What do you mean hilarious, I put them on my new 2012 Lariat ECo and it now gets 35.2 MPG and I had it dino'd its producing 580 HP@ 4600 RPM and 635 lbft torque @ 2850 RPM.

I am thinking of doubling them up for more increase......

I have 3 of them inline on my 02 expedition, i run 9's in the quarter...

I really wonder what these things do though. I saw on the page that 30 of them had been sold, so they gotta work right?

you guys can't be serious. I'm ready for more internet knowledge .

If you believe that, I have a bridge that I would like to offer you for sale at a discounted price. But to clarify, no I dont have an expedition that runs 9's. Maybe 9 minutes...

I have read thru the hole thread... and I haven't really seen any one talk about it..

From a Aircraft Mechanics perspective... in relation to these parts...1. look at what is up stream from where these are located in the system.. they are directly after the Y pipe and flexible section of pluming.. logic would dictate that they put them in the system in an attempt to straighten out some of the airflow before entering the turbos... 2.. For the difference in the size of the pluming going to each turbo... Air like water likes to take the path of least resistance.. The right turbo has more of a straight shot threw the y pipe then the left turbo.. and the ratio in size is an effort to keep the volume of air going to both turbos the same after the Y.. just an A&P's thought on the subject..

We've moved on past the subject of why air flows through a tube with lower air pressure than outside it, toward the turbo much like water drains down a drain. We are now designing a twin turbo system with an air induction design to the turbo's that's perty much a straight shot to the turbos and a programing/driver for the puter to operate with 2 mass sensors. Note you don't see square tubes in air induction systems unless they have a round insert inside of them. The twirly things are an engineering fix for the fu__ed up design. It's pure Genious ! LOL On a short note my 3.7 burned 1.3 gallons of gas an hour this last time, with 12.5 gallons of shell 87 after 9.5 hours of cross town expressway and stop and go driving with no warm up time and little idle time except at the stop lights. What are your EB's using an hour ? I'll start a thread if I get time. I had a 4 cyl car that got 36mpg. since new, and after 4 years was averaging driving 44 mph and using just over 2 gallons of gas an hour.

I thought I mention very early a comparison to a turboshaft engine. I also am a A&P just non practicing.

No, impossible to be flow restrictors. They're guide vanes, in order to induce a swirl (spin the flow how we want it) or they eliminate any incoming swirl (again, to orientate the flow how we want it)

I can only imagine the bad thoughts going thru the pilots mind of the Harrior when he hears that popping sound thru the turbojet. :wheelchair :
