Hello guys,

When i see pics of some of your cars i notice that most of you don't have an airbox, doesn't give this problems with **** that is going into the itb's?

greets dennis

 

Not really, if you're having things that big fly into your engine bay, then you have some bigger problems!

 

They do make filters if your worried.

 

Can anyone PM me what to possibly search for to find good Honda B16 ITB info? Searching for ITB here on HT doesn't do much good considering most people are like me posting looking for info, heh...

 

ITB's are over rated...i saw 2 fully built motors both running on ITB's with high compression pistons, race gas, hondata, cams, head work, valvetrain...etc.,
the damn things would stay open at high RPM's plus bolts would come loose during dyno sessions...not worth it. hell, my motor put down more power than those 2 through a JG intake manifold

the motor i saw last night put down 185-195 whp on ITB's HAHAHAHA!!! weak sauce

 

Well, i got a real great pm from highendmike.

I know there are filters i can buy or even air boxes, but i was wondering if it was really bad driving without one.

And a good built engine with itb's is more powerful than with a normal intake manifold. Look for example at the car of Tbone.

so im guessing you haved owned ITB's then since that is a pretty bold statement and could only come from someone with experience.......

 

and ITB's aren't only about the power. throttle response and control is improved which pays off

i've driven Jerry Built's original ITB setup and it was not something i'd consider 'daily driven' even though he drove it around everyday
it even had a twin disk clutch setup and runs on race gas...but from what i've seen (about 5-10 customer dyno sessions), those things are a b*tch to tune. most of the power is up top even though there's more torque down below. i wish i got a chance to drive/ride inside Blizzard's setup...i heard it was sick

the way i look at it is this:

more whp up top (around 7,500 rpms or so) + idle stuff + tuning issues + butterflies sticking + cost of fuel + drivability + ITB bolt(s) coming loose vs. JG intake manifold with 70mm throttle body straight through

u guys figure it out

Itbs dont make more power at the top end
Itbs increase mid range power
And if thier overrated you should probably call the guys over at Renault and tell them about your intake maninfold

 

bolts coming loose is an install problem. And the amount of power you make and where you make it depends on more things that just saying you have ITB's. There's runner length, throttle size, type of velocity stack, runner diameter, etc.....

and also, you are talking about a full out drag car, of course driving that on the street is going to be a bitch.

heh...if honda made ITB's stock on the B-series motors from factory, then it would be a whole different story yea? besides, that renault you posted came from the factory stock most likely

they don't drive full drag cars out there in FL?? HAHAHA!!!

There are cars that are comparable to the Bseries stock that came with ITBs. Forget the "supercars" like the GT-R etc.

Toyota had the AE101 and AE111 and even technology from yesteryear had ITBs on the original E30 M3.

All of which incorporated airboxes, "mild compression" for reliably daily driving.

To the OP: The short answer is you should be using filters on your ITBs if you intend to use them on the street.

i must agree with you on this one but since then, the California Air Resource Board (aka CARB) made sure to put a stop to these cars which was like
and that's why you'll never see a LEGIT carbed ITB B-series motor swap out on socal streets...unless it was done illegally

 

thats why i and many others dont live in Cali

 

At first he started downing itb's on the pretense of power, driveability, etc. After he was schooled a little more on the subject he started downing them because of carb compliances, and legal issues, so what i want to know is what else he will make up to down individual throttle bodies.

You're comparing a Renault F1 engine vs. A b-series on itb's... give me a break.

 

i thought one off the advantages if ITB's over plenum intakes was that when using a plenum intake you can never guarantee each cylinder is getting the same volume of mixture as you have four runners sucking from one plenum whereas ITB's can be tuned individually and therefore each cylinder can be tuned as as separate engine almost, i.e. if cyl1 is running hotter than cyl2,3+4 then cyl could have its pulse width increased to try and cool the piston crown, just an example but you know wot i mean

 

Thanks guys for your opinions.
I bought an complete itb airbox this weekend, and my cold air i am getting from the front of the car.
I am going to make an picture of my complete set, i will post it when it's on my comp.

Greetz dennis

 

What air box is it and where did you get it? What car are you running the itb's in also?

 

It's an airbox from Lumention and its the Super Competition airbox, i got it from a engineering Rally/Race shop here in the netherlands. They have parts for the rally cross, dragrace and other sorts of motorsport.

The itb's are going on my Build and fully balanced B16.

I will post my itb's when i made a pic, i think tomorrow.

greetzzz

they seriously just plain suck dude get a grip and smell the bacon...people put them on for obvious power gains and what not but in socal streets for a daily driver with race gas...that's just too gangster...then again, I'm not Jerry Built Racing
