Do you maybe remember boost and timing figures of this run?

In the last run before, where you took 6.5 seconds for 100-200 km/h, you've written that it was 24-25 psi and 13-14 degrees of timing.

So I guess with this cited run these figures were even higher.

Btw: What is your mileage meanwhile? No issues so far concerning your transmission?

I see you quote Glemm, but i have the log when i did 6.25sec 100-200 with 60000km running PURE800, 93oct (No meth, no Ethanol), DS2 HPFP (DI Only). 27PSI 6.5Timing. Im guessing that 24-25PSI with 13-14 will for sure make that time. After that my octane rating was not enough. Trans in my car is still stock running 4.9sec 100-200 with way more boost and timing.

@jav140i

which pistons and rods do you have installed?

Thanks mate. I'm curious why you decided on only 6.5 degrees of advanced timing? I tried lots of revisions of my 93 oct map and the sweet spot were 9 degrees.

And how much boost/timing are you running with your big map (E40?)? I guess around 29/30 psi and up to 18 degrees of timing?

93oct: 27.5psi 6.5 timing (6.25sec 100-200)
E55 Flex Fuel: 28.5-29.0psi 18 timing (5.6sec 100-200)
E85 Flex Fuel + PI Rail: 38 psi 20 timing (4.8-4.9sec 100-200)

Low timing because of bad fueling, once i did E85 no problems increasing timing and boost of course. E85 time is improvable up to 4.5sec 100-200 problem was grip and summer heat.
I did E55 just bad 93oct fuel. If not E40 can push more before finding the HPFP/Injectors Limit. Seen 5.10 sec 100-200 with E40

If you are from Germany with Aral102 you can push less than 5sec for sure, even with 93 you can do better than my time with proper tune because your country fuel is way better

Great results and thanks for the insights! Can you maybe share your 93 oct log?

You're right with the fuel here in Germany. That's why I told my tuner to try 25 psi and 14 degrees timing for 102 RON. But still have to log the tune.

thx bro,

why so high CR?

My gen 1 b58 has 11:1 ratio stock, the G42 240i that has gen 2 uses less cr. Depends on goals but if i don't build my engine i prefer lower cr like yours. Recently a gen 2 340i made 1000whp stock bottom block, i don't know if a gen 1 stock can get there really
