Has anyone tried one of these... 020QQitemZ300041271354QQrdZ1QQsspagenameZWD1V

Wondering if it is just a piece of crap or would make a difference?

beepbeep 11-20-2006 12:39 AM are kidding, right?

It takes 20-30 horsepower to do any sort of meaningsfull pressurization. That's around 20kW of electrical power. 20kW of power from 12V is ~1600A of current.

If you know a thing or two about electricity you will know that wire gauge that transfers 1600A is very very thick. And I'n not even talking about demand on battery. So yeah, it's crap all right.

Try to imagine a eng running at just 3000 try to imagine the lil electric motor tyring to fill the cylinders at that low speed...esp with boost on top of it................get the picture ?? cant happen. could not even do one cyl ...could not blow a fart off a ant

Hmmm 2.2 amps at 12 volts equals 26 watts or .035 HP.

In an old turbocharging book by Hugh McInnes it mentions that it is not uncommon for a turbo running at full song to actually develop over 100 HP measured at the turbo shaft. I have no idea if this is true, but 100 HP equates to about 75,000 watts.

That thing would just end up being a restriction.

I put one of those on my car and I dropped into the mid 9's in the quarter mile with it, the response is unbelievable. I was going to go with an ATI procharger, or a roots blower, but I figured instead of spend the money Id try this, what a differnce! As soon as I pulled out into traffic and hit the gas, the car lept forward with ferocity and went sideways (I have an AWD twin turbo that I took the turbos off of just so I could run this unit) the added benefit to this also is that my girlfriend and I went on a road trip a while back and we wound up sleeping in the car one night, and in the morning we had to poop in the woods behind trees, and bath in a creek with a bar of lever 2000 and wildlife watching us, and she was all pissed becasue she had no way of drying her hair after the bath in the stream, so in my clever witty way of appeasing her, unhooked my supercharger from the motor, and she used it to blowdry her hair, she was so happy. I also have been using it as a leaf blower to do my driveway, walkways, and lawn until I can get my tail over to Home Depot and buy a backpack blower. I plan on using it to blow up all my inflatable pool toys next summer when the weather gets nice, so Ill let you know how it goes.

I actually saw one on a Honda that had a chance to work. It was designed for a 1.5 liter engine. I think that is important (the size of engine) since current draw and amperage is somewhat limited in an auto design. NO, nothing like the above which is junk.

This design was built by some EE guys. It was a drag racing specific application that could only hold boost for something like 15 seconds. They installed an extra battery, 2/0 wires, and kept everthing in close proximity. Keeping it close is important since voltage drop over a wires length and cross section are relative.

OK enough delay: They used a positive displacement roots style blower of adequate size for a 1.5 liter engine. They drove it with three gear driven 5hp starter motors. So this yields about 15 hp of blower drive which if geared correctly could/should make some real measurable boost. Some may doubt this could work either....I certainly doubt the above stule in the auction, but in a limited narrow application it might be possible. It would certainly add a lot of weight.

E-RAM! It's guaranteed! :cool:

It levitates! It blows Duraflame logs!

I was buying it until you said you actually slept in the 996. :rolleyes:

garibaldi 12-02-2006 07:14 AM

Well, to correct you, it was actually a 993, much more roomy and cushy, with seating for 7 grown adults....:D

Plus that e ram was sold when I saw the duraflame log get blown around....and the garbage bag demo, well Id need to see if they were using hefty cinch sacks or a generic store bought garbage bag to really be convinced....I was on the brink of dropping the $500 plus dollars on the twin system when I realized that there is a holiday price break on CONAIR hairdryers at CVS right now, for $19.99 each, so Ill try those first
