Ok, looking at my charts, the air was less dense meaning "No" things were not the same, but that it was far from in my favor for getting big numbers. By looking at this, the numbers I did achieved are real, and there was even room for more if it wasn't so hot and humid.
You make a good point. I did have the car dynoed last in December on a nice cool morning. This tune was the day after the hottest day of the year. I know temp is not the only factor. But Im pretty sure if all things were equal, I would have shown even higher numbers. The fact that I just tuned under less than ideal conditions gives me a pretty good feeling that the car is not showing any "higher than they should be" numbers.
But I do agree, for mod to mod power gains, a corrected dyno is best. However, I like to know what I am at right now and what I will be racing at this time of year. I prefer an uncorrected dyno.
When I first started testing jet engines in the early 80's all of our corrections were done by hand, calculator and a pencil ( No Computers ). Now most are done by inputting uncorrected data into the computer and it spits it all out for you. I would still think that the dyno operator could pull up the uncorrected data as well as the corrected data and give you both sets of data. This could actually show you the difference between the two. You should ask what the standard is that he is correcting to ie. 59 deg day 29.92 inHg. There are other standards that may use 70 deg day or someting like that. The ones done to a higher temp and lower inches Hg will always show lower power numbers as compared to the 59 deg and higher inHg. Afew runs with both sets of data done on different days or better yet different times of year would show the disparity between corrected and uncorrected data. If you did a dyno pull on a day that the conditions met what the correction standard is you should see no difference between corrected and uncorrected data..
Before this swap I did the 1/8th in 7.8ET @ 88.5mph with a 1.80 60'.
Ron, I love smoking beamers. The drivers are so smug it seems. They never admit defeat even when loosing. It had to be something else. 8.21... that was a while ago!
7.8 is pretty good! I think you just might get to the 7.20's if you can hook it up.
I'd go right to the Phadt setup, I'd want the bottom line!
I wouldn't think it would affect mph unless it saves weight. MPH will show the HP gain.
ET is all about hook.
I believe you said the track you run isn't a real full time dragstrip?
BTW...I ran a kid in a 2013 M5 a few weeks ago. Reminded me of you and the Beemer you were tussling with. The kid wanted me. I beat him by over 10 car lengths. He follows me down the return road flashing his brights, pulls up to my pit spot and tells me I left too early and he wanted to try agian. Too funny. I had a .005 light.......11.25 to his 12.90. I said not right now...maybe later.
Haha, because he was sooo close...should have told him you'd run again for pinks or atleast he could pay for your fuel lol
