First Time at The Drag Strip
Well, I went to my local 1/4 mile tonight. Took the IX out for the first time. There was a nice turn out, but not many imports, mostly older american cars.
Heres the info...
The place
Redding drag strip - Elevation 490'
Temps
8pm - 73*
11pm - 67*
Humidity
8pm - 44%
11pm - 57%
The car
06 IX GSR (bought feb. 06)
HKS panel filter
WORKS 3" TBE
Boost controlled by ECUFlash & stock boost solenoid
Runs 1-3 - 21/20 tapering to 17/16
Run 4 - 22/21 tapering to 17
Stationary Limiter set to 5750
1/4 tank of 91 Octane
Removed Spare & Tools (-37lbs.)
Installed Sub & Amp (+57lbs.)
-------------RUN1----RUN2----RUN3----RUN4
Reaction---0.85-----0.81-----0.60-----0.78
60ft---------2.32-----1.95-----1.97-----1.90
1/8----------9.05-----8.57-----8.52-----8.40
1/8 MPH--81.11---81.01----83.46---82.40
1/4--------13.80---13.33----13.21---13.16
1/4 MPH-103.93--104.39--103.08--102.16
When I upped the boost by 1psi, as noted above, the car seemed weaker (according to MPH), but it was my best E.T.
I already know my launch is pretty bad, so flame away.
EDIT- added slips, I am car 172.

Everybody has taper (with stock turbo & WGA), and anybody that says they don't is lying to themself. All my boost numbers are from MAP sensor logs.
Also, a couple post up, it says I tried to get some race gas but it didnt work out.
Sorry if I come off "WarrTalon style" (j/k Warr)
Anyways, I should be gettin a Jestr E-flash later this week

^ You'll notice that when you hit a quicker 60ft that your trap speed will go down a little bit, so thats normal.
The car is down on power though for a 9 with TBE. My 8 trapped higher stock, but it was on 93 so its not a direct comparison. Have you done a boost leak check yet? With those mods if you arent pulling timing you should be running 106-107 traps even with 91 oct.

I haven't done a boost leak test, but I have logged boost many times and there seems to be no leaks, but you never know, there probably is a leak or two..
but after reading thread bout 1/4 mile times of IXs in California, I'm some what pleased with the results.

i had about the same time as you...no tune, evo9 turbo, stock boost, full tbe, full weight...my 60ft times were 2.0 all day and the best run for the night was a 13.3@103.7mph, this was at famoso raceway...the weird thing though was that i had 2.2 60ft the first time and my trap was still the same 
--im pretty sure i have boost leaks...or i thinks so...i'll be testing it when i install my nisei licp

I disagree with the TBE comment. its gonna give you a better boost curve, better response, and more top end because of less restriction.
Logging boost will give you no indication if you have a boost leak, fyi.
The results are not bad at all, it just seems the car should have a little more in it.

What track did you go to?? Those times aren't that bad!! When I 1st started racing my evo_9 my 60' sucked!! But with practice and more track time my 60' where getting more better!!

Yeah, never rely on a boost log to determine if you have a leak or not. You will see the same boost numbers with a leak, but the turbo will be working harder to maintain that boost.
Car is very weak for such optimum conditions. However, it's almost impossible to run a 13.1 with only 102mph on a 1.90 60'. I can't imagine how in the world you did that unless the car was actually going a good bit faster most of the way down the track then started knocking up top due to the extra boost. This is not likely, though, considering how rich the stock tune is.
I know you're wanting to control boost electronically, but you'll eventually get an MBC when you get frustrated with the boost characteristics and get tired of going slow. you're right about the "no taper" comment, though. All these people keep saying, "With my MBC, I hit 21psi and it holds to redline!" All that tells me is they've never logged their boost with a MAP sensor.

Yeah, I'll probably do a boost leak test before I go back to the track

That's exactly what it felt like, some knock in 4th from the extra boost. Don't know if you have 91 or better in CO, but I can tell you 91 will knock on the rich stock fuel map, even from just a little extra boost. Hopefully the car will be dynoed soon, but dont know if I can dyno before and after the E-flash. I'll most likely dyno after the flash.
Also, I know the car seems weak, but if you look at other drag times posted by CA IX owners, my time is actully very, very good.
