TIME SLIP


Track Info @ approx time of time slip:
Track Elevation: 553 feet above sea level
Air Temperature: 72.3 degrees F
Barometric Pressure: 29.95 inches Hg
Relative Humidty: 71%
Density Altitude: 1757 feet
Relative Density: 94.96 %

My DA Adjustments:
Stock and Mildly Modified Naturally Aspirated Engines
13.407 @ 104.438 MPH

Completely stock or mildly modified ?? I don't get it.
Also the 13.407 is that a real time??? DA Adjustments mean it should be that???

Good job. You're working it. Like me.

This reminds me of the famous quote from president Teddy Roosevelt: The Man in the Arena
Quote:

It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better.

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.
Agreed? :tup:

I'll hopefully be able to get some 1/4 mile runs finally here in the next month or so.

Z eliminator 10-07-2012 06:48 PM

i kept ajusting the fuel curve with the Cobb aces port.
it started to rain before my last pass and i could not run the fuel curve that i made
best 60 ft 1.84
best 1/8 8.04
and a few 12.62 passes when i hit the rev limter at 8100
One was a great run and i hit it shifting from 3rd to 4th.
I data logged it it cost me 2.4th on a 12.62 pass.
Temp was 49 degress and 95 RH %
learned a lot about tire presures today i ran at 18to 17.0 lbs. to traction problems, will try to run higher preasure next time
Now for the BAD NEWS
all motor stock mustang 2013 5.0 ran 10.88's all day " all moter "
unbeilable !!!!!!!!

Also the 13.407 is that a real time??? DA Adjustments mean it should be that???

These are weather and altitude adjustments from DragTimes.com calculating what my actuals would be at optimal conditions. The stock/slightly modded header is from dragtimes.com. I'm completely stock.

As far as DA adjustments, there has to be a “Standard Reference” (SAE J2723) when determining the Rated HP of a given vehicle. And this is done by operating the vehicle in a “Standard Environmental Condition”.

Ideally, a Standard Environmental Condition (“Standard Day”), and would be:
1. Sea level
2. A barometer of 29.92” Hg.
3. An ambient air temperature of 59 degrees F (+15 C)
4. A relative humidity of 0%

This meteorlogical condition is the basis of determining rated SAE HP. It is also the standard condition for determining 1/4 mile acceleration performance.

Just because a track is at an elevation close to sea level, the Density Altitude (DA) of a given track may be real high due to a local environmental condition of low barometric pressure, high temperature and/or high humidity at the time … So, we can say that; Density Altitude (DA) is the actual altitude of the track adjusted for the barometric pressure and relative humidity at the time.

Then combine a high PA with a high ambient air temperature, and you get a very high Density Altitude (DA) … Density Altitude is the actual track altitude above sea level, adjusted for the barometric pressure, ambient air temperature and relative humidity.

And a high DA is what kills horsepower and results in high ETs and low trap speeds.

On the other hand, operating a vehicle on a track close to sea level, at very cold track temperature, a condition of high barometric pressure and very low humidity would result in faster 1/4 mile times than when operated at a Sea Level / Standard Day track, and would also not be an accurate measurment of the car’s rated HP.

Without a “standard condition reference”, there is no way to determine whether or not a certain modification has made an improvement or not in regard to power output … So, you need to make an adjustment in the ET and Trap Speed for the variation in Density Altitude on that given day and time.

andre12031948 10-10-2012 07:15 PM

You are doing 13's completely stock. Good job. With a few mods & a tune 370's can do 12's quiet easily. Have fun drag racing :tup:

FPenvy 10-11-2012 08:36 AM

i think i'm going saturday for a test and tune to hopefully beat my best time at a different track. i should have had my intakes by now but i guess their build date got delayed. oh well bright side i can see the difference in time based on different tracks with same mod (exhaust only) so i'm happy about that. i'll be sure to let you all know how it goes.

tranceformer 10-15-2012 06:43 PM

you're on the list! keep racing and get those ET's down!

I wasn't that pissed cause I had just run a (at the time) best ET of 12.89 the previous run.

I just kinda laughed at it. :icon17:

Back in the seventies I ran a 10.01"et on my dragbike. It took almost two years before I finally got the three-digit time card. That was hard to follow.

Oh well it's not that bad then. If 13.001 was the best you did though that day, then you'd probably be more pissed.

I went to the drag strip last Friday, but had no luck. Not sure what the problem was but I had like no traction at all. Didn't get even a single decent launch. Was getting wheel hop at first, then after lowering the tire pressure the wheels just kept spinning and spinning after at each launch. Tried shifting early to the next gear, but wheels were spinning all the way into 4th. Temps were in the 50s and my summer tires were pretty worn (2/32 or less tread left). Very frustrating day so I just left after like 5-6 horrible runs. Best I managed was 13.45 @ 108 even with the traction issues. That was my first run and things just seemed to get worse and worse further into the night.

I've tried it before and it's actually slower that way. Not sure if it's just me, but I feel like the car gets a little more aggressive when you put it in manual mode. Though that's probably because I put it in manual mode whenever I want to do some spirited driving.

andre12031948 10-28-2012 11:09 AM

The drag section here is kind of slow so
 
I changed my rear end from a 3:90 to 4:08. I have 100% stock suspension, but I did a common sense adjustment/change that may help me get 1.60's 60foot times. As soon as the weather clears, (tired of the rains & humidity) I will try to go under my 12.504 record run. I'll be at Atco & or Raceway Park. Company welcome, so would witnesses that can verify a mostly stock Z.....:)

SharpByCoop 10-29-2012 07:08 AM

Say when. I'm on the verge, too. TIming has to be right.

Good luck for you. 1.6 60" times are envious, indeed. :)

Sure thing, as soon as cool calm weather comes. If it comes:confused:
I need 1.60 times because I'm UNDER 300whp. Maybe 290? Stock intake, test pipes with stock exhaust minus muffler. Muffler was lost to the flood:)
With cooler air, my new 4:08 gears & a slight adjustment to my stock suspension might help me achieve my goal. Under 12.5 or die.:icon14:

Great news GTM has shipped my stage 4 fully built 7 AT with his latist VB with all the mods. With my Pro torque converter this should be a killer comination.
the only problem is will the track be open in the 2nd week of Nov.
Im going this Sat weather permiting high of 46 degrees . and sunny.
still N/A with bolt ons.

New Personal Best: 13.37 @104.76
http://i50.tinypic.com/64jwap.jpg

Running on Bridgestone RE-11 305/30/19

My first three runs where 3.38, 3.37 and 3.38. Running 25psi Those where the best, after that I tried adjusting by lowering tire pressure to see if I could get sub .2 60' times, but they just got worse and I forgot to bring the air pump. Went a couple of times at 22psi, and my 60' where 2.3/2.4 had horrible wheel hop and worst times (13.6/13.8), seems these tires like more air.

Track temperature was around 75F, I'm still not pleased with my trapping speed, fully bolted and tuned, removed (Spare tire, jack, etc..)

There was one run where i trapped higher 13.38@ 105.31, 60' 2.16.
what you guys think??

I'm running 13 flat on Michelin piolt SS tires at stock 35 psi and only have an exhaust. I'm mad I couldn't Breakin to the 12s when I went last time too had all the tracks around me are closed for the year. Oh well intakes will be here soon then a tune for spring. Maybe ill take out my spare and stuff too next time lol

Also I ran a 13.3 in 95 degree weather before too
