I ran my 02 A4 friday with only Vararam, Borla catback, hypertech,and P&P throttle body. My 60' was between 1.9 and 2.0 with consistant 13.1-13.2 in the 1/4. How is that? BTW still running on stock runflats.

 

Those are very good times considering your mods. I assume you have 3.15 gears, if you have 2.73 gears those times are even more impressive. What was your MPH?

 

2.73 gears....mph in the 1/4 was 107 consistant

 

Wow!! it looks like you have a strong one

 

I have similar mods but a 3.15. Cars best qtr mile ET is 12.71 with a 180 pound driver. I am around 260 my best time in it has been 12.81. I squeaked out an extra 1-2 tenths by experimenting with my shift speed points using the hypertech III. If you have not followed the test and tune instructions on shift points yet give it a shot gave me a pleasant surprise at the track.

 

A 1.9 60 foot is doing great on run-flats.

Sounds good to me......

I think that your another person w/ 2.73's that would be in th 13.3-13.5 range bone stock...

Everyone thinks we run high 13's so way to represent what the 2.73 can do with an obviously good driver...1.9 60 FTS...WOW!!!!

 

What would the estimated 1/4 mile time be, for an 04 auto, with air intake,exhaust and 3:73's with a 2800 stall converter, running stock run flats?

I am just curious........

 

I think you could run a 12.5.

 

Mid to high 13s. Ask me how I know.

With that setup, you will never get traction.

The week after I did my 3.42s and Protorque 2400 stall, I went to the track and could not break 13.552. I was running on my stock runflats, not willing to believe that I "needed" drag radials.

My 60ft times were in the 2.3, 2.4 range. Actually my worse that day was 2.437, I'm looking at the slip right now. I had 10 runs that day and nearly hit the wall due to the excessive spin on at least one of them

I have the 10 slips stapled together. I am looking at a 14.312, a 13.927 and a worst of 15.928. I remember that one cause it was one of the ones I nearly hit the wall and had to come out of. It was a 2.169 60. My 1/8mile MPH was 70.09. My 1/4 mile MPH on that run was a blistering 72.11mph because I literally had to come off the gas completely the spinning was so bad. Completely through 1st and 2nd gear.

My best ET that day was 13.552 at 103.93 MPH. Had I been on 3.73s and a 2800 stall it would have been a lot worse. It was like driving on ice. Launching was a nightmare. I tried everything, 1/2 throttle launch, 1/3 throttle launch, launch from idle, power braking and going to 1/2 throttle or 1/3 throttle or full throttle.

I laugh about it now as I bought drag radials mounted on Z06 chrome wheels from a forum member that next week. But its embarrasing to admit that I was that stupid to run that setup on runflats.

In fairness to the guys here, they didn't laugh at me. At least not in my face anyway In fact, when I told them that I was headed to the track with this setup on runflats, they wished me luck, offered advice, but warned me that I would still have absolutely no idea what the gear and TC upgrade had done for me after this trip. How right they were.

If you are contemplating this set up, then do yourself a favor and invest in a good set of drag radials and a line lock. Lose the runcraps and don't risk cracking your car into pieces against the wall.

I'll do you one better and say, don't even think about running that setup, don't even joke about running that setup on runflats.

From a 60ft time of 2.437 on runflats to a 1.831 on BFG DRs.......you do the math.

 

I missed this reply (sorry)

Yikes......

I have gotten the car back from DTE with the 3:73's and 2800 yank. The tuner said I needed 300 miles on the rear end prior to "getting on it". With the rain, and holidays, I have so far only put about 200 miles on it. I have been a good boy and stayed outta the go fast peddle. I love the way the car feels so far, and look forward to being able to mash the gas peddle and see what happens. It sounds, like i will have some serious traction issues? Rut Roh.........I didn't think that would be a real concern. Heck prior to this, with my 3:15's I could hardly turn the tires over on a hot day, without power braking.

I don't want to lose the the aspect of run flats. looks like i may need to look for a sticky type run flat tire?

 

I just got my car back last week also with DTE 3.73's installed by FLP. I have about 150 on it so far. Oh the agony of break in.

 

HEHEHEHEHEHE

I just went out for a ride. I now have about 225 miles. I figured what the hell and while i was going about 30 I put it at about 80% WOT, and YIKES!!!!

Damn thing kicked in the traction control. That NEVER would have happened prior to the rear end swap at 80% WOT.

Did you do a Torque convertor also?

 

See my sig. I have a Yank 3000 that went in with 3.42's, and the FLP level 4 tranny. These were put in about 18 months ago to protect the drivetrain from the added power of the blower. The 3.42's were from a low mileage '02 from Xtreme Motorsports. The 3.42's started growling in September. I'm hoping these 3.73's will last much longer.

 

Sweet!
