At MZM they use 14.5 hp at 50mph at 3400 lbs.(+/-) vehicle wt. and I make about 260hp. At Wasabi I made like 299hp. Both have Mustang Dynos, just use different set-ups.
Do you know what they use at FIS?

You should really only look at dyno numbers as a basis for how you have improved your car. Not who's got what big numbers. I'm not saying this how you perceive dyno numbers, just presenting a way to keep it real.

I had my base dyno done at FIS though, so I'll just keep going back there when I'm curious about MY numbers. I think the only real way to believe dyno numbers are to use the same one all the time, and only compare to other cars who have used that same dyno.

My mistake, I was thinking in crank hp, not whp. A test pipe by itself would definitely NOT add 20whp!

The MD 7100 which is what we had was calibrated to be as close as possible to real world driving.
FIS has the previous version of ours and I am sure they are updated as well.
In my opinion if a EVO is laying down 300HP on a Mustang then be looking for 360-375 on a Dynojet. There are a lot of varibles in getting the same number.
- You car maybe sitting in the shop and the motor as well as tires are the same as the ambient temp.
-Ambient temp and humidity is also a big issue.
-Fans and cooling on the car is also a factor.
-Rolling drag on the dyno
Basically it's a small glimpse of power at a certain time. On a dyno day ( driving the same type of car over and over) you may see 3 different numbers on 3 different pulls.
It's merely a gauge; to some degree a platflorm so you can say what power is what when changing diffent mods or progamming on the ECU. I am no tech, this is just experience from what I have seen and heard from very trust worthy sources.
Good Luck

i would say almost all of the time you will not get a cop that will get on his knee's and look under your car...if anything you might get a $40 ticket for having a "loud Muffler"
