There are actually differences between the B58B30M1 and B58B30O1.Probably just gonna be a tuned b58, doubt they are gonna put in a s58

Thank you sir. All markets to receive the O1?B58D.
(Nice to see someone who knows all the right letters.)
All non-WLTP ones.Thank you sir. All markets to receive the O1?
Awesome, thank you. I am not sure what Australia gets - we're not subject to WLTP but the cars we receive often have it due to parent markets.All non-WLTP ones.
Different dynos, DA, gear, etc. The two Supra dynos we saw so far have similar hp numbers but quite different torque figures. Those we can barely compare if we can assume the torque difference is due to the gear selected. The Z4 numbers simply have too many variables to be compared to and way to much torque if it's in 6th gear (1:1).The z4 dynoed 373 hp and 425 ft lbs to the wheels. The supra dynoed 339 and 427.
I'm sure the supra has 34hp left on the table with a tune.
Yes, all current right hand drive 40i's are DB42. And it doesn't look like the cars for your market get the European emissions equipment, which suggests you could get B58D.Awesome, thank you. I am not sure what Australia gets - we're not subject to WLTP but the cars we receive often have it due to parent markets.
Is there a way to decipher from a BMW-perspective what cars are subject to WLTP? I'm guessing Au gets the DB42 cars?
Thanks!
That's what I wondered. Atleast there seems to be space to fit quite a large radiator up front.What I wonder about is the affect on the cooling system at higher power levels, where the heat generated by the engine becomes so great that it has a detrimental effect on the cooling system, possibly even the thermal expansion rates of the alloy....
Again, no data to back it up, but some things I wonder about.
^^ To your point, sometime back A70 had mentioned the current B58 in the Supra which has the integrated exhaust manifold was tested by the development team in at least one prototype car up to 600-700hp. No mention of what was done to get there, how well it ran or what the expected lifespan loss was like at that tune assuming a stock bottom and top end but if true then your hunch may be correct. At least to a point.Looking at engineering of a headifold manifold like the supra has. It looks like it could be possible to have more fuel with it cooled the way it is. I mean the capability to run more boost because the engine uses less fuel for cooling
If I am not mistaken the B58D is simply the B58B30O1, or the regular manifold variant.^^ To your point, sometime back A70 had mentioned the current B58 in the Supra which has the integrated exhaust manifold was tested by the development team in at least one prototype car up to 600-700hp.

Does this higher spec B58 “D” retain the integrated exhaust manifold or does it get the traditional 6-port head that the 382hp Z4 already has?
