I dont have any issues with anyone. Z8AKU is the one that turns every reply to his comment as personal attacks. I wasnt the one that started calling someone a smart ass when they made valid points. It isnt his first time he attacks other commenters either.
Toyota did lie. They stated the B58C was making 335hp when it's been proven by empirical evidence to be making closer to 390hp by all accounts of the MY20 dyno charts as well as 0-60 times and ET's from the drag strip videos plastered all over Youtube. I never stated anywhere in this entire thread that the A91 wouldn't have the B58D. I merely pointed out that the A90 whp numbers are the same as the B58D in the M40i.
Then you should know that the A90 has outperformed the US spec model Z4 M40i both on track and on the dyno to. Lower compression can't win when both motors are running the same boost.

382hp is still 382hp
A car can have a different tune on it's ECU with the same block and and variation of internals however, if it's tuned to 382hp it's still 382hp. Difference is in compression though something I think you continue to overlook. The higher compression on a turbo motor doesn't need as much boost to make the same power and torque, has virtually no turbo lag and makes more power on bottom end which is what most people want for the streets. Most of us have had the low compression 1,000hp dyno queen that takes 15 seconds to spool and still runs an 11 second 1/4 mile. They're completely useless on the streets. The BMW Z4 is not a grand touring car either, it's a sports car.

Just give up and ignore him. You're talking to a door knob. He doesnt understand that the the 382 on the 2021 can also be under rated like the 335 was on the 2020.
You missed the point entirely. The B58D in the 2020 Z4 M40i is running a larger turbo and a higher factory boost pressure than the B58C in the A90 MKV Supra. If we were to place the exact turbo and run the exact boost pressure as the B58D on the B58C it would make more power and torque. Compression wins this debate. Heads and manifold of the B58D will help with flow about 3% over however that's not where the major power is being made on these blocks, it's coming from boost.
Precisely! So given that the B58D has a larger factory turbo and is factory set to a higher boost pressure is the only reason for the variable between the two engines in regards to horse power ratings being pushed on the net. The B58C will never have to run as much boost nor will it ever experience the lag of the B58D, and it will make it's torque earlier in the rpm band (sweet spots). If we were to run a Pure 800 turbo on both a B58C and a B58D with the same fuel and boost pressure the B58C is going to make more power period, despite the B58D have a traditional manifold and different head.
Operational costs silly. It's cheaper and more profitable. When you run a business some day you will understand LOL.
Jordan Tsang don't you have some shoes to go collect?
Wow get this clown a trophy and a gold star. At least you can feel like you won something in life. Automotive forums deadlier than Covid-19
Do you even own a Supra? Didn't think so.
