Just a quick question:

I think I am finally getting around to finishing my car. The speedpro has been in a box for over 2 years. Question is, I have the remote mount IACV. Do I mount it in the intake pipe? Don't bother installing it? Sell it, buy some CRispie Cream donuts? Get another version? Oh yeah, any other tidbits that I may need to know when I install this thing will help too.

Setup: 2000 civic, bank-bank speedpro, 60-1 T4, aeromotive pump, etc 72lb injectors.

Thanks alot for the help.

You don't need the IACV, it'll idle just fine w/o it.

I dont have the iac on my car and it idles ok but sometimes if i am at higher revs and step on the clutch it will not catch and it stalls. I am runnign 4- 1600cc injectors and was told the bigger injectors dont help the issue either.

what about with a stock ECU? Obvisouly Ill get a CEL, but will it idle at all? I made my own I.M., and Id like to omit the IACV. Im using a p28 because my Eprom on my AEM EMS is fucked, and Im not waiting for that to return to break-in my car...
I hadnt planned on incorporating the IACV into my manifold, and would like to omit it if possible...
A pic so you get an idea:

Hey Tinker. Looking at that IM. Whats the thought behind long runners and no plenum? Just wondering and I would like to pick your brain on the ideas you may have on this. Looks good, but IMO I dont think it'll perform that well. It pretty much goes against all logic on basic intake manifold design.

Sorry for being off topic. I pretty much hate the IAC motor myself. Might wanna dig up a thread by Ben Strader where he doesnt use them in his tuning either. If I remember correctly he just plays with timing along with fuel and a couple of other tuning parameters.

93lscivic, there are two ways to make an IM for a turbo car.. A header type like tunker's or a big plenum short runner IM.. either one will work very well with boost. There will be a nice torque curve with the header style and the top end will be nice, The short runner style usually makes big top end.

BTW nice looking set up tinks

I'm running a speedpro b2b system without an iacv, idles just fine.

Tinker, you got any more photos of that IM?

from my understanding, isnt it necessary to run a slide valve OR a ball valve throttle body when using an intake manifold such as this?

I have some experience on a CBR600f3 motor using a manifold like this...

lovefab, im dying to know more about taht intake manifold. i was thinking about that design, but wasnt sure if it was effective or not.

i hate iacv's

My IAC hasn't worked the past few months, I am going to fix it though... Cold starts suck without it.

Looks damn good too Thanx for the parts Stan.

My theory behind this design is boost-oriented ONLY. To be truthful, Im just trying things out, because I fucked up my stock I.M., and dont feel like buying one
Now to me, if air is being PUSHED into the engine, why not make it as direct as possible? These runners are very direct, and I think I have achieved my goal there. But what Im worried about are pressure waves and such. If I get REALLY LUCKY in this design, they wont collide way up in the collector, and impede airflow to the point where it wont rev anymore. Geoff said some kid locally around him built one(different design), and it didnt rev past 4k. So, will it work? Yes.
How well? I wont know till tonight or tomorrow, and until I get some dyno time in comparison with a stock manifold.
Here are some more pics for those who asked:

I thought about that once,
keep me up trough IM please, I want to know the result of a similar setup cause i'm interested in buiding one myself !
thx

i've used the gm iacv on a sp system before and it worked very well. it's worth while for anyone who's running ac and/or a big stereo system.

the type i worked with mounted to a port on the intake manifold. it was gm plunger style that screwed into an adapter with a built in kn filter element. the only problem that i ran into was that during shifts, the iacv would breifly open and remain open for a short period when the throttle was again applied, which caused some of the boost to escape via the iacv. this was solved by placing a one way valve before the iacv adapter.

i've done systems with and without the motor. while going without it definately works, going with it only further increases driveability.

You really dont need an IACV to idle.

some pics of the intake manifold i was referring to... it is on a cbr600F3 and thge collector was a merge collector CNC'd from 6061 Billet

I personally dont have an IAC and mine steadily idles.

In my opinion, you would only need an IAC if you're running a/c because the rpm fluctuates when the compressor turns on and off. I kept my a/c with no IAC and just set my idle a little higher than normal so when the compressor turns on, the rpm doesnt surge down below 500 rpm and make the car die.

Nice...how did it function? That was the Exhaust manifold you showed me wasnt it geoff?

badCRX

Did you guys have to make a block off plate for the IACV when you removed it. Also, I have a friend with a turbo H22A and Venom manifold and the smart guys there didn't leave a place for the IAT. Do you guys have any recommendation about alternate places we can put it? The motor is assembled and it would be a bitch to pull the manifold off just to drill and tap a place for that IAT sensor.

some more pics of the old small formula car collector IM thing.

Thanks everyone for the IACV answers. I will just sell this thing.

FFgeoff,

What FSAE school was that IM for? Were you guys in detroit in May? Here was my senior project for our FSAE car. CF intake mani for the ladies.
