Title: 300BHP verified ME7.5 BAM log Post by: IWay on February 21, 2021, 05:42:53 AM Anybody got a 300BHP verified ME7.5 BAM VisualMElooger log preferably with the 5120 hack applied.
I need to compare with my running logging before taking to dyno. Thanks Title: Re: 300BHP verified ME7.5 BAM log Post by: adam- on February 21, 2021, 01:47:51 PM On a K04? I doubt it.
Title: Re: 300BHP verified ME7.5 BAM log Post by: IWay on February 22, 2021, 01:55:27 AM Nope, hybrid with a load of other mods.
Just need a verified log so I can confirm I'm in the right ballpark before going to the dyno. Title: Re: 300BHP verified ME7.5 BAM log Post by: adam- on February 22, 2021, 11:08:44 AM Why? What variables are you looking to see? Any engine other than yours exactly will have different results.
Title: Re: 300BHP verified ME7.5 BAM log Post by: IWay on February 23, 2021, 01:58:57 AM It's just for ballpark comparisions;
- MAF - MAP - EGT - AIT - AFR - Calculated HP - Calculated Torque - ETC Not expecting it to be the same. Title: Re: 300BHP verified ME7.5 BAM log Post by: Aardschok on April 09, 2021, 03:37:36 AM Not verified... but they say 252g/s ~ 315 @ flywheel
Stock turbo & actuator on 156,000 miles Seems way too good to be true and I don't believe it's accurate, I'll get her on a dyno at some point this year. No EGT probe (converted APX) and I'm not at all happy about fuelling but ignore that Title: Re: 300BHP verified ME7.5 BAM log Post by: IWay on April 12, 2021, 01:32:45 AM Cheers I'll compare to my latest, attached.
Not sure how accurate the G/S estimate is as timing can make a lot of differance. Are you running WMI or something as the IAT is going down not up? Also to my knowledge the stock turbo (K04) & injectors should top out around 280 hp on a good day (boost leak?). Something doesn't look 100% correct, may be someone else with more experience can comment further. Title: Re: 300BHP verified ME7.5 BAM log Post by: Aardschok on April 12, 2021, 12:52:26 PM No WMI, just a big intercooler. Quite normal for IAT to drop for a short while after opening the throttle.. if mine were a 4th gear pull, the profile would look more similar to yours.
Injectors are not stock :) Has yours been on a dyno? Pretty similar in terms of acceleration (yeah, I know that's a crap comparson if we're not logging on the same piece of tarmac in the same conditions) Title: Re: 300BHP verified ME7.5 BAM log Post by: BlackT on April 12, 2021, 01:34:47 PM K04 have 0.18CFM max acording to commpresor MAP.
That mean on temperature 0 C° near sea level it will get 230+ g/s At 35 C° it will drop under 210 g/s Flow of turbo is given in cubic feet, so you need air density to convert it to air mass. And difference betwen -5 C° in winter and 35-40° at summer is huge in mass flow of that small turbo |
