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

This reminds me of the famous quote from president Teddy Roosevelt: The Man in the ArenaAgreed? :tup:

Coop

You're a real racer! You'll do low 12's soon.

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

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 !!!!!!!!

I have to check my drag slip again, Im sure it was 13, I was running a old mustang foxbody. :tup:

Will your next post tell us that you're walking toward the time slip? :icon14:

I'm sorry but I can't help it :ugh:

Just for that ill make you wait. :bowrofl:

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.

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:

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.

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

Thank you, trance.. I'll be back out to the track Fri night.

Got a 13.04 on Saturday very depressed I didn't get into the 12's :(

no prob. good luck Friday.

I've been there... ran a 13.001 before lol.

Damn that would have really pissed me off :icon17:
