Here's my dyno sheet with my SRT6 in stock condition (BASELINE) and after adding a NeedsWings dual cold air intake, 178mm pulley with pulley saver kit, and a Eurocharged "Tony" tune from his January 9th SF Bay Area visit.
The dyno was at 034Motorsports in Fremont, Ca. The dyno is called a "Land & Sea" and the guys told me it was similar to a "Mustang" dyno.
The before and after dynos were both done at 034 with the same guy running it both times. The ambient air temp for the baseline was low 50's. The temp for the run with the mods was hi 50's.

Hopefully the attachment worked

The post mods dyno was done today

 

That looks pretty good! Those numbers would be much higher on a dyno jet.

Well done, now go run some LOWWWW 12s!

 

Great numbers, but why does hp fall off after 5500rpm? Did they stop the run early and if so why...

 

Those are great numbers! Even better than some that have done a lot more mods...

 

Looks a bit lean down low, and again right before the test stopped

 

Looks lean down low because that is how a dyno works. You throw a dyno fan in front of the car pushing winds at 60mph or whatever it is and then you aren't actually accelerating at that speed your air/fuel will be off... it is how the car was loaded (the acceleration) before the test ran into the corect RPMs around 3000...

I do not believe it will be higher on a dyno jet. Those numbers look like the mustang dyno was already calibrated to read similarly to a dynojet. Those mods do not indicate a higher dynojet reading given historical dyno data contained in this forum


my $.02

 

i dyno'ed my old car locally on a land and sea and then locally on a dynojet and the land and sea read much higher. they are scarry to get on too, little tiny wobbly dyno. everyone else that used his L&S dyno'ed higher on it as well. i am not saying it is the case here but that was my experience with them.

 

you have a 60+ hp AND torque improvement?!! thats awesome!!! tony has really got these cars down to a science. makes me think mayb e the 178 is were i should be leaning towards!

 

Leaning would be the correct response....lol...

 

Steve, a couple of things to consider. His baseline HP is before the pulley and CAI, so the 60 HP increase includes the Pulley, CAI, and tune. Also, it appears that the dyno that he is on produces higher numbers than a DynoJet. If it is like a Mustang, that would be the case. You are looking at apples and oranges here if you are trying to make a comparison to our Atlanta results.

 

no bob not comparing just ballparking. just seeing a large inc. with the 178.
my baseline was on a mustang with no mods and i got 321 hp and 317 ft/lbs. so after his mods lets just say 40 + inc. not bad at all!! but dont worry im in no hurry to rip off my crank pulley just yet. ill wait a yr or so and see how they hold up. BUT if i did the 178 would be my choice

 

Just wanted to put up some before mod and after mod dyno info
to help folks in the future with their potential modding decisions.

 

And thanks for doing so. Great results by the way. I am sure it puts a smile on your face every time you get on it. Kudos to the Eurocharged crew once again.

 

Yeah, a big smile and a shake of the head 'cause it's stupid fast off the low end

 

Well that's the case or he has the most powerful SRT6 ever recorded. Timeslips will be interesting.

IMO, dynos are somewhat abstract without a baseline. It's cool to see his baseline vs. the power it made after the mods were installed. Thanks for sharing!
