I have a question for those that took their shos to the drag strip. I am wondering how far do you let the rpms raise before you shift to the next gear, from 1st-2nd/2nd-3rd/3rd-4th, and if you hit the 5th gear in a 1/4 mile? I just recently started getting familiar with this car, and I do not want to hit the limiter. I'm sure most of you know the feeling of having the nose down(of the car) at the redline. Not pretty, therefore, where do these cars shine in the rpm level to get the most out of them? And, I should probably add, I am completely stock. But do comment if you are tuned, just please state so.
Let the computer do the shifting. Can't beat it.

seriously, it'll go all the way to the redline and shift on its own? I assume it has to be in S position? So what is the purpose of the paddle shifter then? Sorry this is my first automatic, I have too many questions.
Thought the same too after reading on how the car does it better than we can. I use paddles only when racing from a roll so I'm in a good gear instead of getting the hesitation.
Rich
So what's the trick, keeping the gas paddle to the floor and never let off? tell me more, the whole story, lol, from start to finish...
Brake boost at 2200 rpm's and then take the skinny happy pedal and try to push it through the floor...lol
Rich
brake and throttle to 2200 rpms is safe? I think I read somewhere that 1800 rpms was the limit...
Nope 2200 is fine.
Thank you fellas. and lastly, it should be in D, not S? I should probably read the manual as I thought first that S stood for sport and manual shifting, but now it sounds more like slower driving??

It really depends if your car is tuned or not and what type of tune you have,some tunes really benefit the car in sport mode,for stock would keep it in D.
No sport mode knowledge here.
Rich
S for slower, haha. My son loves R/T for readily taken

IF you had a unleashed tune you would know the benefits datalogging and achieve the full benefits in s-mode,lol ;)
I may have to get this tuner for myself then, I read some good things about it. Well, I'll get to know this car as it's going to be my winter car.
do we benefit from running 93 in this car? I'll have to look into that ethanol mixture as well. what psi do you run in the tires?

IF your seeking full potential from your vehicle tuned or not and have 93 in your area then thats the way to go,tire psi 32-f-34-r,track 22-f-24r,hope this helps and good luck.

That's some low pressure. I went 28 front and 29 rear tonight at the track. I should have went a liitle lower because I was spinning a bit with a nice chirp into 2nd. It seemed like a grippy spin if that makes sense. Only made 4 passes and was content for the night, so no adjustments made.

Shonuup what brand plugs are you running?
There is a 93 in my area, next time I fill up it'll be 93. I think I had my questions answered, but I keep thinking I am forgetting something though.
Sp534 Motorcraft .030 gap
93 is a must for these cars IMO. Any less you run a risk of pre-detonation. I just started adding 2 gallons of e/85 to counter the winter blend fuel also. Great results so far. From 87 to 93 octane is like 10 hp stock.
Rich
So 2 gallons of e85 with 17 gallons of 93 octane, correct? What percentage mixture does that give you? I don't know much about e85, would that be considered as what they call it from factory, e10 or e15?
http://www.intercepteft.com/calc.html (http://www.intercepteft.com/calc.html)
Good way to find out.
The exact mix I'm unsure of right now because I haven't found out who BP buys their e/85 from and it may take a slight hit in the winter fuel mixing also. Assuming it's 16-18% right now. All I can say is my knock readings at WOT went from something, to not registering any knock at all through 4 quarter mile runs yesterday.
Rich
You guys are awesome, thanks for the help! I will do some research on e85, and start adding it to the tank.

If not monitoring your fuel rail pressure and AFR I would not exceed 2 gallons a tank, maybe 3. But a scantool combined with something to monitor on would be highly recommended in this area as all cars run slightly different.
Rich
Would shifting from D to S and back while driving be okay? Just curious on this one. Will it damage the transmission?
No, you'll hardly notice a difference.
Yup, no problems...car is really smart, almost to smart.
Rich
Awesome, thanks guys. I tried it today, and I can feel a slight change when I do it.
I ended up hooking my phone to the obd and pulled the torque app. The boost at idle was around -10, once I got on it a bit, hit like 9.7. So I was just curious, what psi are we running on these? What other important parameters should I add on my screen to watch for, like wide and and so forth? And what should be the normal readings? I have the free version of torque app, so I'm not sure what im missing yet.
Thread labeled torque PID'S take 2 is the mother load of info on this. Knock is my main reason for monitoring although that is changing now that I'm mixing fuel.
You need the pro version to add custom PID'S I think. Knock is a custom PID.
Rich
Turbos are rated for 14.7 psi. Torque is off on this gauge slightly.
Rich
And, before Rich asks for it, here is the link for the thread he referenced for custom Torque PIDs:

How much and in what way do you feel Torque is off on the boost? Just curious.

With Dave's dyno pulls he was saying mid 13's for boost and running basically the same tune. Getting spikes in the 16 range leeds me to believe torque is a bit off. A good measuring tool though to compare to your own readings to detect a possible boost leak.

Maybe the dyno gauge was averaging or filtering to eliminate the not very important spike. With Torque we are left with a pointer spotlighting a spike.
Good point. Torque monitors based on barometric pressure I think. And it varies with altitude if I'm correct. This may be another reason we see different readings across the board.
