    e30m52 First Dyno Run - baseline pulls

    Went and did the first dyno run with the car last week. Mustang Dyno, btw, and the print out sucks, its not very dark. I was a little nervous about it, since the only working gauge in the car is the tacometer.

    Did three pulls for baseline numbers.
    3rd gear from 2000 rpms to 6000 rpms. 6000rpms was the last run. the first two were 5000rpms.

    Max HP was 156 @ 6000rpms, but was still climbing....
    Max torque was 133 @ 6000rpms, but was also still climbing had I not been a waffleswaffleswaffleswaffleswaffles.


    1st run, the tech said it looked really lean, but the other three runs it did okay. I decided to shut it down at 6000rpms because I'm still getting used to the idea you can run a car motor that high in the rev range (i came over from the jeep world).

    anyway, after the third run, I checked the motor and found some oil on the pan and alt, which I believe came from the dipstick. I don't have anything hooked up to the dipstick where those two fittings are. The tech thought it was PS fluid, until he realized I didn't have power steering. I checked oil level and it was fine. I degreased and power washed the motor when i got home and there def aren't any leaks anywhere, so it had to be the dipstick.

    I've got some other gauges I'm working on making a pod for. Oil pressure, Volt meter, Water temp. Those are going in next weekend when i have some time..... if i dont have to work.

    How do these numbers look? This is my first experience with dynos. I'm planning on picking up a chip from Matt at TRM, just waitin till the end of the month for the funds.

    Motor is Alum M52 converted to OBD1 with s50 cams. m3 clutch and flywheel with e36 5spd tranny. 2.93lsd which I'll be swapping out with a 3.73lsd when i do the 5 lug.

    Sweet. Are you using the stock chip from the M50?

      yeah, right now.

      runs alright. I still have to find a home for a vac line.

      when i sit in traffic for more than a min, the idle all of a sudden dips, then runs rough. any idea what that might be?

        Vacuum leak or bad coil, maybe?

          Hmm, numbers are low, no? Hopefully you'll get the issue(s) resolved soon :)

          P.S. with e36 5spd, you don't think 3.73 is going to be way short?

            yeah, numbers seemed low to me too.

            Mustang Dynos are known to read lower than the others.....so ive been told


            again, this was just to determine baseline numbers. i def have some tuning to do, or chipping

              It certainly does seem low. I guess a lot of people say Mustang dynos read on the low side, but this probably wouldn't be healthy for dyno business if a dyno chronically read super low.

              An M52 2.8 with S5x cams should generally have around 200 whp or so on a Dynojet.

                I've got 235/40/17s goin on the car when i finish the 5 lug swap

                you think i'll be rev'n too high on the highway.

                Whats the website for calculating rev's / road speed/ wheel size......?

                  With those cams, that motor should make peak power in the 6500rpm range, which you havn't reached on the dyno. Plus it was a Mustang dyno which, as you mentioned, will read lower. With the motor sorted and a decent chip, it will perform very well

                    Are you saying that you have the 2 fittings on the dip stick tube open to the air? You should block those holes since they're causing a vacuum leak!

                      What exhaust are you running?

                        +1 I say you're down on power here. Don't worry about the rpm, these will r3v to 7000 easy

                          I'm running an ANSA exhaust for an e30, with e30 mid/cat pipe.


                          I had a feeling it was going to be too restrictive. I already talked to the exhaust shop about cutting that out and just putting it straight piped to a magnaflow.

                            Run that shit up to 7K! it will hold up just fine, no problem. With the S52 cams, the power band gets moved higher up the rev range anyway.
