Calling all 3VZ-FE Owners!! Custom intake anyone?

[kmfdeviant530]

i got some pictures here of a custom intake that my friend designs.
first off I have to say, this design is Dyno proven on a 3VZ-E to gain 7 WHP on a 93 SR5 5speed pickup completely stock otherwise. dyno sheets are being searched for, the dyno was done about 4 years ago so we might have to re-dyno on both applications.
Now, for the seat dyno so far.
Im noticing a huge Rev speed increase, especially after ACIS kicks in, it rockets from 4200-up. the pull is sensational, i definately am noticing an increase of power. my MAF is 4 clicks lean, and i have a 2.5 Catback exhaust so that can have an effect on the outcome of the intake as well.
but overall this intake is designed to get air flowing through the tiny square with some force behind it.
I havnt discussed it with him yet, but since he is unemployed currently, he might go for making these and shipping at a cost to anyone interested. again these were dyno'd on a 3VZ-E and showed a gain of 7WHP on a completely stock motor and exhaust, so there is performance to gain from these.




Anyone interested PM me.

also additionally. we're making a mid piece to go between the TB and MAF to fit the lines going into it. for me to get it to work i had to chop off some of my stock intake to make it shorter.

acis kicks out around 3k.... the acis is only used on low end power.

seems like something they sell on ebay, so expect some flames on design

subscribed.

props for the custom work man.

I thought that these were proven to not gain the horsepower ??

I could be incorrect, but i thought I read that somewhere. I am interested in seeing the dyno results

Actually, acis is made "to promote low end torque" because the flap is closed. And then when it opens it helps top end. I was just Saying that after about 4200rpms when top end acis runners are being used it increases the rev speed enormously

[chronoti]

but under normal acceleration the valve is open, it will only close under high load at low rpm, so it's the system disengaging, and some guys trying to squeeze as much top end will remove the system (valve and divider plate inside the manifold)

but i would like to see the dyno with and with out the baffle in it (both with the cone filter)

Well, there is controversy on it. I knew about the dyno results because my ex boss, and my friend who designed this, dyno'd his truck before and after. And used spectres maf adapter. Spectres lame adapter produced 3 whp gain. This produced 7. They both swore up and down about it and at that point had dyno sheets. From what i have experienced driving around, this thing works wonders. I wont put a number figure on the HP increase but i do feel majorly improved throttle response and acceleration

What baffle?

I've seen similar. although much more beatifully designed little systems like this before (ever heard of Turbonators?). They supposedly intruduce turbulance into the airflow, which promotes better and more even cylinder mixing and burning. They are: discredited by any and all reputable testing sources.

Now just why would an obstruction to your air-flow, give you better power on a modern port fuel injected engine?

Well dr, if you understood this setup with toyotas MAF Its a square port. The main point of this design is that the adapter is matched in size with the MAF, and tunnels down to provide a smoother flow of air. Now, the blade design puts a spin on the traveling air, which thus makes it travel in a streamline going straight through the square instead of air funneling to the square.

I'll be the first to say I that I never had the patience to pursue a Doctrate level education, although Mensa was happy to welcome me, and I spent 8 years in graduate studies pursuing Degrees in Mechanical Engineer and Business.

These engines are not limited in power output by what they can flow, through one of the biggest MAFs that Toyota ever put on an engine in that time period. To get better airflow, you need to port and polish the heads.

Now, that being said, I'd love to see video of before and after dyno runs, with a reliable expert testifying that the results are from this device, and no other modifications.

If you can offer that you will get my big.

Well i cant confirm that i can get someone to take time out of there day to go on my dyno video, show theyre credentials, and tell you that info. But if i get the extra cash to dyno then i will video it and post results.

Props for making a custom piece, but on the 3vz-fe it wont really make much of a difference. Its a step forward though, leaning the afm and installing an intake will help but Silent Runner is right. The real power gains are in some skilled head work. Trust me, I know

Maybe you can sell it on an infomercial, maybe get a free "sham-wow" with every purchase.
