FBO 2019 SS 1LE, I expected over 500whp - Page 2

7speed · 09-04-2019, 04:38 PM

So SAE more like 475whp / 456 Tq, not bad at all

oldman · 09-04-2019, 05:04 PM

untill an uncorrected dyno is published or one that has the applied correction factor, there is actually no telling how much HP the car produced.

NickeyMatt1LE · 09-06-2019, 03:35 PM

Looks like standard correction factor was used. Sae would be around 485 hp, 465 lb/ft.

oldman · 09-06-2019, 04:20 PM

assuming the dyno was setup with what was the actual pressure, temp and humidity at that time. How do you know the CF was not 1.30 or something. It is not published. CF should always be single digits at least IMO. I'm skeptical of any STP /STD dyno with no published CF.

NickeyMatt1LE · 09-07-2019, 01:08 AM

Dynojet and Superflow have a weather station as part of the electronics. The correction factor is based off that. It is not based on numbers or data you can enter into the software. There are some dynos where you can manually enter correction factors, but that takes out the repeatability of the dyno which is the whole point of having one. There is nowhere in the software on our dynojet that I can alter the correction factor numerically or alter the current atmosphere reading. I can simply choose which correction to apply. SAE, STD, DIN, JIS, or uncorrected. Assuming op's not at a high altitude, correction factors for STD usually range 1.03-1.05 in the summer months in the US. SAE is usually 1.02-1.04.

AFAIK you can manually enter weater data. Can't speak for every dyno and piece of software. No CF and STD / STP means NOBODY can tell what the actual HP was or is. Just IMO, glad in your confidence in dyno numbers with no published CF.

Agree on the .03 to .05... disagree that we know what the CF is here as it is unpublished, when not published, I tend to discount it especially unpublished STD , STP et al.

You are looking at this the wrong way. Expecting 'over 500whp' when you have no baseline is really a foolish internet hp mentality. If you had done a baseline and that particular dyno said 440whp for your stock car, then in that case, you'd have reason to believe that you'd get a high number after the mods, because the dyno would have already shown itself to be optimistic. Without a baseline, the final number really is meaningless.

See, I see this completely differently than a lot of other people. I really, really don't care about 1/4 times and I don't see that as a viable metric for the performance of how I would judge my own vehicle--because I loathe drag racing and I would never partake in it. Therefore, dyno readings are the only real way I could see the power benefit of a given part or series of parts. With that being said, he should have gotten a baseline to have a more accurate assessment of his gains.

The point that was trying to be made earlier in this thread is that all dynos are different. There is no global baseline dyno to compare numbers to. Only a baseline on the dyno you are using in hopefully the same DA.

And furthermore, dynos should only be used to measure power gains and loses. To compare numbers to other dynos or even the same dyno on a different day, is pointless. Like said, visit a few more dynos and im sure one will say you make 500rwhp.

Man a cam would have been an awesome add, not bad numbers though for NA. Live your life, **** these punk bitches.
