fab up a switch that will keep your wastegate open all the time, and close when the switch is moved

I think they're called Hobbes switches. Don't quote me on that though...

hobbes switch sounds right... a switch connected to the intake that will open with a change in pressure...

yeah, they can be bought.. no need to make one.. they are called hobbs switches...

I have seen people using them for things like shutting off nitrous at at certain boost pressure.. they can be pretty handy...

check here -> http://content.honeywell.com/s...3.asp

or they are for sale here -> http://www.turboimports.com/tu....html

Hobbes switches are correct. these are a cooler looking and cheaper alternative! I have one that i picked up for 25$ a while ago, have yet to use it but it looks like it will do the trick quite nicely and it's adjustable and just installs inline w/ any vaccum source. can either power on or power off something, would work for nitrous till you get to 10psi or something like that.


this guy has like 10 for sale at all times so there are enough for everyone.

NAPA has Hobb's switches, I think they were like 26 bucks, but I can't be positive. Try searching Google for the part number.

I've used a NAPA one in the DSM, and it worked great.
