Virtual Dyno explained
« on: June 21, 2013, 10:11:53 AM »
This is a place holder for info on Virtual dyno and how we can utilize it for our cars by using SCT logs and 3rd or 4th gear pulls on a flat road to review our HP.

Why would you use this? If you're using a mail order tune you can take data logs for the tuner that will allow them to see what your car is doing. If you are playing with timing you want to get to a place where more timing doesn't add more power, you can only see this with a dyno. By utilizing this program you can get the car really close what the maximum output possible without spending HOURS for dyno time. After you think you're close THEN you head to the dyno to do some verification pulls. I'm getting my car dyno'd this week with the new turbos, I'll go out and do a log afterwords and do a comparison. Heck I'll do a log on the dyno for a comparison! :)

I thought the 2010-2012 non-PP SHO had a 2.73 & the PP SHO a 3.16.   Is the 2013 different?

Since I am running smaller diameter tires which change my axle to an effective 3.40, do I have to adjust everything by the tire diameter difference?
2010 Red Candy/White EB Flex.. World's first 12 second Brick.. 12.904 @ 106.85 MPH - October 2011
2009 Spt. Red G8 GT - modded. best time 12.074 & 114.02 MPH
2008 White G8 GT - mods... 8.32 1/8 mi.

You can edit the tire size.
If I have the wrong info then I can change BUT I got it right from the Ford Specifications list here:

I could be wrong, but that may be the non-turbo vehicle.

Added some how to videos in the first post. Bob if you can show me tech spec to confirm the SHO final drive I'll update.
I also need frontal area and drag coefficient for the SHO so I can make an XML file for it.

Added SHO.zip which has both PP and non-PP configurations (final drive 3.16 vs 3.39)
If this is wrong I can update later.

Played around a bit with this tonight, my final numbers were a little disappointing compared to what it spit out the first go around (3800+ HP/5000+tq)  ;D
I logged a 3rd gear run and ended up/with 399 HP 460ish TQ

That's what I would expect on an F-150.

You can do virtual dyno runs with ScanXL too. Never gotten around to doing it, but I know its possible. Of course I'd rather get a real dyno than a virtual one.

I have the App "Dash command", I had to enter data , ( like weight ect)

So I do not  know how accurate it is.
The one thing I do know the dealer must  must of had 87 in it, because I got better results on the next tank (93)   this was from that tank.

I started playing with this app yesterday, very cool! Interesting results.
Has anyone confirmed that the final gear on a SHO is in fact 2.73 & the PP SHO a 3.16 and not the ones in the XML which are 3.16 and 3.39
