It is really funny and sad at the same time how a simple question could generate 2 pages without one single relevant reply. I didn't ask for turbo, about speed of shifting, what is faster and definitely not if Camry is faster.

The question was: why - and even if - AT drops power at hi-rpm, and where the AT loses power when the transmission is locked. It was a genuine technical question.

Now, JDM4E, that IS a valid technical question.

Maybe, just maybe, NOBODY knows ...... :iono:

they answered that in the very first reply. The gearing and final drive are different, more suited to highway cruising.

After the obvious answer it is all about going as far off topic as possible. That is how we roll.

Yes, it does, a tiny bit.

Ive been very happy with my Edelbrock boosted, e-85, automatic FRS. 0 to 60 in 4.9 and I love the way it shifts on the track.

Any verification to this claim, as I'm a fellow AT 86er about to go boosted....

I won't be in the market for a while, but they've given me more solid numbers to ponder than anyone else to date. They've tried it all. I'm sure many others have as well but these guys are local to me. I'll use them moving forward.

AT has about 2% more drivetrain loss or roughly 18% vs 16%. Drift office baselines where 164whp vs 168whp, It does appear they make peak power at the same rpm but for some reason the AT does drop off quicker after. Not sure why this would be, maybe something in the tune and can be tuned out. Mine doesn’t feel like it has such a noticeable drop off if any. My tuner also changed a lot of things with the AT. But i have never dynoed to know for sure if I know longer have this drop off.

The biggest difference is MT can launch, and 3-4-5 gears are essentially our 3-4 gears so mt has much closer gearing. Without launching they are almost identical 0-60 though, then the gearing the MT ever so slowly crawls away. A FD swap can mitigate some of the gearing disadvantage. Also the auto has been known to hold up to a lot more power then the MT.

Either way modifying either MT or AT car will yield roughly the same benefits.

I was under the same impression that an AT can handle way more power... Unfortunately that isn't entirely true, nor the facts are very positive at all...

Our AT is called A960e, it is used in the IS250 and several other cars, and the max torque it can handle is 300nm/221ft⋅lb Only!*
The other issue is that the options to beef it up is almost none existing.
