How consistant is your car?

Mine's pretty good.

The car did well ets were 11.07, 11.08, 11.07 for testing.
Then dialed 11.08 ran 11.083, the next race I had him covered and ran a 11.179 letting off.
After the sun went down it went 11.059 on a 11.08 dial, it was double breakout with me winning, and then a 11.059 on an 11.06 dial.
The last 2 slips were like a photo copy. Totally identical to the 3rd decimal point.

Nice, mines pretty consistent too, within a couple of hundreths, but I just go for test and tune.

Are your 60' times all the same too? Weather here usually changes between runs.

my car will never be that consistent because Im an m6. But for what is worth it still runs consistently. My 60's pretty much tell the story. 2.0=13.5's. 2.1-2.2=13.6-.7.

Fixed an ignition issue and the last 3 times I've had it out all runs were within about .01. If my lights were worth a hoot I could win a few races here and there.

In a word to describe how consistant, "Very"

Yeah on all the passes the 60s were all 1.50-1.51.
The last 2 passes were 1.504s. These runs were only 5 or 6 minutes apart as they had hot lapped the street et class.

Not very! I did manage a .43 and .44 back to back with a large difference in 60 foot. Bad 60 foot doesn't hurt the ET really bad with such a long first gear. A tenth at the 60' is a tenth at the stripe from what I keep seeing.

That's a consistant car and driver. This season I went 13.694, 13.696, 13.697, and 13.705 on the brakes with a 13.70 dial, all 2.15 60' durning elimination rounds. Not bad for a stock rustang.

All I know is if I "hot lap" the car slows down. Usually the weather will change the ET by .0x between rounds, or something simple like cloud cover vs sun will happen, or the wind will change...

The other huge factor is the driver. To be that consistent you usually need to stage in the same spot each time, launch at the same rpm, shift at the same rpm, and stay in basically the same groove. I have been on one track where the ET would change based upon the location (left side/right side) of the car in the same lane... It has since been corrected.

The engine temp, tranny temp, amount of fuel in the tank, direction of the wind (if any), all play a factor.

You had some darn consistent runs.

All aluminum LS1 with plastic intake and electric water pump here and it cools down to base readings just driving back to the pits.

I'm very **** about how I stage and leave. I pay little to no attention to the other driver and do my own thing as close to exactly the same way everytime.
