Viggen Dyno

I guess you could say that the Nordic software puts down good power. We made 287hp and 340 ftlbs at the wheels. With standard 15% drivetrain loss that is 340hp and 400FtLbs !!! I was a bit surprised so we made a few more runs just to be sure. I posted a bunch of videos and car details on my TrollTuner.com site. Will get the charts up tomorrow. The key is matching hardware mods with proper software.

This explains why I was having such traction problems after changing back to stock P6000 tires for winter.

Good stuff.., and that's a lot of power....(not to quibble, but I calculate 330hp and 391...given 15% drive train loss.) :P

Real curious to see how broad your range is, and see your air/fuel ratio. Cause that's one hell of an achievement... with a T7

Take 287 and divide it by the inverse of the loss (85) that gives you 1% of your power multiply that by 100 and you 337.6hp and do the same with the torque and you get 400.

I believe you are correct... I multiplied 1.15 * 287 to get my figures. ...when you divide by 85% your numbers at the crank are represented ....but really doesn't matter, because the only thing matters is the wheel hP & torque anyway.......

I guess it really does take an ECU to squeeze the numbers out of a t7 ...after hearing the complicated stories about them, didn't think it possible to get these kind of numbers.

Have to wonder if he using the same IC setup...didn't get a chance to review the upgrades...

Technically "u" isn't a word either, and "U" used it twice. Know any Scandenavian words not pertaining to Saab?

Remember, you are calculating a LOSS not a gain, so you would take 340 and subtract 15%, not take 287 and add 15%. 15% of 340 is more than 15% of 287.

A 15% loss would actually be ~ 338, but who's counting.

338 - 15%(50.7) = 287.3

I like to think of it as whp is 85%(or 100%-drivetrain loss) of the total. That's how I remember it, but I still get confused from time to time
