So, Tyler and I did some testing on the dyno this past weekend. We were testing various fluids and nozzle sizes in a pre-compressor injection situation. It was fun and we learn alot too. Anyway, just figured I'd share a few videos that I took with my Blackberry. This video is cool as hell. This was the run using straight water with a 7GPH nozzle. It starts spraying right around 51 seconds into the video. www.youtube.com/watch?v=F51xymg33-wAnd here's a video of one of the pulls: YouTube - Engine Dyno Pull @ Street & StripAnf just because we like having pyro fun, this was using the 10 GPH nozzle with straight methanol. www.youtube.com/watch?v=fw_l2OCUtYw

so what kind of temp decreases did you see? Any chance that you guys will be trying this for any extended period of time? I am curious about the water drops that are in the intake pipe and also if deterioration of the compressor wheel will happen.

I am curious about the water drops that are in the intake pipe and also if deterioration of the compressor wheel will happen. We got our best AIT results using windshield washer fluid through a 7GPH nozzle. See this thread for the test results: www.dsmtuners.com/forums/nitrous-alcohol-water-injection/363191-pre-compressor-injection-test-results.htmlI'll be installing this same injection set-up on my 2G. I need something for cooling the air charge between stages. So, after running it this whole summer, we'll see if I have any indications of wear. I don't expect any though. The fluid comes out of the nozzle as a fog. It's very high pressure and very close to the compressor wheel. In fact, methanol atomizes so well, that it completely flashes off inside of the compressor cover before it has a chance to exit. Also, regarding the water droplets in the intake pipe; in that video, we were using alot of water. More than most people would use pre-compressor. Although we did see significant gains by using as much as we did, I probably would not recommend running that much just due to water's poorer atomization and poorer ability to flash off (as shown in the video). The next test will be to determine how much methanol is needed to be able to eliminate the intercooler without a performance loss.

Dang, pretty lucky that turbo didn't make minced meat of your BB! Now THAT would be a sweet video! So all this talk of playing around on the S&S dyno...does this mean you might have some dyno sheets to share of your compound set-up? Please say yes...

Yeah, I would have been pissed if I messed up my BB. lol We had it taped to a jack handle and set it up right in front of the compressor inlet, so it wasn't going anywhere.
No dyno sheets of the compound set-up yet. We were using a 2300 Ford engine on the dyno. Tyler's engine dyno has never been set-up for a 4G engine so it would take some time and work to get one running on there.
I'll be (hopefully) dynoing my car @ Paul's High performance in April. I do have alot of smaill things to do to the car between now and then though, so only time will tell.
