very ambitious mustang dyno numbers. not typical for stock C6.
What's important is there's some improvement post tune. that's all that really matters, but those #'s are high for any typical Mustang.
They're even on the high side of a Dynojet for that matter.. hope the tuner is good to you, whatever other improvements you make be sure to use THAT dyno otherwise you could be looking for answers, say you put a set of LT's on it and it gains say... nothing (on another dyno) lol...
And yes, i agree with you on the trans tune. My tuner goes a step further in the trans tunes. He had a GM Engineer fly in and tech him how to tune the 6 speeds (some years back). My tuner fixes many jacked up trans tunes in the tri-state (and beyond) area by people who just "learn as they go" on your car lol
Those numbers are 30-40 rwhp more than I would expect from a Mustang dyno. Happy dynos are fun, but meaningless for real comparison with others' results. A stock LS3 auto on a typical dynojet will drop 370-380 rwhp.
I was actually the one who tuned the car. I always tell people not to get wrapped up in dyno numbers too much and always use the same dyno to see gains.
Glad i could take care of you Ron. I know you love the Trans tune like all my customers.
After results: 455/446
2008 C6 Auto 6L80E, stock stall, NPP
Comp Cam Custom grind road race cam with QXI/QXX endurance lobes
American Racing 1 7/8 Headers
Haltech 105
The Dewitt's radiator with oil and tranny cooling and dual fans work great, the thermostat is actually controlling water temperature. Oil and transmission temps are 20-30 degrees lower than before on the street. Oil pressure is up 10psi.
NPP off and it's some serious muscle car time. Exhaust at idle has a mild, just right chop in neutral that subsides in gear. Idles great @ 800 rpm. Full throttle could make a Prius driver burst into spontaneous combustion. Very distinct exhaust note with a nice hard kick in the pants at WOT and a Godzilla like scream. Very strong and consistent torque mid to high range RPM.
The Comp Cams QXX/QXI track/street cam lobe profiles generate an Exhaust note that've is unique in a good way with some high frequency rasp, almost exotic (Ferrari) like. Pulls like a locomotive and feels stronger in 3rd gear than it did previously in 2nd. My right foot is very happy and I will be grinning every time I fire it up - looking forward to getting it on track in a couple of weeks :-)
With the NPP, the car has a Jekyll and Hyde personality. NPP ON and normal driving it's almost stock like and will keep the right seat happy on long cruises. A little more cabin hi freq noise from the headers but no drone. DIC showed 30 mpg on the highway @ 70 mph steady throttle, no change from before.
A huge thanks to Shane and Greg @ Craven Performance for making it happen!
The results on track were very good, the carperformed flawlessly at Gateway. Several people commented on how good the car sounds.
Temperatures were good hammer down full 20 min session:
Street:
Oil 198, coolant 176, trans 172
Track,
Oil 244 (309 before after 10 min), coolant 190, trans 223
Top speed was ~145, previously ~135. Lap time dropped a little more than 2 sec with further room to improve.
A couple of SCCA PDX videos to show what it sounds like outside and inside the car, the rate of speed passing the 911 is high mostly due to the driver lifting for the pass as required in PDX:
