    Guys,
    The car is a 1989 325i 5 speed with 148k miles. Bone stock but in excellent running condition.

      DynoJet 248C. We use the same dyno for all our runs. Temp in the bay was about 50F.

        Re:

        That's ITS power range! I've seen a few in the upper 150's but thats w/ open exhaust.

        525 DME perhaps? My silver car picked up w/ 525 vs 173 stock to stock.

        Any strips still open?

          Totally stock in every respect including ECU. ATCO in NJ is open all winter.

            Good number for an M20.

            What does it run in the 1/4?

              Have not run it yet. I'll be taking it to ATCO after we put the turbo on.
              Thanks,

                Nice numbers! Is this the test car for the CAI?

                  Nice, but they are STD numbers, not SAE, so they are a little higher.

                    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.

                    Thanks,

                      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!!

                        Nice #s for a stock car!

                        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.

                              We are going to ATCO on Dec 13th with the 535i. That would be awesome if you could make it.

                              Jason, I asked the shop to convert our sheets to SAE for comparison.
