Is there a sensor that I can unplug, or do I need to force the falve to stay open with a zip tie or something?

 

Keeping the secondary open will make you loose a lot of torque on the lower rpm band.

 

I know that. I still want to know how to do it.

 

Just get a Skunk2 Intake Manifold and never have this "problem" again!

 

 

i would just wait till 5700 then u shouldnt have to worry about keeping them open. if u can shift correctly u can keep them open all the way up to your top speed.
want proof? ok just driving a 2001 gsr with an air intake shifted at 8000 landed at 6200 theres my way of keeping the secondaries open. or u can do what i did on my own car just get a type-R manifold

 

You can land on 6200?? I never really looked where it landed cause i was always too scared to not look at the road. Whats with this, people say you can't land on vtec in between shifts and that you need an ITR tranny. Are people just stupid or am i missing something?

 

I don't know how you do it, land at 6200 rpm from 1st to 2nd. I land at 5500, but then again, I must be a bad driver.

 

Oh yeah, to keep secondaries open, you can take out the butterfly valves when you remove the intake manifold. Or you can disconnect the vaccuum line from the golden dashpot on the driver's side of the intake manifold. Plug up the vaccuum line. The best way if you plan to keep it that way is to just remove the butterflies.

 

Is there an advantage to having the secondaries open up at 4400 rpm or when VTEC crosses over instead of 5700RPM

Who ever falls out of vtec with a stock ecu shifting at 8k is just a plain old shitty driver. Anyone that shifts at 8k should never drop lower than 5k. When i shift at redline i will drop at 5600-5700. Now since my clutch is starting to slip i land higher like 5800-5900, even tho it lands higher it isnt better cuz the clutch is wasting time to engage. I just put my skunk2 intake manifold on this weekend and the top end power is just their now. It flows alot better than gsr manifold from 6k up. Im waiting for my single runner skunk2 ecu now and it will feel so much better, cuz the fuel and timing maps are different for single runner, as opposed to dual like a stock gsr manifold. peace

 

lets give a little lesson in racing and the roles of torque and horsepower. high torque will get you going fast and horsepower keeps you going fast. why would you want to decrease the amount of bottom end torque on your car? the end result isnt going to give you enough upper hp to catch up.

 

I wonder how many people have removed their butterflies on their daily drivers. Idiots.

 

I haveand im happy

 

question: why would anyone want to remove the secondarys or rather keep them open all the time?

you lose mass trq down low, why dont you disengage vtec crossover at 4.4+ while your at it too?

am i missing anything here?

 

just unhook the punamatic line going to the actuator. at rest, they are open.

 

un hooking the secondaries on GSR manifold is absolutely worthless. Unless you have a VAFC and can correct the fuel settings, then you will lose power in the low and some midrange.

 

well when I took my car to a track day at Pocono, the secondaries were open pretty much all of the 125+ miles on the track... that is my favorite way to keep them open, yeah all day above 5500 rpm was bliss. In fact that is the only way I know and only way I recommend to KEEP them open.

 

Heck, i can still land in the high cam shifting at 7.5K

shifting at redline secondaries stay open.

 

Matthewk - would you please explain WHY you want to keep your secondaries open at all times? seems pointless unless you're running big cams an/or high compression pistons to make up for the torque loss - this topic has been covered many times (mmm...search) and can be beneficial for the reasons above, but if you don't have at least 1 of those reasons DON'T bother - Honda knew what they were doing w/the GSR and its dual stage intake manifold - IMO don't F with it

 

Well i went driving last night, 1st-2nd i land at like 5.6k, then 2-3 i land above 6k. Am i a shitty driver or is the GSR gearing made to do that?

 

As everyone above is saying, there is NO reason whatsoever to having them open all the time..

Fk taking them out like some people talk about.. Only guys that keep the GSR manifold for racing class reasons would actually take out the butterflies.. To keep them open ALL THE TIME, just disconnect the IAB solenoid.. It's a 2-wire circular connector on the drivers side under the manifold runners.. But again, there's NO reason to do that for ANY reason, imo.. ****, I spent a week figuring out how to get mine to work.. lol

 

And to clarify, the secondaries open any time AFTER 5700 rpms when there is low vacuum to the diaphragm (~75%+ throttle).. It's the same 'technology' that's been used for many years on vacuum-secondary carburetors.. (go figure)

 

it seems like there would be an aftermarket company that would sell a device that opens them just a tad sooner but not to early. I think I am gonna start my company now! if that actuator is removeable then I believe this would be a practical mod if it is easy to replace with one that opens at like 5? but any sooner would cause tq losses

 

It probably wouldn't be too difficult to control them. I would start by using some vaccum controlling solenoid valves found in honda vaccum control boxes. Wire up a circuit to make it work and you might be on to something.
