Stock Ty runs 12.60??

WTF.. did I miss the LSD train on it's way through? Someone tell me how a stock Typhoon, in Colorado of all places, runs as 12.60? Maybe he just picked a random number that was faster than the 13.3's that Lightnings run, since Lightnings are "not even as fast as the Typhoon "

Halfway down the page, with a picture of his Ty.

Plenty of this going on :drinking: :drinking: ::hang::

that is rs25.com
he posts here and is respected.
some sytys are factory freaks, some with a good stock tune will run great times.
with some tuning you can get a basically stock ty pretty fast.
12.6 probably has altitude correction included.

Truckless. For now.
I think it's acutally closer to 13.6 like Will's Ty here in CO, and 12.6 is the adjusted number for sea level, according to the NHRA guidelines.

That is a stock as a rock Ty.

I'd want to see a timeslip.

If you want go by
"I was oh so close to someone else on the street that runs a 12.6"
I'm not buying it.

I was oh so close to a AWD turbo eclipse on the streets but when we went to the track he ran 11s and I ran a 13.

Well put. I've seen Will's timeslip, but haven't seen one for James, don't know if he's been to the track or not. You definitely can't get more stock than his Ty, that's for sure.

WOW, i am suprised you guys don't think a stock turbo ty can run 12.6's...that is amazing as I have seem severl do it. Like I said, if he is using alt. adjustment in his calculation, what is so hard to believe about this???

Guess I'm just not used to people using altitude adjustment. I see it the same as "Well, I don't know what I run, but this other truck with the same mods runs 13.5, so I must run a 13.5". I was just curious how the number came about. I'd sell the L if I ever saw a stock Ty run a 12.60 in front of me.

brian, take your L up to his elevation and you'll seee that its a second slower. If its NA, it'll probably be affected even more. Not starting problems, but guys up in Denver have to get some sorta of break vs. guys like me located in seattle. I think alt. adjustment is fair, if there is a NHRA standard.

The NHRA has special calculations, that they've tested and retested to adjust altitude runs. It's just like a handicap in golf. Makes the playing field equal. They have very strict guidelines, and you have to call them, etc. to have an official, verified, adjusted timeslip. Talk to Will_in_Denver about it.

This is correct. I suppose I should have mentioned that, my bad, I was just keeping it "sea level" for the Subaru guys... :eek:

Will's Ty and mine are millimeter to millimter the same speed. And, yes, Will has a timeslip which is NHRA certified and all that. But when Will and I race, we're dead even. The entire time... It's kinda freaky - it felt like we were chained together or something! :)

I may be wrong, but isn't a turbo capable of sustaining the same boost whether at sea level or altitude? If that is the case the same psi at sea level and the same psi at altitude will make the same hp. Now, I know with blowers it's different because you depend on a fixed pulley so you are limited. For instance I run 6psi at 3300', but at sea level I would run 7.5 psi. But with a turbo, isn't your psi regulated by the wastegate which is dependently on psi?
Just a thought.

These trucks are cursed
i think its possible...
at the palmdale,ca track i run 14.0x, which is at something like 3500ft, and in fontana, i run 13.4x which is closer to sea level. so at "mile high" altitudes i can see maybe a .8-1.0 correction.

Well sure the PSI is the same irregardless of the altitude, but you have to remember one thing - there is less oxygen at higher altitudes.

I don't know exactly how much oxygen there is in the air in general, but let's assume at sea level there are 100 parts of O2 for every PSI then at 10 PSI you've got 1,000 parts of O2. However, at 6,000 feet above sea level, let's pretend there are only 80 parts of O2 for every PSI, then that same 10 PSI of turbocharged air only has 800 units of O2.

And of course, we all know oxygen is what creates combustion. More oxygen = more power. So, PSI doesn't matter, it's what's being inhaled (or lack thereof) that makes the difference.

What sucks is that a 13 second run up here would be a 12 second run at sea level, which I have not actually experienced in my Ty. I would love to actually run the 12, but for now I just have to use statistics. :(

One day I'll move back to CA and have some real fun!

This is how i understand it to...flat out, there are less air molecules at higher alltitudes. Hence, less air molecules per psi, regarless if you are running 10psi or 40psi.

Hmm, that makes sense. But, isn't the ratio of O2 to other gasses (nitrogen, CO2, CO3, etc) the same at any elevation. If not, your argument makes sense. OTOH, if it is the same ratio, and PSI is absolute and not relative, then 15psi of air compressed from 3' or 6000' would contain the same molecular ratio of gasses.
Hmm, confused myself now, LOL.

As I recall, it's due to gravity - air at higher altitudes simply has less air - because there is less gravity to hold the air molecules. 02 is light, but like anything else there are more concentrations at lower altitudes. Think about the reverse: If you hold a soccerball under 10 feet of water at the ocean, it's not big deal. But at 10,000 feet the pressure is so great that prettu much nothing can survive - the ball would implode - extreme purpose-built subs with massive reinforcement survive but that's about it. Oh, plus some freak glow-in-the-dark fish! :) Hence why fighter pilots have to wear oxygen masks at extreme altitudes. There simply is not enough air up there to support breathing. Jet engines are fascinating in design as well since they often have oxygenated fuel to work - I bet the space shuttle is like that. The fuel already has 02 in it. (I'm guessing.)

And yes, 15 PSI would comparitively have more oxygen. However, since my Ty runs a good 15 pounds of boost already, I'd have to turn the boost up to get more O2 in the engine. Yet I doubt the stock internals could handle 20 PSI (nor could the MAP sensor or ECU compensate for it) so it wouldn't really make a difference to me. Well, without damaging things. :eek:

the problem with the correction factor is that if you took the vehicle down to sea level it wouldn't run the number.....in other words, a stock ty can't run a 12.6. The correction factor is much more accurate on N/A vehicles although I can't explain the physics behind it. Common knowledge is that altitude has less impact on turbo vehicles as opposed to N/A vehicles.
