e65

at the track I go to the reaction time is subtracted from the total time. I imagine it would be the same for any NHRA track.

cocobeex

So, final result is already subtracted RT ?

Can you tell from this time slip ?

chiromikey

No, reaction time is NOT subtracted from elapsed time...and shouldn't be at any track. R/T is the time it takes for you to start the clock after the green light comes on but the clock doesn't start measuring E/T until you actually start moving.

e65

RT is not included in the 1/4 mile or the other distances as well like 1/8 mile, 60 foot etc.

cocobeex

Thanks for the explanation!!!

Ralcbah

Congrats man! You've built a quick car there. Nice job.

kponti

Nope, RT has no effect on quarter mile track times

PeterUbers

My understanding is that car mag testers use a one foot roll out before the 0-60 or 1/4 mile clock starts

what's the point of that??

If anyone is looking for a second ECU, I'm selling my spare. Works flawlessly...you'll need to clone your OEM ECU to this one. $1,050 shipped to you in the US. Thread in the classifieds.

Also selling a 2 month old PedalBox+ for 250 shipped (100 off). Thread in classifieds

Track night this evening.....so close to 10 second car. Ran many passes at a pretty consistent 11.0x ET with mid to high 120s for trap speed.

Last time at the track I used race start each time. This evening I brake torqued to 3k rpms and launched...consistent 1.6x 60ft....great.

Have a new problem. Getting much too wheelspin after second gear shift.

Ran the car with half tank of 93 octane with 12 oz of methanol added. Next time will run on 93 octane only for a few passes, just for S&Gs.

Getting closer....

chiromikey

Great 60ft times. I've been able to get close but at the expense of neglecting the tree...and I hate being tree'd!!!!

What was DA?

Ralcbah

yeah man, i'm with you on the tree thing! had a few of those...haha.

Da was 1800. Was actually a great night. Storm was supposed to pass through, but missed us, so the air was cooler. Breezy 81 degrees.

Gives a much more realistic and repeatable time as opposed to a brake standing-prepped drag strip glory number.

Ralcbah, fantastic results with your mods.
Strike that, fantastic results period.

Ralcbah

Thanks man! It's been a blast of a journey, and still having a good time.

If you got rid of the baby seat and everything else you have in the trunk you'd have 10s jokes aside nice to meet you man, sick ride!

Ralcbah

Good to meet you as well bro! Yeah man...I took one car seat out for last night's runs. Next week I'll take the other one out. Gotta make this as dramatic as possible. Hah

Turned on the Vbox for fun today...0-60 results below. Did a few quick pulls on the street. Tried in 'sport' and 'traction control off' modes...both resulted in spinning tires. This is probably the best I'll do on the street with these tires.

3.25s

Used to see consistent 3.5-3.7s, so this is an improvement.

Still blows my mind that these cars (the E63 and it's competition) can do this.

Will use the Vbox on a prepped track next time I go. Should be a little better.

Ralcbah

Ordered RacingBrake front rotors and pads; should have them installed in next week or so. Will provide some pics/review and such.

Also having the Revozport rear diffuser being made now. Also to be installed in next few weeks.

Ralcbah

10 seconds and then rain. Yeeaahhh

91 degrees.

PeterUbers

nice work man,

friggen 130mph trap ... damn, son, M5 killer

Savage212

Awesome dude!! Just filters, tune and wm?

Ralcbah

Thanks man! Havin some fun

Thanks! Upd intake spacers with BMC filters, catless downpipes (not turbo back), tune, and running boost juice in wm injection system. Tonight ran some Sunoco gt260plus with 93 octane. Also lowered front tire pressure a bit more. Both may have helped.

cocobeex

Congrats!!!!! 10s car!!!! what a BEAST!!!

Savage212

Where are all the RS7 nut swingers?? LOL

chiromikey

Probably somewhere laughing and talking about 9s...
