Which dyno do you prefer and why?
Which dyno do you prefer and why?
Which dyno do you prefer and why? We've all seen the Mustang in action, Dynojet, and DynoDynamics. How would you guys feel about dynoing on the new Superflow dyno that is load based?
If the dyno can provide solid tunes with OEM like drivability and reliable power, is that most important?
Or do you guys like being able to compare numbers with each other across the country, even though its pretty obvious that not all dyno's even when manufactured by the same brand show exactly the same numbers. Due to the fact that most dynos are calibrated differently, and have different correction factors applied.
Thanks!

DynoDynamics is first, they are just really expensive relative to the other. But it's money well spent.
Mustang is next and is the closest thing to a DynoDynamics.
Dynocom would be third since they are new to the game but they have a lot of nice features that could ultimately make them as good as the other two.
DynoJet is useless because it does not provide a "road" condition and the tune will be different between a dynojet and on the road.
i've heard very good things about the dd but never had a chance to use it.
i've also heard bad things too... like they chew up your tires, and that because the front and rear wheels aren't linked they can stress out you're awd drivetrain. this might not be a big deal on evo's since the power is always 50:50, but i hear on other car's that this is a concern.

Yea mustang is pretty kool in that the front and rear wheels are linked. and when you coast down it actaully goes into vacuum like it would on the road. unlike the dynapak.
have you ever had any problems with the software crashing on the mustang?

Mustang is a loaded dyno.
Can simulate 1/4mile sprint.
And it just looks rock solid

HA HA...that makes me laugh! The real reason is they can't figure out how to properly control a roller with very low inertia without having it affect their ability to maintain read the torque being applied to it, or accurately control a constant speed without over and under compensating...
The heavier the roller it is, the more inertia it has, so maintaining a constant speed is very easy. They can't do it with a small roller (or any size roller in my personal experience) so they try to sell people on the idea that you need a big roller to hold lots of power!
Thats a joke.....you can find numerous vidoes all over the internet of huge power runs being done on a DynoDynamcs with tiny little 10" rollers...
Also, you can find lots of other videos where people are having massive traction problems on DynoJet 248C's which have very large rollers and they aren't even trying to control the acceleration rate of the vehicle!
Obvisously its not about roller size...its about being able to control the roller, something Land-and-Sea hasn't figured out yet.
If you want to buy a dyno that actually works.....please do yourself a favor and stay away from Land-and-Sea!

MetPerfection, only time will tell whether or not your decision to purchase the L&S science project was a sound one. You have it now, so try and make the best of it. Hopefully your experience will be better than the ones I and several others have had.
I don't fault you for buying it, considering I once made a similar mistake.
My beef isn't with you or anyone else who buys one, so please don't take any personal offense.
If you are careful not to use it too often, it may even last long enough for you to pay it off before failing.
I truly want tuners to suceed, and I know that most people do not have the skills required to repair a dyno, so it is better if I can help more potential buyers beware of poor quality equipment before they find out the way I did.
My problem with them stems mostly from the way they treat their customers when their products fail to perform as advertised. Having previously owned one, I feel fully qualified to pass on this knowledge.
My sole purpose is not to "bash them" as you say, but to let people in this industry know the truth...and the truth is the L&S screwed over at least one customer (me) and I now happen to be in a position to pay them back for it by making sure that every potential dyno buyer gets the inside scoop on their junk before falling for their silly sales pitch the way I did.
You are always welcome to come to our site and participate, but don't expect those who know to sit back and let bunk information get thrown around on this site.
Land and Sea makes sub-standard equipment compared to the many other great dyno's out there, and no amount of sales tactics like "big rollers are the key to handling big power" is going to change that.
I have used almost every chassis dyno on the market, as well as personally visited many of their facilities, and I can typically make a more educated comparison of various dyno's than even the manufacturer's themselves can, because most of them have never used a competitor's dyno. So, when I tell you that the L&S pales in comparison to the DynoDynamics or Dynapack, you can be sure that the statement comes from much more than simply my distaste for L&S...it comes from real life experience.
BMEP: Those were some of the best posts I have seen you make in a while. Solid physics and good sound information is what this website is about. Thank you.

You could simplify the poll by saying "load bearing" and "inertial" as your two choices. I would prefer either a Mustang, or Dyno Dynamics myself, with third choice being the Dynapack (due to long setup time compared to my first two choices).
