BHP = no accessories at fkywheel
SAE Net = with all accessories at flywheel
STD = rear wheel horsepower with ZERO correction (in this case)
So the 152/149 are actually a bit higher than you might expect for a car rated at 168 SAE Net by BMW. Does anyone else have dyno sheets for a stock or mildly modified m20b25?
Yes, we will design and install the CAIS on this car but it was primarily purchased for the turbo kit development.
Very similar to my stock motor's run. I put 150/150 to the wheels on a DynoJet. Sounds as if you have a stout motor to be boosting, best of luck!!

Most people do post SAE numbers to get an equal comparison to others around the country. STD #s will always be ~4% higher than SAE since they use a different correction factor. The Dynojet software allows you to correct to between SAE, STD, DIN, and actual (uncorrected). The actual numbers are exactly what the car put down on the rollers on that day with the current atmospheric conditons.
SAE corrects to: 29.23" Hg, 77 deg F, 0 % relative humidity
STD corrects to: 29.92" Hg, 68 deg F, 0 % relative humidity
DIN corrects to: 29.33" HG, 68 deg F, 0% relative humidity
You can compare SAE with SAE or STD with STD, etc. but none of them ever with each other. Actual numbers can't be compared to other actual numbers unless done at the exact same time with the exact same conditions, which is almost impossible.
