11.42 @ 119 . not bad, tires not the best.
I expected the mph to be higher ?????

TLTONEY

What was your 60' times?

theVcar

Should be, b/c I ran 12.5 @ 118.xmph

stanger383

I would expect higher as well. post a timeslip so we can disect it. Were you able to apply full throttle in the lower gears without wheel spin ?

BELLMAN

I'm having trouble with my photobucket uploading so I'll break it down:

Here is the best pass. not sure what to think of the 60', i couldn't duplicate it. but the balance of the run is also quicker ?????

60' 1.6390
330 4.8242
594' 6.9049
1/8 7.3732
1/8mph 96.10
1/4et 11.4271
1/4mph 118.34


My other passes looked more like this:

60' 1.9132
330 5.0528
594 7.1222
1/8 7.5918
1/8mph 95.80
1/4et 11.594
1/4mph 119.04

let's disect this turd. not impressed with it for 560 rwhp.

I could apply full throttle, but would start spinning as it built boost in first and second gear. (top of gears)

You cut a 1.63 sixty foot on Invos? I'm not a drag strip guy, but that's impressive on street tires!

BELLMAN

Need some input on runs please. The mph is off. Could slipping trans be the culprit?
I think the A6 sucks.

pit-man

Yeah the mph is way down. Actually the ET is off as well, with the good sixty foot you had on that one run. Something is going on !!

That puppy should be in the high tens and around 132+mph

BELLMAN

Trans acting real goofy normal driving. Was building 6-7 lbs boost.

pit-man

Did you have the trans built up yet ?

BELLMAN

No. It's stock and tired.

I wish I could offer input on the A6 but I run the A4. I agree that that think should mph out the azz! ~120 is what 400-415 runs I believe. You ever log runs with HP tuners?

pit-man

We just put a new 402 stroker with a procharger in my friends 2007. He had the tranny (A6) reworked. I will let you know how it turns out. He is going to be over 700 rwhp..dyno coming next weekend.

Awesome short time! With N/A 450whp,M6,& M/T Drag radials my very best on a competition prepped track was 1.79-60', 11.39 @ 121/122mph. I thought I was missing a couple mph on that run and should've seen 124ish.

Maybe I missed where your track is but altitude can be a huge factor. My run was at Memphis and comparing a M6 w/ DR, to an A6 w/ Nittos is probably apples an oranges, but for what is worth, I'm w/ pit-man. I'd expect 10 second slip w/ 130+mph.

Another thought is despite a great short time, your still having wheel spin issues, so feathering, lifting, or short shifting the top of 1st, 2nd, and possibly 3rd is definately going to have a negative impact on your ET and you MPH.

As precaution you can try to logging some runs to make sure the big things are in line, like AFR, Timing, KR. Yeah, you may be battling convertor or transmission slippage, but its hard to tell how far off your run is unless it is WOT through the higher gears. You could be missing 10mph at the big end because you never got up to 110mph by half track.

I have 05 A4 A&A SC with 560 RWHP. I have Invos 325/30/R19 in the rear. What tire pressure do you run on your Invos and do you launch with the TC on, comp mode or off? My launches on the street will not go straight line. Haven't gone to the track yet.
Thanks

BELLMAN

I turned TC off, 28psi in tires. Tried from idle, then slightly higher rpm(best short time), then started brining it up against the convertor later. My best was early runs.
