M4.4 850R 60-250Kph Pull / 40-155Mph - Log Files Included

Hi,

today I tried a few pulls and one of them was from 60-250kph.

I thought I share my log files with you, maybe someone has a comment or so.

I am very happy with the performance of the car for its 16T and 424000km engine but maybe someone sees something in the log files which is worth having a closer look at (maybe coolant temp?). If not, nevermind. Then just take it as a log of a DIY tuned old 850.

It feels like the engine power should be close to 290-300hp, torque probably around 430-450Nm. No idea, maybe I will dyno it once again. 100-200 kph is in the low 15s range measured by Racelogic Drift Box and after correction of down/uphill. The log shows about 16s this time, so it's close enough.

Ambient temp was 18°C.

Here are the logs:

The xlsx file contains the data formatted a little bit for better reading and the tab "Sheet 1" contains the 60-250kph pull.

Cheers

Chris

Always interesting.... logfiles.

Just for reference:

A year ago, when I still had the M4.3 Turbotuner installed, I mapped on a hubdyno.

I ended up with 285 whp (don't know how much bhp that would be) with that I did the 100 km/hr to 200km/hr within 12 sec with a 19T

So 15 sec with a16T sounds pretty good to me.

A little update here:

Ran a clean 15,0s run 100-200 kph. That's the fastest time so far with the (dying) 16T, max 1bar boost, mostly 0,8-0,9bar.

Last week we "dynoed" the car on the road using vbox sport and some calculations afterwards which had been proven to work in extensive testing and correlation to a Dynojet dyno.

The result was:

450Nm @ 3200 rpm, 285 hp @ 5400 rpm, both DIN corrected. I hope to crack the 300hp barrier when I got around refurbishing the turbo and optimized my ignition timing.
