do i just unbolt the top half and remove the plate? if so do i need to replace it with another gasket or what have you guys done instead of the gasket

is there any bad things that can happen by removing the plate?

 

why do you want to remove the secoundary butteryflys?
you will losse low end power like a ****

Removing it is pointless. You just loose low-end power....search.

You will likely have to pry the plate up if it has never been taken off before. Just use a flathead. I used hondabond to reseal it since i fubar'd the gasket.

You will have to remove the studs and replace the studs with properly lengthed bolts.

 

i forgot to mention the car is boosted, wouldnt this help more than hurt in my case?

 

when your boosted you want a larger plenum size in the intake, instead of taking out the plate just remove the butterfly valves and the rod and plug up the holes. or get with blacktrax and get their replacement plate.

the IAB plate is technically part of the runners, not of the plenum.

a new oem gasket is like $7, just be sure to scrape the old one off completely

 

ah but wouldn't just removing the plate reduce the volume

 

yes the volume of the runners, not of the plenum

 

most of the FI IM's i have seen use short runners and large plenums so technically i guess it would be helping your situation.

I'm still working on getting some kind of analysis on whether it helps NA.

 

so would is it just a 'give and take' with taking out the whole plate instead of just removing the butterfly vavles?

 

??

 

honestly can someone show me what a butterly plate or butterflies cause i have no clue what this is i feel sorry for myself

 

Here's the only pic I have right now...hope that gives you some idea. There's 4 butterflies and 4 runners inside this plate.

 

For a turbo car you would want SHORT FAT runners. With a turbo your only concern is air flow capacity. For instance...



A manifold like the one about would be perfect for a turbo application. There is less distance for the pressurized air to go thru. This is made by edelbrock for turbo cars. Now a manifold like this one...



Also made by edelbrock is geared more towards N/A builds with long narrower runners. For NA cars you need flow velocity and thus longer narrower runners. Moral of the story if your going turbo, the shorter & fatter the runners the better.

ehh...the old long shorter runner trick huh??

lol

 

those manifolds are for different cars. b18c vs a d16y8
you cannot compare those manifolds

 

but on ebay i seen a vector x manifold with a prelude flange welded on to it
i should have bid on it

Voila...When it's the truth yes

I know that, it was just a general statement about IM design.

 

removing the butterfly plate will reducing throttle response since you are decreasing the volume of air in the IM. For racing app its fine since your usually @ WOT but for a DD its best you leave them there for low end torque. Unless its a race vehicle you will not benefit. Its all about volume.

 

wouldnt less volume = faster response since the air is able to travel from the plenum to the combustion chamber in a shorter distance?

i have noticed absolutely no bad effects of removing my plate, that i can feel.

lol read what you said.... long shorter....lol

fastwanabe, don't pretend to know anything about airflow dynamics, please, just keep your (wrong) theories to yourself from now on I'm sick of people making up some BS about what they think modifying a manifold does when they really have no idea.

without butterfly plate


with butterfly plate

Apparently you think you know what you are talking about so how about you enlight us all on the subject.

explain your reasoning against mine.
