Ferrari and superbike (i am going to assume literbike/supersports or mid range supersports lol) are kinda... a level above than most average sports car no?

wide power band sure, however the focus tends to be more towards low/mid end for regular family sedan because well, it is supposed to be a family sedan. however i guess it does have the perception of wide power band due to the perception of VVT that almost every modern car has today?

that said, i'm actually ok with CVT especially with the likes from Subaru.
i just personally have a bias with manual just for the sheer fun of it and you know, having a third pedal so every part of me is doing something.

like my 250cc kapchai bike... to corner aggressively, left hand clutch, right hand brake, left leg downshift, right leg brake (one could argue that good riders don't bother rear brakes, but i'm not good and i only ride a small bike so eh tongue.gif), then also have to move my butt off the bike...  like suddenly very busy  rclxub.gif
it just dawned me, even with short ratio boxes, its either there's plentiful of revs to play with, or they still kept at least 1st gear quite long hmm.gif
though, usually at least 2nd gear's ok to downshift into for short ratio gear boxes unlike inspira where its just downright nerve wrecking, positively or negatively.

the persona imho seemed worse, albeit if you could somehow unlock more revs to play with... at the risk of lol campro masuk bengkel... but i digress sweat.gif
but yes, it is a bit unfair to compare a remapped 4B10 vs S4PH

i wonder what persona ratios are running? inspira:
1st - 3.538
2nd - 1.913
3rd - 1.333
4th - 1.028
5th - 0.820
Rev - 3.583

random latest ND miata mx 5:
5.087
2.991
2.035
1.594
1.286
1.000

final
2.866

the first gear and final drive is like a huge fuck you, but i guess how 2-6 is decently quite close... oh well all is forgiven? lol
lol no overdrive though

Because the final drive of the ND is long, the result is actually not much different from my 6 speed econoshitbox lowlife Ford even though the ratios of the MX5's gearbox are shorter.

From what I read, it has a 1:1 top gear so to reduce friction and transmission loss due to different gear sizes, hence improving efficiency and fuel economy during highway cruising. The rest of the gears (as well as the final drive) were adjusted accordingly to accomodate that final gear ratio.

APA BENDA PERSONA WITH MX5 ?

yes you need to look at the overall .. not just the number at the gears..

not much difference actually...closer but not much

looks at EVO 8 MR gearbox
2.909
1.944 .332
1.434 .263
1.100 .233
0.868 .211
0.693 .202

only around 20% rpm drop
mind to share the ratio here?
nope...just the difference between ratio..

same said changing final drive will make it feel like close ratio gear box...its not...
*
refer to my gear ratio calculation.
in fact yes .. if you change the final drive to much bigger it will be like close ratio ..
Gear Ratio Calculation

you need to take account of the speed the car doing to show the RPM drop.
let me google up the mx5 spec and do one for you

you are right.. im getting old .. laugh.gif

the FD impact is too small to be seen actually..

anyhow the miata gear ratio is acceptable to me ... 4 gears onwards the rpm drop is around 1k only ..
at 2 - 3 about 1.5k .

quite short if u ask me

kinda weird ratio....
we dont measure by how much rpm drop
as it depends on the max engine rpm
bike engine tends to have bigger rpm drop, due to very high rpm..but then their ratio are much closer..

thus we measure by using % of rpm drop...
*
i actually dont use % .. i see where it drops which is more important.. as long as it falls within the power band then it is good enough
fake lancer .. the manual .. 2-3 that one a bit bangwall.gif especially when up genting ..

I think have to go with what sifu Kenny said leh,  else kena diao further sad.gif
But yeah,  I've read similarly as well and the reason of not having an overdrive 6gear with the long final drive combined due to the overall goal of the car being a fun open top touring /Canyon trip haha.

I suppose if you want to make it even more aggressive,  the final drive is probably one of the main things you can tinker with hahaha
Sorry boss just bring random sad.gif

your R25 .. the rear spoket settle jo la .. bigger (more teeth) .. more pickup
smaller (less teeth) .. more top speed
