I know for a fact that our ratio is over 1 for 4th, a hair over.. As you have stated there with 1.032. When we do dyno runs, you'll certainly get a higher number in 3rd because its on the low side of 1 but 4th which most people prefer for realistic data has always been stated as a bit over. What you posted is EXACTLY correct in that 7100 RPM is 124mph for us and thats where most rev limiters are.

Has anyone compared the difference between vag-com logs, and a gps based logger?
I am just finishing a GPS class at University, and there is more error in the GPS system than most people realize...without a known geological benchmark on the ground there is a good chance the GPS is off +/- 10%
Just curious...
I think this link elaborates on a few of the most common causes of GPS inaccuracy: http://www.kowoma.de/en/gps/errors.htm

lol- nothing more accurate than the good ol' butt dyno
+1 will someone with a V-box, and a vag-com go for a drive please... I curious to see how much of a difference there is

Yea I wasn't planning onto anyway. I know my car well it won't do 130 in 4th.

People who dyno in 4th gear need to realize okay it might be 1 to 1 BUT you're not going to get sufficient cooling with fans to simulate the car doing 120+MPH on the dyno. Food for thought..
3rd gear dyno unless you're making UBER power and you spin tires on the dyno in 3rd.

Thats not entirely true. Getting enough fan to simulate that kind of speed on the dyno is very difficult. On a load dyno, there is barely any noticeable between 3rd and 4th gear numbers.

What are you expecting for a 60-130 time with a clean run? I'm struggling with meth leaks in my VAST system and cant decide/find what fittings to stop the leaks
edit: sorry didnt realize that was on page 1 of 3... high 7's seems pretty solid to me

No clue, I would hope for 6s on pump gas. But you never know.
Make sure you have a good straight cut on the end of the tube that goes into the fittings. Push it in and then pull out on the tube to lock it into place. :hmm that sounded dirty:

FATs times for those who are asking really don't mean anything unless we're talking exact same stretch of road (when you're talking small variations). Example. I'll do a 3.1-3.2 on my slight incline of a road. My interpretation of the slight incline could be something most people wouldn't do because they could see it as not flat enough. When you're talking tenths of a second either direction, 2-3 tenths, the cars are identically fast.
No mike, my car at 7250 barely, and I mean barely would clear 130.

Not bad. By bumping the speed limiter so that he can stay in 4th, he will shave a second off the time. We can see from the graph that he is actually losing noticeable speed during the shift. It is at approx 124mph @ 7.75s and slows to 122mph at 8.1s, so the shift totally kills the time to 130.
100-200kmh appears to be approx 7.5s.
A 4th only 100-200 pull would most likely be closer to 7 seconds flat.

JPM: what is the approx. elevation of your Pbox test site (and dyno site)?
With so much torque vs hp, a no shift 4th gear pull is most definitely faster 100-200kmh

Dyno is at 600-15 mts over sea , where I usually test the car is at 675 mts , I did test in 4gear the measurments are about the same give or take a tens. the problem now its getting hotter with 5 degrees ( celsius)of a change the times vary 0.2-3 aprox I try to test with the same ambient temp, otherwise is not accurate.
Regards.
Here is a better pic of the Dyno.

forced induction cars are not affected as much by luck of air flow on the dyno as NA cars are. and cooling - u r doing a single pull, not repeated. u need lots of cooling if u do repeated pulls. on a dyno, u floor it once in 4th gear, by the time temperatures rise to the level where it affects the performance, u r already done. plus, many guys run W/M, which again for a single run negates any "luck" of real air. look at graphs people post of intake temperatures. on the other hand, 3 vs 4th gear is a big difference. because ratio is ratio. simple physics. go ride a multi-gear bike and tell me u do not feel difference between 1st and 2nd gear...

your airflow comment is incorrect. at a recent dyno day lacking fan, all s4s dropped significantly in power after their first 4th gear pull while two LS cars punched out numbers that were within 5hp. even if you were correct, who does a single pull on the dyno? the logs people post are done on the street with sufficient cooling, not on a dyno w/o enough fan. too bad I dumped the logs I took on the dyno. You would see the obnoxious rise in IATs. 3rd gear pulls on a load dyno FTW!

that is exactly what i said... first run it is not affected drastically. 3 vs 4th gear ratio affects every run....
your car right now is probably putting out on the street 20-30whp more then it will on 90 degrees summer day. that is a known fact.

i apologize if I misunderstood but this suggests the opposite is true.
