Dyno #s Spreadsheet
In case you don't frequent the dyno numbers thread:
I put together a spreadsheet with dyno #s that TMS members have provided.
Not all incompassing, but it is a handy tool for looking at:
1. Various stock dyno #s (including averages)
2. Seeing the dyno changes for a TMS member as they add more mods
3. Seeing how various mods effect the dyno #s.
4. Worksheet labeled "superchargers" has #s and sources for various mustang superchargers.
5. Click on a members' name to go the the source of the info.
Note that you can filter the selections on the top line. For example, on the 1st worksheet, if you just want to see all the 4.6L, manual, stock stangs, on a dynojet, you just select those options.
Spreadsheet is located here: http://forums.bradbarnett.net/showpo...&postcount=165

Thanks, Mark!
I remembered your other thread about power loss so I used this spreadsheet to calculate the average powertrain loss for the automatic GTs, bone stock. To my surprise, it came out to be 15.2%, not the 20% which one would have expected. You were right over there, we should get used to using 11% and 15% when calculating power losses for the manual and the automatic boxes.
PS: and then I saw you've already done that, when I looked at page 3 of the spreadsheet!

I think it's more a factor of the number of horsepower that the drivetrain loses vs a percentage. This is based on the testimony of a dyno operator that dynoed F-150s before and after engine swaps (manual 4.6L F-150 swapped out for a 5.4L engine). Comparing a 4.6L manual (before the engine swap) to a 5.4L installed in that same F-150, both lost about 35rwhp even though the 5.4L had more hp (260 vs 220). If drivetrain loss is a percentage then the percentage should have stayed the same after the engine swap. It didn't. But the overall hp loss did stay the same at ~35hp.

Thank you for posting this data.
I have poured over it for over an hour.
Sorting is for the win.
Some biased conclusions about modifications.
LT Headers 20, Custom tune 20, Canned Tune 12, CAI 10, CMCV 5-10, Water pump 5-10, X or H pipe 5, UDP 5, Exhaust < 2, TB < 1, Spacer < 0
Typical: CAI and Canned Tune = 285-290 HP / 300-305 TQ for $650
Mid-range: UDP, X-pipe, CAI and Canned Tune = 295 / 315 for $1k
Advanced: Custom tune, CAI, CMCV, Water pump, UDP, Offroad X-pipe, Exhaust = 310 HP /320 TQ for $2500
NA limit is 350 HP and 360 TQ, imo.

Mark,
My thanks too for going to the bother of assembling this info! It is interesting and it forced me to gather my dyno data in a meaningful way, rather than just stuffing the sheets in a folder. I've attached mine in your Excel format and would appreciate it if you would add them to your list.
Another thought about drivetrain loss - it also depends on the dyno device. The 11% and 15% may be appropriate for the Dynojet machines but personal experience tells me that the classic 15% and 18% numbers that I've always seen used seem to be more "correct" for the Mustang dyno that I've used.
Thanks again, Chris

Updated spreadsheet with ChrisM, haqs1, and fixed some errors/missing info I found. http://forums.bradbarnett.net/attach...3&d=1179198161

Updated with 36 more entries from this thread http://forums.bradbarnett.net/showthread.php?t=16676
Some new entries are pretty useful as they provide baseline/stock dyno runs for members with mods that I had already entered.
I marked the new entries in blue so that they would be easy to find. I also updated the average stock dyno worksheet.
On dynojet 5 speed stock GT with 20 entries
Mean rwhp/rwtq 271 291
Median rwhp/rwtq 272 290
On dynojet automatic stock GT with 5 entries
Mean rwhp/rwtq 259 267
Median rwhp/rwtq 259 267

Not that it makes too big a deal, but my one and only dyno run was made withOUT the Steeda UDPs. They were put on later. So the Lowe! 287/304 was just CAI + 93oct Brenspeed tune. Just fyi. Great spreadsheet!!!
