Yup, went down to the track today for a few 1/4 mile passes. Wound up with an 11.75 @ 120.81 mph. I'm too lazy to go get the slip from my car, but the 60' was something like a 1.83 and the 1/8th was a 7.60ish at 93ish. I'll update this with a scanned slip later on.
Now, does anyone remember this thread: http://www.stangnet.com/mustang-forums/threads/nitrous-and-a-roots-supercharger.832133/ ?
Well, I can answer that question. A roots blower LOVES the nitrous. I put a dry kit on my car a couple months back and have been testing/tuning it for a while. Finally got it dialed in about like I want it. I hit it with a .029 jet (about a 25 horsepower shot), and it went from a 12.15 at 116 mph to the time above. So it picked up .4 seconds and 5 mph on a tiny shot. It definitely loves it.
I was honestly a little scared of hitting it too soon on the track for traction reasons, but it was hooking fine today. That best pass came with me leaving at 1700 rpm and the nitrous coming in at 2400 rpm. However, later in the day, I bumped it down to 2200 and left harder at 1750 and got a 60' down to a 1.77, but this was on a hot-lap and the time wound up being a tad slower overall (11.80 @ 118). I think that having the nitrous come in at 2000 rpm and with a good cool down, it would go 11.5s at 121ish. Oh well, maybe next time.
