German850R Posted September 12, 2014 Report Share Posted September 12, 2014 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: https://www.dropbox.com/sh/434u1l7e56wv1s7/AADNQohB6tjkSn8kNVlYxJ97a?dl=0 The xlsx file contains the data formatted a little bit for better reading and the tab "Sheet 1" contains the 60-250kph pull.

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.

German850R Posted September 15, 2014 Author Report Share Posted September 15, 2014 Yeah, it's not too bad. What do you think about the coolant temps? I think they are a bit high, if I'm honest. Water cooler, water pump, coolant, piping etc. is all new. Link to comment Share on other sites More sharing options...
German850R Posted November 10, 2014 Author Report Share Posted November 10, 2014 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.
