i want to know what i will need to run itbs on a dd car
do i need a vacum block for the map
i have hondata s300
i have s2 tuner 2 cams
i was going to get it tuned
wat i was planing on doing as driling a hole on each runer and runing them to a custom vacum block and having the map pluged up to it along with the brake booster

 

why?

 

What are your plans for an air filtration, run individual filters or an air box style with a filter?

Have you talked to your tuner to see what they would suggest?

 

it would be cool and no one around hear does things like this

 

Like Ghost said, if you plan on running an ITB setup as a daily then you have to look into some type of filtration. Uni filter makes some stellar products in various sizes if you want just filters on top of the velocity stacks. Or run a custom air box

 

i have a set of pod filters for it

 

What throttle bodies are you using?

 

I don't have any experience with itb setups on Hondas, but I always wonder... why the vacuum manis? Do you guys not tune by alpha-N? The baro sensor in the ecu can handle altitude/baro compensation.

 

The vacuum manifolds are used for other vacuum systems as well, fuel pressure regulator and brake booster just to name 2.

Hooking up the MAP to a vacuum manifold is there to help tune for idle and partial throttle. I usually tune with a cross between speed density and alpha-n. Most software these days allows for a smooth transition between the two.

 

problem with running the map sensor off vacuum blocks is the size and actual vacuum the map sensor sees is incredibly low. your "average" vacuum block you see online will not have the volume necessary to allow you to tune off the map sensor.

you have to run a nice sized tank to get accurate readings. Its easiest to just tune off the throttle position sensor.

i will say this though, depending on the throttles you run, how they are designed and how large they are, ITB's can be annoying to drive on the street. Not only that, but unless you are getting a set that will actually benefit you (ie: racing), a proper plenum/manifold will work great.

 

i am going to make a large vacuum block out of a 3in coldair intake it would be about 8 in long

 

i got a set of obx 47mm itb in a trade for some b17a cams i had no use for
i just like itbs i have a set on my ls1

 

The little black box from an H22/F22/B18 IAB setup works great as well!

 

any updates on this?

 

Makes sense. I've only worked with itb's when there was constant fuel pressure and manual brakes, so that didn't even cross my mind.

 

I've been working on a set for my 2.0L Ford Zetec using MAF and a closed air intake system with no vacuum manifold. I only had them on for a trial run and they seemed to work OK. No MAP on this setup ether. Only the stock MAF and stock ECU.

This is a set that I had originally made up for my F22, however I have since moved up to a set of 54mm throttles on that build.


A work in progress!
