because maf has better control over fuel mixture at different areas as long as the maf transfer function is tuned properly.
Good idle control, just set your commanded lambda you want. Very good driveablity compared to SD setups that I've done. For a daily driven car I rather use maf then SD.
depends on location of the maf.

There is gonna be a difference in how much extra timing you can throw in at lower gears.
dude.
with the above dyno I posted, I spun 225 NT-01 in 2nd gear the whole straight at autocross. That's with 3.9 rear end and a 6 speed. You need like 275 slicks to do ANYTHING with that amount of torque in low gears.

4th gear rolls are great though

Right now you have neither, so unless you've driven other cars, you have absolutely nothing to base your opinion off.
not sure if I awnsered this eariler.

335i test driven, very responsive oem car.
rx7 FD v8, very quick very fast, tq everywhere
I plan to test drive the merc c250 soon enough.

the 335i and the rx7 were awesome in application.
They would just go any any point in the powerband.
of course one is a inline 6 twin turbo the other is a v8 but my point still stands that the useful tq everwhere helps the car overall no matter where you are at.

I think you're the first person in the history of the world to say that a rotary has torque, much less anywhere but 150000000000 rpm.

1) compound boosted direct injected inline 6
2) 5.7L v8

Yeah, you'll definitely replicate that with a 1.6 BP made 20+ years ago

I dont understand why youre still trying to break the laws of physics. Either change your mind, get more displacement/I6/V8, or get a GT12. What youre looking for wont happen with an engine that has less than 100 ci that was designed and built in the 80s

Ok, no v8, no blower, you must do it with a turbo. Buy the smallest BW EFR turbo they make and put it on a short runner tubular turbo mani, run the lowest volume of charge piping and intercooler you can get away with and use the electronic boost control to get a boost spike as soon as possible and taper it off to protect the engine.
