Guys like JoeZ at Carson Lexus, and Andy at MHP deserve mucho kudos for stepping up for us.

Fun times.....

Pat, the best RWHP I saw for you SAE corrected was 341 rwhp...is the 351 rwhp uncorrected?

Peter,

It was 351.41 STD (not SAE) and 0 smoothing.

Data directly from the Winpep7 printout:

rwhp = 351.41
rwtq = 336.25
Temp = 66.94 deg F
Humidity = 31%
Correction Factor = 0.99

I do not know what the calculated relationship is between "STD" and "SAE"

Default Tundra

Peter,

I think that the 341 rwhp you were remembering was the 4th gear run on the Tundra that was truncated at 5,200 rpm by the speed limiter. That run yeilded 341.63 hp for Mike's Tundra with v1 tune.

Sorry this is off topic, but it keeps the MHP thread on top!

Pat, STD is an inflated correction factor that NO ONE uses unless their goal is to inflate their dyno numbers. I believe you are referring to this STD graph of yours (not the Tundra's):



Here is that SAME dyno pull using the accurate SAE correction factor:



...and lastly, for reference, here is my 371 rwhp using the inflated STD correction factor:

Correct on SAE. When I get the winpeps from Pat's post tune dyno I'll convert them to SAE smoothing 5.

Thanks

So is it like nominal vs actual? STD being a nominal where SAE is the actual output?
