There's typically a 13% difference between the two dyno's, say you make 200hp on a mustang dyno, 13% of that is 26hp, on a dynojet the same car will make 226hp. The mustang dyno is of a "street horsepower" measurementOriginally Posted by danewilson77

As you can see from my post with graph on page 3. I had some pretty shitty numbers for the amount of work I have done to the car. Idk what that is. I've done an exhaust since then but I don't think that changed the numbers significantly.
I ran the car at our local strip and the best number I could get was 14.5 at 95.4 mph. Granted I was spinning through 1st and part of second, even with an LSD but I expected my MPH to be a little higher. It was in the height 30s that night.

I would take it to a different dyno. Doesn't sound like they corrected the numbers very well.

Looks like you have power being lost somewhere. No trouble codes?

Absolutely true. All 4 of my dyno runs were on DynoJet dynos, and the last 3 were done by the same guy at the same altitude, though he did relocate the drum. Weather was a bit different:
Test 1: 75-80F, pressure and humidity unknown (different DynoJet)
Test 2: 83.7 F, 30.14 inches Hg, 21% humidity, SAE 0.98
Test 3: 63.0 F, 39.30 inches Hg, 66% humidity, SAE 1.00
Test 4: 70.0 F, 29.45 inches Hg, 29% humidity, SAE 0.99
The surprise to me is the only mod change was the aFe intake giving 9 or 10 extra RWHP when it's supposed to give about 4-5. Could be because I also have tune and pulleys, or could be one of the maintenance items I did helped (vacuum leak?), or could be variability in the dyno and temperatures. Between 2nd test (late 2012) and 3rd test (March 2014) I did GAS DISA repair kit, replaced CCV, changed transmission fluid, changed diff fluid, replaced guibo/CSB, and changed to stickier tires which were pumped up to a higher PSI (and tires might have been lighter too).

About 143,000 miles at Dyno test 1, 144,000 miles for Dyno test 2, 166,000 miles for Dyno test 3, and 186,000 miles for Dyno test 4.
Can't find dyno sheet from test #1 but my notes say my car measured 184 RWHP. Tests 2/3/4 used the same dyno but under slightly different conditions.
Test 1: 184 rwhp (100% stock, no fan on radiator)
Test 2: 189.5 rwhp (different dyno, fan and water spritz on radiator)
Test 3: 199.3 rwhp (pulleys, tune, lighter wheels, big fan on radiator)
Test 4: 211 rwhp (pulleys, tune, CAI, new CCV, lighter wheels, lighter tires, small fan on radiator)

Test 4 was in ideal conditions i see. That's a pretty good number considering the miles and amount of mods
