Consolidation of mods, dynos, and track times

ok I went to the track again and got lined up with a f-250 powerstroke and thought to my self "I am going to get spanked" well I was wrong he got me off the line but about a quarter way down the track I pulled on him and it was a bad run at 16.1.

the second race I was lined up with a friend in his mazda3 2.3 I just spanked him and I ran a 15.7 im a little happier with that but I want lower. so I will let you all know how it goes next time. also if you want pics of the time slips let me know.

OK I went back to the dyno but I have some odd results. HP went up on the motor, but down in torque. My nitrous numbers also dropped dramaticallly to where I thought they should have been all along. Not sure why this discrepancy happened but here's some numbers for you all to consume. I believe the numbers on the motor run and the nitrous runs for this trip. This is the same dyno I used last time. It is automatically corrected by the software.

Looks like some of the numbers got cut off..
Here are the "raw" scans.

Saw this and thought it might be nice for here: Timeslip Database. Since ekool owns that one too, should be easy to integrate.

Very nice....thanks!

I just did a baseline dyno to see what the truck was doing stock before we start adding mods. Here are the sheets.

It was raining and the truck had about 350 miles on it and had just been driven 60 miles to get to the dyno...

Here are the numbers since I can't seem to get the photos large enough to read....

11:28 am // 83.32 F// 29.89 in-Hg// humidity 78%// STD 1.04// 237.04 HP// 243.83 Torque

11:32 am // 84.17 F// 29.88 in-Hg// humidity 77% // STD 1.04// 240.84 HP// 296.99 Torque

11.36 am (airbox open) 90.21 F// 29.89 in-Hg// Humidity 72%// STD 1.05// 250.71 HP// 304.71 Torque

11:41 am (airbox open) 88.19 F// 29.89 in-Hg// Humidity 69%// STD 1.04// 249.04 HP// 310.73 Torque

Hope this helps...

These are the Air Fuel Ratio sheets from my baseline dyno run...

I ran a 15.4 and a 15.5 on the 17th.

CaptFDU, do you have a bigger pic of you A/F ratio with dyno chart. It seems you are running pig rich and I'll bet you are loosing a lot of power due to it. Ideally you want to have ~12.8-13.0 A/F ratio to maximize hp. I have never seen one run as rich as yours. Do you have any exhaust mods?

[RockyMtnTitan]

Wow...you got some good eyes, Z. I can barely make it out, but it looks to me like his afr was at about 10:1, or even lower. During my runs, I was at an almost perfect 13:1 throughout.

I will try to attach a larger pic. The guy that was doing the dyno said same thing about running very rich. I'm not sure how that can be fixed just yet, but he was going to do some research for me. This was a baseline dyno run 3 days after i bought the truck. No mods at all so we could see how much improvement we are actually getting. Any ideas on how the lean the truck out???

Me too. My AFR was dead on. A little richer around max toque and leaned up at max hp. I dont see how it could be improved upon.

However, CaptFDU's looks way rich (way richer than any other Titan I have seen on here). I dont think there is anything you can do without re-programming the fuel curves, but a reprogrammer doesnt exist yet (as far a I know).
