Yeah Drew I needed 2 cars , was doing too much km's a month with the M3 and it allready had 170.000km on the clock, I got a very nice price (23k) for it and bought 2 cars , One daily and my old S4 that I sold 2 years ago to a friend!
Hopefully the S will beat my 60-130mph time , we will see when the new hose is fitted, The VBOX is allready plugged in haha
Your cars are both wicked fast, Evil's car is one of the reasons I bought an S4, just like Drew's clips always motivated me to go Supercharged in the ///M !
Just put on the new hose, Did one quick run to test if the hose was fitted correctly , it was ...
Then one 100-200km/h, did a 9.5 with a crappy shift on a slight incline , I think on a nice straight piece of road with a good shift I can get it in the 8's
Me (200lbs) and 3/4 tank of pump gas
Will try on a straight highway with 1/4 tank of 100oct I have in the garage!
You should be able to improve on that easily. What was the ambient temp and how much does your car weigh?
Try a 4th gear-only pull as well. I'm fairly confident that will be quicker, especially from 100-200, since starting from 62mph is a lot better than 60mph in that gear. However, you do have longer ratios and probably faster boost recovery than mine, so it might be a wash between that and a one shift pull.

Ditch the spare and get a can of foam and a plug kit instead, that is 20kgs right there. Most new cars don't even come with spare tires.
BTW, do you know what stock S4's pull at MRC's dyno? (whp and calculated crank). The drivetrain losses seem quite low, so I wonder if it underestimates crank power or overestimates whp (like a Dastek dyno, for example).

Don't know man... They told me it measures resistance and calculates it like that, but I'm not an engineer so don't know haha
2 pages back Mike (Audisport B5S4) did a 9.2 from 60-120 and he has over 400whp If I remember correctly , My E46 with 385whp weighed about the same as my S and also did Around 9sec from 100-200 in freezing weather so I guess the WHP is about right for the mods and boost I'm running (1.5bar up to 6K rpm and then 1.25bar)
Drove the S more then 2 hours today with lot's pulls , seems to get stronger by the pull, Filled her up and drove around with 2 friends, with 2 passengers I did 9.4 from 100-200km/h
Then dropped them off and did a 8.9sec in 4th gear only from 100-200 on a slight incline road !
I'm positive the car can go 8.5 with 100octane and perfect flat road!

Good job!! With a few liteweight mods and racegas you will easily do low 8s.
I really hate the 3d to 4th gear shift if I wanna nail a good time! It doesn't seem crispy at all when I try to be as fast possible... Do you have any shifter/driveline upgrades on your car Bone_doc?
I had better set the VBOX to 60-130mph also on that run , I bet it was just under 11sec and that was my goal , to beat my S/C M3 time!
I have tested 100-200km/h times, because I don't want to rev so high on 4th gear (no gt set up...)
Times has been between 7,7 -8,2 (depending weather, shifting etc..) Logged with Tempes GTx GPS software. It's not very accurate, but only software what I have.

Nice results Makke! I really like the distance readings because it gives even better perspective than seconds how fast the car really is. Will we see standing mile (or 1700m) top speed later this summer?
Last time I tried standing mile I had speed limiter on and the result was 244km/h / ~1000m = 151,6 mph / 0,62 mile.
I might try standing mile later. I need to tune A/f ratio.
Sorry to turn this to 100-200km/h. I will also try to do 60-130mph pull. I looked one of my old files and 60-130 was 9,1s with 2 shifts 3->4->5.
Obviously last shift was just before 130mph and it took little time (~0,5s).
I did a Power Run yesterday with the VBOX wich I know is correct cause we have tested it on ALL of my friends cars and the S made 295kw at the wheels!
Excellent. How much did the car weigh? The Vbox power run (if compensating for aerodynamic drag, but not rolling resistance) should produce numbers very similar to those off a properly calibrated Mustang dyno, ie, the real power that the car is producing at the sweep rate (rpm/sec) that it sees in that gear on the road. That likely means the Cartec dyno that MRC uses also produces similar #'s to that of a Mustang dyno, not an artificially low number like Dyno Dynamics or Maha or an artificially high number like Dynojet.
However, it seems like the MRC dyno calculates a drivetrain loss that is quite low with 13% drivetrain loss for the pre tune pull and 15% loss for the after tune pull. In other words, your car should have more than 460hp at the flywheel. From my data, a selection of other cars that go 100-200 in 8.9sec are: R8V10 (takes 10.2sec if done in 4th), Lambo Murcielago (12.2s in 4th only), GTR (9.7s in 4th), F430, so pretty decent company, especially considering that you completely smoke them when they are using 4th only. The Lambo has a longer 4th, but the others have shorter ratios for 4th than the B5.

