Horrible horrible!

Boost was as normal..8.5-9psi. I think I actually saw the needle shoot past 9 a couple of times.. It definitely wasn't reading below normal. I felt like it just wasn't pulling hard as usual on fourth gear after 80mph.

video of one of the runs :

DA was probably less than 1k feet as this track is pretty much sea level. Im not sure about the gas but that was a concern. I used 98 (UK) which is equivalent to 94 US. I always use this gas and not only for the track It may be the gas as this is the logical explanation. Once I flip it into 4th..its like nope...im not gonna go any faster and it crawls to triple digits. Only mod is corsa touring mufflers. Below are my times from Idaho in 6000ft+ DA and first time out.

60ft: 2.6 (first time out :ill
1/8: 9.127
MPH: 88.05
1000': 11.511
1/4: 13.510
MPH:113.46

MPH: 113.46

So yes. Something must be wrong because it seems the car might be pulling timing. Again I cleaned the MAF sensor on the spot. Car was shipped and parked for 60 days straight. Do you think spark plugs have anything to do with it? I also did an oil change so that's good to go.

I did the conversions and with DA it was 250ft altitude.

Heat soak definitely plays a factor..But considering I came from a hotter place and did much better? hmmmm. I was told that our ecu's arent programmed to run at sea level and that the car still may think its up at altitude. Then again i spoke to some guys in the area who are running bad times just as me... There was a 2011 GT500 running 13s too. Weird.

Yes, red-line all the way without hitting the limiter and some runs were done with no lift as well. I always cross in fourth gear.

Yea there was some decent head wind and from what I heard this track is actually uphill and not an illusion. Many American guys have said they run slower here than back home as well. Some guys told me the humidity and my supercharger don't get along. Dont really have much examples as all of the other cars there were modified but i lined up against a brand new 335 and he ran 14s. I also heard that one of the guys from here in a 2011 GT500 runs the same time I did. Another friend running his built Twin Turbo Charger SRT8 ran his fastest time [email protected] So mayyyybe im just freaking out a little here.

I agree, maybe ill hit up a different track some other time to see the difference. Also, the passenger helped me run [email protected] so yes it lowered my trap speed from 108-109.

hahah.. i dont know what it is but i can never manage anything below 2.1. Its actually pretty complicated
