    So I was recently dyno tuned by flying Ryan performance here in Houston tx , my starting numbers were 415rwhp and final numbers after his tune was 450rwhp note on a mustang dyno if that makes a difference, question is am I about right on numbers with mods only being a exhaust , thanks in advance

    Those numbers sound about right. The silver 10 I recently built made 460/498 with exhaust only (catless mids and catback)

    ..spent most of this weekend at a local Dyno Dynamics Dyno facility.

    These Dynos read even lower than a Mustang Dyno but flip a "switch" to put either of these Dynos in "Shoot-Out Mode" and they are really close to what a Dynojet will read.
    If someone were to leave that part out in conversation, you may think "Wow" xxx horsepower on a Mustang (or a Dyno Dynamics) Dyno !!!

    Another Factoid: Some of the Fast and Furious crowd were getting higher numbers on a DYNOJET than a DYNAPACK. Go figure...

    So in Dyno-Land, there are no real absolutes, just generalities.

    Use the dyno as a tuning tool first and foremost. And that's been said many times before, for a good reason.

    If you picked up 35 wheel with a tune, that is good.

    As far as final numbers go...a dyno can be setup to give you ANY number you like, and that also goes for engine Dynos.

    But used "responsibly" they are very valuable for tuning. This is particularly true with a loading-type dyno like a Mustang, Dyno-Dynamics, or Dynapak.

    One "fact" : A stock Gen III (stick) Viper car typically makes 425 on a Dynojet.
    A stock automatic Viper truck loses 30 horsepower though the drivetrain and are typically around 390 wheel on a Dynojet.

    The rest of the data in Dyno-Wonderland can be "Subject to change without notice"...

    Track times, particularly MPH tell the real truth.

    Ronnie nailed it.... of course. I do have to say I think 450 is a bit high on a Mustang Dyno with only an exhaust. The day I had my 06 Viper on a Dynojet it only made 442 with a Corsa cat-back. I believe 4 or 5 other Gen III's dyno'd that day back to back and mine was the second highest (I believe one was higher than mine by around 5hp). If I was to have been on a Mustang that day it would have probably been around 400-410. I wouldn't be surprised if a Viper put down an extra 5hp versus an SRT Ram due to the lighter driveline, which would relate to 395-405. Just my .02

    In reality the drive lines are similar between car and RC truck. I've seem stock cats and truck do 440ish time after time on a Dynojet. 05 Quad cabs 415-430 and 06 QCs anywhere from 395-415.
    Torque around 495-505 on RC and 460ish on 05QC and 440ish on 06

    I strongly disagree! Even though the factory driveshafts in an RC are light thay are still probably close to double a Viper driveshaft, the rear axle in the truck definitely has more weight to the rotating components, and then most importantly have you ever noticed the weight difference from an SRT Ram rear tires/wheels in comparison to the car?

    I'm just telling you what I've seen on same dyno, same day from car to truck. They're within 10 hp of each other except for QCs
