If your talking to me, I would drop to 3rd, then boost is pretty instant.

I haven't drove much with the new turbo to say much on it.

I also have rolling launch, so I have full boost without accelerating, and can launch with zero spoolup time.

For the same reason, a 550whp A90 supra will pull on a 700whp A80 supra.
is it possible to make that much power carb legal on an a90? I just sold my brz for a c6 to make that kind of power...still have the elise though

The only CARB legal power is stock. However, you can make maybe 20hp less on a stock cat compared to catless... and still pull on a C6Z with ease.

Would the stock exhaust system (with cat deleted ) of the brz affect much in terms of both performance and reliability standpoint?

Thanks for the answer, Mike. A90, yes. Hiw about cruising in 8th then drop the hammer. Already having shifted to 4th doesn't count. I want to know response from off boost and off gear since that's where I am most of the time on the street. I read the transmission can shift from 8th to 4th no problem. 200ms, but then that will probably delay building boost even more. Responsiveness compared to an EV is what I care about.

Stock top gear 50 to 70 is 2.8 seconds. Model y is 2 seconds. Do mods knock a half second off that, or is it a lot of shift time?

If you had to prescribe one platform or the other to an 18 year old who loves Californian YouTubers, has 6 figure budget and wants 750whp with hellaflush, which would you pick?

With a tune, it would gain some power. Zero reliability impact with a good tune.

By the time the downshift has happened, boost is already at full.

Yes, the trans can and will skip gears.

Cruising in 8th is still within spool window; I can have full boost at ~1800 rpm, even with my increased power.

Not an accurate comparison. The Model Y has a top speed on 135mph with 1 gear.

That would be equivalent to approximately 5th gear in the supra, but lets use 6th for posterity.

My 60-80 time in 5th gear only is ~1.4s, and 6th gear only ~1.65s. I've not tried 50-70.
