Hey everyone this thread is going to go out to are sponsors. I hope they will participate in this and help some to understand this process.

First I am going to kick this off with what I know. From doing some basic research I have come across the basic dyno companies, Dynojet, Mustang Dyno, and Dyno Dynamics. Now the part that gets me is all do the same basic thing and that measure whp, BUT none give the same reading. A Dyno Dynamic reads averagly 10-15% lower then a Dyno Jet. Also the Mustang Dyno reads a little lower then the dyno jet. This brings up the true ultimate question, and that is which one is the most accurate? Also why is there no standard set to these systems? Alot of people take there car to the dyno to get tuned, as others want to see what there car is putting out. It seems to me there is so much deceiving going to here that I find my self not knowing what to believe. On lets say a stage 1 turbo kit for your car, the retailer advertises 500 rwhp. Well maybe on the dyno he is running it on it does that but if you take it to a Dyno Dynamics dyno your running 10-15% lower then that. In my eyes thats kind of deceiving because your purchased a kit that does 500 rwhp. well the manufacture did all test on his lets say dyno jet so he isn't lieing, BUT WHAT IS THE TRUE WHP RATING? Do we just pick the graph that has the highest rating because it makes us feel more awesome or to make us feel better because no one wants to spend 7-8 grand on a kit and get 380 hp when 500 was advertised and your goal was 500. My point is there needs to be a standard between each company, and they should be able by now with technology to simulate a car driving on pavement.

OK I am now done with my ramping and this is the part I would like are sponsors to jump in, since they dyno cars every day.
First I would like to know what dyno your company has chosen.
Second, I would like to know why you chose that dyno.
Third, how does it compare to the other type of dyno's out there
Fourth and final question, which dyno do you think gives the most realistic results.

Any answers to the questions above would be awesome if you choose not to answer all of them. This is not for me or anyone to try and say the parts you sell are lieing about there actual hp rating but to educate us all.
Thanks
Frank
