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 .459
3rd - 1.333 .303
4th - 1.028 .228
5th - 0.820 .203
Rev - 3.583

random latest ND miata mx 5:
5.087
2.991 .412
2.035 .320
1.594 .217
1.286 .193
1.000 .222

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
*
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

QUOTE(dares @ Dec 19 2016, 09:24 AM)
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.

mind to share the ratio here?

APA BENDA PERSONA WITH MX5 ?

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

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

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

You 2.0 already 3rd should be enough power right?

4B10 and no skill driver, 2nd not enough rpm, 3rd not enough power cry.gif

Ya tempted to change, but 5k km only, thinking to just let it wear along with the chain, change only when replacing the chain XD

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

New Persona came with a tiny 185/55/15 wheel
The ratio are as follows

1st - 3.636
2nd - 2.045
3rd - 1.414
4th - 1.051
5th - 0.756

Rev 3.615

FD 4.250

By the way I'm always curious about what makes the maker to decide to have a Long FD + Short gear ratios combination VS Short FD + Long gear ratios hmm.gif

If I were to guess /assume, overall driving feel (probably between prototype testings and what not, complex calculations between top speed and acceleration, Rev hangs, percentage or actual value of rpm changes between shifts, power band, engine (especially vvt or lifting mechanism involvement) characteristics including ECU behavior varying engine load etc.

Dear MT sifus, I notice the gear knob is facing the passenger side 45 degrees, they did that on purpose?

Yeah now I realize it's not locked after some driving it will face other direction

It might fall off if I got too excited with driving?

Hey there, anyone of u guys persona fuel consumption goes to 7.1L/100km?

Mine seem increasing with every services.. before service was 6.8-6.9

Wat could be the problem?

6.8,6.9 to 7.1L is too subjective.

thinking ur way of driving, traffic which can't be 100% same. unless after service it jump to 11 - 12L then it could be some problem

Petronas syntium 3000 about 7.1
Now using Mobil 1 drop to 6.5
