1/4 mile results with my 100 octane map

TurboQueef · 06-16-2006, 07:22 PM

Just got back from the track... overall I am marginally satisfied with the results. I did make some improvements but not as much as I hoped for... here are key points:

My best pass before tonight was 12.98 @ just over 104mph. The temp was 52 degrees during this run
Tonight I ran 12.98 ET with MPH of 105.35. The temp was a blistering 88 degrees during this run.
After the 12.98 run, I added a bit more timing (5500 to 6K) and then made my best MPH run to date: 106.04. The ET was only 13.08 due to a for **** 60' time of 1.913

The bottom line is my 100 octane tune seems to be perfected but my performance is the same as my friend overdose gets with 93 octane. One of the factors that seems to be limiting is my downpipe. I am running the COB CAT version and I think it is holding me back (my MAF voltages are still lower than overdoes gets with a cat free DP).

I have attached the datalog from my 12.98 and 106+ pass along with the map I used. If anyone has comments, please post a reply

I would say work on the driving skills and shifting, at that trap speed I was able to run a 12.8 pretty easily not to mention the possibility to break the 12.8' margins easily in the 1/4 mile. Come out to AR Fab tomorrow, Doug it tuning are cars there in Winchester, it shioud be an awesome day

the trap is kinda low, but the 1.7's are nice

hey i know this is alittle off topic, but i have the cobb ap Protuned and i ran a 13.01 @105. I have equal length headers, i notice that you have the Gt spec headers. Im going to be gettin those soon, how do you like them and are they unequal?
