Frustating / desapointing dyno r
Had anyone tried your car on a Mustang dyno? Iwent to this dyno cause they said this is the real thing this has a systems that simulates the ride on the street creating the same drag and making the car really uses his torque to move the roll, different than dynoyet, etc...bla, bla... So they said this numbers are usually about 15% less than numbers on other dynos. So, In my mine without considering this information, I was thinking about 340 for my stock car for my baseline. I did 3 passes, on 4th, on 5th and 5th sport mode. The peak showed in around 5300 rpm's 284whp / 284tq. On 4th it did the same, but then at 6300rpm went up to 293whp.
Can anyone share some knowledge here??

I had similar results. Made like only 298whp too. Was the hood open during all the runs? Also, did you turn off all traction? To do that, you have to do the "pedal dance" When my car dynoed low with those numbers, it was due to oil getting sucked up into my intake manifold from a aftermarket full oil catch can.

I had a similar experience. I found out my knock correction value was low.

Not enough info to troubleshoot or freak out about yet.
The car has so many sensors that if something is outside of range it will go into safety mode. More than likely it was seeing too high of intake temps and not enough cooling. However, it's impossible to tell without catalogs or live readings to see what was occurring.

What's the best and fastest way to get your knock learn up? Putting high octane fuel in tank (100+)?
I'm just kind of curious, last time I checked it was at around 19.
But it sounds like it might play a big roll specially when you are going to get dynoed. That might actually be the OP problem? Other than doing the pulls on the wrong gear.

Great posts, thanks. The catback already arrived and the intake is in shipping process. So, I'll try a dynoyet and fun it on 6th gear for the baseline run. Let you know...

Mustang Dyno's are heart breaking dyno's, they read lower than DynoDynamics and probably about 15-20% lower than DynoJet, so these numbers aren't bad, considering base 300HP STI dynoed @ 200WHP on Mustang Dyno and 260WHP on DynoJet so the numbers differ between dynos, but they shouldn't be used for power readout, they're a tuning tool that should just give you a difference between base and mods you installed.
