Hehe, Orote Point air strip... I've actually done a few speed runs in my friend's Skyline out there.
Okay, so I think I've decided on a setup that I would like to try. For pre-compressor injection, I'll probably do a 50/50 mix of water and isopropyl, with a goal of maybe 1.5-2% airflow I guess? I won't turn it on til I'm >13 psi of boost. The second stage be some kind of methanol injection (either pre-TB or direct, I'm not sure), and hopefully I could throw in a bit of nitro too. I'm willing to experiment with my car, but I'm going to have to start out slow.
My last question is regarding methanol injection pre-turbo. Is corrosion a real concern in this instance? Because I'd rather use meth than isopropyl, but not if I'm going to have to worry about corrosion. If I could use it though, then I would probably think about spraying a larger amount pre-turbo, with lower water mixture (say, 60/40 or 70/30) so that I won't saturate the air.
