E89 Mods and Experiences

[R.E92]

This is all really useful - thanks for posting! Worth posting in the logs thread perhaps? With regards to oil temp, it really depends on where I'm driving - in town it can go up to 120C if I fool around, but during normal / mixed driving it usually sits 100C if I recall correctly.

I'm looking to Dyno the car in the coming weeks, will make sure to post the results here / in logs thread.

My friend has a stage 2 (decat) E92 M3 DCT which I'm hoping my Z4 would pull on. Wonder if it's strong enough for that.

I'm trying to work out if my thermostat is stuck open as I don't remember the oil ever getting stuck below 100C during any of the previous winters.

I think it'll be even with the M3, against a stock car you'd be away but that decat and tune will have him around 450bhp.

I use in Finland MHD Stage 2+ E85 software. Dyno result 460hv
100-200km/h 9s Dragy measurement.
62-124 miles 9s.

9s is impressive. I haven't timed mine since I installed catless downpipes, when it stops raining here I'll see what times I can put down.

I don't have access to E85 so I'm expecting something around 9.2s for 62-124. I managed 9.44 last time and 11.0 in for 60-130mph but I don't have the balls to hit 130 when it's cold and wet

Who does your tune? I'd imagine you're using tmap scaling to go above 18.5PSI.

Standard MHD Stage 2+ E85 60 software.
i use 80% for E85 and 98 ron 20% a mixture of, works fine with this setup. Original low pressure fuel pump.
