Which is why I said he never saw 8000' DA at ground level.

 

Beautiful. Can you please explain how to factor in humidity when calculating density altitude. Thank you. Have a nice day.

 

Question: You're at a party. You look around. How can you tell if anyone in the room is a pilot?

Answer: Don't worry, they'll tell you.

(Sometimes we even tell you in every single post we make on the Internet.)

 

 

You guys are crazy. My "home" track is MIR. I live 5 minutes from Capitol Raceway in Crofton MD but drive over an hour to MIR because it yields better results. There are certain tracks that you will get better times at from many different variables: track prep,ft. at sea level, humidity, Barometric pressure, air temp, sunny/cloudy. These ARE the reasons why all the best times come from a handful of tracks on the EAST COAST. It is the combination of all of these things and most parts of the country won't get accumiliation of the ideal conditions that we do here(east coast). Anyone that knows dragracing knows that there are very capable drivers all over the country that will never approach any of the top fastlist times because their conditions will never ALL come together like they do here.
This is all common knowledge and if your suffering from sour grapes because you live in CO, AZ, or CA ect.. and will never see those top times then come over here, show what you got and put down some impressive #'s. If not tough s#!t, shut up.
On the other hand if you race at any of these "ideal" tracks your kidding yourself if you think your that much better of a driver than everyone else who tracks their car regularly in other places.
Its no secret Dennis50nj set his sub 11 sec. mark when all of the factors came together to make for ideal conditions(great driving, track prep, weather). The same goes for Ranger,Jamie Furman, and whomever else you want to throw in the mix. There are many really good drivers here but don't think your s#!t don't stink because you race where you race.
I'll never understand the argument here because if you know dragracing its pretty obvious what it takes to make a great pass.

 

Are you saying dew point and relative humidity aren't related???

I am not hurt by the science and my ego is not fragile - I do not have any dog in this fight. I read the thread for the information regarding DA and, following same, realized that you must be the most self important individual on this forum. I was just poking fun at you because you think you have the biggest brain on this forum. Might it be you that has the big, fragile ego? As point in fact, you are pompous enough to assume that I agreed with you. I respectfully suggest that you re-read my prior post, I disagreed with you but thanked you for a coherent, well thought out, detailed explanation of DA that you placed in a cocoon of crap. Go ahead, re-read my post. I conceeded nothing to you and, instead, suggested and continue to suggest that, at our power levels and set-ups, it is more the driver than the 20 additional rwhp. I speak from experience - I had a 10 second Supra Turbo (MKIII, not MKIV) from 1989 - 1994. I have had equally fast cars throughout the years and, additionally, have been frequently asked by friends and strangers to make passes in their respective cars. I am no stranger to the track/racing - at least 1000 passes since 1986 - not to mention all the stupid street racing I did when I was much younger and reckless. I have beaten "faster" cars merely because I could drive right around them.

As to my post, get over yourself. You would have found the "Uranus" comment hilarious if you were not the butt of the joke (pun intended). I'll bet you felt really good about yourself when you thumped your chest and insinuated that those that can't type and/or refuse to proofread are less intelligent than you. Someone had to point out that you were acting like a tool. I just happened to be the a$$hole to do it.

I pointed out to you that correction and DA are not the "end all, be all" of good 1/4 mile times. You have yet to dispute my assertions that it is the driver more than the rwhp (increased/decreased by DA) - in fact, you failed to address the same. And what about the transitive property? What about all of the other non DA variables? Should we ignore these because you say so? I suggest that it is all of these variables that comprise a pass down the 1320. Whether your 1320 experience is any good depends upon how well you use the hpr to pedal the car down the track.

I am willing to bet that someone with less hpr could go faster than Dennis at a track with a higher DA if the car was more purposebuilt for the 1/4. Dennis has still more room for improvement (within the external mods criteria and without adding 1 more rwhp) and does not need to rely on DA for an improvement in time if he wants to take this 1/4 quest any further.

Thanks for your explanation of DA. If you wish to take it further, please feel free to PM me.

 

 

Yeah, what he said. And trust me, my $h!t stinks - everyone in the office tells me so.

 

I have posted enough information, factual information, to educate even the most stubborn that DA is beyond all doubt a major player at any place you race. No other single factor can have the most effect on a cars performance without changing your combination, period. You might as well try and convince me gravity is of little effect too on why my vette hasn't just floated away, it's that real.

Ah gee, AirBusPilot, yer jus jelus u elitist over edyacated smert azz. Yeah, sure I am. lol I know most that have posted in this thread have seriously fast cars no matter where they run.

And be sure and get back to me with the location of that 8000' DA day in NJ. I want a location and date please, otherwise you're just b.s.'n.

 

Don't worry, they say the same thing about my profession - attorney. And I usually resemble that remark. Difference is that I get alot of work out of it and Airbus just gets to stroke his ego.

 

Whoa there big fella. I didn't mean to pi$$ all over your online calculator parade. I just asked how you calculate the effects of humidity on density altitude. I understand how moisture displaces oxygen, it's just that us pilots have never been taught that math. We consider pressure, temperature and mean sea level when we calculate density altitude. I just went back to both of my most prized textbooks and looked for some way to factor in humidity when calculating density altitude and neither Stick & Rudder, nor Aerodynamics for Naval Aviators mention it (although there is a good section on transonic flows and the compressible nature of air that would be of interest to most Vararam customers, but I digress).

So ... how does one factor in humidity when calculating density altitude?




I suggest that he remove the door skins and carpet next, but that's just me.

 

Um ... what? You really should proof read a little better. It's makes you look less intelligent when you write things like this.

 

I don`t care who you are, thats funny!

 

I tried to tell him that yesterday...

 

i had egg salad for lunch and i thought the air was bad here !

 

Thats impossible! There is know such thing as bad air in Jersey!

 

See above responses in red.

 

My only response to your lack of understanding is to ask what airline you work for, so I know which one to avoid. Of course, that assumes you're an aircraft pilot rather than a riverboat pilot or any other profession with the pilot job description.
