Talked to my mechs about nitrous.

I've been doing a bunch of research on nitrous for the Yaris and read a few differing views on here. So I finally went and talked to my mechs down the way yesterday. They have been working with the stuff for years and I figured they would be good for some advice.

A few people here have warned against dry shots due to the temperature and the plasstic intake manifolds. Apparently the cold shatters or at least cracks the plastic. So wet was recommended.

Mech's response... If the dry will crack it, so will the wet shot. Doesn't matter where you inject it, when it gets to the IM it is the same temp. In fact the cold is part of why it works.

So they recommended the only safe way to add nitrous is to have a metal IM. In other words, get a supercharger and a 50 shot is fair game. Leave the IM OEM and a 25, if you can even find a wet shot kit that low, could seriously damage your little econobox. :p

Just a fyi since there seems to be no OFFICIAL advice here. Not saying this is the end-all. But I have known these guys for a long time and they know what they are doing. Were working on a 754rhp 05 mustang while I was there.

Anyway, like I said this is not gospel. So techies feel free to criticize or confirm this. I think I can speak for all of us here when saying your opinions are more than helpful. :)
