. I get mid-twenties m.p.g. on my daily driver.

 

uhh this topic makes no sense. if u want speed only for a little while then get NOS.

 

Ecchhhoooo... ecchhhoooo... ecchhhoooo...

 

some of you have the most creative ways to ***** a thread. Kudos

 

 

Why doesn't it make sense? I was just curious, that is all. I like the idea of a S/C and NOS, but the problem with NOS is that you have to fill up the bottle to keep it going. I thought I would check on the idea if this on/off switch had been explored at all.

 

Rather than an actual on/off switch, I wish there was some kind of an option for say a boost controller. You could run some insane size pulley like 3.0" but turn the boost down to 5-6 for everyday driving. ???
