The Twins better with 5 speed box?
 
I was thinking would the frs/brz be better with a one less gear? I remember back in the day before the CVTs most subaru were 5 speed.

5 speed gear pros:
-better power band?
-quicker acceleration
-easier in traffic (manual)
cons
-less mpg


what do you guys think?

no.

Why not go hog wild and just have 3?

All cars, not Subarus.

How? No.

See above.

Ok, maybe slightly, but still....... no. Because it's a manual and you should enjoy shifting if you own a manual. This isn't a big torquey V8 with long gearing and low end power.

The difference in MPG efficiency isn't really worth thinking about. The specific engine and how hard you drive the car will be much more important to your MPG.



The one actual criticism is that 5 speeds tend to be slightly stronger. The S15 6-speed vs the S13/14 5-speed debate is a good example...... but, in reality, neither will be strong enough for people making big power, so it doesn't really matter all that much.

I'd always rather have the 6 speed.

Exactly, for years we got along just fine with 3 speed MTs. The first AT in Chevrolets had only two speeds.

When I had my 06 Miata, I got along just fine with a 5 speed MT, and it had less power than the FR-S.

What I would like to see come back is the old Ford type "overdrive" ..... http://www.runemasterstudios.com/gra...s/driving2.gif

Just for historical knowledge (and my learning), would 3rd gear be overdrive? Or was there no such thing back then?

8R6 06-25-2015 09:37 PM

power band being "better" depends on the engine tuning in conjunction with the gearing... but that said, a similar 5-speed compared to a 6-speed on a same car will most likely have taller gearing than the 6-spd, resulting in slightly slower acceleration since we dont have much power to begin with.

Hell, not just the first but clean up into the early/mid 70s.

Can you provide any documentation to support these statements?

-easier in traffic (manual)

I really don't see why that would be true.


cons
-less mpg


what do you guys think?

My first mustang had a 3 speed manual, made picking a gear pretty trivial :bellyroll:

But really, I don't think you can find anyone to argue that a 5 speed gearbox would be better unless it was geared for a specific reason

GreenMonster 06-25-2015 09:46 PM

Even w/ a 6 speed, I still find myself occasionally trying to shift into seventh :)

Back in the day, in most 3 speed MTs, the 3 gear was NOT overdriven ..... it was 1:1.

Some drivetrains had an "overdrove" unit that would make the ratio to the differential less than 1:1.


And, of course, we always have had the "Georgia overdrive" ....... :D

No. The 3rd gear was just a very long gear. Some came with OD as well though.

bcj 06-26-2015 01:58 AM

OD was a set of gears after the transmission that could be engaged to make the driveline turn faster than the engine crank.

"Overdrive Transmission" on wikipedia has a pile of info.
