137.5 bhp standard



  • hey all, just had my standard mx3 1.8 on a dyno at college it was putting out 137.5 at the fly wheel and the the wheel bhp was at 82 i'll try and get the picture of the read outs on here asap



  • I'm surprised! Engine must be running well :)



  • yeah i know i was really supprised

    sorry correction the bhp at the wheel is 81.2 and the torque is 171.8

    Did you get readings at the wheels and the fly? Torque seems unlikely, even it was Nm! Did you get a dyno graph? would be cool to see :)

    yeah i've got the print out here i'll try and scan it in and put it on here

    Engine power 137.5 hp
    Wheel power 81.2 hp
    torque 171,8 nm

    also did a speed test got it up to 136, but you couldn't get that on the road due to drag



  • I am inpressed with those figures, is your car a UK spec or Jap import car? The Jap ones produce slightly more HP, UK spec is supposed to around 130hp. Which I always thought was rubbish for a v6 1.8 when the likes of Escort GTi four pots produce that.

    Still they can't keep up with me anyway and I've had plenty of them try :twisted:

    Top speed of 136 sounds about right though. And you probably could do that on the road. The drag coefficient of the MX3 is very low anyways. I can also vouch for the top speed, I've done close to it! I've got 130 mph out of mine and still wasn't on the rev limiter but very close. Didn't take that long to reach it too and the car never struggled once to hit that speed. It just kept pulling and pulling till I took my foot off the throttle.



  • I've had 140 on a private road on a standard car as well. was just going into the red.



  • funny, my K8 100% stock gave me lower bhp on the flywheel …

    after some bolt on parts … the new dyno-sheet ... similar flywheel bhp, but your wheel bhp is very low
