it is a Vacuum Accesory Killer. it shuts of the accessories (a/c alternator, etc.) when WOT is detected, via the vacuum lines. It will give you a few ponies (around 3-10, I think, not sure).

I can't say how much HP you get from it, but I can definitely tell you it kicks a**. I just installed one this weekend and I love it. Before the VAK, my torquless wonder duratec would get a chirp, maybe two when stomping it from a dead stop. I did a test run yesterday in 80* weather(Florida winters are brutal, aren't they?) and got a nice 1-2 second solid tire screech. The VAK is definitely worth it, and I would recommend to anybody. Also, it's something you can install yourself, unlike the UDP I got from ShoShop.

Also, on gen 3's, it cuts out the alternator, power steering, and a/c(I think).

i understand how it cuts your alternator, but how does it cut your power steering and ac? What you you have to interface it with?

sorry, was not trying to steal it, i already know how to make a device cut the ac and alternator at WOT, but im just conserned with cutting vacume lines....

sol let me rephrase my question....was it time consuming, or a non reversable install?

It is neither time consuming nor irreversible. It's like intalling a head unit. It doesn't take too long, but you need to cut some factory wiring to do it. You do need to tap into a vacuum line for the "trigger" switch, but in most cases, that vacuum line is overdue to be replaced anyway, so it's no loss.

Everything is controlled electronically. The PS load is reduced via the VAPS electronic circuit. As mikehawk said, we can't really spell it out for you, b/c that would be unfair to Paul Nimz, who developed the VAK.

I sell them for $100 delivered.

They can be adapted to any car but will vary with each type of year and motor somewhat.

I have had one on my '97 SHO for close to three years and on my '93 SHO for over two years, neither has had any problems.


I don't want to explain too much of how they work as there already is a SHO supplier that has copied it and is selling it under their name.
