i have never even heard of an electric turbo...how many different types of turbos/superchargers are there? 8cd, you were saying an exhaust driven turbo....is that the one i generally think of when i imagine a turbo or is that different?
and not to be a post jacker, but what is the difference between a supercharger and a turbocharger?
Let me answer that. turbocharger = exhaust driven. supercharger = belt driven, roots or centrifigual. Right 8cd?
yea. There are 4 general types of superchargers. Turbocharger, twin-screw, roots, and centrifugal. There are more, but those are the main types. The turbo is the only one not belt driven. I did a big write-up on this with a guy from the cobalt forums on their site. I'll get the link.
"• Battery technology and weight are the classic detractors. However, battery technology has advanced significantly in recent years and the lightweight batteries that are available already will become lighter as the technology evolves."
"12-20-03 Moroso Motorsport Park was home this weekend to the Sport Compact Winter Challenge, and we took the Altima to MMP to test the ESC down the quarter mile. The weight of the car with speaker box, molded body kit, ESC-400 and batteries, etc was 3,780 pounds. The stock KADE 2.4-liter four-cylinder automatic ran low 18s at 78 mph with the ESC off, and ran a best 15.583 at 89 mph at only 5 psi boost. Traction with the ESC was a real problem, with 2.45 60-foot times on four attempts. This is faster than a 5.0 Mustang convertible." "1-6-04 Installed the ESC-400DR-550 (drag racing version) in the Altima, prepping it for Moroso on February 8. This unit is capable of 20-plus psi, so we had to set the pressure to 10 psi with the BOV. At 10 psi, it feels like a high 13-second car, and we'll add some parts to support the 10 psi. We're installing headers, an exhaust system and larger injectors. A dyno run is set for next Wednesday at South Florida Performance. We should see well over 200 whp on this stock long-block auto trans Altima."
Not too shabby. I wonder what the system cost is/was.
Interesting shi*..
Has anyone seen the glorified blowers on ebay? Very suspicious! Do a google for 'electric turbo'. Weird!

Correct me if I'm wrong but, wait a minute, what's the difference between a roots charger and a twin screw supercharger other than where they build boost? I thought roots was more the style of the thing than anything else? Even though one bolts up to the intake ports (replaces the intake mani') and the other bolts to the intake mani', they are both still roots chargers right?

Actually I goofed there. How they bolt on is irrelivant. One uses a screw and the other (roots) uses paddles. Roots chargers are cool because they stick out of the hood. They are also HUGE heavy monsters. They also deliver boost in successive bursts where the screw charger is much smaller, lighter and delivers boost in a smooth progressive and instantanious manner due to their ability to build up pressure inside the screw channels or grooves before discharging out into the engine. Pressure /boost is already there from the gitgo before it even hits the cylinders. Heat soak is less of a problem in this case. The roots (paddle type) more or less puffs pressure pulses into the engine and it builds up inside the intake mainifold and intake ports. Therefore heat soak is obviously more of a problem with a roots charger. Not only are they different from a visual / asthetic perspective, they are evidently miles apart in performance and efficiency. Vally intelestink!

ive been browsing over the net has anyone ever tried the eletric turbo just wondering if they acually work?
Do you really want to run the very real risk of having something on one of those elec-turbos breaking off and going straight into your motor?? How much boost is an electric turbo going to give you? Not what some caption on their website says about 10-15whp.... But REAL numbers? If you've got money to burn, then go ahead and tell us all how they work. Everyone I've talked to says those things are 100% junk. Right up there with throttle body spacers that give some kind of magical swirl that boosts hp.....
Yeah but I bet they're more thermally efficient than an X-Charger!

well technically, a turbocharger is a form of supercharger, but yea. If you look at the link you gave us, you can see that he has 6 batteries in the trunk, all about half the size of your average car battery. Depending on what kinda battery they are, thats most likely between 150-200 lbs of extra weight. Then the head unit and all the extra hardware in the engine bay weighs probably 100 at the very least with all the modifications he has done, so lets say there is a weight addition of 300 lbs at the VERY least. It is just far less cost efficient for the performance increase. I have seen these before around the internet, i know there is a 300zx with an electric supercharger somewhere in texas. It's a cool idea, and im sure someday it will be the way to go, but right now it just does not work as well as a conventional turbo.
