3,000 to 8,000 3rd gear test,

[api330]

Just read about the 3rd gear 3 to 8000 rpm test and i am thinking i will give this ago as i don't fancy putting it on the rollers but would like to know how close it is to the time my car should set for this test, My car feels really strong on its power to me and when i have been out on runs with friends with 400 odd bhp cars and i can keep up with no probs and i have owned quite a few 400 odd bhp cars and think i am quite a good judge of power, so could any one tell me the time i should be doing on this test for a car with most it's 420 horses, I know there will be lots of factors involved in times so i am after a rough idea of a time i could hope for, Maybe we could start a table of times and if people know there bhp figure's we could use this as a benchmark figures for bhp against times, As i say i know it would not be an exact science but would be quite interesting (obviously on closed roads) Cheers Tim. (apolages if this has already been done)

Hi Tim.

Im quite a fan of this test, according to a guy on the forum called Arthur (and beleive me, he seems extremely knowledgable!) a stock RS4 should be doing it in 8.5 seconds. Mines doing it just over, about 8.8 on average. All my testing is on flat ground and 550m above sea level. What times are you getting??

Yes i have chatted to arthur before and although he gets some stick on here he knows his facts and figures for sure, I have not done it yet as have only just heard about the test but i will be doing it very soon (on a private road of course) and will post my times, Seems like a good test for checking power figures with there seeming to be a lot of chat about carbon build up taking loads of power away from our cars when being put on rolling roads for power runs, I used to do lots of dyno runs in my scooby/evo days as i was always doing various updates to my cars and i could not believe the difference between different rolling roads so never really knowing what my cars power really was, So was thinking this test would be useful,

Ive tried this test once, need to try it a few more times to get an average. But it was similar 8.7/8. Taking it to the rollers tomorrow to see what shes kicking! So then we can see times against power etc

8.5 to 8.8 sec is basically factory spec and what mags got when testing
using all gears for the same speed range 36-96 mph takes a bit over 8 sec, goes to show how flexible/elastic this engine is

start at 2000 rpm and ease into the throttle and try to hit full throttle ~2700 or so
do at least 3 or 4 runs on the same road, same day
and play with the OBC timer a bit before the runs to get familiar with it

I have a spreadsheet with over 200 runs and at least 60 cars, probably more that I have entered
people just send them to me, lol
need
temp
fuel load, 60% etc.
road grade, level, uphill, etc.
altitude (btw 8,8 at 550 m ASL is great, that is an 5-6% HP loss! much more than carbon, 20-25 HP)
cleaned or uncleaned
mileage

I love you Arthur!

I love you Arthur!

+1..Arthur is the man the 3k to 8k test is the best way to determine how yours is running...like Arthur says it should be done over a few runs ...

[j-marksie]

Well just left the rolling road, results are pretty much what I expected, 360hp at the wheels, fuel mixture perfect apparently. Looks like I'll be doing a carbon clean soon

you should do a few 3k-8k runs now then take the average, so you know roughly that your 360 at the wheels is about x.xx in the 3-8k test.
then get it cleaned take it back to the same dyno and see what bhp you have gained, then repeat the 3k-8k test and take the average.
then arthur can do some maths and tell you if the time you have picked up in the 3k-8k test is equal to the bhp gained from the carbon clean.

[j-marksie]

Yeah I'm going to run a few 3-8k tests now to get the average like you said. Then carbon clean as the car has done 68,000 and never had one that I know of. Going to have a read of that thread recently made for carbon cleaning

If you've got any questions feel free to pm me, just done the job myself so can point you in the right direction.

[j-marksie]

Ideal thank you very much will prob take you up on that I took a video of mine on the rollers today would post it up but don't know how too lol!? Do I have to put it on you tube first then hyper link it?

[ArthurPE]

I love you Arthur!

lol
back at you guys

these cars are large investments (at least for me) and should be a source of enjoyment, not something to fret over, especially over such minor issues

I've been playing with mine lately to see how efficient it can be
60 mile trip, office to a meeting and then home, rural roads, avg 40 mph (speed limit 35 to 55), 20 stop lights, a few construction zones
31.7 mpg on the OBC, mine reads a bit less than 1 high, so at least 30, close to 31
that included starting with a cold car, they suck gas when cold

took another with a passenger, same conditions, 70 miles, 30.6 on the OBC

I was trying: observe the limits within 5 mph, coasting to stop lights, short shift, etc.
regardless, that is amazing: a 400+ HP, 4000 lb, AWD car doing ~30 mpg!?

I appreciate this machine and the only issue I have with it is that it can't be driven as intended
2nd gear is almost 70 mph, 3rd forget about it, almost 100
top speed even limited is ~160

getting ready to wash mine, and yes, I even enjoy that, lol

That's my point about rolling roads, your car is doing the correct figure for the 3 to 8,000 test give or take a tenth when tested from new by various car testers not audi, yet its only 360bhp according to the rollers, So if it's doing the correct figures how can it only be 360bhp, Your figure was about 2 tenths down on the test yet it is 80 hp down, Don't think i would want to spend £800 on a clean to get me 2 tenths on the test i could fart when hitting the throttle and loose more than 2 tenths,

I am going out tomorrow to test mine, Cheers Tim.

[api330]

Could not wait till tomorrow so have been out and done mine, Did 8 runs and the time that come up 4 out of the 8 times was 8.7 seconds couple of just above 8.8 and 8.9 and one at 8.5 and one at 9.7 but think i pressed a bit early on the start on that one so going by the amount of times i hit 8.7 i would say that was my time , Temp was 6 degree's 1/2 tank of fuel and i am 600 feet above sea level flat ground but not dead straight bit of a bend all the way. Now for me that is approx what the testers where getting when cars where new so i think my car should have just about all of its power, ( Arthur this is where you come in) Could do with some of you chaps who know they are running 400 odd to do some tests on there cars and post the results, (know as in been on rollers and told there cars are this or that power according to the rollers) Cheers.
