Did a quick dyno pull yesterday, check it out (2 vids and graph inside)

[Fastphil]

I did a quick dyno pull yesterday at a local car show with my 03 Cobra. It was just to find out the peak numbers, there wasn't any datalogging or anything going on. It put down 445.6hp at 5760 RPM, and 483.3 lb-ft of torque at 3263 RPM. I was satisfied and have no reason to worry about anything. I'm posting this here simply to share the experience and the results, but if you notice anything in the videos or graph that might be worth mentioning, please let me know.

One thing is in the video shot from the rear (run 1, green), you can see a couple shots of black smoke out the tailpipes just before the end of the run. A little fine-tuning is needed, perhaps?

Another thing I noticed in the video that was shot from the front (run 2, blue), you can hear the blower whine taper off before the pull ends. I'm assuming this is belt slippage?

Here are the vids:

I've never seen a dyno where they take the wheels off lol. From what I can see you are an upper only car. What are you exact mods?

It's a Dynapack dyno, at least it removes the possibility of wheelspin. First time I've ever used one, but it works.

It is indeed an upper-only car. Mods are: 2.76 BF upper with 100mm idler, JLT CF CAI, stock TB and plenum ported by Stiegemeier, LFP H/E and Supertank, Bassani catted X-pipe, Steeda catback. Unless I'm forgetting something minor, I think that's it.

There's plenty of other threads on the internet where you can voice your opinion on my suspension setup, and I'm sure you'll fit right in in those threads. I'm here regarding my tune.
