Vararam Works!
OK,
See my sig for mods, which is basically non-existant, other than the Vararam, which was installed last week. Stock 2.73 gear ratio.
Took the car to Atco Raceway today after work. I got 3 runs off before having to get home. Temp was close to 90, so not ideal conditions. Tires are Michelin Pilot Sport A/S Run-Flats (<-yes, run flats).
I did not lower pressure in the tires, or do anything special. Basically, daily driver condition. I ran through waterbox (don't have a choice at Atco) and did a burnout before each run.
First run:
Basically stomped on the peddle.
13.4@106
Second run:
Brought the car up to ~2K rpm
13.1@107
Third run:
Brought the car up to ~2.5k rpm
13.0@109
By all accounts, a stock auto should be ~13.4-13.5sec range, right?
Unfortunately, I don't have any times before the install.
Does this mean I'm actually getting .4-.5sec in the 1/4mile? Sounds logical, and sounds similar to many other experiences. I'd say the Vararam is worth every penny (and that was 30500 pennies from LAPD).
Next up is installing 3.42's and a High Stall. That and some real tires and I should be in mid to high 12's.
Comments?

don't quite know what you mean when you say you brought the car up to 2000 then to 2500----with an A4---you mean you power braked it when you launched ?? rev'd it up to 2000 with your foot on the brake then released brake and stepped on throttle all at once ???
If so you must have a stall converter because I have a stock A4 and there is no way i can hit 2000 RPM sitting still in drive---Just curious

You forgot the Stainless inserts. Must have added weight to help me hook up.

IMO it's dangerous to go modified to the track and compare your run time to what you hear people tend to run. Without knowing what your car runs at your specific track under similar conditions, it's difficult to know how much time the Vararam actually netted you. Your car could have very well hit 13.20's stock.
I got a baseline dyno on my 99 MN6 with a Vararam and Z06 Ti catback, and the best hp was 317. I can assume I picked up 12-17whp from the Vararam and Ti, because my generation of LS1's tend to be at 300-305, but I didn't have a baseline, so I'll never know for sure. Even assuming the Vararam is good for 20whp, I don't think that would translate into a 1/2 second improvement at the strip. I would think you'd pick up 1/10 for every 10hp at best...

Here are my results for some of my early mods. 4 degree temp difference when I did the testing.
Stock Timeslips (not too shabby)
12.939 @ 110.22
(Temperature at around 50-52 degrees)
Motive 4.10 Gear/ET Streets Timeslips
12.618 @ 110.43
(Launching at 4500-5000 with temperature at 64 degrees)
VaraRam Intake Timeslips
12.173 @ 112.22 (best trap at 113.17)
I can't believe this intake!

With that being said, I still think with a little more practice on the launch, I could get into the 12's. So even picking up .2 is pretty good for a bolt on.
For your dyno runs, I'm surprised you picked up that much. Most intakes don't even show up on dynos at all. But the dyno is a static measurement, where at speed I think is where "ram air" type intakes shine. So maybe only 10hp on dyno, but at WOT, more like 30hp.
One thing is certain. My wife, who doesn't know what an intake is, drove the car and said if felt faster. Also, a co-worker said the exhaust (and drone) was much louder. I'm not trying to shill for a product, but really think it does what it advertises.

I just installed my Vararam last week on my 2000 A4, 2.73 gear. I did a run with the G-tech before and it ran 13.5 @ 107.x (don't remember the exact number, it's on the computer at home). After the install it ran 13.4 @ 107.x. The temperature and air pressure were very similar both days. I was a little disappointed that the increase was so small, but this was after driving it about 1/2 hr after the install; maybe it wasn't enough time for it to adjust? These runs were just stomping on it right from idle.
When I stomp on it right off idle, it sometimes gives a very small tire chirp, but that's all. Is that consistent with yours on the steet? I know the 2.73 gears hurt the launch. How did you do a burnout at the track; brakes on lightly and hit the gas? What RPM did you hold it at?

Cobraboy, You need to powerbrake that bad boy.
Hold the brake and the gas at the same time.
When you launch, launch from around 3k rpm's, if your tires still stick, go higher, if they spin all over, try 2500 and so on.
The GTECH is a good practice tool.

On cool nights in the fall and spring you can get some pretty amazing times.
