Read all the posts, this is an awesome project Smitty, thanks for looking out for "more power" for us.
I really like idea of the automatic opening @ a certain RPM. can't wait to see the finished tested product.

i am sending the DUMP back so the JIG can be made so he can produce them for you guys....
Being it is the HOLIDAYS, I am sure we will see the finished product mid January or so....and I will have final pics, prices and step-by-step instructions.

I've had a lot of similar ideas myself. Some not to practical but interesting none-the-less. I'd like to talk to you about some of these ideas since I will not be doing anything with them - and apparently you're a go-getter!

Just one little question here ,what are you going to do with the secondary O2 sensor? Since the cat will go missing here the O2 sensor will report a fault code for ineffient catalyst .Is there going to be something that will fool the O2 sensor into thinking all is well??

This is the SIM... it tricks the O2 sensor... casper electronics sells it too, but Brad (Modaddict) agreed with me since the ones I got built have red LEDS built into them so you know they are working.. 1 LED flashes ever 3.3 seconds and the other is constant power...this way we know the unit is working properly!!.. I can provide instructions if you wish to TRY and build your own.. but I have a local retired TV repair man that loves to knock these out in about 4 hours time... 30 for parts and 20 for labor.. you CAN'T BEAT THAT with a 10 foot pole!!!!!
Don't worry fellas after this is all done I will have a whole package worked out and a break down of all the parts...
I did not discuss a final cost with Dave Hacker yet... but he will do anything if the task at hand is RESEARCHED 100%, the guy hates when people GUESS measurements!!...
I just got an e-mail from him... Dave states--->...."Hey, take it easy. Your out of control. I wont be doing much for the next few weeks anyway. The wife has laid the law down on me. Stop working for the holidays or else. I dont like her or else's. So get it done when you can NO RUSH "...

I was only going after the heater circuit in the front sensor when I tried because the TE wideband took care of the narrowband o2 signal. My stock front sensor is still connected, wrapped in foil, tied up under the car with the signal wired going to the ecu, connected to the wideband.

You mean like this?.... alll the DUMPs will have a BUNG already set-up so all you have to do is screw in the O2 senosr or take an 18mm bolt and plug it up of you wish not to use it.

Hey, Smitty.
I've PMed you about something like this a long time ago. I'm not sure if you remember or not.
But I guess you got everything going. That's awesome!!
I have been doing some research myself, and I was about to go with the QuickTime product. But I just saw your pictures, and there's no doubt that I am going with this one.
Where do I sign up??

Any updates on the dump pipe as to are you keeping your original plan of being able to open at 25% 50% 75% and 100%, or are you going to make it open automatically at a certain rpm? Are things moving along nicely?

Smitty...whats the update on the group buy for the grilles???Thats all I need to start my entire front end conversion/update. I don't know if I can wait any longer bro
I got everything waiting to install except the center grille. Thanks alot man

I cut my e-mails once a week for updates and no response on ANYTHING....
I will make a phone call as soon as I can break away from work.

this seems like a great mod at a great price. I cant wait to see the dyno numbers and a sound track of this thing opening and closing. I would love to open this thing up next to a rice burner. Excited just thinking about it.
Good work Smitty.

Wouldn't you need a fast valve that could open in around one or two tenths of a second to make vtec switching of the valve practical. In three seconds we will have already shifted gears. I am more than sure you are aware of this. How do you plan to address this?

Jim, we are still putting it thtough R&D for thr switch operations... we are trying to tie it into the CPU so the valve automatically opens when you have the switch flipped to ON....
We are still working on ideas...
I cut the guy 3 e-mails so far and have not heard from him.. his CPU must be down..
I will call tonight and get an update.

Or open automatically as the RPM's rise? If so, will that still allow the user to manually open/close? Like at a stop light if we want to scare some people...

Will you need a high speed valve for it to be open above a specific rpm and closed below? You said the valve you have opens in about 3 seconds.
Another thing I have been thinking about, I read in this thread that if the cat and o2 sensor are in front of the valve you will not need an o2 simm. However, it seems it is not possible to do this. In saying so, you have placed a BUNG on the pipe for the o2 sensor in a position that seems to be after the valve. Why no just can the BUNG and expect to use and o2 simm since when the valve is open the exhaust gasses will not be passing the o2 sensor, especially since you will not have a cat in front of the o2 sensor. i.e. throwing codes. I don’t know exactly what I am talking about but I think you will understand.

If you're not going to use the O2 sensor (which you really shouldn't and get an o2 simulator), you can just plug the hole with a screw.
Did I understand you right?? :o
By the way, do we have TWO O2 sensors down there? I took apart my friend's '97 GS-R a couple of weeks ago, and he had two O2 sensors. One before the cat and the other directly in the cat. What a pain in the ass, I tell ya.

You got it right Pure Adrenaline. I am still curious about the need fro a high speed valve. Also, I think we have an o2 sensor on the bottom of the header before the cat and one after/on it.

The dump pipe is a direct bolt in replacement for the cat, so you will need an O2 simm for the rear sensor. You may be able to just wrap up the O2 sensor with foil, (it gets hot) and tie it up under the car somewhere.

this is the most up-to-date e-mail that I received from the Exhaust guy:

Sorry for not getting back to you. My wife said someone called but didnt write the number down before she erased it. DUHHHH!! Any way, I will make them. Right now I am in the middle of a HUGE order for Summit Racing. As soon as I get it done I will finish yours up and try to fab up 4 or 5 pipes just incase other guys want them too..

Hopefull he gets his ass in gear, I never expected it to take this friggen long, but I am sure he never expected SUMMIT racing to come knocking on his door.
