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.

All non-WLTP ones.
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!

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).

Regardless, I think a simple tune would reduce or even reverse the gap. :)

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.

Looking up with the vin decoder from another thread. All the launch editions have the B58c

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

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.

That's what I wondered. Atleast there seems to be space to fit quite a large radiator up front.

^^ 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.

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?

If I am not mistaken the B58D is simply the B58B30O1, or the regular manifold variant.

I've seen that the estimated turbo is at 10-11 psi. Should be good for atleast 15 I'd imagine. Every 1 psi is good for around 10hp.
