I really appreciate how direct yet un 'scripted' your videos are. It's clear all this knowledge is in your head and your heart 💖 I understand how much time and effort goes into these videos! I'm sure a short video would take well over an hour to produce.
I primarily work with bikes, which come standard with ITB's. The benefits come from the ability to maximize the air charge available to each cylinder. A single throttle will ALWAYS provide different volumes of air to different cylinders. More throttles and more o2/egt sensors = more better. :)
ITB with an airbox can also suffer from imbalance unless you are fortunate enough to have alot of realestate for a large volume box and large diameter inlet.
You guys win the cigar by a mile, its the first time I have watched a video were diameter of the throttle body has even rated a mention, well done. There is a guy on UA-cam call Richard Holdener and offered to pay for him to put a engine on the dyno and test if diameter was important. Hi reply "Everyone know its all about length and diameter has nothing to do with it so its a waste of time testing". I was putting 10 k on the table and that is what I got back, a closed mind.
@@greggreg6975 I have done the testing as I have my own dyno's and pressure transducers to read the pressure waves on intake and exhaust. I think there isn't enough development or understanding of what really happens with exhaust and intake pressure waves on a NA engine. Not everyone wants to fit a turbo. My purpose of making the offer to Richard was to open peoples minds to what pressure waves are all about and how you can use them to develop a lot more power in a NA engine. Simple fact often missed the timing of the wave is determined by the length of the intake but the force or size of the wave is determined by the diameter as has been mentioned in the video by Andre.
@@anthonyparle7342 ok you have lost me. What does the size of the throttle body have to do with the Internal diameter of the intake and exhaust manifold? As long as it flows enough air for it not to be a choke point.
@@greggreg6975 You are correct if you are not trying to tune for pressure waves. If the goal is highest VE possible then you need to reduce diameter to increase the pressure swing. It s far to complex a topic to discuss in comments. Maybe have a look at the post on Speed Talk were I posted a pressure trace. It might help you understand what the concept is.

Tuning the length is not about creating a RAM effect (that is something different). Tuning the length and diameter is more about Helmholtz tuning I think? Albeit lots of good info in that video as usual and I aways learn a few things, so thanks a lot. The other thing you didn't get a chance to touch on is taper angle of the trumpets. Done a bit of playing on a dyno with inlet trumpets playing with lengths and tapers and also just a little bit of work on variable length and dual stage and it is amzing how well theory and real world results actually match up. But still have lots more experiements I want to do.
I've never modified a car, therefore sorry for the dumb question that is coming : If you install an ITB, you delete the air filter right? Then isn't this dangerous for the engine?
This car actually runs filters, they're just off to show what we're talking about. You can run individual filters, a filter box over the top or in some applications a plenum chamber just to name a few options. Some people do run without filters, but it carries all the risks you assume it would. That said, risks can be different between different motorsport applications, such as drag racing vs dirt oval - Taz.

#BALANCE
ITB with an airbox can also suffer from imbalance unless you are fortunate enough to have alot of realestate for a large volume box and large diameter inlet.
You can run a much more aggressive cam profile with ITBs and still have an engine that will idle, I'm surprised this wasn't mentioned in the video.
An unexpected downside of throwing them on AFTER camming the engine.
The sexy idle disappears :(
@@esnevip The solution to that is even wilder cams :)
Torque: I dont feel so good
Very true
@@esnevipNormal throttle bodies and individual throttle bodies are both closed at idle so why would they be any different? Serious question.
Appreciate all the videos and live shows guys! Keep up the auto love
i really love the way how itb looks and the sound.
Q: Why Are ITB's So Popular? A: awesomeness. okay next question.
ok.. Witch sounds better, ITB's or a big turbo at full noise?
@@greggreg6975 easy, ITB cause pure engine noise :V
@@TheMegajr Nice!!
That last part is so helpful, thank you.
you should do a video on tuning itbs.
Always good to learn something new

Interesting, I read a basic introduction to throttle body diameter in the Megasquirt introduction tutorials even.
Would have been easier and cheaper to test it yourself, why go through all the hassle?

Thanks for sharing this is my next mod for my k20a with drop in cams

What ECU stand alone is good for ITbs thank you
Them trumpees tho 🎺 toot

@@hpa101 I see! Thank you very much for the explanation! Really clear!
very helpfull!!
Strat the video with ITB breathing K20 EG ...Now I'm jealous .
Any chance to get a link from footage of that particular civic ?! Thx
How does this relate to BMW valvetronic? as in I'm trying to modify a N52 to run with open trumpets omitting the throttle bodies entirely.
Broda, I have a hyundai tucson 2009 2.0, is this compatible with this engine ?
THANKS!
hola el sensor de temperatura de aire donde va ubicado ?
Any SR updates?
Why do some boosted engines run itbs, like the rb26
I’d like better ear-flow in my chally.
Excellent bitesize video, what do you mean by brake points?
He means "breakpoints" -- the interval between data points.
Because people like to make their lives harder 🤣
Itbs popular? What?
I only heard them once on an ae86.
I want some for my mx5 though
No?
Que groso
