I can just pull the top half of the manifold apart, and take out the plate along with the IAB's, and put it all back together, right? if not, whats another way to take them out? for the mean time, what do you do to make sure their open? From what i found, putting a straight vaccum source on them keeps them open, and it went faster this way anyways...

 

dont you just pull the line off the diaphragm to keep them open?

 

If you take off the vacuum line on the gold colored valve that sits to the right of the plenum they will stay open. A vacuum signal closes the butterflies.

you will get absolutely no gain if you make them stay open all the time. The only thing that will change is a reduction in fuel economy and low end power.

If you want to gain anything, take them out. If you want, you could also remove the valves and shaft from the assembly, and keep the assembly in there.

 

Can anyone give more info on this?

all i did was remove the valves from shaft. It may be causing some turbulence in teh airflow with the shaft in, but its better than them being closed all the time

 

you can get a spacer to put in there instead from blacktrax.net . I dont have any experience with them myself, but you definately lose bottom end with the hose unplugged as Greyout said.

 

Removing the valves and leaving the spacer in there, and unplugging the hose have the same effect. You will get turbulence by leaving the valves and shaft in, but its not a dramatic difference. I have the shaft out now, and just welded the hole it left shut.

 

i had mine tied with a zip tie for awhile, never had n e problems with that, but the vaccum way prolly looks better-

 

I think I will set them to open with vtec. Sound like the best idea?

 

honestly thats a bit too high, its gonna kill you from 4-5k.....i would honestly just leave them open all the time....

you could also get an rpm activated switch from MSD and set them at whatever rpm you want, if you thought that vtec was too high.
