F55 (Magnetic Ride Suspension) option working it’s magic! Were you running in "Sport" or "Tour" mode?
I worked it in both. But I did not put it back in tour after I found the tire pressure. I am going to play with it some more. But it really worked well in both.
did i understand that this was your first trip to the 1/4? Not too bad for a newb! To sum it up...
You have a 2011 grandsport coupe with a6
you have arh headers w/cats thru npps
you have nitto nt05s
you have the lg motorsports g6xb complete blower cam kit
you have the edelbrock 1591 supercharger
you have upgraded from 52lb to 65lb injectors
you changed from the 3.5" to the 3" pulley
you upgraded the fuel flow to feed both rails
"the tuning school" tuned your car with a 584rwhp final number on a conservative tune
you are running 14 degrees up top with an afr of 11.7-ish
Well that should silence a naysayer or two for a while....one in particular comes to mind. Guess you overcame the....
- "Heat Soak Pig"
- "Can't use all of that torque that early"
- "All of that extra weight"
- "Blower is maxed out"
- "Loss of boost pressure during shifts"
Great times!I also read your thread regarding the Rattle in your e-force.I have a 1593 unit on my 07 / a6 coupe,same rattle or growl
that you describe.Notice it only at running temp while slowing to a idle.
Edelbrock said it was a normal vibration.I've got about 1000 mi. on it and it has gotten much better.I have no other complaints.My car is stock except for exhaust.Love it!
Normal setups will most likely suffer noticeably from heatsoak after repeated runs.
It's not the quarter mile runs that cause the heat soak. It's the idle time and burnout before the runs that are the culprits. That makes sure everything is nice and hot before the quarter ever starts. I've run the snot out of mine on the street in 95 degree heat and never saw any excessive heat or timing pulled. The difference on the street was that I had air going through the h/e before the runs and did no burnout.

Even the idle time and burnout isn't that bad on it, I can make 4 back to back dyno pulls after allowing the engine to get warmed up to 200ECT, the first pul will start at ~80 IAT, at the start of the 4th pull the IAT will still be below 110.
What really kills it is when you cut the engine off after making the pulls and the airflow and intercooler pump stops. After 15 minutes of the key off it's not uncommon to see 140+ IAT's...

Sit in line for more than a few minutes with the motor at idle and OAT's 80 degrees +. You can pick your poison. Kill the engine and wait for a while to start it and move up....or leave it running and ease up. Either way, there's not a lot of air moving through the h/e. The coolant in the h/e system is going to be toasty warm when it's time for the burnout. It just goes up from there. 150 degree IAT's at the track during the run in 80 degree weather (timing pulled). Vs 130 degree IAT's on the street during back to back high speed runs in 95+ degree weather (no timing pulled). If I spent more time at the track and my track times mattered, I'd already have meth. Because I don't and it doesn't, I'm going to leave my rig simple. Meth is just one more sub-system to have to keep track of.
Just got back from a thousand mile trip. The vette averaged over 26mpg (hand calculated) for the entire trip. Got over 30 on one tank with a tail wind and slow speeds (60 mph speed limits across a Louisiana swamp on elevated section of I-10/12). That's just amazing to have something that runs this strong that is still our "economy" car.
