does this setup still use v-stacks? looks nice

 

Yes, they are built into the bottom of the plenum.

 

Quick question concerning a water-methanol injection system--seeing as how methanol is highly corrosive, do you have to worry about your vavles getting corroded?

 

No.

 

Ok, because of....?

And, if the goal is to cool the charge (and decrease the chances of detonation), wouldn't a 50 shot or race gas be easier?

 

waiting to see how they perform

 

First off, methanol is not highly corrosive. It is slightly corrosive to aluminum, but since it isdiluted with water and the amount injected is so small corrosion is not an issue. Especially with the valves as they are stainless steel. But I think you miss the whole point of water or water/ meth injection and I suggest you visit this forum and read up on the topic.

I wasn't way-off basis here. Based on what I've read thus far, a WI helps decrease the chances of detonation/supresses knock (thereby allowing you to run more boost), lowers EGTs, and can increase torque.

 

simply gorgeous

 

amazing!
