4.6L Dyno Results

So I finally got a chance to throw my 4.6L on the dyno at my office tonight. I posted recently about a track outing that the car ran a conservative 14.2 as I didn't want to push it to the limits on the launch and was asked if I can get some dyno results since I have easy access to a dyno and haven't gotten around to modifying the engine at all yet so we can get a solid baseline for what the 4.6 will push out. So long story short I had runs measuring in between 296 and 315 just depending on how the trans and ECU hooked up each run with being confused on the dyno, one of my company's in house tuners was saying that the car was messing with the torque converter's output since I only set it up for the rear tires to roll and it was throwing all sorts of ABS and ESC lights. So after combing through a couple runs dialing the car in to where it likes to be on the dyno we got what we feel was the most realistic idea of actual output to the rear wheels. One run with 308hp and 295 ft/lbs and another at 311 hp and 293 ft/lbs The cars gets a little funky around 4500 rpm when it is deciding what to do with the engine's timing which is easy to see on the graphs. The following pulls were a 4th gear run and a run through 3rd and 4th

Glassman this very useful data, it is interesting that your numbers matches almost exactly with Tailwalker's Dyno run after his intake upgrade!?

Few questions:

- Are using a stock filter or K&N/after market filter?
- What was the ambient temperature?
- Did you have a fan in front of the engine during these runs?
- Was the engine warmed up to normal temperature?
- Was the hood open or closed?

You mentioned that the ABS & ESC kicked in, is there any way to to redo that test with the ESC fuse pulled out (only if you are comfortable )?
It will be interesting to see if there is any impact on the Dyno run...

From my OBDII data gathering and analysis, I suspect that the ESC does have some impact on the overall HP/TRQ output, but only a Dyno run would show that for sure!...

That is all stock, the filter is the normal OEM filter, it was swapped out less than 5,000 miles ago so it is clean and still flowing well.

Temps were right at 73 degrees in out dyno room with the cooling fans blowing at the car.

Engine was warmed up with some driving around the office and a few pulls before we started taking data.

I did runs with both hood open and hood shut with very little deviation which confirmed what I had already tested at my previous company that a limiting agent in the intake on the Genesis is the fresh air ducts letting air into the airbox.

Next time I get get the car onto the dyno for intake or exhaust testing I will try pulling the fuse to see it the nanny system is limiting power output. i don't believe it will make much of a difference as I tried pulling the fuse at the drag strip and saw no noticeable difference in second half times with ESC engaged versus the fuse removed implying similar top end power output.
