Well I think the raspiness I was worried about is mainly only audible from inside the car. I finally got to hear it from the outside when I got it Dyno'd today, and it sounds great from outside. The place I was planning to go (that had a Dyno Dynamics) had some scheduling issues, but I might go back there Monday. So for now, I went to Carboys here in Houston where they had a DynoJet available. They did 3 runs, they looked pretty consistent. Max HP was 305.3, Max Torque was 241.2. These numbers sound a little low to me for full intake/exhaust compared to what else we've been seeing (given that its a DynoJet), but on the other hand (a) This is a 7AT, the rest have all been 6MT so far, (b) It was extremely humid in Houston today, and (c) Every dyno and every car is different

Anyways, I realized after I got home that I've got no way to make the graphs. He gave me the raw DGP file for the runs that has all the data (including A:F ratio), and you're supposed to download some free software from DynoJet to view it and make your custom graphs. However, I'm all Mac here, and their software is Windows-only. Anyone else wanna take my file and make graphs for me? Video is uploading to youtube now too, I'll make a separate thread for the vid and the graphs (if someone can make them).

They also gave me a printout of the best run, I guess I could find somewhere to scan that in. The printout has lots of "gaps" in it, I'm not sure if it's just this run or if they're all like that. The tech said it was his sensors or whatever that were at fault for the gaps in the lines. Anyways, for a text analysis of what I can see on that, the torque curve is pretty broad and flat from about 4.5k to 6.5k, the horsepower is basically on a 45 degree slope that hits peak a little under 7k and stays there to where he cut off at (7.5k). Crossover point is about 6.6k.

Edit: bleh that DGP file he gave is like 95 bytes long, clearly I don't have the data, gonna go back by there later and get the real thing.
