My volcano RS2 Avant

Glad the numbers are adding up.

Wtf means 3.3 secs fats?

for some reason if i use the last entry on the graph it takes it close to 386whp which doesnt make sense, which is why i said another run being well over 6600rpm would be better.

386whp is more than Ross and wouldnt give 3.3 fats, esp if mine is giving 3.0 and lower and its about that area of whp

[prj]

I agree, I don't think it's making more than 350 whp.

[A80Avant]

for some trigger error from vems i tend to disregard high rev numbers as well, as sometimes you get a jump on the needle and you end up with weird numbers anyway. I have to get all those cars that you have tuned now Dmitri with the perfomance box! it would be a nice comparison

Thanks Andy.
A run between 4200/6500...
But it depends wich kind of gear ratio you do have true?

For example my 3gear its MUCH more short than the normal 3b boxes..that means less time spent during the FATS. ,I am right?

[Avantus]

Just got home. Running great

Dropped of my mate, and after that I did 3 more FATS runs on motorway nearby that are ultra flat.
3 times low 3.3 sec. So that is with me alone, a bit less then half a tank, and about 10kg luggage. The M20 (or what is it ) towards Folkestone is constantly up and down, and we thought it was pretty flat, but as it seems there is pretty much no difference between 2 persons or one so that must have been very slightly downhill.

I do think that my stock downpipe must be blocking flow, and causing that it spools only around 3800rpm when doing a FATS. It's even dented up a bit, so a 3" might help a bit on that, correct?

Here is one of the flat solo logs. Tiresize is stock 225/45/17, I'm 75kg, all the rest is stated above, and I don't know the exact weight of my car, but it's a full option one.

3,95 3080
4,26 3200
4,63 3320
4,93 3520
5,31 3640
5,7 3920
6,08 4200
6,5 4520
6,93 4800
7,35 5160
7,81 5440
8,25 5760
8,69 6040
9,15 6320
9,66 6600

[A80Avant]

with these values, i used:

weight: im not sure if the sunroof is on the 1595kg from stock, so i took it to 1650+30kg of fuel at the time: 1680+75+15 for total
Tyres put on the graph

turns out 357whp and 309ftlb torque.

the less torque could be explained from the previous run due to some kind of incline on the road. Ill produce a photo shortly for you!

[Avantus]

Thanks!

Some more interesting stuff about the intake temps:

starting in 3rd at 12.6°C
end of 3rd: 15.4
end of 4th: 25.9
end of 5th: 34.3
6th at 6600: 39.2

10sec later it was back to 23°C lol.

All in gemany ofcourse.

[Avantus]

Oiltemperatures however certainly stay cooler then before. It was at 95°C on that run, so barely moved.

[prj]

Sounds good to me.
It should be between 400 and 430 hp.

Have fun with the car, and I hope everything will be mechanically sound for a long time to come.

And yes, oil temps should be better, because it won't knock.
I have noticed that oil temps go up FAST if the engine is knocking.

[Avantus]

That's the objective, doing some more reliable cool roadtrips while having this bit more oomph

[A80Avant]

here is the photo with the weights i have used for both runs



as you can see very different runs but roughly same whp.

possibly the higher torque could have been slight downhill, or wrong weight

[A80Avant]

If you can manage to get a run done from 2500-6900rpm that would yield a better graph!

Will do some more yes
thank for the graph!

Last run was 100% flat. Got 2 other flat ones , but they are all identical up to .05 of eachother, all 3.3s.
