Finally dyno'd the Cat today. I was very impressed and here are the details :

M6 HC Challenger
1030 miles
82 degrees / not very humid
Dyno jet - SAE corrected - not STD
Stock Autos have made 640-660 whp on the same Dyno.
13/14 GT 500 made 558whp

First Dyno was 680whp.. Second was 683whp and then the last was 686whp.

I have attached the graph.... Thoughts ?

Dang good

That is outrageous! The 13/14 GT500 number seems kind of low though. Probably one of the lowest I've seen, most are in the 585-605 rwhp range for a dynojet dyno.

Great stuff! Get on the AFE group buy for the air intake and then dyno again. Would love to see the end results; independently tested.

I agree... Thought it was low.

Nice! I just did a 529 on a stingy mustang dyno yesterday. A TT Gallardo did 468 and a V8 TT BMW M5 did 447.

Jumping on a dynojet tonight. Looking forward to seeing the difference between the 2 dynos.

Dang... That is incredibly stingy.

Terrific numbers. Do you know, based on the boost guage, what amount of boost? When I drive my M6, it only shows 10lbs of boost at full throttle, and my car doesn't feel as potent as others describe their Hellcats, maybe my car does not make enough power because of low boost?!

 

[Puffy]

Dang... That is incredibly stingy.

True. I was told they factored in every influence that would affect the power. Comparison test tonight.

Why don't the TQ/HP curves cross at 5250?

Not sure :-(. Could have been their calibration ?

I am actually not sure... Because it's stock I really have not paid attention much to it. I wanna say it's seen 12-13 but I can't be certain.

HP measurement on the left of the chart, TQ on the right and they are at different intervals.

ahhhh... Good catch.

Here is a quick video of the run.

 

[hellcat1]

That's incredible,,,I would be loving that kind of power... do you feel the car opened up more around 1000 miles...

My car has almost identical miles on it as your's did on the dyno, coincidently. Maybe you could pull that screen up, between the tach and speedo, with pounds of boost, next time you're out doing some joyridin', to see how much pressure she's crankin', as I don't feel like my car is quite up to muster and if it's not making the appropriate amount of boost then that would sure narrow down the cause! ~ Your 'cat looked and sounded sweet on the dyno!

DAMN.

 

[buddyg]

Dynos are nice but get it to the track.

I have trapped 122mph on street tires , 40psi, 2800 DA and bounced off the rev limiter lol... Need more seat time
