Has anyone who has supercharged their 4th gen also added a meth injection system? If so, could anyone show me the setup they used, or at least explain it?
Meth is super corrosive. U need about 45-55% bigger injectors to run meth and make sure you replace that rubber with viton. On the car we ran it in egts were about 250 degrees cooler so that's a plus and you can run good amounts of timing on that fuel.
You don't need anything special for it all you need it the fitting for your I take tube we always you the windshield wash fluid to pump it in. The only down side is you loss the use of the wipe was fluid
Snow performance makes excellent W/M kits. I have been using their Stage 3 kit on my Audi with a big turbo kit. I have a colleague running a similar kit on his Audi v8 with aftermarket super charger.
I think the w/m kit is an add in for you after you get the motor super charged.
