Awesome trap speed!

In the summer time in vegas. doubt it.
Also..could you have done as many runs as he did without swapping out bottles or refilling it? We already know you couldn't.
BTW, my car is going to be model'd after Jeremy's..so its going to be fun too....bigger turbo, cam and headers from a different company, are the only difference.

j/kVegas is a tough track due to weather. In winter i'll pick up 4-5 mph, it's that big of a difference for a turbo car here!
If I ever go auto my times will plummit to the 10 sec range, but thats not in the budget for a long time.
DarkblueTA's car is gonna be fun. We're gonna boost the hell out of that thing, and it has a 12 bolt. It will trap 130 if the heads stay on.

Zombie when you rolled the 507 hp did you have the meth pumping and what was teh temp at that time. I just dynoed my car in 95* weather yesterday and made 100 less hp the i did when it was 60* weather. Also the relative humidity was 100% yesterday. So if you did yours on a bad day i wouldnt doubt the car could go 10.5 in 50* weather. GJ on the times man.

This is from a full bolt on 04 cobra on a 100 shot 11.056 @ 124.55 [1.629 60'] in winter.
Vegas is rough.
My dyno was done on a 90+ degree day. Was using denatured alky at the time. 50/50 with water. As for the 10.5, thats not gonna happen.

Verdad Gallardo The numbers also depend on whether your using meth or not. It can be 100 outside, but with Meth, if the IAT's are cool, then the motor doesn't care what the temp is outside.

I have to double check the logs, but I believe I was seeing 75 degree IAT's last night on passes. 
This is a related question that may help me understand his ET's. Since he has meth the temperature doesnt matter from what yall say. Now since he is at higher altitude level that makes the air alot thinner. SO if that is the case cant he jsut up the boost safely? Cause from what i understand power, not psi, is what breaks a engine so long as there is a good tune. IE if i am pushing 10 psi and only making 400 hp cause of atmospherical conditions then i really aint putting the amount of strain on the engine as if it wher ein perfect weather conditions and making 530 hp at 10 psi. So in the **** conditions i bump the psi till i get to the hp that i am looking for and if a nice day comnes along i have to step[ the boost down so as not to make 650 horse. I am basing this all off having meth injection. food for thought

You guys need to rememeber altitude effects turbo cars very little. The wastegate will shut until X amount of boost is reached. No matter whether its sea level or 5500FT. Now what will effect it some in the thinner air is, more compressor RPM is needed so the efficiency drops a little due to the hotter incoming air temp.
most turbo cars pick up 4-5 mph by running at a better track vs vegas. You can say altitude doesn't affect a turbo car as much, but it still affects it. The vegas temps are what really get us though. Next month we will have daytime temps over 110, upto 120 and night time temps that never drop below 90.
The Las Vegas track is slower than most tracks.
I believe the DA last night was 4600 ft. I always have to explain that vegas is a slower track to everyone even though they never believe me, even for turbo cars.
My dyno was 507 rwhp, my uncorrected numbers were 468! Most places have to correct down to SAE, not up to SAE. Vegas is murder for a FI car.

The turbo diesel guys will pooh-pooh the difference but us gas folks need oxygen for power, not just the extra volume of air. Higher altitude = less oxygen, thus the corection factor. The heat is just as bad.
Find out the SAE correction factor for the N/A folks and use half that for F/I.
This from a few nights on Google, search "turbo altitude" for more info.
John you should be on 93 and meth. I have never run race gas and you have much lower compression than me. Once I figure out what a/f she likes, I am going to see of I can go up on the timing.
