Also, based on this logic, why even run races. You could just look at engine configuration and altitude and then bust out the calculators and figure out the winner without even cranking the engine.

bravo,well put.

this reminds me of pinks, how many car lengths you want? theres not a track on earth that would really be at sea level, right? unless your in a boat.so how come only certian tracks get the correction? plain and simple,no matter how much you want to argue, you run what you run, you can correct it all day long but with out a time slip NO ONE IS GOING TO GIVE A SH$T!!!!

well there is close to 5000' DA difference between the two tracks, but since I'm running a blower, DA affects me much less than it will an NA car

So far there hasn't been a non-dr Z06 running anything faster than mid twelves here, just because of the air.

But my car never ran an 10.7, so I can't claim that it has, or it WOULD even.

I have no idea what it would run in phoenix. Some cars run close to a full second faster up in phoenix, even if they are turbo/blower, some run slower.

I can't just magically claim "oh, this is what my car WOULD run"

All I can say is that my car is CAPABLE of running said corrected time at sea level, given the exact same run.

No one will ever duplicate a run, except for the guys running in Stock, Super Stock, and Comp, why do you think those are the only ones they accept corrected times for?

Those guys are so consistant, that they probably CAN go to a lower track, and run the corrected time, because everything else about their run stays the same.

When the driving changes each and every run, at the very least to some degree, then you can't include corrected times, because it would take alot to duplicate the same run, in the same car, in the same conditions, at a lower track

what? your driving changes based on your run? you suck, gtfo.

alright AZ.. have you read my posts on the DA correction factors based on PSI from blower/turbo? you should be able to figure out your correction based off of those if you haven't already.

a lot of you are claiming that because you are runnign more power you wouldn't get the traction to run the time you claimed.. OKAY.. how many 100hp Civics have you seen (or you can put a rwd car instead) have run a 1.7 60ft at a 100ft altitude? There is more in play there than the hp/traction time

same tires, new gears.. i got .4 better on the 60ft and better DA... 4200ft DA owith 2.0 60ft stock tires vs 6500ft DA and a 2.4 60ft.. I SHOULD BE SPINNING EVERYWHERAEREERE ...

really.. I see a bunch of people at lower altitudes trying to make excuses on how they dont suck at driving.. just because some people at a higher altitude (and not all people. riptide i think is a hell of a driver.. and i just have easy mod auto) are baeting their times.. but only through DA correction (or altitude)

I will take a bet... if I get the time off work i am willing to take a trip to a reasonable altitude track(500ft or less), you pay for it.. if i dont run atleast a 12.9@107mph I will pay you 2x your money back.. im certain i will drive that well... even though my best was a 13.5@102mph on a 4200ft DA.. or 3600ft altitude track..

You trying to say I suck at driving?


Seriously, DA plays a big role, but it isn't the only thing. Example, Track prep maybe awesome at your track, whereas I can promise you, it SUCKS where I run. You need to get yourself to a lower track and put this thing to rest man.

ORLY? Because I see guys at higher altitudes trying to make up for it by talking about corrected times. So are you trying to say I am a poor driver? That is just laughable. Build a car that "should" run better than an 11.9 and then maybe you can compare your driving to mine. I can tell you this, pulling mid to low 1.5 60's on a 275 drag radial aint easy and it took quite a bit of effort to dial in the car and get to leave on tracks that constantly were changing. Like I tried saying before. Correction was started for guys in Super Stock, Stock Elim, and Super Comp. as a way for them to dial in the cars and compare themselves to other cars at other tracks on other days. If you want to use it as ball park, rough figure fine, but it seems there are a few of you guys that seem to bring it up over and over as a way to justify something. As far as the NHRA being the "an authority" maybe, but only if you happen to run at an NHRA sanctioned track. All they are is a sanctioning body that set forth rules and classes. What if I run IHRA? NMRA, IMSM, or any other of a dozen series out there? True that I have to abide by the host tracks tech rules (be they IHRA or NHRA) but that is where the "authority" of said sanctioning body ends.
