Im trying to find out where the IAB solenoid is located at so that I can wire it directly to a26.. it sucks when I try and hit vtec.. it feels so slow.. I guess because the dual butterflies are not opening up..

 

HELP!! I need somebody.. HELP! not just anybody.. HELP! you know I need someone... HELLLLPP!!!!

 

 

Wait.. isnt that the IACV sensor???

 

absolutely not...
This is an iacv:

It attaches to the back of the manifold, not underneath like the iab cannister

oh really?? so its under the manifold and not behind it right?? well my car cracks pretty good already in vtec.. imagine after I install the wires for the secondary butterflies.. it will start soaring

You really dont usually notice GSR VTEC. It's at 4400 RPM. The butterflies open at 5700 RPM (with a GSR ECU, ofcourse). Usually, you notice the butterflies opening...but not VTEC. VTEC is pretty silent on the intake side. If you have an exhaust, you can hear a subtle change.

It's silent, but deadly. Like a beer fart .

Hmm, well I can notice a dramatic difference in sound and power right around 5k...(gsr with i/h/e)..So is this difference in sound and power actually the butterflies opening up and not VTEC like I always thought it was?

Well...if it's around 5k, it's most likely VTEC.

However, with my GSR, the only sound or power increase I noticed was at 5700 when the butterflies opened.

Well I have a bone stock JDM gsr obd2 in my ek.. no cat either but test pipe.. right when you hit vtec it CRACKS.. you notice it big time.. I guess because theres no cat and its basically straight pipe.. I also have an es oval exhaust 2.25.. so after I install the wires for the secondary butterflies to open up will it increase power and sound even more loud???? I hope so.. its great right now and loud even without installing the IAB wires yet..

 

A buddy of mine removed the butterflys on the mani completely. Is this better?

He thought he would get more horsepowerz didn't he?

Why would Honda even spend time and money on R&D if it is better to not have them?

 

Best solution? Remove butterflies or get an aftermarket manifold. Get a B16 or ITR trans.

The butterflies are there because of the GSR's horrible gearing. Honda wanted to showcase their butterfly technology. Which sucked. Think about it. If it worked so damn well, why not use it on EVERYTHING? I understand that the GSR was supposed to have a different dynamic (torque down low for plusher driving), but that could have been solved with less crappy gearing. If the GSR had the ITR's trans, there would be no need for the butterflies.

The butterflies dont really help THAT MUCH anyway. Here's a hint. How many Hondas come with butterflies now?

That was kind of a cheater question. lol...Most cars (Honda or not) come with variable cam timing now. So no need for butterflies in any case. But still....the butterfly idea on the GSR wasn't so great.

I'm sure people will disagree.

 

so what is so good ABOUT HAVING A GSR then

Actually, it worked/works quite well. It was a forerunner of the variable-length/variable geometry intake setups found on many modern high performance engines. The concept itself is a good one, and Honda was able to create an elegantly simple design. Removing the butterflies on a relatively stock engine makes no sense. It certainly won't generate any more power down low, and it will be equal in power up top, since the secondaries would be open anyway.

Variable valve timing and variable intake length are two totally different things. One is not a "substitute" for the other, and both can work together to improve a power curve.

 

will a b16 manifold fit on a gsr head ????

PR4/P75/LS/CRV only fits its own head - LS = LS
P72/GSR only fits its own head - GSR = GSR
P30/PR3/P73/B16/ITR fits its own head - B16 = ITR
