NPP Exhaust Valve Controls

[XfireZ51]

Chuck,

The motor starts w vacuum ON for the actuators. Flipping the switch un-grounds the solenoid and vents the vacuum exposing the actuators to atmosphere and therefore open. Not sure I understand your question. The fob is not involved here.

I installed the power effects complete cat back system on my 1990 ZR-1 back
in Aug 1997. At that time the company ( Lawrence- Kaech inc. ) offered a
electric motor to open and close each power capsules. I ordered some gaskets
for my system ( I'am always taken exhaust off to work on the auto install )
last year in July. You could try and call him to see what type of motor they
used. below is the contact information.

Got it there Dom; either rig a spring-loaded arm for the 'return' position, or a second vacuum line for 'return' position...

...or a mechanical linkage........................................... ............

John,

Thanks but that's not necessary. Now with the installation of the ground interrupt switch, actuators work fine. You can see the video of the valves in operation in an earlier post of this thread.

I think aafc was directing his post @ me there Dom, since I have PE pipes (and by coincidence, an automatic)...

Thanks there aafc; got it!

Oops.

hi folks, I have a set of the C6 Z06 tips and am interested in a "controllable" setup that allows the system to do the following

1. open on low vacuum (under load) but ONLY after 3000 RPM (RPM activated switch)

2. full time open

3. full time closed

I don't have secondaries anymore so the factory vacuum pump up front could be used.

don't want to spend a ton on this either.

any ideas???

I'd settle for just #1 as that's the biggest requirement. thinking an RPM activated vacuum switch or valve might do the trick combined with a small vacuum reservoir.

hell I might just do this with some old servos from my RC planes and just do it all electric. I'd need a circuit to step down the voltage or just better yet find some 12 volt electric actuators (like the quick time idea)

lots of options, but so far nothing that does what I really want.

might try this on the Turbo Z06 first before cutting up the B&B which is all polished up and looking purdy right now. I love the bark of the LT5 but it's a bit loud for trips.

Ron,

mike100 has the setup ur looking for. He has a write up on it. Mine is manual using a toggle switch which is satisfactory for me. The secondary circuit can provide switched power for the vacuum solenoid. I use vacuum from the charcoal canister supply.
The rpm signal can come from the DIAG connector near the firewall.

Coming Soon!

As a matter of fact, Mike 100s article is due to appear in the up coming issue of HOTB, scheduled to be released in April. It is very comprehensive and has both vacuum and rpm considerations to prevent opening under normal highway loads such as hills, etc.

It's cheap, especially if you are willing to scrounge for some of the parts used. The mufflers and the welding labor are the big cost. I'd say $100-$150 dollars more for a complete system. I personally used the more expensive German style braided vacuum line, but you could save a ton there. I already had clamps and tie-wraps, but you could maybe add $10 for misc hardware..parts store plastic vacuum T's, etc.

The two must order items only come out to $75 or so.
