You need to work on a bunch of stuff, were you 100% floored in those two passes in those slips?

Definately need to learn alot , thanks for any input you can add.


Not floored off the line but once it hit about 3500 rpm and was already spinning , figured what the heck lets go for it
left it to the floor for the rest of the run.

I'd post your your best slip, full list of mods, rear tire psi, date/time/name of track run at, and your shift points.

I want to get a Whipple myself and I'd hope first time out I'd run 120mph.

From your signature it obvious that you are an experienced 1/4 miler.
I'm sure the 1st time you drove "MY" car at the track would be a remarkable improvement.
Here is the info you suggested
Time slip Above 8-31-2012 9:13
60 ft 2.099
1/8th 8.477
1000ft 10.89 @ 101.42
1320ft 12.91 @ 110.95

DA from the track 3960
Temp 88
Humidity 46%

Intake temp was heat soaked pretty bad.
Start of run 56C= 132 F
End of Run 68C= 154F

Shift points from Data Log its SCT show Metric Speeds
1-2 5350 --- 52 kph
2-3 5250 spinning erratic rpm fighting for gripspeed 89 max 81 after shift
3-4 6068 103 KPH
4-5 6203 165 KPH thru the lights but held on for one last shift

To be fair I never looked at all this info till you asked for it... just forwarded to the Tuner.
Kind of and Eye opener as far at the lousy shift points in the 1st 2 gears.
Even worse was teh Air intake Temps.

The Car :
2012 L99 Automatic
Stock Gears 3.27
Stock Tires 34 LBS
PFadt Subframe Bushings
PFadt Trailing Arms Toe Rods / Bushings
RotoFab Cold Air intake
WaterBottle Still in place--no Scoop
Whipple Charger 3.875 Pulley 9 LBS Boost Max
JBA 1 7/8 Ceramaic Headers HighFlow Cats
Stock Exhaust Back of Cats
91 Octane Fuel less than 1/4 Tank

Without good tires don't expect any decent times. That's the most important part but for some reason that's where everyone gets short arms.

You weren't as heat soaked as you think. Could it be better, yes, but that's not crippling you. I finish a pass with iat's in the 170's.

Your shifts point are awful. Why are they set so low. From the info you posted that's the obvious problem. Get that taken care off and you'll see a difference.

Driver error is all I can say.

Looking more into the SCT Data Logs , I've read before that the Throttle Body does not go to 100% reading even at WOT, but what is the MAX that should be showing if I'm truely on the floor ?

I think it's 83% for wot.

Also I'd like to add you should have more gas in the tank. Less then a 1/4 is not good

[nyny69]

It also might be short shifting because of the spin

Had originally planned to buy some unleaded Race fuel...but really needed to get some WOT runs logged on the 91 Fuel 1st.

I thought it was something in the 80's
Guess i need to hook up the Laptop and investigate .
My max readings were only 72.6 Y .

Take your mat out and make sure you push with the ball of your foot.

I've been down that road. Your not stepping on the pedal all the way.

I run a can of torco everytime I go to track

Heres a funny one for you.

Just went out to look in the car to make sure the mat wasn't causing interference.

There are 2 mats... the Factory and the Upgraded/Deluxe on top.
The deluxe one had pushed forward not allowing a full travel on the throttle.

Actually kinda nice .

Now I know the car has alot more to offer.

Just get the driver to pull his head out.

It is also 88% for me now. It used to be 83% until Ted changed things recently.
