Untuned 426 Hemi Runs 1.2 Seconds Faster....11s to come?

[Redfox0099]

I am posting this cause I am happy with my results so far.....please read on to learn more


Stock my car ran a 13.6 something at 103 MPH in Ennis, Texas (I have it written in my spreadsheet but I will provide my timeslip from SE Shindig which was roughly the same times if needed).

This last Friday night my Magnum ran 12.417 at 111.44 MPH


DA= 2130
Altitude: 510 Ft
Air Temp: 78*
Altimeter: 30 in.
Humidity: 88%



This was done on Street Tires, non stripped interior, and a race weight of 4765 pounds, an A/F that goes off the chart for being too rich (new smaller injectors already ordered), and only 15 degrees of timing in Drive...

MEANING soon, very very soon the 11's will be mine...all mine


How does my DA compair to yalls where you are? how much does DA effect your times?


Dallas300C was on hand for the racing and took some video...will post it tomorrow.

nice............i love the mph

Nice Redfox

According to an NHRA Calculator I found here :
http://www.smokemup.com/auto_math/nh..._factors.php#1


My times Are:

12.417 E/T at 2130 Elevation (DA) Corrected to 12.115 E/T at seal level

and 111.44 MPH and corrected to 114.28 MPH


Is that correct?

First, congrats on the runs! The car seems to be doing better every day! Just a little more "tune" and you'll be where you want to be. Also... nice runs at the Texas Mile! Too bad there wasn't a tail wind!

Now...... many will hate me for this..... but leave the corrected times at the door!
While I understand and appreciate the need for corrected times for comparision purposes...... it is ALL theory......a corrected time is something that COULD have happened..... a timeslip shows what REALLY happened.....
Regardless of where you are, temperature, or humidity...... the clock ticks the same everywhere! Post the DA if you wish..... but also post the timeslip (as you have done)....

Again.. congrats.... and sorry to litter your thread with my opinion.... but I feel it needs to be said again...... Post the slips!

FWIW,

NO I agree with you completely BO, you KNOW I DO (Per previous discussions)...

The reason I asked was guys up North where the air is cold and such see our Texas times and think they are crap....I was just trying to make a point but I will do it in person at the SE Shindig

That's amazing especially considering how heavy these cars are. Pretty soon you will need a roll cage.

Posted in the wrong thread.

Let me start by offering congratulations to Hemi31, great times, You will be in the 11s with a little more work, and it's really close if you can get to run at sea level.

Thanks, but I am not Hemi31

Great, now I feel like a loser

Opps, wrong thread. That's what can happen opening two windows at the same time.

Ok, lets start again here. Congratulations Redfox 0099. Awesome times. You've got competition to get to the 11s. May the "best" man win.

Now I have to repeat myself but I think i"ve got it right this time. I don't hate you, but I have a little different take on the subject. My times have matched what would be predicted using the altitude factor table. I've raced at 2700', 1200' and at sea level. What I'm not saying is using the DA and pluging that into the table. Never worked for me to predict times. Using the actual altitude does. If I could have the real altitude and temperature I would have a good feel for the performance achieved.

BTW, dyno numbers are corrected numbers.

I agree with both of you. Whole other outcome when you line them up on the same track.

I myself prefer knowing DA, not to do the conversions, but to give me a perspective on what other guys are doing. The ET's are relative. When I hear someone going 12.80 with a DA of -1800 and we have the same basic cars at our tracks with a DA of 2750 running a 13.30, I know on the same track the 13.30 car would probably win.

IMHO I would like to see DA listed with our ET timeships. Not the conversion of ET and MPH. Just to make it relative for those that want to know. So when I start going to other parts of the country with my car, I will have some idea of what I should expect to run.

Very nice times by the way Nathan. You've got a monster there and some more tuning and some non breakable parts you will acheive your goals.

Somewhat. They can also be manipulated some too.

We need a huge LX Drag race event somewhere. We would then all have a leveled playing field.

Isnt that the plan at the Shindig?
