Here's the dyno plot at the wheels on 93 octane no spray, and 93 octane with spray. Boost was 17psi, air temps were 74 degrees.

My numbers should be close to reasonable for that plot. I figure probably some 300 degrees out of the turbos at 17psi, which may be 120-140 after the intercoolers so you are probably well over saturation even with your small nozzles. That's not to say more spray won't help, it just won't get the temps any lower in the manifold, just keep things cooler and lower pressure during compression.

We did not set the system up to be progressive, but rather to spray fully immediately once in boost. I'm sure there's more tweaking that could be done to the system but I didn't want to tune specifically for meth, and then have a meth delivery failure while in boost.
I spoke with Jerry @ Eurocharged and he recommended the smallest nozzle size as, in his words "larger nozzle sizes can mess with adaptation".

The car feels more responsive now in the warmer temps here in Houston... I'm looking forward to seeing what benefit exists once we get into triple digit temps down here.
I did a subsequent draggy run and matched my previous 104 octane run using only 93 octane and water meth, so i'm ecstatic about that, both in ET and trap speed.

Based on the positive results I've seen with this kit, a friend is installing it on his Stage 2 EC tuned E63S today. We are both attending a track event tomorrow so I'm keen to see the results. His quickest to date was an 11.02, so I'm hoping this pushes him over the threshold..

It's not really an issue when running straight water. But what I ran into with larger fixed shots was ignition issues. Distribution was poor with a single nozzle so when overspraying beyond saturstion it would cause misfires and of course the computer would then shut down that bank as a result. So I had to go to one very small nozzle per cylinder.

After cat delete, stage 3 Kleeman ECU tune already done we are having temperature issues on my 2007 S65. The intercoolers' temp raised to 190+ and we were not able to dyno it properly. It only showed 12 psi of boost and we found no leaks. Kleeman says, and I think it make sense, the engine was protecting itself. Never saw more than 458hp, never mire than 150mph.

Will this methanol systems will help with this? Is it the best aproach? We will add an 10gpm aux water pump, but everything is so tigh under the hood I feel a larger radiator for the intercoolers wont do much.

Any help will be greatly apreciated!

How do you got air temp so low??

Can anyone who has installed this kit tell me where they grabbed the 12V yellow ignition wire connection?
Thank You
