The "Poor" Man's (or Woman's) high flow air intake

Is this a paid commercial?

 

OK.....
Then what?

Priuses have a closed loop fuel injection system, and they're electronically throttled, so other than making your ICE a little louder and perhaps cluttering your engine bay a little bit, I'm not sure what you're actually accomplishing.

 

The biggest flow restriction a Prius has is the 1.5 liter part.............or I suppose that would be 1.8 for some...

I also highly recommend the electric turbo fans being sold on ebay. Worth at least a 20 hp improvement and 13 additional mpg.......
There's apparently already at least 54 fools in the world...........

To be fair, most of the folks buying those are probably not Prius drivers....

 

Arent those intake fans totally worthless.. There was some youtube review of those and they even tested with massive leaf blower with zero help even from that.

 

Worthless only to those who don't believe....lol. That should be just about everyone, except those that purchase it...
Very worthwhile to those selling it...$$$ in pocket
Very worthwhile to the mechanic that replaces the engine when a blade breaks off and chunks a piston

 

I'm going to have to think about this for a while.............my brain is starting to hurt

 

There may be a slight difference in engine noise between resonator on/off but I haven't noticed it. I took mine off to make room for an oil catch can. The benefits are mainly more real estate for an OCC and fewer steps when removing your intake.

FWIW, but most people need to pass emissions inspections.

I don't see a high flow intake installation/modification.

 

I did it because it leaves me more room for oil catch can

 

Seeing as I am unfamiliar with the V model, I'm assuming the flexible hose at the center bottom clamps to the throttle body. Where does the red circled portion connect?

 

Adding an oil catch can is a good 'get' for removing the resonator, as long as you do not live where VETs don't help animals.....

The rest?
Well as I asked before....."now what?"
As I said before.....It's a closed loop system.
As pointed out above, if you don't ALSO uncork the exhaust and then find a way to deal with the ECU then you're just kidding yourself if you think that there will be a net power or efficiency gain that toy don't need a dynamometer and a set of calipers to measure.

Remember.....this isn't 1973.
You can't flip the breather, re-jet the carbs and bolt a set of headers on the car to get measurable horsepower gains......and LOOK AT THE G4!!!! If they had to do THAT to a car to get a 2-3 MPG difference, don't you think that they would have thought about just taking off the resonator, using a leaf blower, or any of the other zany stuff out there on a car that is marketed for fuel efficiency?

 

I don't see how this portion (marked in red) would be restricting air flow, at least not in a significant/measurable way. It's purposes I think are to get cooler air supply, and lower noise levels. I think it does both those things ok. Removing it is chasing crumbs, I'd prefer not to second-guess the Toyota engineers on this.



For what it's worth, I tucked a Moroso oil catch can in, and managed to keep everything looking stock. I mounted the can on a bracket atop the lower cross beam (loosely mounted, so the beam can flex). When you pop the hood everything looks completely stock.

 

When I open the hood on my Gen4, all I see is COMPLICATED! I don't want to do anything more than just checking the dipstick, and popping in a new air filter.

(And WHERE is that wire harness recall thing located??! )

 

Looks like the cat turds cleaned up good, looks sharp.

I'd speculate this the beginning of the air intake:



The intention seems clearly to pull in cooler outside air. Not much upside to messing with that.
