i have a spare prelude i/m laying around. i am going to try and see if i can modify/ remove the butterflies and see if i can make it work. if i can make it work there will be dynos b/a. i will take apart and look at tommorrow at work. keep you posted. by the way i am new and i will be on hondatech a lot now. just got my own computer. i have the jun built h22a1. iam a honda tech, and have been for 4 years now so maybe i will be able to help with a lot of questions. let you know

 

taking out the iab setup will only lose some tq on the bottom end and do nothing for the top end.....already tried it and it sucks.....if it were boosted, then you could remove them and port/polish it to flow a shitload of air...but on a n/a setup, it just hurts your 60ft times

 

I run mine open all the time...so having them out completely might help a little bit...

mine are completely out too, and even removing the spacer doesn't help....until you're moving huge amounts of air, i.e., BOOST, it is only gonna hurt lowend while leaving top end where it is....i've seen dynos that showed losses of 5-7lb/ft tq until 4500rpm

Well I'm fully built with a modified low cam (Crower 3) I think closing them would be worse in my case

 

i'm 99% stock....that should be the difference........

Boosted, with no spacer or butterflies yada yada ported too......... unfortunatly, my motor isn't done yet, but when it is..... i'll let you guys know.... and if I'm feelin ultra sauce i'll swap out the modified one for a stocker so we can see the differences

 

Leaving them open is always under debate and an agreed end can never be reached. Taking them out as in taking the shaft out helps with hp. The shaft blocks air. It's as thick as a pencil. You will loose a little low end though.

 

i have dyno tested with the butterflies open all the time against normal operation. some slight loss in bottom end and i mean slight 2-lb ft tq and did not gain any up top. i completely understand how the iab system works and i did not say i was definatly removing the plate. i am going to look at and see if can can do one of a couple things. possibly modify the short ports and remove the throttles on the short runners all together. then disconnect the vacum line to close off the long runners at all times. i dont know yet though, like i said i am going to do what i think may work. i have a spare manifold and i figured trying this would be fun. and if i **** it up and it doesnt work oh well, no money out of my pocket.

If you want to do something useful, take out the plates and join the long and short runners together. I saw it done on a mostly stock JDM h22a and it gained quite a bit.

 

if it gained quite a bit, why wouldn't more people have don this, and not just do it yourselfers, but engin company,s.

 

i did it and it felt like ****.....didn't get to dyno it, but it felt off somehow....so i dunno, i just put the spacer back in, and now i'm just running it as is without any butterflies, rod or whatever...completely open, but the stock runner length

 

Talked to skunk 2 today. They said probably another 2 months for the H22 manifold

LOL

 

HAHAHA!! they'll never release it.

 

lol thats what they told me when I was 17


Btw- I am now 19

 

i wonder if they actually are gonna ever release it....you know they're either done with it or they're not gonna get done with it....R&D has had plenty of time to perfect it.....i was waiting but after a year, i'm gonna just make my stock one flow the way it should...screw skunk2

 

Skunk2 always gives run arounds! argh. They are torture..

I saw it in Vegas a while back too. That thing has some massive runners!

 

There just trying to drive up the demand for it so when it finnaly
comes out they sell out in a couple of hours just like the D series manifolds

 

can you post up the before and after dynos? just want to check it out in detail, thanks

 

is there an aftermarket intake manifold for the h22 engine?

Could you please elaborate on how to do this? I can't really picture it in my mind...
