But If your going to compare numbers the least you can do compare apples to apples. The one you listed is for crank hp, NOT wheel hp which my graphs show. So the 034 is only putting down 430awhp, 20 less than mine.

What's my point? You asked for others to post dyno results. All of those will be collected on different dynos under different conditions so you can't compare absolute numbers on one dyno from those on another. You have to look at the deltas and compare them. (For consistency sake, I will use 1.20 (12/10) in the calculations below to indicate drive train power consumption, and .83 to reverse calculate wheel power from crank figures (10/12.). All of the figures below are for 93 octane tunes.
- Your dyno said stock hp at the wheels was 413. If you add 20% to that, your dyno says your stock hp at the crank is 495 (413 * 1.2). Since Audi advertises 444 hp at the crank, 495 seems wildly inflated.
- The APR website shows stock hp at the crank is 458, which is also higher than Audi's ratings. APR does not provide wheel numbers for 93 octane, but if you multiply the crank numbers by .83 you get 382 hp at the wheels.
- The 034 dyno numbers show stock hp at the wheels is 370. If you add 20% to that you get 444 (370 * 1.2), so the 034 dyno is calibrated similarly to the one used by Audi.
So, your dyno thinks the stock engine baseline is 495 hp at the crank, APR says the baseline is 458 hp, 034 says it's 444, and Audi says it's 444. And, since each of these dyno results don't start with the same baseline, you can't directly compare the peak numbers. You have to compare the delta. As an example, using the figures above:
- Your dyno shows a net gain of 37 hp and 43 ft lbs of torque at the wheels.
- APR shows a net gain of 32 hp at the wheels and 72 ft lbs at the wheels. Calculations were (40 crank hp * .83) (87 crank torque * .83).
- 034 shows a net gain of 60 hp and 57 ft lbs of torque at the wheels.
So, if you are trying to look at results from other dynos you have to pay attention to these differences when you try to compare one with another.
