I just got my car dyno'd earlier today and put down 250 wtq and 256 whp. It was Mustang Dyno.


The only mod I have is a K&N filter and I use Royal purple 5-w30.


This seems pretty high to me. How underrated are these cars from the factory. Anybody putting down numbers for their stock LNF that are higher?


On a sidenote, it appears that most of you are making more Torque than HP. Seems like I am unusual in that respect.

 

regardless of mods, all stock tune SS/TC are limited to 260hp/260tq by the ecu.

your numbers are very close and every car varies a little. dont obsess about it

 

not all dynos are accurate

the LNF is 3rd party verified to be what GM rated it per SAE J2723

 

most dyno about 240whp

 

and the ecu cannot detect horsepower nor torque it just limits air flow they try to keep it constant

 

Thats not a WHP rating though.

He did put down more then the average, usually they are about 245 stock to the wheels.

 

yes its slightly high, but still well within normal. definitely nothing to complain about, regardless of whether it puts out more tq than hp.

the ecu doesnt detect hp or tq, but it uses airflow numbers as an estimation and strives to achieve those airflow #s by adjusting the "output" of the turbo. the ECU can increase airflow as well as decrease to achieve the desired airflow #s.

 

Well not just airflow numbers - temperature, timing, etc are all taken into account to estimate 260 lb ft of torque. It doesn't try to limit HP. BTW most of the dynos I've seen so far are showing the stock trq to be about what this poster got (and what I got, see my sig).

 

Those are very close to my stock numbers: 253 whp 247 wtrq on a loaded dynocom dyno. These cars are underrated from the factory.

 

That seems about right. My #'s are in my sig. Thats without the k&n btw. Probably lower with it now

 

are these number corrected(sae) or not?

seems a bit higher than average, especially for a mustang dyno, which typically reads a bit lower than a dynojet

 

Mine was on a DynoDynamics and put down 228hp. These may seem low to anyone else, but to me these number are spot on. Your numbers are fine.

 

I believe those are the exact same numbers i put down, where did you get it dynoed??
