Looking at weather from today, the correction factor would have be .98.
So not that big of change, Good weather.
I have the correction factor equ. at work and I'll try to remeber to post it tomarrow.
So not that big of change.

Like it has already been utter here, SAE numbers are the only numbers to use for comparison.

 

FORGET the SAE/STD conspiracy for a minute... WHAT ABOUT the dyno plot?!

Why does it look like the chip is making LESS HP and TQ from 2K to almost 3K, it wakes up from 3K to 3.5K, but then from 3.5 to redline, its just a SMALL increase?

From a "total area under the curve", it would seem the two are no different?!

What am I missing?

It looks very much like the PSP chip has hurt performance under 3k rpm. On the dragstrip I'd imagine it doesn't matter too much 'cause most of the time higher rpm are in use, but for impromptu events where the rpm aren't there it has got to be something you can feel... probably has the driver downshifting more than he would ordinarily. PSP chip owners, any more on this?

Hey guys, Sal here. Looking at the graph, it looks like the dyno operator hit the record button before going to WOT. When you dyno a vehicle, you get it rolling to a good speed, then you go WOT at a point where your readings should be taken in direct drive. Since this dyno was done at a rice shop, the operator obviously is not familiar with dynoing a Lightning. Seems like he hit the button around 2k and then went WOT at about 3k.

RED2000SVT- I went to Motorsports today and made two runs on the Dynojet. The deal was for 3 runs but they change it to 2 runs when I was paying. I wasn't happy with that change in price! But my stock bolt matched your Baseline settings for Torque and low 2.6 HP for Max.

Max Torque 413.9 and Max HP was 337.4 on the first run (Best). I had the same correction factor as your runs. And I only have less then 2300 miles on the engine break-in.

Looks like a Chip and Filter down the road.

You cant measure the Shift firmess with the dyno that Sal's chip provides, (HUGE DIFFERENCE) as well as no having the power robbing 4 cylinder drop at wot shifts, which is eliminated with his chip as well. I don't claim to feel my Buttometer on to many mods, but Sal's chip (10 or so hp on the dyno) feels like about 50hp when on the street. Again the shifts and no cylinder drop make a huge difference.

To those who said I was wrong about my numbers being corrected, YOUR RIGHT!! Hehehehe. The dyno guy still insist they are corrected but I believe it when everyone here(everyone, including fello Stang guys) tells me STD is uncorrected.

He did however show me that there is a 1.04 correction factor. It was 82 deg and about 70 on the humidity so do I times my STD #'s by 1.04 or divide by 1.04?

Looks like this guy changed his prices for Dave, dont think I'll go there again.

Red2000SVT,

Well it sounds like to me the dyno operator might be happier showing you higher number than accurate ones.

I’m sure you can find one who is honest and not afraid to tell you how much real horsepower you are really making.

And to boot, he will stick by his prices for dyno runs for everyone!

Good Luck!

If you have a 1.04 correction factor then your ACTUAL #s are _less_ than the corrected #s. Period. To have a positive correction factor means you dyno'd the truck in _worse_ than SAE net conditions (like 72^F, 29.92" baro. press., etc...I don't remember it off the top of my head).

82^F, 70% humidity, etc stinks. That is crappy air.

Now, the trick is making sure dyno operators don't fudge on the correction factor, but most of them don't.

If you had a 0.97 correction factor (dyno'd in excellent air), then the actual would be _higher_ than the corrected #s...I've seen several dyno operators print out the actual #s for people in this case b/c they are the highest set of #s.

Then my #'s are the uncorrected x 1.04.

Cool, even better

Thanks.........

I looked at your weather report and calculated your correction factor to be: .98


Your power x .98 = SAE corrected

 

yes, see this is the problem...dyno operator error. I don't claim to have the formula for correcting weather conditions back to SAE, but if the dyno operator claimed 1.04 and it is really .98, then there's some fudging going on.

IMHO, it seems that 80^F, and 70% relative humidity would stink, but I know baro. pressure really seems to be the biggest factor. Above 29.9x is good, below 29.5 isn't too hot. Some guys on the east coast running incredible times routinely see 30.xx" baro pressure. That is awesome.

Thanks Sal,

That makes sense for the 2K-3K region.

But is it typical to only get an additional 10-12 hp (thru the RPM range).
