My volcano RS2 Avant

[A80Avant]

why shouldnt he be? 400hp and potential for more! that is always nice to have.

good job! Lets hope he doesnt get the wrath of boost leaks now! I bet the cold weather must have been nice for mapping!

what were the IATs at the end of 3d or 4th gear pulls?

[prj]

About 9c ambient, IAT's at end of 3rd were around 24 at end of 4th up to 26-28 and 5th was low 30.

So I think no point to push more boost, as it will be bad in summer.

[A80Avant]

yeah, absolutely right!

time for that water meth then!

[Rocco]

Dmitri,so is Avantus mapping much the same as it was mine for example? i think he should have more CR than mine... because you know i bought a 8.8:1CR head gasket...caused because my Cylinder head was skimmed at least 2 times a little

[Avantus]

Just checked in at a nice Hotel. First of all big thanks to Lloyd for having us there to meet up, and have a nice mapping day. Also for providing me with a new MAF, appreciate it!

But ofcourse also Prj, who did a great job on the car... First of a bit of issues with boost pressure and oscillations, but after some tweaking with the WG and fine-tuning, the endresult is something I'm very happy with!
It now feels faster with 3 persons in the car, then it did previously with me alone on the 1.9bar v-stream map and stock components,

Very strong and smooth delivery, with good top end power imo.
Oh and Dmitri, we saw up to 1.85bar in 4th up to 6th gear on the motorway... it's then that we felt the massive difference to before

We'll do some FATS runs on the way home tomorrow, and I'll also do some alone when I get home, and give some logs to do a virtualdyno with.

Thanks again, was a pleasure!

[Avantus]

I'll also check IAT's when doing normal driving a doing a pull, because today wasn't ideal for it. Doing a pull, then standing at the traffic lights for a minute, and right after that doing the next one... it builds up heat quite a bit.

Power delivery and boost profile on the faster runs on our way back now was very impressive, well pleased

[Rocco]

Glad to heard this.I know how are you feeling now

[A80Avant]

Good stuff! enjoy! and get some results up soon!

i also noticed that you went with mahle pistons as well. are they the 81.26mm or the 81.50mm?

[Avantus]

First oversize Mahle 81.26

Forgot that my boost gauge underreads 0.1, so that means boost actually gets up to 1.95 bar in the highest gears on motorway. No hesitation and mighty torque, just as we like it

[Simoni]

jealous

[A80Avant]

yeah,higher gears may always yield a bit more boost

[Avantus]

First FATS on flat motorway towards Folkestone is 3.344 with 2 people+stuff and full tank of Tesco 99.

here is the data for anyone who knows to use virtualdyno correctly.

3rd gear:

6,12 3000
6,44 3080
6,75 3200
7,14 3320
7,56 3520
7,97 3720
8,39 3960
8,84 4280
9,3 4640
9,73 5000
10,16 5280
10,58 5600
10,98 5840
11,41 6080
11,9 6400
12,38 6680

[A80Avant]

ill get on to it.

i need your wheel diameter, and size as well as approximate weight (how full the tank, driver)

[A80Avant]

with an estimate weight of 1820Kg virtual dyno shows around 355whp and 351ftlbs.

however, i used 225/45/17 wheels and weight needs to be readujsted.

also a run up to 7000rpm needs to be done, as for some reason the last measurement gets pulled too high, i think a log problem.

3.3sec seems very good and reasonable with those numbers.

[Rocco]

Wtf means 3.3 secs fats?
