New Plenum test on the way!
- Thread starter 03trubluGT
- Start date
I was absolutely shocked when the first run was made with the stock plenum and TB and I hit 265 HP. That's what I made with the Accufab and 70mm TB last dyno.
I can't explain it.
I can tell you my numbers are without reproach. I did this test (and wrote the check to Speedworks myself) so that this info would be dead on and honest. No magazine money, no advertising dollars.
This test was done for us little guys, and if you start attacking my credibility, then do your own test.
I spent $210 on the dyno, $13 on gas, and burned a holiday at work so I could be off (at the expense of over $240) for this test, not to mention the 20 pulls on the car (the first pull was aborted becuase the a/f reader was off, and one of the later pulls was aborted because the EGR was not sealed) and wear and tear. And to top it off, it took me 1 hour and 45 minutes to get from Speedworks to my son's baseball practice in Mansfield(which I missed half of).
My test was run as accurately as I could.

No one is attacking your credibility. It's cool that you are doing this. I am just beginning to question the validity of dyno results in general. What could explain your baseline being 9rwhp higher than your last baseline? Here are a few possibilities:
- different rear tire pressure (affects drag on the drums)
- different strap down pressure (affects drag on the drums)
- cleaner oil this time?
And last, but certainly not least, they dyno is out of calibration. I think lots of shops don't keep their dyno within the manufactured specs. While I am not a dyno expert, I have to believe that after x amout of dyno runs on a machine, the drum eventually needs to be brought back into spec.
That's probably explains why guys post wide ranges of dyno results when we are all using similar mods. and we all have GT's. The range likely comes from the different dyno shops, not the from the mods. and not from the cookie cutter Mustang GT.

This oil had about 1100 miles on it.
The last dyno I did I changed the oil the day before.
I don't know if that might have something to do with it

Tomorrow I compile all of the info and e-mail it off to be compiled for the article.
Sorry for making you guys wait, but I think the article will make it worth while.
