Electric Turbo

[david-b]

I've seen this on Ebay a couple times... It's a electric turbo. It goes on the intake, but instead of being ran from the exhaust, its hooked up to the battery with a button inside the car to activate it. Does this really work at all? It seems to me that there should be some increase, but nothing like a real turbo. Im not looking for massive h.p. increase, but I would like more. Would this work?

if its not driven by exhaust then its jsut a supercharger.

it might get you slightly above ambient and low rpm but you probobly wont see much at higher rpm.

I think those have been tested on a dyno, I believe the result was a small powerloss due to the restriction in the intake they cause. Many of them are just electric driven fans, which aren't suitable for the purpose at all.

Turbochargers use a carefully designed compressor and a turbine which even for small low boost engines can deliver a power which is several times the power output from the electric motors of those little things which is needed if you want to get any boost.

You can find real turbochargers from a couple hundred us dollars and up, buy the real thing instead.

I read an artical about a electric supercharger that's been developed recently that is actually powerful enough to be useful, but only for a short time...think nitrous. The guy's been working on it for...like...15 yrs or something because he's been waiting for electric motor technology to become good enough for what he wants to do. The ones he found to be powerful enough were way too big. I think what he ended up doing was using 3 smaller electric motors. He had the setup on his VW Bug for a while and said it worked.

Most of them out there are far too weak to do any good and I wouldn't be surprised if they actually did cause a HP loss.

I'll see if I can find the article I read about the good electric supercharger. You guys would probably find it interesting. I thought I saved it in my favorites, but I didn't.

Ahhh.

So basically, I should just buy a real turbo system or super charger for my Talon? That these are just hoaxes? Oh well Thanks

[longlivetheZ]

Most of them are b.s., yes. A turbo is the most efficient, effective power adder that you could put on your car...you're better off going that route than anything else, anyway.

if you are getting it for a talon why not go with a turbo 4g63 its been proven since like 1988 you can get a block for like $200 and a built head for like $300 more or less or just get the whole motor with turbo and accessories and just get it all on ebay

this is the only one ive ever even thought about being worth it. They have dyno sheets, and a money back guarantee. They claim 800CFM at 2 PSI. And its a turbo design with 50 some blades. I was gonna buy a nice new supercharger for my car, but i got rear ended and all themoney i saved this summer went to fixing it, so im thinking about getting this one. . .

If I could afford a new motor, I would get one with a turbo. However, lacking a lot of $$$$. I'm just doing "bolt-ons" right now. I guess I'll stick with that for this car. No major rebuilds. Should've just bought a TSi...

A roots blower will give the most bang for the buck. Way more than a turbo of the same size. The differences is cost and availability. Did you ever see a top fuel dragster with a turbo. Turbos were orginally concieved for diesel engines that do NOT operate over a wide RPM band. They gained popularity in cars back in the 1980's only because they made less noise than a supercharger/blower for the same boost.

forgive my noobieness, but whats a rooots blower?

[pro_am]

A roots blower is one that bolts on the the heads, like an intake, and you put your Two carbuerators on top of the blower. I think there may be an "intake" on the bottom of the blower to adapt it to the heads, but i'm not sure. The blower is belt driven.

A roots blower is one of the worst means of forced induction. The bulky roots compressor consumes a lot of power from the crankshaft and gives a high intake air temperature.

Top Fuels don't have turbochargers since they aren't allowed (as in most of the fastest drag racing classes), if the were we would see a powergain of about 1000 hp for a turbocharged Top Fuel.

How the roots works


Today lysholm screw type superchargers are often used instead of the roots which offers a better efficiency but at a higher price. The screws aren't allowed in top fuel either, they are however allowed in at least one of the faster drag racing classes but then they must be used together with a smaller displacement.

yeah a roots blower is less than 70% effecient whereas a turbo can be upwards of 90%. if you really want a supercharger then go with a centrifugal one. it has a compressor just like a turbos but obviously with different blade angles, sizes, and numbers. they are far more effecient that a roots blower.
