The Blade - Increase Fuel Economy by 30%?

[elhigh]

Awright! A Tornado for the ass end of the car! WooHoo!

Now I can have a economy gizmo that sucks...and another that blows!

I'll keep the money that the thing costs and go buy some coroplast, mmkay? 'Cause I know that'll work, and I don't need BS "tests" to prove it.

I spit out like.. three pallets of paper clips a year ^_^

Hee hee hee, that's what I was thinking. You can glean the construction from the installation manual :

What I didn't notice previously is that there are "two" exhaust ports. The first is the "griddle" end that creates back-pressure, but the second is the filter. There is a triangular cut in the tube that exposes the filter to the outside. When mounting, you aim that open part down. Therefore, the back-pressure must help push exhaust through the filter, aiding in PM capture.

You should donate them to the SSFA, the Stationaries Supplies Fund of America, !

EDIT: It turns out that it that they make one for your MBenz :

I'm the guy that started the other thread.
I just can't seem to get up the drive to find find out more about this thing.

I just feel it's all a load of crap, and they are trying to use a good cause to cheat people out of their money.

If I ever do get around to it ( most likely not ) I'll have to invite the maker of this thing to back up his claims by letting one of us test it .

It causes increased backpressure.
The increased backpressure causes more exhaust reversion during overlap...
I'm calling snake oil LOL

The snake oil salesmen are out in full force these days, aren't they?

"I can take your silver and turn it into gold... give me your pound of silver and come back next Tuesday..." For me though, I'm glad these guys are around... It prompts the learning of things I never would have, by questioning the claims. On the other side, I hate to see good people get suckered into some scam.

Increased exhaust back pressure can, in some instances, net a power increase. I've seen this on some normally aspirated race engines where the cam has a little too much duration, or the primary header tube is too large causing the exhaust port to over scavenge (draws some of the fresh intake charge, unburned, out the exhaust port). One 4 cylinder race engine of mine picked up a full 10hp at 7500rpm when we added a muffler. It's likely the exhaust to intake ratio of the heads (ports) didn't quite match the cam I chose, but it was amazing to watch while dynoing the two exhaust systems, back-to-back in A-B-A testing.

Hello -

Saw this last week :



Cellphone camera, so the image is bad, but those are definitely blades.

Treehuggers had an article on it:
Is This the Most Eco-Friendly Car Innovation Since the Hybrid? : TreeHugger

Also it seems like the California Air Resources Board is a believer...

[some_other_dave]

If they (CARB) list it, it merely means that the manufacturer went through the testing process and showed that it did not adversely effect emissions that they could see. Nothing about it actually working as claimed in any way shape or form.

CARB doesn't care about saving gas or improving emissions, they just care about not increasing emissions.

I'm currently writing a rebuttal for EM, seems the Blade didn't take lower school math classes...
