I was looking for this link and finally found it. This is about over riding the secondary butterflies and leaving them open. Got it off the GSR forum.

Interesting...I'll try overriding the secondaries one day just for the hell of it. Or maybe at a track or dyno...see if it really makes a difference.

" I have never lost to a Type R!"

gimme a friggen break.... that guy needs to get out more often...

 

I cant wait to try this. I know Im gonna love it but im a little scared of no lowend its already pretty bad with my light weight flywheel, but oh well if I wanted lowend I would have got a V8.

 

Hard to believe this guy ran a 14.6 with only an exhaust and unhooked
secondaries.

 

I have seen stock gsrs with boltons run 14.3

 

I tell everyone my car is stock too

 

True.

Then again, I was at the track once, and all these kids were going ape-**** over this 95 dx with a d16z6 swap. All it had was an intake and like 10 miles of green wire loom. The guy said it's just a stock motor.

One of the kids in attendance said, "What stock!, look at all that!."

Idiots these days.

 

doesn't do ****...

except losing a ton of midrange

don't waste your time

 

Must be why the Erick's Racing team runs a gutted GSR intake manifold then huh...

 

anyways............

unhooking your 2ndarys: a small loss in trq down low...no gains up top

= WORTHLESS

 

im glad it is worthless casue i got hella lost with all that mumbo

 

I don't think it's fair to compare Erick Aguilar's race motor to our everyday b18s.

 

You have to understand you're comparing one of the world's fastest all motor Civics to a daily street driven vehicle. The factors are way differerent, and so are the setups. So bite my dust, haha.

 

People keep saying it doesnt make power up top... but obviously it does. That is my only point.

HOW can it make more power up top?? Ok, so they are bypassed so they are allways open. They are also opened for high rpms when they aren't bypassed.......

...so what is the difference. NOTHING in the top end. Midrange is lost though. The longer primary runners create more velocity in the intake manifold, resulting in better cylinder filling at midrange rpms.

Bypassing runners.

 

exactly christ, some people never think.

 

i have never had my secondaries hooked up.

cx/b18c/itr tranny/iceman/crap exhaust and tires

14.0@99.6 w/2.25 sixty

secondaries are played!

 

I didn't read the article but a quick easy way to "bypass" the IAB is to shove a BB into the vac line for the IAB. It'll never move.

I tend to agree with everyone else, though, that this doesn't provide any gains whatsoever.

 

My mistake, I mis-spoke. Ericks Racing uses a GUTTED GSR manifold, not a bypassed one. They removed all secondary related fixtures, not just leave the butterflies open. I agree, it is retarded to bypass them. I apologize for my mistake.

-Nick-

 

he PORTED his gsr intake manfiold and did NOT bypass the gsr secondaries.

This gives him all the high end needs while keeping the low end

 

a big

for finding your mistake and correcting it.

What low end? He stages at 7000 RPMs!
