Not sure where you got your info, but just searching on Nadaguides.com, it shows the Evo 9 GSR at 3274lb and the Evo X GSR at 3517lb...a difference of 243lb. No where near a 4-500lb difference. And I know that is a significant amount, but with the X making just a bit more power and 1st gear a little lower, that should help keep it close to a 9 with both in stock form. I wouldn't expect it to run the same time, but within a couple tenths of a second. First and only time I took my 9 to the track bone stock, I had no idea about the stationary rev limiter. I launched it at 3500rpm, run a 1.92 60' and still ran 13.3@103.5 and it was 80-85 degrees. I'm just saying I think the car should be running better times than it is...or so it seems.

Without knowing your 60ft is hard to tell. Its also hard to compare one car to another without giving account for altitude, humidity, and numerous other factors.

Maybe i missed it but do you have your 1/8th mph/et?

from the reading i've been reading stocks should be running around 100mph traps..I will take it to the track again today so I can get you guys more info on the run the time slips should be showing my 60's..I just feeling like i'm loosing power somewhere and it maybe my driving but I don't think my driving is that bad at all..I will post my time slips tonight.

went to the track today..here's my slip right next to a 07-08 wrx sti 70degree weather.

I know my 60 isn't great and this is the best of 5 passes..I still feel like im loosing power around 3rd and 4th gear..what do you guys think? just bad driving? hehe

You may be losing a little topend, but I wouldn't think very much. Try shifting around low to mid 6k...like around 6200. On a stock map, thats about where peak power is...then ride out 4th gear through the traps.

People are saying the X will go mid 13s with a good run. You cut your 60' time down to low 1.7s and you'll be running 13.60-13.70 without changing anything else.

i'll give that a try next time..I was shifting high because someone on the forum told me to shift higher..hehehe.

this maybe a stupid question but should i be pumping 91 octane on my evo x or 83?

I'm hoping you meant 91 or 93. Use 93 if available. Even if the car is factory tuned on 91, it will should still make a little more power on 93 without being retuned. 93 octane is way better gas than 91.

Mine was X 440 lbs heavier than my old GSR on the same scale and I had less fuel in my X when I weighed.

Either way, you are a half second slow compared to where you should be. You are 315lbs...that makes a bit of difference but not a half second and 4mph. It could be the track, your altitude, etc. but going off what the stock STI ran, you should be right there with him. You 60 is OK at best. Get it into the 1.8s and you should see your 13.9...and that might be the best you get with that car and you weighing 315. I'm at 270 so I feel you on that!!