Thanks for the info guys but it makes it hard to compare when you stick to 100-200kph in a 60-130mph thread...
Good point, but I suggest that we make a list of 100-200km/h as well. Lots of other forums have lists for both 60-130mph and 100-200km/h. 100-200 is very often discussed at 6speedonline, as well as being commonly used on Rennlist, etc. With data in kmh as well as mph, it makes it easy to compare numbers with tests in European mags like Sport Auto, who has an awesome collection of performance data on their website, including in gear acceleration data in 4th gear.

I haven't weighed it but I searched the forum and most guys are around 3600lbs (1630kg) I took 1630kg + me 85kg and I had a 3/4 tank of gas but I made the figure round 1720kg all in
The more weight your car is , the more power the VBOX will show cause it takes more effort to move that weight with the same amount of power but you know that :-)
I will weigh it soon ,we have a scale nearby but this estimate will not be far off. My M3 made 268-270kw when I put in 1570kg, but it was 1600kg and made around 273-276kw on same road ,same gear so it aint that far off.
OK first off I went to see 3 diff people with the hissing whining sound my car made since a few days. 1 is my mechanic, 2 is Turbo service (shop) and 3d my good friend who works in a turbo shop and they all say I'm just over reacting with the sound and that it's not a big deal and I should just enjoy the car...
So today I did , Filled her up , I drove 250km to all those guys and some highway cruising and then put in a little Aral 100 Octane
Set the VBOX:
I did a power run with the same amount of weight I used before and it made 309 and 313kw at the wheels (415-425whp) Could be cause it's like 10° colder outside then the day my car was on the dyno and I'm running +- 99oct at the moment
All previous runs were made on the road nearby my place , it goes up and down and has some long corners (very good road but not perfect straight nor flat)
100-200 km/h with Airco on in 4th gear only: 8,5sec
Then set it to MPH and shut the airco off (I do have the idea it drives somewhat smoother at full trotthle thrue the high rpms with airco off)
60-130 mph in 4th gear only on a perfect piece of highway wich looked to go straight or a little bitsy decline : 9.6sec
^ Wow, that's really interesting.. So they move REAL fast when you don't have to shift. You started in 4th right at 60, or gave it full throttle when? Cool stuff.. Eliminating that shift makes it pretty damn fast!

I started at about 80km/h , right at about 60-65mph the car explodes in power in 4th gear. The way the needle moves at 160-170km/h is just crazy , no way I could achieve that with a shift in between. The car will be quicker from 60-100mph in 3d that's fo shure but due to the torque it can't make up for the lost time with the shift. Atleast for me with my gearbox
Interesting, and just as I thought. Mine is also way quicker using 4th only. Judging by performance times listed by Sport Auto, most high torque turbo cars are quicker by doing the whole pull in 4th.
What gearbox code do you have?
Can you list the time increments for kmh and mph, starting from 100kmh and 60mph, ie time to 110, 120, 130, 140, etc. I've got a huge database for these times, and it would be interesting to compare the incremental times to Porsches, etc.
Go weigh the car at the DMV, truck stop, scrapyard, etc, as its weight can differ from listed weight. Fill the tank before you do it, so you know how much gas is on board.
